A brief general introduction to PROFIBUS is provided, followed by sections including important instructions regarding ordering, configuring and start-up for each circuit-breaker type. The universally applicable PROFIBUS guidelines as specified by the PROFIBUS User Organization (PNO) are included in the Appendix and can be used for planning your overall PROFIBUS-capable system. Further detailed information on PROFIBUS and PROFIBUS system components can be found in the following catalogs: IK 10: "SIMATIC NET - Industrial Communication" Order number: E86060-K6710-A101-A7-7600 ST 70: "SIMATIC - Components for Totally Integrated Automation" Order number: E86060-K4670-A111-A3-7600 ST PI: "PROFIBUS & AS-Interface - Fieldbus Components" Order number: E86060-K4660-A101-A2-7600 1.2 Explanation of terms and advantages of "communication" Ever increasing levels of automation mean a higher demand for information regarding the state of systems and their components (e.g. evaluation of measured values and diagnostic data). In addition, it is also important that field devices can be controlled directly from control rooms, thus minimizing the personnel costs required for intervention in automation processes. The installation of a bus system allows for a simple data exchange between field devices (e.g. 3WN6 circuit-breakers) and PLCs (e.g. SIMATIC S5/S7 PLCs). Whereas conventional wiring technology requires many multicore control cables connected in parallel to perform this communication task, a bus system generally only requires a single 2-core cable. This means that substantial savings can be made in the areas of wiring (shorter installation time), testing and control cable costs. In addition to controlling the field devices, measured values, signals and diagnostic data which can indicate faults/problems in the plant at an early stage can easily be transferred, thereby helping to reduce system down times (especially through preventive maintenance). The monitoring of current values can ensure that the system is utilized economically at all times (energy management). The communication-capable circuit-breakers 3VF (25 - 800 A), 3WN6 (up to 3200 A), 3WN1 (up to 6300 A), and 3WS1 (vacuum technology up to 2500 A) take full advantage of communication via a bus system. The bus system used is PROFIBUS-DP (EN 50170). It permits circuit-breakers to be controlled and monitored, or even remotely parameterized, depending on the type of overcurrent release fitted. Two high-performance software packages are available for the visualization and evaluation of transferred data (see page 35 for description): 1 * "Win3WN6" (for start-up, and for operation and monitoring of circuit-breaker 3WN6) * "SICAM LCC" (visualization of complete systems with circuit-breakers 3VF, 3WN6, 3WN1, 3WS1, and with SIMOCODE-DP motor protection and control device) 2 1 2 4 Shipping of Win3WN6 starts in 07/98.

Version1.0 (05/98) Communication System Manual 3VF, 3WN, 3WS Circuit-Breakers 1.3 Explanation of terms "PROFIBUS" and "PROFIBUS-DP" PROFIBUS3 (PROcess FIeld BUS) is a standard (EN 50170), supplier-independent field bus system. Over 250 suppliers are already offering more than a total of 770 PROFIBUS products in their product ranges. There are in excess of 500,000 PROFIBUS nodes installed worldwide, and PROFIBUS users are supported worldwide by user organizations in 12 countries. PROFIBUS consists of a 2-core cable over which signals (bits) are transferred between PLCs and field devices in a standardized format (protocol). Up to 125 field devices can be connected to a single PROFIBUS network. Repeaters can be used to connect bus segments making it possible to span distances greater than 9 km using copper cables and distances up to 100 km using fiber optic cables. The length of the individual bus segments depends on the baud rate and whether or not there are slaves present (see Table 1). This means that different numbers of repeaters will be used depending on the type of network. Data rate (Kbit/s) 9.6 19.2 93.75 187.5 500 1500 12000 Segment length (m) with slaves 1200 1200 1200 1000 400 200 100 Segment length (m) without slaves 3300 2800 2000 1600 1200 400 - Table 1: Ranges of PROFIBUS network segments (2-core cable) In addition to standard linear bus networks, it is also possible to utilize fiber optic technology together with optical link modules (OLM ) to form redundant ring structures. There are at present two forms of PROFIBUS: PROFIBUS-DP (Decentralized Peripherals) and PROFIBUS-FMS (Field Message Specification). PROFIBUS-FMS allows for supplier-independent communication between PLCs. Communication via the FMS user interface puts functionality rather than reaction time into the foreground. Special user services are therefore available for the logically structured data exchange of even very large amounts of data. Very fast reaction times for a medium data volume are required for communication with field devices (e.g. 3WN6 circuit-breakers, SIMOCODE-DP). This can be achieved by PROFIBUS-DP. The typical configuration of a PROFIBUS-DP network is as a mono-master system, i.e. the slaves are addressed by a single master. The openness of PROFIBUS offers many connection possibilities: a special interface (DP/AS-i link), for example, allows the connection of Actuator-Sensor Interface (AS-i) network systems to PROFIBUS-DP networks. All major PLC suppliers offer PROFIBUS-DP masters. 3 Siemens originally referred to PROFIBUS as SINEC L2. Version 1.0 (05/98) Copyright Siemens AG 1998.

A small selection of the products available from the Siemens world of communications is shown below in Figure 1. Needless to say, PROFIBUS-compatible non-Siemens devices which are in conformance with the PROFIBUS standard can also form part of this system.

All rights reserved. Version1.0 (05/98) Communication System Manual 3VF Circuit-Breakers 2 3VF circuit-breakers 2.1 Design and mode of operation 2.1.1 Communication via PROFIBUS-DP 3VF circuit-breakers can communicate via PROFIBUS-DP by means of SIMOCODE-DP (Siemens Motor Protection And Control Device - Decentralized Peripherals, or product code 3UF5). This communication-capable branch is available for currents from 63 A to 800 A for circuit-breakers 3VF3 to 3VF7. The circuit-breaker assumes the tasks of overload and short-circuit protection for the plant section. SIMOCODE-DP measures the current in the feeder in the highest loaded phase and makes it available via the bus. The customer wires control functions such as opening/closing (ON/OFF) and monitoring of the switching state (whether the circuit-breaker is ON or OFF or whether it has tripped due to a fault) between SIMOCODE-DP and the circuit-breaker (see section entitled "Connecting 3VF to the communication system"). The motorized operating mechanism and internal accessories, such as alarm and auxiliary switches, must be taken into consideration when ordering the circuit-breakers. (See section entitled Selection and ordering data). SIMOCODE-DP (3UF5) acts as a control and measuring unit in conjunction with the 3VF circuit-breaker. The overload and short-circuit protection functions are not affected by the connection to SIMOCODE-DP or by a PROFIBUS-DP failure. SIMOCODE-DP measures the following operational data as standard and makes them available via PROFIBUS-DP: Maximum phase current as a % of the setting current in the highest loaded phase: (Prerequisite: Setting current Ie of SIMOCODE-DP corresponds to setting current or rated current Ir of the circuit-breaker. This value must be entered prior to start-up in the field "Setting current 1".) Operational state of circuit-breaker (ON/OFF/TRIPPED = trip due to overload or short-circuit). Event signals: I>In Signal at upper current limit, default setting of 120 %, can be parameterized. I<In Signal at lower current limit, default setting of 80 %, can be parameterized. The following control commands are possible via PROFIBUS-DP: Switch circuit-breaker ON/OFF RESET circuit-breaker following overload or short-circuit Version 1.0 (05/98) Copyright Siemens AG 1998.

All rights reserved. Version1.0 (05/98) Communication System Manual 3VF Circuit-Breakers PROFIBUS-DP uses different data channels in order to maintain fast transmission times. In this way, up to 12 bytes can be transferred at regular intervals from SIMOCODE-DP to the automation level and up to 4 bytes can be transferred back. The 20 bytes of diagnostic data are only transferred from SIMOCODE-DP to the automation level in the event of a change, i.e. the diagnostic channel is event-triggered. The 213 bytes of parameter data are only transferred to SIMOCODE-DP when the automation system is started up. SIMOCODE-DP can operate in conjunction with any standard PROFIBUS-DP master which is capable of reading type or GSD files and which can process the following volumes of data: * * * * 4 bytes of control data cyclically from the DP master to SIMOCODE-DP 4 or 12 bytes of signal data cyclically from SIMOCODE-DP to the DP master 20 bytes of diagnostic data acyclically from SIMOCODE-DP to the DP master 213 bytes of parameter data In order to guarantee optimum data transfer times, the large volume of SIMOCODE-DP input and output data is divided into two transfer modes on PROFIBUS-DP - cyclic and acyclic transfer modes: 1. Cyclic data traffic: cyclic data (e.g. actual maximum phase current ILmax in the highest loaded phase) correspond to basic information which is transferred at regular intervals. Important information is automatically transferred from the circuit-breaker to the I/O area of the bus master in this way. Similarly all the important (cyclic) data contained in the I/O area of the bus master are also transferred to the circuit-breaker. Cyclic input data include, for example, the setting current value for overload releases (setting current Ir), as well as the circuit-breaker remote ON/OFF command. Cyclic output data from SIMOCODE-DP include the switching state of the circuit-breaker (ON/OFF), as well as various group signals which can indicate whether a fault (e.g. trip due to overload or short-circuit) or a warning (e.g. current warning, 80 % or 120 %) is present. 2. Acyclic data traffic: Acyclic data are only transferred from the interface to the bus master or from the bus master to the circuit-breaker when a request is transmitted. This means that specific messages are sent from the bus master to the 3VF circuit-breaker when required. Version 1.0 (05/98) Copyright Siemens AG 1998.

This parameter file defines the base type, slave address, baud rate, the control and message bytes, and the inputs and outputs in accordance with the standard circuit diagram. This file is included in the Win-SIMOCODE-DP software from 06/98 and can also be downloaded from the Internet at the address "http:\\www.ad.siemens.de". You can parameterize SIMOCODE-DP via the RS-232 interface using the handheld operator panel or using the Win-SIMOCODE-DP software which is provided. We recommend that you use the SIKOSTART system connecting cable (order no. 3RW2920-1DA00) for connecting the PC or programming device to the SIMOCODE-DP system interface. Another possibility instead of using Win-SIMOCODE-DP is offline parameterization via COM-PROFIBUS or STEP 5/STEP 7. For offline parameterization, the required data are stored on a memory card with the help of a programming device. This plug-in card is installed directly in the host (PLC master) and is read by the master, e.g. IM308C, on start-up. Version 1.0 (05/98) Copyright Siemens AG 1998.

Check that all the system components are fitted Check that all the following system components are fitted before connecting 3VF to PROFIBUS-DP: 3VF circuit-breaker with internal accessories (alarm switch, auxiliary switch) and motorized operating mechanism Note: The motorized operating mechanism is needed for remote control of the circuit-breaker. If this is not fitted, the circuit-breaker cannot be switched ON and OFF via PROFIBUS. The measurement and warning functions are operational, however. Suitable SIMOCODE-DP basic unit (cf. Selection table, page 17) Connecting cable for parameterization using a PC or notebook Diskette with type or GSD file (supplied with SIMOCODE-DP manual) Parameter file (included in Win-SIMOCODE-DP from 6/98) Win-SIMOCODE-DP software or 3WX36 handheld operator panel COM-PROFIBUS software, only required for parameterization via PROFIBUS-DP 2.) Check the system requirements The second step involves checking the following requirements for connecting 3VF to PROFIBUS-DP: The 3VF circuit-breaker must be installed and wired in accordance with the circuit diagram on pages 14/15. The PROFIBUS-DP master must be present and operational. SIMOCODE-DP must be correctly configured and installed (cf. user guide). 3.) Connect SIMOCODE-DP to PROFIBUS-DP The bus cable can be connected to the SIMOCODE-DP 9-pin SUB-D connector using the standard PROFIBUS-DP connector (order no. 6ES7972-0B.10), or it can be connected directly to the screw terminals labeled "PROFIBUS-DP". 12 Copyright Siemens AG 1998. All rights reserved. Version1.0 (05/98) Communication System Manual 3VF Circuit-Breakers 4.) Connect SIMOCODE-DP to 3VF circuit-breaker If the following accessories are not already fitted in the 3VF circuit-breaker, fit them before wiring: 3VF accessories Function and mode of operation Alarm switch (AS) For "Tripped" signal on overload or short-circuit Auxiliary switch (HS) Switch position of circuit-breaker Motorized op. mech. (M) For remote ON/OFF commands Please follow the assembly instructions when fitting internal accessories in the circuit-breaker. Connect SIMOCODE-DP and the 3VF circuit-breaker in accordance with the circuit diagram on pages 14/15. 5.) Bus configuration and visualization The handheld operator panel or a PC must be used for setting a number of parameters in SIMOCODE-DP during the initial start-up, e.g. address and baud rate. The remaining parameters can then be set via the bus using a PC or programming device and either the COM-PROFIBUS software or STEP 5/7. The parameters are then stored on an EEPROM. If SIMATIC S5 is the bus master, the bus can be configured quickly and easily using either a PC or a SIMATIC programming device (PG) in conjunction with the COM-PROFIBUS program. In the case of other bus masters, the appropriate devices and/or supplier-specific tools must be used. The SIMOCODE-DP identification can be read into the bus master in the form of type or GSD files. The following list specifies which file is required for each master: File allocation list:4 si8031_d.200: Type file (German) for Siemens master only (e.g. IM308C ...) si8031gd.200: Type file (German) for Siemens master only (S5-95) siem8031.GSD GSD file (device data) For non-Siemens suppliers of standard DP masters Note: You only need a GSD file if you are operating SIMOCODE-DP in conjunction with a DP master which cannot process type files. High-performance software is available for the visualization and evaluation of the data transferred from 3VF (see page 35 for description): "SICAM LCC" for the visualization of complete systems implementing circuit-breakers 3VF, 3WN6, 3WN1, 3WS1, and a SIMOCODE-DP motor protection and control device. 5 4 5 The type and GSD files are also available under the following modem number: 0911-737972 Shipping of SICAM LCC starts in 10/98.

All rights reserved. 25 Communication System Manual 3WN6 Circuit-Breakers 3 3WN6 circuit-breakers 3.1 Mode of operation and design 3.1.1 General mode of operation of 3WN6 circuit-breaker communication via PROFIBUS-DP The 3WN6 circuit-breaker is communication-capable when fitted with an overcurrent release version D, E/F, H, J/K, N or P together with "additional functions 2" and a communication module (order supplement Z=F01). Overcurrent releases N and P can also be fitted with a communication module with measurement functions instead of the simple communication module (order supplement Z=F05). This module offers an extended range of functions (cf. Fig. 3, page 26). The connection of the 3WN6 circuit-breaker to PROFIBUS-DP is implemented by means of the DP/3WN6 interface module. The information available on the overcurrent release is transferred to the interface via the 3WN6 communication module (Z=F01) or the communication module with measurement functions (Z=F05). The interface then translates these 3WN6 signals to the PROFIBUS protocol. The interface similarly translates all the control and parameter signals which are sent from the bus master to 3WN6 via PROFIBUS from the PROFIBUS protocol to the 3WN6-specific protocol. Following the initial connection of 3WN6 to PROFIBUS-DP (see section 3.3, page 31), the user has no further tasks to perform, i.e. communication is automatic. 3.1.2 Hardware and software requirements The following hardware and software items are required in order to communicate with 3WN6 via PROFIBUS-DP (cf. Fig. 3, page 26): P C / P r o g r a m m in g U n it (w i t h C O M P R O F I B U S 6 S o ftw a r e ) 7 PLC = PC/PU Type-/DSDData ( s u p p lied w ith DP/3WN6) 2b GatewayDP/3WN6 (3RK1000) Plug 6ES7 2 3 PROFIBUS-DP = 5 DP/3WN6 S o ftw a r e m o d u l e f o r S IM A T I C S 5 , S 7 Connection cable 3WN6-DP/3WN6 (3 m , s u p p l i e d w i t h DP/3WN6) 24 24 V-DC V-DC P o w e r S u p p ly 4 Power supply for closing coil (Y1) and shunt release (F1, F2) 2a 3WN6 Overcurrent unit D, E/F, H, J/K 1a N or P Overcurrent unit N or P + Addn Funct. 2 Circuit-Breaker 3WN6 1 1b +Comms m odule F01 1c Current measurement, S ig n a lling , .. 1a + Addn Funct. 2 + 1b Comms Module w i t h M eas.function 1d F05 Energy Management S ig n a lling , ...

Version1.0 (05/98) Communication System Manual 3WN6 Circuit-Breakers Hardware: -Communication-capable circuit-breaker 3WN6 (no. 1): Overcurrent releases D, E/F, H, J/K, N or P (no. 1a) are communication-capable when fitted with "additional functions 2". (no. 1b). Unlike a standard 3WN6, a communication-capable 3WN6 circuit-breaker has a communication module (no. 1c). When additional measurement functions are required (e.g. voltage, frequency, power), a communication module with measurement functions (no. 1d) must be ordered instead of the simple communication module. (Please refer to section 3.2, page 28 and section 3.1.1, page 37 for a description of the functionality of the overcurrent release when combined with a communication module/communication module with measurement functions.) -Order number:6 - The type of overcurrent release ("D"..."P") can be determined from position 10 of the circuit-breaker order number; enter a "7" in the eighth position of the order number if the circuit-breaker is to be fitted with "additional functions 2". - The order number supplement for the communication module is "Z=F01". - The order number supplement for the communication module with measurement functions is "Z=F05" instead of "Z=F01". Example: For a draw-out circuit-breaker, complete with guide frame with overcurrent release "P", "additional functions 2" and a communication module with measurement functions, the order number is 3WN6 ......-7.P....-....-Z with Z=F05 +... Note 1: If the draw-out circuit-breaker and guide frame are ordered separately, 2 order numbers are required. In the case of a draw-out circuit-breaker without a guide frame, the sixth position of the order number is "7": Circuit-breaker order number: Frame order number: 3WN6.7.-7....-....-Z with Z=F01 or F05 3WX3683-.A..0-Z with Z=R39 + ... Note 2: The position signaling switches cannot be ordered separately with communication-capable draw-out circuit-breakers. They are included in the scope of supply and are located on the position display unit (bottom right) of the circuit-breaker. Note 3: In order to remotely close a circuit-breaker via PROFIBUS, the circuit-breaker must be fitted with a motorized operating mechanism and closing solenoid (Y1). To remotely open a 3WN circuit-breaker via PROFIBUS, the circuit-breaker must be fitted with a shunt release of the type F1 or F2. The possible switching commands are illustrated in Fig. 5, page 32 and Fig. 6, page 32, Step 2. - One DP/3WN6 interface module for each 3WN6 circuit-breaker (no. 2).7 Order number: 3RK10 00-0JC80-0BA1 - A connecting cable from the SUB-D socket on the DP/3WN6 interface module to the SUB-D socket of the 3WN circuit-breaker (no. 2a). This cable is a standard 9-pole cable (1:1 connection) with a length of 3m and is supplied with the interface. - Connection from the "PROFIBUS-DP" terminal of the DP/3WN6 interface module to PROFIBUSDP (no. 3). Two standard connectors are available for this purpose: Order number: 6ES7 972-0BB20-0XA0 (for baud rates up to 12 Mbaud) - 24 V DC voltage supply (in acc. with DIN 19240; no. 4). Order number: 6 7 4AV2... or 4AV3... (See NSK catalog, section 16). cf. Table 3, page 30 for examples of circuit-breaker order numbers. Interface "DP/3WN6" was previously also referred to as interface "DP/RS485" and "kNS/DP". Version 1.0 (05/98) Copyright Siemens AG 1998. All rights reserved. 27 Communication System Manual 3WN6 Circuit-Breakers Software: - 3.5" diskette with type/GSD file for the software connection of 3WN6 to PROFIBUS-DP (bus configuration). This diskette (no. 2b) is supplied with the interface. Step 6, page 34 outlines which file is to be used for which master. - Bus master software for communication control. In order to communicate with the SIMATIC S5/S7 as bus master, a standard software block (no. 5) is required (see page 59 for a description of this module): Order number: 3RK1800-0AA00-0AA0 For the initial connection of a 3WN6 circuit-breaker to PROFIBUS-DP, the following hardware and software components are additionally required:8 - A programming device (e.g. PG 740), or PC with the appropriate software (e.g. STEP 5) (no. 6) - COM-PROFIBUS (no. 7) for the 3WN6 software interface (bus configuration) to PROFIBUS-DP. 3.2 Bus connection functionality 3WN6 output data can be read via PROFIBUS-DP: - Circuit-breaker key data (e.g. circuit-breaker type/size, overcurrent release version) - Operational states (e.g. switching state, "Tripped" signals, processor status) - Operational data (e.g. actual phase current IL1)9 - Protection parameters (e.g. setting current Ir for overload release) ... and input data can be written to the circuit-breaker: - Execute switching action (switch circuit-breaker ON or OFF) - Set protection parameters (e.g. setting current Ir for overload release) - Set additional functions (e.g. switch phase sensitivity ON/OFF) 8 9 28 With SIMATIC S5 as master. Use appropriate hardware and software components specified by the supplier for other, especially non-Siemens, masters. Because of the way current transformers work, only currents at the communication module (Z=F01) which are greater than 18 % of the rated circuit-breaker current (In) are displayed on the release or transferred via the bus. I = 0 applies below 18 %. Transfer always takes place in the case of the communication module with measurement functions (Z=F05). The measuring accuracy (above 18 % In) is +/-5 % of the measured value for the communication function (Z=F01) and +/-3 % of the measured value for the measurement function (Z=F05). Below 18 % In. (at the measurement module), the measured values are not identified due to "noise". Copyright Siemens AG 1998. All rights reserved. Version1.0 (05/98) Communication System Manual 3WN6 Circuit-Breakers In order to guarantee optimum data transfer times, the large volume of 3WN6 input and output data is divided into two transfer modes on PROFIBUS-DP: cyclic and acyclic transfer modes: 1 8 8 bytes of acyclic data 9 12 4 bytes of cyclic data Fig. 4: 12-byte I/O channel for 3WN6 1. Cyclic data traffic: cyclic data (e.g. actual maximum phase current ILmax) correspond to basic information which is transferred at regular intervals. Important information from the circuit-breaker is automatically transferred from the DP/3WN6 interface to the I/O area of the bus master in this way. Similarly all the important (cyclic) data contained in the I/O area of the bus master are also transferred to the circuit-breaker. Cyclic 3WN6 input data include, for example, the setting current value for overload releases (setting current Ir), as well as the circuit-breaker remote ON/OFF command. Cyclic output data from 3WN6 include the switching state of the circuit-breaker (ON/OFF), the 3WN6 ready-to-close signal, as well as various group signals (group fault signal, group warning signal, group error signal) which can indicate whether a fault (e.g. trip due to overload), a warning (e.g. current warning) or a processor error is present. 2. Acyclic data traffic: Acyclic data are only transferred from the interface to the bus master or from the bus master to the circuit-breaker when a request is transmitted. This means that specific messages are sent from the bus master to the 3WN circuit-breaker when required. Acyclic data from 3WN6 (i.e. data which are requested given certain conditions) include, for example, the position state of the circuit-breaker (e.g. test or connected for draw-out circuitbreaker). In order to determine the cause of a group signal, for example, (see above), the actual cause is determined by means of an acyclic message. In the case of a group fault, for example, it is possible to determine whether the cause is due to a "g" release (earth fault), a "z" release (delayed short-circuit), an "n" release (instantaneous short-circuit), or whether there was another cause for the release. Acyclic data written to 3WN6 include, for example, the setting values for "z" release, "n" release or current phase imbalance. When used in conjunction with a communication module with measurement functions (Z=F05), additional setting values can be written, e.g. undervoltage release, overvoltage release or load shedding signals. The message list in section 3.4, page 37 describes in detail the functionality of the various overcurrent releases on PROFIBUS-DP. This will allow the user to select the required overcurrent release together with the correct communication module (Z=F01) or communication module with measurement functions (Z=F05). In addition, the message list contains the information required for handling the acyclic data traffic in the bus master. Table 3, page 30 lists a number of standard versions of communication-capable 3WN6 circuit-breakers (3pole) and their order numbers. The table can be used to look up the most economical solution for obtaining the required bus functions. Ordering details for the hardware and software which is required in addition to the circuit-breaker can be found in section 3.1.2, page 26. Note: The recommended versions are based on standard applications using 3-pole circuit-breakers.

All rights reserved. Version1.0 (05/98) Communication System Manual 3WN6 Circuit-Breakers The DP/3WN6 interface module must be correctly installed and connected (cf. user guide): The compact housing of the interface module is 70 mm wide and can simply be snapped onto a 35 mm DIN rail (the interface module must not be mounted directly above the 3WN6 arcing space, unless suitable covers have been fitted). The devices can be mounted side by side. The earth connection of the interface module (shield signal for electronic circuit) is made using an earth wire (2.5 mm2) and an earth terminal (order no. 8WA1001-1PF00) which is mounted on the DIN rail immediately next to the interface module. The cable screen of the 3WN6-DP/3WN6 connecting cable must also be earthed between the interface module and 3WN6, e.g. by connecting it to the DIN rail, in order to comply with interference emission standard EN 55022:1994, limit class A. The standard length of connecting cable 3WN6-DP/3WN6 between the 3WN6 circuit-breaker and the DP/3WN6 interface module is 3 m. Please refer to page 89 for detailed information on the DP/3WN6 interface (technical data, design, screening). Step 3: Connect DP/3WN6 to PROFIBUS-DP 12 Now you can wire connector 6ES7... (up to 12 Mbaud) to the PROFIBUS-DP cable (cf. connector user guide). Then plug the wired connector into the "PROFIBUS-DP" socket on the interface module. Step 4: Connect DP/3WN6 interface module to 3WN6 circuit-breaker Connection of 3WN6-DP/3WN6 connecting cable: This cable is supplied with the interface and is plugged into the 3WN6-DP/3WN6 adapter (9-pin SUB-D socket), which is fitted on the circuitbreaker at the factory, and into the "DP/3WN6" (9-pin SUB-D) socket on the front of the interface module. Note: All communication-capable circuit-breakers (fixed-mounted), and all communication-capable guide frames (for draw-out circuit-breakers) are fitted with a 3WN6-DP/3WN6 adapter at the factory. This 3WN6 adapter can also be ordered as a spare part using the following order numbers: - Adapter 3WN6-DP/3WN6 (0.4 m) for 3WN6 fixed-mounted circuit-breaker, comprising one SUB-D socket and free cable ends, and including mounting materials. Order number: 3WX3645-3JA00 - Adapter 3WN6-DP/3WN6 (0.4 m) for 3WN6 draw-out circuit-breaker, comprising one SUB-D socket and free cable ends, and including microswitch (circuit-breaker detection signaling switch) and mounting materials. Order number: 3WX3645-3JB00 12 This assumes that conventional copper conductors are used for PROFIBUS-DP. If fiber optic conductors are used, converters from fiber optic to copper conductors must be fitted. Version 1.0 (05/98) Copyright Siemens AG 1998. All rights reserved. 33 Communication System Manual Step 5: 3WN6 Circuit-Breakers Connect DP/3WN6 interface module to voltage supply Connect the 24 V DC voltage supply (DIN 19240) to the interface module: The interface module is fitted with a 4-pole screw terminal to facilitate the through connection of the 24 V supply. Note: In order to switch the 3WN6 circuit-breaker ON and OFF via PROFIBUS-DP, a 24 V DC supply must be connected to auxiliary plug X400.6 (cf. Fig. 5, page 32 and Fig. 6, page 32 in Step 2). For all other functions (monitoring, remote parameterization), the 24 V DC supply to the interface module is sufficient for supplying the communication electronics of the circuit-breaker. Step 6: Bus configuration If SIMATIC S5 is the bus master, the bus can be configured quickly and easily using either a PC or a SIMATIC programming device (PG) in conjunction with the COM-PROFIBUS or COM 5431 programs. In the case of other bus masters, the appropriate devices and/or supplier-specific tools must be used. The object of bus configuration is to define the 3WN6 device data, the 3WN6 bus address and the 3WN6 data area (I/O area) in the bus master. The 3WN6 device data can be read into the master in the form of type or GSD files. The following list outlines which file is required for which master: File allocation list:13 si8032td.200: si8032ad.200: siem8032.gsd: Step 7: Type file (German) "COM-PROFIBUS" tool Standard scope for Siemens master (S5-IM308B) Type file (German) "COM-PROFIBUS" tool Extended standard scope for Siemens master (S5-IM308C and S7) GSD file (device data) Standard scope for standard DP master Set bus address on DP/3WN6 interface module The bus address defined for 3WN6 in Step 6 can be set on the front panel of the DP/3WN6 interface module by means of 2 rotary switches (range 00 - 99). The rotary switch on the left (x10) sets the tens and the rotary switch on the right (x1) sets the units for the address. The baud rate cannot be set on the interface. It is automatically adjusted in line with the baud rate of the bus master (e.g. SIMATIC S5).14 Note: The communication connection to the circuit-breaker is automatically set up when the DP/3WN6 interface module is connected to the voltage supply. This power supply also activates the circuit-breaker overcurrent release (in the case of draw-out circuit-breakers in the connected and test positions). This permits the functionality of the slave "3WN6 circuit-breaker" to be checked and guaranteed. In the case of draw-out circuit-breakers in the disconnected position, the circuit-breaker state is detected using a separate microswitch (circuit-breaker detection signaling switch S20) in the guide frame. This is then signaled to the operational DP/3WN6 interface (see also DP/3WN6 user guide) in the form of a diagnostic message. Communication with the 3WN6 via the bus is not possible in this case. The presence of the circuit-breaker is merely checked. 13 14 34 The type and GSD files are also available under the following modem number: 0911-737972 The maximum possible baud rate corresponds to the maximum baud rate of the slowest field device.

Version1.0 (05/98) Communication System Manual Step 8: 3WN6 Circuit-Breakers Programming of bus master and data visualization The last step is to provide software for the bus master which enables it to communicate with the circuit-breaker. The cyclic data of 3WN6 (cf. section 3.2, page 28) can be read and written directly in the cyclic part of the defined I/O area (bytes 9 - 12) of the bus master (see Step 6). Acyclic data (cf. page 37 ff.) are transferred as the result of a message request in the acyclic part of the I/O area (bytes 1 - 8), which issues the appropriate command to 3WN6. The 3WN6 message requests are listed in full and explained on pages 37 ff. In the specific case of SIMATIC S5 or S7, a standard software block is available for acyclic communication. This software can be adapted to the user-specific information and control requirements and automatically manages the acyclic data traffic between the 3WN6 and the SIMATIC S5/S7. Please refer to the section entitled "Description of software block required for utilizing communication functions with SIMATIC S5 and S7" for a detailed description of this SIMATIC S5/S7 software block. The example given for SIMATIC S5/S7 can also be used as the basis for the programming other PROFIBUS-DP bus masters. The data in the master are now available for use by the customer. Some form of visualization with a user-friendly interface is generally implemented. The following standard programs are available to the customer for this purpose: * The Win3WN615 software provides the user with the full functionality of the 3WN6 circuitbreaker, i.e. start-up, operation and monitoring, at an attractive price: * * * * Data exchange with release types D, E/F, H, J/K, N, P Capable of running under Windows 95 or Windows NT 4.0 Configurations: SIMATIC S5, S7 or PROFIBUS-DP compatible PC as master Win3WN6 communicates with the circuit-breaker either via the RS-232 interface on the release (instead of the handheld operator panel) or via PROFIBUS-DP (with SIMATIC S5, S7 or a PC as bus master) * Overview of circuit-breaker state, "Tripped" signals (see screenshot) * Switching actions (password-protected) * Overview of operational data (e.g. phase currents) * Simple setting of protection parameters (password-protected) Example of Win3WN6 screenshot Most important advantage of Win3WN6: fast and economical use of circuit-breaker functions and convenient setting of protection parameters via the bus or via a local laptop connection. 15 Shipping of Win3WN6 software starts in 07/98.

All rights reserved. 35 Communication System Manual 3WN6 Circuit-Breakers Note: The software block for SIMATIC S5, S7 described above is included in the scope of supply of Win3WN6. * The new "SICAM LCC"16 software makes system visualization possible for low-voltage circuit-breakers 3VF, 3WN6, 3WN1, 3WS1 and the SIMOCODE-DP motor protection and control device. It complements the Win3WN6 software, as it puts the system in the foreground. SICAM LCC permits the user to create a standard visualization interface on which he can view all the important information about the system devices on PROFIBUS-DP The software makes this procedure simple, fast and economical for the user. Customer-specific expansions of this standard visualization can be implemented at any time using WinCC standard software. SICAM LCC is used for small to medium-sized systems. Software features: * Capable of running under Windows 95 or Windows NT 4.0 * Configurations: SIMATIC S5, S7 or PROFIBUS-DP compatible PC as master * Simply structured system overview (see diagram) * Detailed device displays with most important information * Calls for other device software (Win3WN6, Win-SIMOCODE) * Setting of device parameters (via Win3WN6, Win-SIMOCODE) * Measured value processing (Display of minimum, maximum, average etc.) * Event lists * Alarm lists * Printing, logging Example of SICAM LCC screenshot Once you have completed Step 8, the 3WN6 circuit-breaker is connected to the PROFIBUS-DP communication system. No further steps are generally required. 16 Shipping of SICAM LCC starts in 10/98. 36 Copyright Siemens AG 1998. All rights reserved. Version1.0 (05/98) Communication System Manual 3WN6 Circuit-Breakers 3.4 Displaying the data in the 3WN6 circuit-breaker 3.4.1 Addressing the 3WN6 functions on PROFIBUS-DP: In order to guarantee optimum data transfer times, the large volume of 3WN6 input and output data is divided into two transfer modes on PROFIBUS-DP (see Fig. 7, page 37): - Cyclic transfer and - Acyclic transfer 1 8 8 bytes of acyclic data 9 12 4 bytes of cyclic data Fig. 7: 12-byte I/O channel for 3WN6 Cyclic data are automatically transferred at regular intervals between the 3WN6 circuit-breaker and the PLC. Acyclic 3WN6 data/functions, on the other hand, must be transferred/executed on PROFIBUS-DP when required by means of a message request. A message request is defined in the first 8 bytes (or octets) of the PLC I/O area. These message requests initiate execution of the various functions of the 3WN6 circuit-breaker. The structure of acyclic messages is illustrated in Fig. 8 on page 37. 1 and 2 Parameter identifier 3 4 Parameter subindex Byte (octet) 5 (= OS1) 6 (= OS2) 7 (= OS3) 8 (= OS4) Parameter value (integer data value) Fig. 8: (Acyclic) message requests The bytes (octets) relevant for the unique identification of the message request (= message address) are shown on pages 39 - 51. The bytes (octets) shown in Fig. 2 are delimited by commas (format: bytes 1 and 2, byte 3, byte 4, byte 5, byte 6, byte 7, byte 8). Only the relevant bytes are shown, e.g. reading the rated current of the circuit-breaker uses bytes (octets) 1 to 6 (message address = 500, 4, 0, 0, 0). Detailed examples of message requests can be found on page 54, where you will also find a description of the request identifier, which must be used in addition to the message address in order to differentiate between read and write requests (request identifier + message address = complete message request).

"Fault signals" can also be individually deactivated (by setting message numbers 1:101 to 1:106 to 0). 46) If bit OS1:0 is set, an earth fault is registered in the "group fault signal" and a circuit-breaker trip is generated if an earth fault occurs.

Similarly, the "group warning signal" is set (= 1) of one bit of "warning signals" (message 1:3, Seite 44) is set and "group fault signal" is set if one bit of "Tripped signals" (message 1:2, page 43) is set. An additional option for releases N and P when used in conjunction with the communication module with measurement functions (Z=F05) is to apply the "fault signals" (message 1:8, Page 50) to either the "group warning signal" (for OS1:2 = 0) or the "group fault signal" (for OS1:2 = 1) by means of "additional functions 1" (message 1:121, Page 50). 52) Acknowledgement either by means of "Clear" button on the release unit or by means of bit 8 of the circuit-breaker output data. The acknowledgement generates a reset of the group fault signal and of all "Tripped" signals for which the trip cause is no longer present. Version 1.0 (05/98) Copyright Siemens AG 1998. All rights reserved. 53 Communication System Manual 3WN6 Circuit-Breakers 3.4.4 Examples of (acyclic) message requests: 1 and 2 Parameter identifier 3 4 Parameter subindex Byte (Octet) 5 (= OS1) 6 (= OS2) 7 (= OS3) 8 (= OS4) Parameter value (integer data value) Fig. 10: (Acyclic) message address Example 1: Message request: Write a parameterizable value The "z" release setting current is to be set to a value of 25000 A. The message address is therefore 782, 5, 0, 22, 0 in accordance with page 48. Bytes (= octets) 1 and 2 must also contain the request identifier for write and parameter number 782. The detailed structure of octets 1 and 2 can be seen in Fig. 11, page 54. Parameter identifier Byte (octet) 1 15 14 13 12 Request identifier Example 1: 0 0 1 1 11 - 10 - 0 Byte (octet) 2 Bit number 9 8 7 6 5 4 3 Parameter number 1 1 0 0 0 0 1 2 1 0 1 1 0 Fig. 11: Structure of parameter identifier (bytes 1 and 2) The request identifier for read is "1", for write "3": The request identifier must be entered in bits 15 12 of byte 1 as illustrated in Fig. 11, page 54, in this case a "1" in bits 13 and 12. Bits 14 and 15 both equal 0. The parameter number must then be entered in bits 0 - 10, in the above example the binary value "01100001110". Similarly the binary values "00000101" (= 5), "00000000" (= 0), "00010110" (= 22) and "00000000" (= 0) must be entered in bytes 3, 4, 5 and 6 respectively. Finally, the binary code for 25000 (the setting current), i.e. "0110000111101000", must be written in bytes 7 and 8. Example 2: Message request: Read a read-write value Message address 782, 5, 0, 22, 0, is also used to read the "z" release setting current. The same values as in example 1 are written in bytes 1 to 6 here (with the exception of the request identifier). Because this is a read request, the request identifier = 1 and bits 15 to 12 contain the binary value "1" (0001). No entries are necessary in bytes 7 and 8. These bytes will be used to store the read value of the "z" release setting current. Example 3: Message request: Read a read-only value The procedure for reading read-only values (e.g. operational data) is the same as for read-write values, i.e. the request identifier and the listed message address are written to bytes 1, 2, ... of the PLC I/O area of 3WN6. If, for example, the circuit-breaker state (T-Nr. 1:1) is to be read, then the request identifier must be set to 1 (byte 1), the value "741" must be entered in bytes 1 and 2, the value "1" in byte 3 and the value "0" in byte 4. These values must be entered in binary code. The read value for circuit-breaker state is stored in bytes 5, 6, 7 and 8. Important notice: Only the cyclic data from the 3WN6 circuit-breaker (see pages 52 ff.) are regularly updated in the PLC I/O area. Acyclic data are read on request only. If, for example, byte (octet) 9 of the I/O area contains a "group fault signal" (bit 8 = 1), then the "Tripped signals" (and possibly the "fault signals" in the case of releases N and P with Z=F05) will need to be read for a more detailed fault analysis. 54 Copyright Siemens AG 1998.

Version 1.0 (05/98) Communication System Manual 3WN6 Circuit-Breakers 3.4.5 Time response of data traffic The time response of 3WN6 data traffic via PROFIBUS-DP is outlined in detail on the following pages with reference to the different data which are transferred (acyclic, cyclic, circuit-breaker key data, circuit-breaker functions ...). Please note that the PROFIBUS-DP cycle times which are implicit in the specified time values generally depend on the number of slaves, i.e. values can vary. This simple rule of thumb generally applies: To read approx. 0.5 seconds, to write approx. 1 second, to write and check approx. 2 seconds. The various items of data present in 3WN6 are updated at different intervals depending on their importance. Time response of acyclic data traffic: Message group 0 T-Nr.

All rights reserved. Version 1.0 (02/98) Communication System Manual 3WN6 Circuit-Breakers 3.5.3 STEP 5 program The function and data blocks required for utilizing the full scope of communication are supplied on diskette. An example illustrates how these blocks are integrated in an existing S5 program and how they are adapted in line with local conditions. Attention: The following versions are required if the program is to function properly: * 3WN6 interface module: old hardware version (PROFIBUS outgoing circuit on base) 2, new hardware version (PROFIBUS outgoing circuit on top) 1 * Type file/GSD file: V1.1 3.5.3.1 Brief outline of software block tasks This program automates the message traffic from the PLC (via DP master) to the circuit-breaker (via interface module). A request can be entered in the list of read requests to be processed by setting only one bit. The requests in this list are processed consecutively and are inserted in the acyclic part of the message. The handling of message numbers and associated parameter subindices is no longer necessary. The software block takes care of all this. This also applies to the reading of circuit-breaker data, which are read in once by setting the relevant bits. The parameterization of new values in the circuit-breaker is performed by simply entering the new values in a specific position. The software block handles the complex management of message numbers etc. in all three tasks and the user now only needs to set bits to enable requests for read operations or to enter new values in order to perform write operations. 3.5.3.2 Preparing to use the software block The user must load the required function blocks in line with the PROFIBUS-DP master he is using, e.g. FB192 for IM 308-C (Attention: CPU-dependent block!) or the data handling blocks "SYNC", "SEND", "RECEIVE" and "CONTROL" for CP5431. Data integrity over the entire length must be guaranteed independently of the CPU and the DP master. No special access technology is required here when CP5431 is used. However, prior to calling FB10, DHB SEND must be called up followed by DHB RECEIVE, in order to the define the trigger points for data integrity. Synchronization must also be performed using DHB SYNC on start-up. 3.5.3.3 General information and adaptations The user can adapt the software as required. The software kernel comprises 6 function blocks (FBs): * * * * * * FB10 FB81 FB82 FB100 FB101 FB102 Name: ROOT3WN6 Name: REC Name: SEND Name: LESE WCC Name: SCHREIBEN Name: LESEN Request processing and calls for required FBs Reads response to transferred T-Nr. Writes parameter for transferred T-Nr. Defines new T-Nr. for cyclic reading of operational data Defines new T-Nr. for writing of operational data Defines new T-Nr. for reading circuit-breaker data Request processing (FB10) defines the type of the next request, e.g. whether operational data are to be read or written. FB10 then ensures that the next messages of this type are detected and transferred to the 3WN6 interface. Values which are read are stored in a data block and values to be written are fetched from a data block and transferred to the circuit-breaker. If neither writing (parameterization) nor reading of circuit-breaker key data (message group 0) is active, the data which are read out (in DBG1) are copied into DBSZ and DBAT, in order to permit "parameterization from below" (via the RS-232 interface on the 3WN6 release). Version 1.0 (05/98) Copyright Siemens AG 1998. All rights reserved. 63 Communication System Manual 3WN6 Circuit-Breakers The FBs SEND and REC are assigned to data blocks when they are called. DB80 contains the message headers for message group 0 and DB81 contains the message headers for message group 1. These blocks are structured such that the basic data word (DW no.) can be calculated as follows for a message number (T-Nr.): DW no. = 2 x T-Nr. The parameter identifier is stored in the basic data word. The following data word contains the parameter subindex. The data to be sent and the data to be received (to/from 3WN6) are also stored in data blocks (in the example: DB230 and DB220). Block call structure of example: FB10 FB81 DB80 FB82 DB81 DB210 OB1 FB100 DB220 FB101 FB102 DB230 DB240 Contents and function of data blocks: DB80 DB header, assignment of parameter identifier for message group 0 DB81 DB header, assignment of parameter identifier for message group 1 DB210 (DBG0) Storage locations for read circuit-breaker data DB220 (DBG1) Storage locations for read operational data of circuit-breaker (actual values!)

All rights reserved. Version 1.0 (02/98) Communication System Manual 3WN6 Circuit-Breakers 3.5.3.3.1 Adaptation to master module Adaptation to the DP master module is performed in the start-up OBs and in cycle OB1. If CP5431 is used as master, it must be synchronized on start-up. It also requires one cyclical trigger point for input and one for output in order to exchange data. The data handling blocks are responsible for these tasks and have been integrated in CP3WN6ST.S5D in exemplary fashion. Please ensure that the correct data handling blocks are used for the implemented CPU. Trigger point FBs FB50 and FB51, the FBs for start-up synchronization (FB52), and FB 53 for diagnostics must also be supplied with the correct call parameter in the example program, i.e. S5 = 115 (for S5 115) or 135 (for S5 135/155). This makes it possible for a single example program to run on all S5 CPUs. The slaves must be defined as cycle-synchronous in COM5431 for the DP update, in order to ensure data integrity. With IM308C as master, only the CPU-specific FB192 needs to be loaded. The following data handling blocks are required for the example program with the CP as master: 115: FB244, FB245, FB247, FB249 all CPU-dependent 135/155: FB120, FB121, FB123, FB125 all CPU-dependent Note: If CP5431 is used as DP master, access to the I/O modules is only possible after a hardware reset (voltage OFF). Otherwise a time-out/no acknowledgement signal is output. 3.5.3.3.2 Other adaptations The printed program listing is an example in which the settings can be adapted to suit individual requirements. Please read Description of examples for further information. Please note that only one send or receive request can ever be initiated at any one time for the same 3WN6 circuit-breaker. If several circuit-breakers are in use, FB10 must be called once for each circuit-breaker and supplied with the correct call parameters. The I/O addresses, DBs and timers must only ever be used once. The following address space is available for I/O addresses: IM308C: I/O 128 to 255 CP5431: I/O 0 to 255 in the I/O area with linear addressing in each case. It is necessary to keep within this area in order to ensure data integrity. 3.5.3.3.3 Diagnostics If diagnostics are required (e.g. for Win3WN6), an insertion must be made in the DBAT relative to the DP master as of DW200. In the case of IM308C, this is achieved by means of an FB192 call addressed to the slave. Both the DP address of the slave and the DBAT no. in which the diagnostic data are to be stored must be specified (see example IM308CST.S5D). The diagnostics for CP5431 vary depending on the CP. The CP is first scanned to check for the presence of diagnostic data (can be seen from FB53 in example CP3WN6ST.S5D). If such data are present, slave diagnostics are requested by means of a SEND request. The PROFIBUS slave address must be known, however. This must be entered in DR198 of DBAT. The diagnostic message can then be read out of the returned data in DW203 of DBAT. It is also possible to detect from DW200 whether the PROFIBUS connection to the interface module of the circuit-breaker is in order. A definitive statement can be made regarding the correct connection to 3WN6 based on an OR operation on the channel-specific diagnostics (DW203) and the "Station_Not_Existent" bit (PROFIBUS standard in station status 1 in DW200). If diagnostic messages are to be fetched from several 3WN6s, the S5 with CP5431 as master must ensure that only one diagnostic message is ever sent to a slave at a time. Diagnostic messages for another 3WN6 can only be requested when the diagnostic response has been received from the previous circuit-breaker. This can be achieved by means of a counting distributor, for example. Version 1.0 (05/98) Copyright Siemens AG 1998. All rights reserved. 65 Communication System Manual 3WN6 Circuit-Breakers 3.5.3.4 Data blocks (DBs) The send and/or receive data block and a message header data block must be configured by the user unless the DBs supplied with the example are to be used. The maximum used length of such a data block is 261 bytes, i.e. the data block must be configured up to and including data word 255. The length is not checked. The block-type structure is as follows (see also Program listing): Data word 0: Symbol for value to be processed acc. to profile (parameter identifier) - T-Nr. 0 Data word 1: Symbol as sub-item for value to be processed (parameter subindex) - T-Nr. 0 Data word 2: Symbol for value to be processed acc. to profile (parameter identifier) - T-Nr. 1 Data word 3: Symbol as sub-item for value to be processed (parameter subindex) - T-Nr. 1 Data word 4: Symbol for value to be processed acc. to profile (parameter identifier) - T-Nr. 2 Data word 5: Symbol as sub-item for value to be processed (parameter subindex) - T-Nr. 2 etc. The user himself is responsible for entering the correct values in the data block, as well as for creating a data block of the correct length. The user must configure the DB up to at least data word 2x+1 (where x = maximum occurring T-Nr.). 66 Copyright Siemens AG 1998. All rights reserved. Version 1.0 (02/98) Communication System Manual 3WN6 Circuit-Breakers 3.5.3.4.1 Position of cyclic part of message Because applications such as WinCC can only access SIMATIC S5 data blocks via FDL link, for example, the cyclic part of the message must be inserted in the DB. The cyclic input bytes are stored in DW96 and 97 of DBAT and the output bytes in DW98 and 99. These can be used to poll the cyclic messages and to switch the circuit-breaker on and off. The program resets the bits for switching on/off after 250 ms. 3.5.3.4.2 Enabling and priority assignment of acyclic requests for operational data to be read cyclically 100: 101: 102: 103: 104: 105: 106: 107: 108: 109: 110: 111: 112: 113: 114: 115: 116: 117: 118: 119: 120: 121: 122: 123: 124: 125: 126: 127: 128: 129: 130: 131: KM = 00000000 00011110; KM = 00000000 00000000; KM = 00000000 00000000; KM = 00000000 00000000; KM = 00000000 00000000; KM = 00000000 00000000; KM = 00000000 00000000; KM = 00000000 00000000; KM = 11110100 10011110; KM = 11000000 00000000; KM = 00000000 00000000; KM = 00000000 00000000; KM = 00000000 00000000; KM = 00000000 00000000; KM = 00000000 00000000; KM = 00000000 00000000; KM = 00000000 00000000; KM = 00100111 10100001; KM = 11000000 01101111; KM = 11110000 00000000; KM = 00000000 00000000; KM = 00000000 00000000; KM = 00000000 00000001; KM = 10000000 00000000; KM = 00000000 00000000; KM = 00000000 00000000; KM = 00000000 00000000; KM = 00000000 00000000; KM = 11100001 10000000; KM = 01111100 00000100; KM = 00000111 11111000; KM = 00000000 00000000; Version 1.0 (05/98) Screen: Read request T-Nr. 0 to 15 Read: T-Nr. 16 to 31 T-Nr. 32 to 47 T-Nr. 48 to 63 T-Nr. 64 to 79 T-Nr. 80 to 95 T-Nr. 96 to 111 T-Nr. 112 to 127 Screen: Assignment to priority 1 T-Nr. 0 to 15 Read: T-Nr. 16 to 31 T-Nr. 32 to 47 T-Nr. 48 to 63 T-Nr. 64 to 79 T-Nr. 80 to 95 T-Nr. 96 to 111 T-Nr. 112 to 127 Screen: Assignment to priority 2 T-Nr. 0 to 15 Read: T-Nr. 16 to 31 T-Nr. 32 to 47 T-Nr. 48 to 63 T-Nr. 64 to 79 T-Nr. 80 to 95 T-Nr. 96 to 111 T-Nr. 112 to 127 Screen: Assignment to priority 3 T-Nr. 0 to 15 Read: T-Nr. 16 to 31 T-Nr. 32 to 47 T-Nr. 48 to 63 T-Nr. 64 to 79 T-Nr. 80 to 95 T-Nr. 96 to 111 T-Nr. 112 to 127 Copyright Siemens AG 1998. All rights reserved. 67 Communication System Manual 3WN6 Circuit-Breakers The lines are an extract from DB240 (DBAT, data block for request processing) designed to explain the enabling and priority assignment of read requests which are to be processed "cyclically". Messages are enabled from DW100 to DW107 by setting a "1". In the example given here, messages 11, 12, 13 and 14 are enabled in DW 100. The messages are classified according to priority in DW 108 to DW 131. Priorities have already been assigned but can be changed according to requirements. The message numbers increase from left to right within the DB, in the same way as for the enable. Priority assignment entails sending requests with a higher priority more frequently than messages with a lower priority. The enable and one priority assignment must be allocated in order to generate a valid message. In the example provided, this means that only requests 11 - 14 are enabled and these are assigned to priority 1 by default. This type of enabling permits the program to be adapted to a wide range of conditions, e.g. visualization with several windows which only ever display a small number of values. Only the required values need to be updated here, thus allowing for a considerable increase in performance. 3.5.3.4.3 Circuit-breaker parameterization (writing parameters) The data which the circuit-breaker is currently using as parameters are stored in DB240. The data to be transferred to the 3WN6 are stored in DB230. FB10 now checks on every call whether the data in DB230 and DB240 are consistent. If a discrepancy is detected, a bit for writing requests is set. The new values in DB230 are then transferred to 3WN6 and stored as old values in DB240. The request bit is reset. If a new value is to be parameterized, it must therefore be entered at the correct position in DB230. The position is calculated in the same way as for DB80 and DB81: DW no. = 2 x T-Nr.+1 Example: "z" release setting current, T-Nr. 65, tripping value 20 kA Enter 20000 in DW65*2+1 = DW131 of DB230 Special cases: The parameters for additional functions 111/112 must be entered as follows: 111: in DL222 of DBSZ 112: in DR225 of DBSZ The differences occur as these are the only parameterization messages to parameterize two words. All others parameterize only the second word. Attention: Because parameter Ir can be assigned using either the cyclic or the acyclic part of the message, only one of these options is supported in order to avoid parameter inconsistencies. The parameter for Ir can therefore only be transferred using the acyclic message and an entry in DW99 of DBAT (which would trigger cyclical parameterization) does not change the parameter in the circuitbreaker. 68 Copyright Siemens AG 1998. All rights reserved. Version 1.0 (02/98) Communication System Manual 3WN6 Circuit-Breakers 3.5.3.4.4 Reading circuit-breaker data Circuit-breaker key data are read by setting the relevant bits in DW0 and DW1 of DBAT (DB240 in this example). The data which are read out are stored in DB80. As the circuit-breaker data do not change during operation, a single call of the messages is sufficient, e.g. by setting the bits in the relevant OBs on start-up/restart. Example: Read all circuit-breaker data. ADB 240 LKM 01111100 00011111 TDW 0 LKM 10000100 00000000 TDW 1 All the bits in DW0 and DW1 can also be set. If a request does not exist, it is canceled after a watchdog time of 1 s. 3.5.3.5 Description of examples FB REC is called and parameters are passed to it in order to read 3WN6 data. FB SEND is used to write data to the 3WN6 interface module. Both blocks have a similar list of designators: T-DB An input word (MW206 in the example) containing the number of the data block in which the message headers are stored. Q-DB/Z-DB An input word (MW208 in the example) containing the number of the data block in which the parameter values are stored/are to be stored. Q-DW/Z-DW An input word (DW254 in the example) which can be used to specify an offset for the basic data word in the data block for parameters. STAT An input word for an auxiliary storage location which is needed in blocks FB SEND and FB REC. This auxiliary storage location contains the value 0 when the request has been processed, the value 2 during processing and any other value - the value 1 in the example - in order to indicate a new request. T-NR An input byte to specify a message number to be processed (reference to data word to be processed in T-DB and Q-DB/Z-DB - DW in T-DB = 2 x T-NR and following DW; DW in Q-DB/Z-DB = 2 x T-NR + value in Q-DW/Z-DW and following DW) (DL251 in the example). EW0 Input word (MW220 in the example) in which the first two byes of the response from 3WN6 are stored (parameter identifier). EW1 Input word (MW222 in the example) in which bytes three and four of the response from 3WN6 are stored (parameter subindex). EW2 Input word (MW224 in the example) in which bytes five and six of the response from 3WN6 are stored (size and conversion index for requested value). EW3 Input word (MW226 in the example) in which bytes seven and eight of the response from 3WN6 are stored (requested value). AW0 Output word (MW230 in the example) in which the first two byes to be sent to 3WN6 are stored (parameter identifier). AW1 Output word (MW232 in the example) in which bytes three and four to be sent to 3WN6 are stored (parameter subindex). AW2 Output word (MW234 in the example) in which bytes five and six to be sent to 3WN6 are stored (size and conversion index for value to be transferred). AW3 Output word (MW236 in the example) in which bytes seven and eight to be sent to 3WN6 are stored (value to be transferred). Version 1.0 (05/98) Copyright Siemens AG 1998.

Data blocks DBG1 (DB220) and DBSZ (DB230) are used as data storage locations for the read and write requests to the circuit-breaker in the example. The size and conversion index are stored here, as is the value for a message number. The offset is set to 0. The data read from 3WN6 are stored in DB220 and the write data are stored in DB230. The slave data for this example are selected as follows: * Slave address 8 * Inputs in S5 at addresses P144 to P155 * Outputs in S5 at addresses P156 to P167 70 Copyright Siemens AG 1998.

TIM1 The timers can be specified externally so that the block can be used universally. TIM2 See above 3.5.3.7 Procedure for creating your own project 1. The data blocks must contain exactly the same structure and contents as in the example provided. We therefore recommend that you copy them out of this project. Otherwise problems may occur. 2. The following blocks must be copied into the project: FB10, FB81, FB82, FB100, FB101, FB102 3. FB10 and its parameters must be called from the cyclic program (e.g. OB1). 4. An FB10 call must be assigned to each circuit-breaker. The parameters (DBs, timer, I/O area) must not overlap. 5. Adaptations to the DP master may be necessary, e.g. CP5431 and diagnostics. Note: Only flags over the 200 area (scratch flag area) are used in software block FB10. These are reinitialized on every call and can therefore also be used throughout the entire program provided they are always reinitialized. This means that the entire flag area can also be used by the user program. Version 1.0 (05/98) Copyright Siemens AG 1998. All rights reserved. 77 Communication System Manual 3WN6 Circuit-Breakers 3.5.3.8 Description of visualization with software block We shall demonstrate the use of the software block with reference to an example. Actual phase currents L1, L2 and L3 are to be displayed in a visualization window (e.g. WinCC). The actual state of the circuit-breaker should also be displayed. It should also be possible to display and set new parameters for the "a" release in this window (T-Nr. 61). 3WN6 visualization 315 Phase current L1 319 Phase current L2 325 Phase current L3 "a" release 980 SET Circuit-breaker ON Circuit-breaker OFF Load shedding Ready to close Switch circuit-breaker ON ON Storage spring charged Switch circuit-breaker OFF OFF These 3 requests must be entered in the list of cyclic messages for the actual phase current to be displayed in the boxes. This is achieved by setting the bits in DW100 of DBAT (only enable messages 11 - 13), see 3.5.3.4.2. The actual currents can then be copied into the window from data words DW23, 25 and 27 of DBG1. The circuit-breaker states are transferred with every message in the cyclic part and can be obtained from data words DW96 and 97 of DBAT (DW96 corresponds to octets 9 and 10, DW97 to octets 11 and 12). The ON and OFF buttons can be used to set 3WN6 to the required state. Bit 1 (for OFF) or bit 0 (for ON) of octet 10 must be set for this purpose. The bit is automatically reset. If octet 10 cannot be reached directly for visualization, these bits can also be set in DW98 of DBAT. They are written out at the end of the cycle. A value is to be parameterized in accordance with message 1:61. If the actual parameterized value is to appear in the box, the corresponding bit must be set in DW103 of DBAT (as was the case with the current values). This value is then updated cyclically. The value in the box must be copied from DW123 of DBG1. To parameterize a new value, enter the value in the box and press the SET button. The visualization software then copies this value to the correct location of DBSZ, i.e. to DW123 (= TNr. *2 +1). The block then detects this new value and parameterizes it in the circuit-breaker. When the procedure is complete, the actual parameterized value is again displayed in the box until such time as 3WN6 has verified and returned the new value. Note: Win3WN6 and SICAM LCC are available (see page 35) for standard visualization of 3WN6 circuit-breaker information. 78 Copyright Siemens AG 1998. All rights reserved. Version 1.0 (02/98) Communication System Manual 3WN6 Circuit-Breakers There is also another way of changing parameters in the 3WN6 circuit-breaker, i.e. by connecting suitable devices to the serial interface at the front of the display unit. It is important that the bits for cyclic reading of the displayed values are set in order that the S5 software and the visualization can detect these changes (already configured in this example). This guarantees data consistency between the circuit-breaker and the S5 data management. Changes should only be made via the serial interface when the corresponding read request bit (as of DW100 in DBAT) is set. If several windows are used for displaying the circuit-breaker, only the actually displayed values need to be updated cyclically. Otherwise the performance is compromised. 3.5.4 STEP 7 program The kernel of the software block is the same as for S5. However, some changes are required for S7 due to the conversion. 1. The data words in the data blocks of S5 must be multiplied by 2 for S7. 2. The initial I/O addresses do not need to be supplied for the FC10 call. It is necessary to differentiate between the CPU and the CP as DP master, in order to guarantee data integrity in S7. In the case of a CPU as master, CALL SFC14 must be performed prior to CALL FC 10. This copies the valid input data to the flag area (12 bytes). This must be followed by CALL SFC15, which copies the flag data (12 bytes) to the output area (see S7 example). In the case of a CP as master, both calls are replaced by CALL "SEND" and CALL "RECEIVE", which have the same effect. Version 1.0 (05/98) Copyright Siemens AG 1998.

The connection of the 3WN1 and 3WS1 circuit-breakers to PROFIBUS-DP is implemented by means of the DP/3WN1, 3WS1 interface in conjunction with a digital I/O module (e.g. ET 200) which has been customized to suit the application. The information available on the overcurrent release is transferred to the bus via the interface module and the circuit-breaker information via the I/O module.

Version 1.0 (08/98) Communication System Manual Step 2: 3WN1, 3WS1 Circuit-Breakers Check the system requirements The second step involves checking the following three requirements for connecting 3WN1/3WS1 to PROFIBUS-DP: * The communication-capable 3WN1/3WS1 circuit-breaker must be installed and wired in accordance with the user guide (included in scope of supply of circuit-breaker). Note ! Circuit-breaker position A draw-out circuit-breaker must be in the test position for testing and in the connected position for normal operation. When wiring, please ensure that the jumper arrangements on the auxiliary connectors are correct (cf. Fig. 15, page 91 and Fig. 15, page 92 in the 3WN1/3WS1 user guide) * The PROFIBUS-DP master must be present and operational. * The 3RK1002 interface module must be correctly installed and connected (section 4.5.2, page 90). * The compact housing of the 3RK1002 interface module is 70 mm wide and can simply be snapped onto a 35 mm DIN rail. The devices can be mounted side by side. Note ! Installation procedure The interface module must not be mounted directly above the arcing space of the circuit-breaker, unless suitable covers have been fitted. * The earth connection of the interface module (shield signal for electronic circuit) is made using a flexible earth wire (1.5 mm2) and an earth terminal (order no. 8WA1001-1PF00, for example) which is mounted on the DIN rail immediately next to the interface module. * The 9-pin SUB-D socket on the 3WN1/3WS1 circuit-breaker which is used for the connecting cable between the circuit-breaker and the interface module must be earthed using a flexible 2 earth wire (2.5 mm ). -The standard length of connecting cable 3WN1/3WS1-3RK1002 between the 3WN1/3WS1 circuitbreaker and the 3RK1002 interface module is 3 m.

Version 1.0 (08/98) Communication System Manual Step 4: 3WN1, 3WS1 Circuit-Breakers Connect 3RK1002 interface module to PROFIBUS-DP 58 Now you can wire the appropriate 6ES7... connector (up to 12 Mbaud) to the PROFIBUS-DP cable based on the baud rate required on the bus59 (cf. connector user guide). Then plug the wired connector into the "PROFIBUS-DP" socket on the interface module. (--> see also section 4.5.2.2.3, page 93) Step 5: Connect 3RK1002 interface module to 3WN1/3WS1 circuitbreaker Connection of 3WN1/3WS1 <--> 3RK1002 connecting cable: This cable is supplied with the interface and is plugged into the 3WN1, 3WS1/3RK1002 adapter (9-pin SUB-D socket), which is fitted on the circuit-breaker at the factory, and into the "3WN1, 3WS1" (9-pin SUB-D) socket on the front of the interface module. Note ! Installation procedure All communication-capable circuit-breakers (fixed-mounted) and all communication-capable guide frames (for draw-out circuit-breakers) are fitted with a "3WN1, 3WS1/3RK1002" adapter at the factory. This 3WN1, 3WS1 adapter can also be ordered as a spare part using the following order numbers: * Adapter "3WN1/3WS1/3RK1002" (0.4 m) for 3WN1/3WS1 fixed-mounted circuit-breakers, comprising one SUB-D socket and free cable ends, and including mounting materials. Order number: 3WX3145-3JA00 (--> see also section 4.5.2.2.2, page 92) Step 6: Connect 3RK1002 interface module to voltage supply Connect the 24 V DC voltage supply (DIN 19240) to the interface module: The interface module is fitted with a 4-pole screw terminal to facilitate the through connection of the 24 V supply. (--> see also section 4.5.2.2.4, page 94) 58) 59) This assumes that conventional copper conductors are used for PROFIBUS-DP.

Step 8: Set bus address on 3RK1002 interface module The bus address defined for 3WN in Step 7 can be set on the front panel of the 3RK1002 interface module by means of 2 rotary switches (range 00 - 99). (--> section 4.5.3.1.1, page 101) The rotary switch on the left (x10) sets the tens and the rotary switch on the right (x1) sets the units for the address. The baud rate cannot be set on the interface. It is automatically adjusted in line with the baud rate of the bus master (e.g. SIMATIC S5).61 High-performance software is available for the visualization and evaluation of the data transferred from 3VF (see page 35 ff. for description): "SICAM LCC" for the visualization of complete systems implementing circuit-breakers 3VF, 3WN6, 3WN1, 62 3WS1, and a SIMOCODE-DP motor protection and control device. An additional software block is required for 3WN1/WS1 visualization using SICAM LCC and SIMATIC. It makes the data on PROFIBUS available to the PC via an FDL link. Once you have completed Step 8, the 3WN1/3WS1 circuit-breaker is connected to the PROFIBUS-DP communication system. No further steps are required. 61 62 88 The maximum possible baud rate corresponds to the maximum baud rate of the slowest field device. Shipping of SICAM LCC starts in 10/98.

We recommend that you use a 3.5 mm screwdriver for tightening the screws. Permissible conductor cross-section: - Flexible conductor with end sleeve: - Solid conductor: Tightening torque: 1 x 0.25 ... 1.5 mm2 1 x 0.25 ... 1.5 mm2 0.5 ... 0.8 Nm b) Plug-type terminals are a combination of standard screw terminals and plug-in connections. The plug-in connection part is polarized and cannot be plugged in the wrong way. c) The 9-pin SUB-D connectors are secured with 2 x 4-40 UNC threads. We recommend that you use a 3.5 mm screwdriver for tightening the screws. Tightening torque: 0.2 ... 0.4 Nm 4.5.2.2.2 3WN1, 3WS1 communication interface This interface takes the form of 9-pin SUB-D connectors on the interface module and the 3WN1/3WS1 circuit-breaker. * Insert the plug on the supplied connecting cable into the 9-pin SUB-D socket labeled "3WN1, 3WS1". * Insert the other plug on the connecting cable into the 9-pin SUB-D socket on the circuit-breaker. * Tighten the retaining screws on the connectors using a screwdriver.

Please note that the "6ES5..." connectors are only suitable for baud rates up to a maximum of 1.5 Mbit/s. * Tighten the retaining screws on the connector using a screwdriver. * If the interface module is at the end or at the start of the PROFIBUS line, you must activate the integrated terminating resistor in the connector. To do this, slide the switch on the rear of the connector into the position labeled "on". * If the interface module is at the end or at the start of the PROFIBUS line, slide the switch into the position labeled "off". Fig. 17: "PROFIBUS-DP" communication interface on on off GND off A (inverted signal) 5V DC B (non-inverted signal) Shield Bus with fiber optic cables The PROFIBUS-DP interface can also be used for connecting fiber optic conductors with the help of an OLP (optical link plug), i.e. the interface supplies the current (max. 80 mA) required by the OLP. * The OLP order number is: 6GK1502-1AA00 * Plug the OLP into the interface labeled "PROFIBUS-DP". * Tighten the retaining screw on the OLP using a screwdriver. * Plug both fiber optic terminals into the designated sockets on the OLP. * Set the required baud rate on the OLP as specified in the OLP description. * There is no need for a terminating resistor in the case of fiber optic cables.

All rights reserved. 93 Communication System Manual 3WN1, 3WS1 Circuit-Breakers 4.5.2.2.4 Power supply The device is connected to the 24 V DC power supply by means of a 4-pole plug-type screw terminal. The 24 V DC voltage of the power supply unit may fluctuate between 20.4 V and 28.8 V as specified in DIN 19240. The 4-pole plug-type screw terminal makes a through connection of the 24 V supply to another device possible. Please note, however, that the supply voltage is looped through the device, i.e. the supply voltage to the other device is also interrupted when the screw terminal is disconnected. * Connect the supply voltage to the designated 4-pole plug-type screw terminal on the front panel of the device. Fig. 18: Power supply terminal 4.5.2.2.5 Screen bonding The interface module is fitted with two contact points for screen bonding. These are two electrically isolated screens in the device which must be connected to the equipotential bonding strip outside the module. This precaution ensures a greater immunity to interference as the "cable screen current", which can be anything up to a few amperes due to differences of potential of two slaves, is not discharged via the device. The first screen bonding point (= screen for internal filter connections) is located on the base of the interface module and is automatically connected when the module is mounted on the DIN rail. Note ! High levels of stress If the device is subject to high levels of mechanical or chemical stress, we recommend that a tinned DIN rail be used in order to ensure a good contact to the screen bonding.

All rights reserved. Version 1.0 (08/98) Communication System Manual 3WN1, 3WS1 Circuit-Breakers 4.5.2.3.1 General information on wiring arrangements a) In cubicles and not in cubicles It is useful to classify cables into the following cable groups and to install these groups separately in order to comply with EMC guidelines. Group A: * Screened bus and data cables (e.g. for PROFIBUS-DP, 3WN1, printers etc.) * Screened analog cables * Unscreened cables for DC voltages 60 V * Unscreened cables for AC voltages 25 V * Coaxial monitor cables Group B: * Unscreened cables for DC voltages 60 V and 400 V * Unscreened cables for AC voltages 24 V and 400 V Group C: * Unscreened cables for DC voltages > 400 V Group D: * SINEC H1 (Ethernet) cables You can use the table below to look up the conditions required for installing cables based on different group combinations. Table 13: Cable installation regulations for combinations of cable groups Group A Group B Group C Group D * Group A Group B Group C Group D * * * * Cables can be installed in the same bundles or cable ducts. Cables must be installed in separate bundles or cable ducts (no minimum clearance). Cables in cubicles must be installed in separate bundles or cable ducts. Cables not in cubicles but inside buildings must be installed in separate cable raceways with a minimum clearance of 10 cm. Cables must be installed in separate bundles or cable ducts with a minimum clearance of 50 cm. b) Outdoors Install cables which are not inside buildings on metal cable trays if possible. Make an electrical connection between the joints of the cable trays and earth the cable trays. Observe the usual lightning protection and earthing measures when installing cables outside buildings. General guidelines: * Lightning protection: If cables and wires required for the interface are to be installed outside buildings, measures must be implemented for internal and external lightning protection. Install cables outside buildings in either - metal conduits earthed at both ends or - concrete cable ducts with continuous reinforcement. Protect the signal cables from overvoltage by means of - varistors or - surge arresters filled with inert gases. Install these protective elements at the point where the cable enters the building. * Equipotential bonding: Ensure that there is sufficient equipotential bonding for the connected devices.

All rights reserved. 97 Communication System Manual 3WN1, 3WS1 Circuit-Breakers 4.5.2.3.2 Equipotential bonding Differences of potential can occur between separate system sections in the case of * PLCs and I/O modules connected via non-isolated links or * Cable screens contacted at both ends and earthed on different plant sections. Differences of potential can occur due to different power supply inputs, for example. These differences must be reduced by means of equipotential bonding conductors, in order to ensure the continuing operation of all the electronic components in the system. Please note the following items with regard to equipotential bonding: * The lower the impedance of the equipotential bonding conductor, the more effective the equipotential bonding. * If screened signal cables which are connected to the protective earth conductor at both ends are to be installed between the affected system sections, the impedance of the additionally installed equipotential bonding conductor must not be greater than 10 % of the screen impedance. * The cross-section of the equipotential bonding conductor must be large enough for the maximum compensating current. The following cross-sections have proved useful in practice: - 16 mm2 Cu for equipotential bonding conductors up to 200 m in length - 25 mm2 Cu for equipotential bonding conductors over 200 m in length * Use equipotential bonding conductors made of copper or galvanized steel. Make a large-area connection between them and the protective earth conductor and protect the equipotential bonding conductors from corrosion. The equipotential bonding conductor should be installed such that the areas enclosed between the equipotential bonding conductor and the signal cables are as small as possible. * 4.5.2.3.3 Cable screening Screening is a measure designed to reduce magnetic, electrical or electromagnetic interference fields. Interference currents on cable screens are discharged to earth via the conducting screen bus which is connected to the housing. A low-impedance connection to the protective earth conductor is especially important to ensure that these interference currents do not themselves become a source of interference. Only use cables with a braided screen if possible. The coverage density should be more than 80 %. Avoid cables with foil screens as the foil can very easily be damaged by tension and compression loads when fixing, the result being a reduction in the effectiveness of the screen. You should generally always connect cable screens at both ends. Only then is it possible to achieve good interference suppression in the higher frequency range. The screen should only be connected at one end in exceptional cases. This only attenuates lower frequencies, however. A single-ended screen connection can be an advantage in cases where * it is not possible to install an equipotential bonding conductor. * analog signals (a number of mV or mA) are transmitted. * foil screens (static screens) are used. Always use metal or metal-plated connectors in the case of serial link data cables. Fix the screen of the data cable to the connector casing. Do not connect the screen to PIN 1 of the connector! 98 Copyright Siemens AG 1998. All rights reserved. Version 1.0 (08/98) Communication System Manual Note ! 3WN1, 3WS1 Circuit-Breakers Differences of potential If there are differences of potential between the earthing points, compensating current can flow across the screen connected at both ends. Install an additional equipotential bonding conductor in this case. Please note the following items with regard to the screen: * * Use metal cable clamps for fixing the braided screens. There must be a good, large-area contact between the clamps and the screen. Connect the screen to a screen bus immediately after the cable enters the cubicle. Run the screen through as far as the module but do not connect it again! Fig. 21: Possible cable screen connections Screened data cables and unscreened power supply cables (< 60 V DC) are run through to the interface module and connected. All the cable screens must be earthed at both ends in order to comply with EMC limits. * * * The PROFIBUS-DP cable screen must be connected to the equipotential bonding strip as it enters the switchgear cubicle. The supplied screened 3WN1 connecting cable must be earthed on the shield terminal of the interface module using a flexible wire (as short as possible) with a cross-section of 1.5 mm2. The other end of the screen on the 3WN1 connecting cable must be earthed on the SUB-D connector of the circuit-breaker using a flexible wire (as short as possible) with a crosssection 2.5 mm2.

All rights reserved. Version 1.0 (08/98) Communication System Manual 3WN1, 3WS1 Circuit-Breakers 4.5.6 Displaying data in PROFIBUS-DP Any standard PROFIBUS-DP master can exchange data with the interface module. Even very "simple" master interfaces can be used thanks to the data structure. Standard PROFIBUS-DP masters and slaves transmit and process four different types of message: * * * * Parameterization message Configuration message Diagnostic message Data message The general mode of operation of the communication link is described in the following: * After the master has determined which slaves are present on the bus, it sends first a parameterization message and then a configuration message to each slave. After the slave (interface module) has received the parameterization and configuration messages, master and slave can start the data exchange cycle (= normal operating state). * If diagnostic data or faults occur in the DP slave (interface module), e.g. "3WN1/3WS1 communication interface not clear", the slave (interface module) transmits a high-priority message instead of a low-priority message. The master recognizes this and requests the diagnostic data from the slave for the purposes of a more detailed analysis. Note ! Type or GSD files All the data (see Parameterization, Configuration) required by the interface module for normal operation are available in the form of a type or GSD file, which you will find on the supplied diskette. No further data need to be entered by the user. The following section describes the four message types in detail. 4.5.6.1 Parameterization The master identifies itself to the slave by means of the parameterization message and defines the mode in which the slave (interface module) is to operate. The following parameterization options are available as standard: * Slave operation with/without watchdog (response monitoring). This is necessary for safety reasons as it makes it possible to detect whether a master is still active. * Definition of TSDR (the minimum delay time which must elapse before a slave can respond) * Operation of slave in Freeze/Sync mode (e.g. for actuators, counters) * Enabling/disabling of DP slave for other masters. * Issuing of a group assignment for "global control" messages. Each bit signifies a group. * Master address for unique identification * User-specific parameters (e.g. response to CLEAR master status) Version 1.0 (02/98) Copyright Siemens AG 1998. All rights reserved. 107 Communication System Manual 3WN1, 3WS1 Circuit-Breakers The parameterization message from the master to the interface module is structured as follows: Table 17: Parameterization message SD 68H LE x LEr x Octet SD x DA 8x Bit no.

Nothing lower than the digit "2" should ever be entered in one octet and nothing lower than the digit "1" in the other, in order to ensure that the watchdog time does not elapse too quickly. A time base of 1 ms is specified in the user parameters of some ASICs due to the 12 Mbaud technology. ** 11 Tbits minimum are specified as standard. This value must be less than the maximum TSDR. *** The structure of the parameterization message is partly specified as is the case with ASICs LSPM2/SPM2. The SPC3 evaluates the first 7 (without user_prm_data) or the first 8 (with user_prm_data) data bytes. The first seven bytes are defined in accordance with the standard. The eighth byte is used for SPC3-specific properties and the other bytes are available for the application. Response from slave The slave responds to a parameterization message with "E5H" (short acknowledge). The slave does not report parameterization errors until later when it receives a diagnostic request from the master. 108 Copyright Siemens AG 1998. All rights reserved. Version 1.0 (08/98) Communication System Manual 3WN1, 3WS1 Circuit-Breakers 4.5.6.2 Configuration When parameterization is complete, the master sends a configuration message to the slave. The configuration message causes the slave to check the transmitted configuration with reference to the stored configuration. You can describe up to 16 bytes or words in one octet of the data unit (DU). You can group inputs and outputs with the same format in one octet. Otherwise you must use a separate octet for each individual byte/word.

This service program is especially useful for modular systems. Response from slave The slave responds to a configuration message with "E5H" (short acknowledge). If the slave detects discrepancies as compared with the entries in the GSD file, it report the configuration errors later when it receives a diagnostic request from the master. It is not ready for user data traffic in this case. 4.5.6.3 Diagnostics Diagnostic data are high-priority data.

All rights reserved. 113 Communication System Manual Appendix 5.2 Glossary - 3RK1 interface module The 3RK1 interface module translates the PROFIBUS-DP data format to the circuit-breaker data format and vice-versa. There are two 3RK1 interface modules: 3RK1000 (also known as DP/3WN6) for 3WN6 circuit-breakers and 3RK1002 (also known as DP/3WN1, 3WS1) for 3WN1 and 3WS1 circuit-breakers. - AS-i: - Baud: - Bus configuration: - DP: - DP/3WN6: - Gateway: - GSD: - I/O area: - Octet: - PLC: - PROFIBUS node: - Reaction time: 114 Actuator-Sensor-interface. The AS-i is a supplier-independent networking system for simple, usually binary, actuators and sensors. It is possible to connect this interface to all the standard automation systems in the SIMATIC family using various master modules. For further information, please refer to Catalog ST PI 96: "PROFIBUS & AS-Interface - Fieldbus Components" (order no. E86060-K4660A101-A1) Unit of measurement for transmission rate. A rate of 1 baud means that 1 bit ("0" or "1") is transferred per second. Definition of 3WN6 device-specific data, the bus address of 3WN6 and the 3WN6 data area (I/O area) in the bus master Decentralized Peripherals. Name of the interface which translates the 3WN6 data profile to the PROFIBUS-DP profile and vice versa. The DP/3WN6 interface was previously also known as the "DP/RS485" or "kNS/DP" interface. A gateway is used to translate data formats of one system (e.g. PROFIBUS protocol) to data formats of another system (e.g. 3WN6 data profile) The term "interface" or "interface module" is used in this documentation instead of the term "gateway". Device data file This refers to the storage area of the bus master (e.g. SIMATIC S5 PLC) which is reserved for communication between the circuitbreaker and the bus master when the 3WN6 circuit-breaker is connected to PROFIBUS-DP. The size of the memory area reserved for 3WN6 is 12 bytes (octets). The term "octet" is a synonym of the term "byte" and stands for 8 binary data units (bits). Programmable Logic Controller A field device which is connected to PROFIBUS The total time required for the processing and execution of a command from the bus master. Please refer to Appendix A.5 for the 3WN6 reaction times on the bus. Copyright Siemens AG 1998. All rights reserved. Version 1.0 (08/98)
