Extended fieldbus diagnostics The extended fieldbus diagnostics allows the configuration and comprehensive diagnostics of the complete bus segment: Interface module Coupler Field distributor Connecting cables between the components (AS; bus link and field devices) If the bus link is configured exclusively with EFD-capable components, you can take advantage of the benefits of the extended field bus diagnostics: Rugged infrastructure components - higher ruggedness of the complete system Diagnostics information for reliable commissioning of the fieldbus installation Diagnostics messages in PCS 7 Alarm handling in SIMATIC PDM Consistent information flow of the system status diagnostics Preventive maintenance measures during operation to prevent system downtimes 2.2.2 EFD system How do extended fieldbus diagnostics work? The interface module (IM 153-2) maps the status information of the entire connected bus segment. The installed couplers (FDC 157) and active field splitters/distributors (AFS and AFDxxx) determine the status of the connected lines and the physical data of the bus segment and communicates this to the interface module. The information obtained is then displayed using the PCS 7 maintenance station and can be evaluated using SIMATIC PDM.

Requirement: Interface module, couplers and field devices must be configured in STEP 7. Each field distributor is initialized with a reserved identifier that cannot conflict with the address mechanism of the respective fieldbus system. The interface module can determine the data of the connected fieldbus segment independent of the topology (line, ring, star topology) and make this available to the user via SIMATIC PDM. The extended fieldbus diagnostics provides status displays for: Bus link (interface module and coupler) Field bus Each connected field distributor (AFDiSD including the physical layer of the connected spur lines) Extended fieldbus diagnostics in PROFIBUS PA Operating Instructions, 05/2015, A5E32591680-AA 11 Product overview 2.2 EFD system (bus link with extended fieldbus diagnostics) Licensing for extended fieldbus diagnostics For the extended fieldbus diagnostics with SIMATIC PDM, you need the following licensing for each bus link: SIMATIC PDM TAG: 50 TAGs per segment (applies also to redundant configuration) PDM license concept The following table shows the number of SIMATIC PDM TAGs contained in the product: Product package Version SIMATIC PDM TAGs contained SIMATIC PDM PCS 7 V8.2 100 SIMATIC PDM PCS 7-FF V8.2 100 SIMATIC PDM S7 V8.2 100 SIMATIC PDM Service V8.2 100 SIMATIC PDM Basic V8.2 4 You can increase the number of TAGs at any time with accumulative sets of 10, 100, or 1000 TAGs. One TAG corresponds to one SIMATIC PDM object, which represents individual field devices or components within a project, e.g. measuring instruments, positioners, switching devices or remote I/Os. TAGs are also relevant for diagnostics with the lifelist of SIMATIC PDM. You can find more information about PDM product packages and ordering information on the Internet (http://support.industry.siemens.com/cs/document/73247204?lc=en-US). Automation License Manager (ALM) You can find information on handling the required license keys and management program Automation License Manager (ALM) on the Internet (http://support.industry.siemens.com/cs/ document/114358?lc=en-US). 12 Extended fieldbus diagnostics in PROFIBUS PA Operating Instructions, 05/2015, A5E32591680-AA Description of the components 3 Interface module (IM 1532 (Outdoor)) The released interface module is the communication connection of the bus link. The interface module collects all data of the lower-level components (couplers, field distributors, and connected bus segment). For the extended fieldbus diagnostics, the interface module provides an interface to the diagnostics in SIMATIC PDM or PCS 7. Coupler (FDC 157) The released coupler is the physical connection to the lower-level bus segment. For the extended fieldbus diagnostics, the coupler must be configured in STEP 7. Field distributor (AFDiSD) The field distributor is used for connection of the field devices to the bus segment. For the extended bus diagnostics, you enable the diagnostic capability of the field distributor using a mode selector (see section Enabling/disabling extended fieldbus diagnostics at the field distributor (Page 20)).

You can find detailed information and download the "SIMATIC Fieldbus Calculator" from the Internet (http://support.industry.siemens.com/cs/document/53842953). Requirement Use for the bus link to the PROFIBUS PA Calculation of bus segments before commissioning 1. Determine the components of the bus segment required for your automation task and their layout. 2. Use the "SIMATIC Fieldbus Calculator" to check the physical requirements for the bus segment on the basis of the relevant physical data of the components (line lengths, basic current of the devices, topology, etc.). Based on the entered data and the configuration, the "SIMATIC Fieldbus Calculator" evaluates compliance with the physical and electrical characteristics. 3. If the "SIMATIC Fieldbus Calculator" detects that a limit has been exceeded, you must correct the configuration of the bus segment, for example by changing the line lengths, moving field devices into other bus segments, or distributing the field devices among several bus links. 4. If the "SIMATIC Fieldbus Calculator" confirms that the corrected configuration complies with the physical and electrical quantities, configure the field devices used in your configuration in STEP 7 HW Config. 5. Mount the bus segments in accordance with the verified configuration and connect them. 6. Commission the bus link with extended fieldbus diagnostics (see section Commissioning: EFD system (Page 17)).

Recommendation: Reset the PROFIBUS address of the interface module before removing it. Extended fieldbus diagnostics in PROFIBUS PA Operating Instructions, 05/2015, A5E32591680-AA 17 Commissioning: EFD system 5.3 Setting the PROFIBUS address and redundancy mode of the coupler Procedure 1. Switch off the power supply. 2. Set the PROFIBUS address of the interface module with the DIP switches to "0" (all switches to the left). 3. Switch on the supply voltage. The interface module is reset. Note Effects: The following data is reset to the default settings: - Internal parameter "Fieldbus diagnostics enabled" - EFD configuration is deleted I&M data (Identification & Maintenance) remain stored. 4. Check the LED displays: A reset is complete when the LEDs have the following status: - BF1 LED: Flashes - All other LEDs have the status: Off 5. Switch off the power supply. 6. Set a valid PROFIBUS address for the interface module. 5.3 Setting the PROFIBUS address and redundancy mode of the coupler Introduction Setting the bus address of the coupler is not necessary to operate the bus link. In the delivery state, the bus address is set to "0" and the redundancy mode is set to "coupler redundancy". Rules The only bus address allowed for (both) couplers is "0". The redundancy mode that is set on the coupler pair ("RING" switch) and in the configuration (ring or coupler redundancy) must match. PROFIBUS address 124 is reserved for internal purposes when the EFD system is used. Configuring or setting of the PROFIBUS address 124 is not permitted for any components on the bus segment when the EFD system is used.. With ring redundancy, the FDC 157 on the left ("Coupler 1") must have a lower PA address than the FDC 157 on the right ("Coupler 2")! 18 Extended fieldbus diagnostics in PROFIBUS PA Operating Instructions, 05/2015, A5E32591680-AA Commissioning: EFD system 5.3 Setting the PROFIBUS address and redundancy mode of the coupler Tools required 3 mm screwdriver Commissioning with extended fieldbus diagnostics 1.

Note When using the extended fieldbus diagnostics, open the EDD only via HW Config. If you want to open the EDD via the network view, observe the following: Determine which interface module is connected to the master H-CPU. For the access, select the interface module that is connected to the master H-CPU. Requirement SIMATIC PDM, including the required license keys, is installed on a computer. The computer is connected to an automation system. The bus link is completely installed and wired. You have created a project in SIMATIC Manager. You have created an automation system with a PROFIBUS DP master system in HW Config. You have made the additional settings for the extended fieldbus diagnostics (see section Configuring the bus link with STEP 7 (Page 21)). The device description file (EDD) for the interface module is imported. The device description files (EDD) for the field devices are imported. CPU and bus link (interface module and coupler) are switched on. The project is loaded on the CPU. Note Before and during configuration of the extended fieldbus diagnostics, the interface module signals alarms for lower-level components (couplers and field devices) to the automation system, which you can ignore. These alarms are reported as "outgoing" the farther along the configuration of the extended fieldbus diagnostics is towards being completed. Exception: there are other errors in the plant. Basic procedure The most important steps are: Enable extended fieldbus diagnostics Configure the EFD components or check their configuration (interface module, coupler, field distributors). 22 Extended fieldbus diagnostics in PROFIBUS PA Operating Instructions, 05/2015, A5E32591680-AA Commissioning: EFD system 5.6 Configuring the extended fieldbus diagnostics using SIMATIC PDM Configure the EFD system or check its configuration. Read/save I&M data (Identification & Maintenance) (interface module, coupler, field distributors) Possible procedures: Recommendation: Using the Commissioning Wizard for extended fieldbus diagnostics (Page 23) In order to avoid errors/problems when commissioning, you should use the Commissioning Wizard. Manually configuring the extended fieldbus diagnostics (Page 23) 5.6.2 Using the Commissioning Wizard for extended fieldbus diagnostics Configuring the extended fieldbus diagnostics using SIMATIC PDM To configure the extended fieldbus diagnostics, proceed as follows: 1. Select the menu command Device > Commissioning wizard in PDM. 2. Follow the on-screen instructions. Additional information You can change the tolerances for measured value deviations for the main line and spur line in the wizard. The default parameters can be found in section "Technical specifications (Page 67)". See also Elimination of errors with the extended fieldbus diagnostics (Page 44) 5.6.3 Manually configuring the extended fieldbus diagnostics If you do not want to use the recommended Commissioning Wizard for configuring the extended fieldbus diagnostics, perform the steps in this section. Locating field distributors in the plant SIMATIC PDM provides the "Find AFDiSD x" function for locating field distributors in the plant. You can find the "Find AFDiSD x" button in the "Device" area of the parameter table of the "AFDiSD x". When you click this button, all LEDs of the spur lines to the field devices (S1 to S6) flash for 5 s on the sought-after field distributor. Extended fieldbus diagnostics in PROFIBUS PA Operating Instructions, 05/2015, A5E32591680-AA 23 Commissioning: EFD system 5.6 Configuring the extended fieldbus diagnostics using SIMATIC PDM Procedure 1. Start STEP 7 and open your station in HW Config. 2. Double-click the interface module (IM 153-2) in HW Config. Result: SIMATIC PDM is started. 3. Select the PDM menu command Device > Enable extended fieldbus diagnostics. Result: The topology of the connected bus segment is determined. This process can take up to 3 minutes. SIMATIC PDM is blocked during this time. When the topology discovery is finished, the parameters of the lower-level objects are displayed in the parameter table in SIMATIC PDM. Some of the parameters can be edited. 4. In SIMATIC PDM, check to make sure the discovered topology/parameters match the actual topology for the connected bus segment. Does the displayed arrangement of the field devices in the configuration match the actual arrangement of the devices in the field? - Configuration: You can find the serial number in the parameter window. - Devices in the field: You can find the serial number on the sticker attached to the outside of the device on its right side. Association between the parameter table and the actual configuration - During operation with coupler redundancy, the upper "Coupler 1" button is associated with the FDC 157 on the left, and the lower button "Coupler 2" is associated with the FDC 157 on the right. - The "AFDiSD 1" button is associated with the first field distributor that is connected to "Coupler 1" . - The "AFDiSD 2" button is associated with the first field distributor that is connected to "AFDiSD 1". Note Eliminating errors If errors that require an intervention in the plant occur, follow this sequence to continue with commissioning: 1. Disable the extended fieldbus diagnostics (see section "Disabling extended fieldbus diagnostics (Page 41)"). 2. Disconnect the plant from the power supply. 3. Eliminate the error(s) in the plant. 4. Reconnect the plant to the power supply. 5. Continue the configuration beginning with step 3 above (menu command Device > Enable extended fieldbus diagnostics). 5.

Select the bus link in SIMATIC PDM and select the menu command Device > Download to Devices. Wait about 30 s after the download has finished until the settings take effect. 24 Extended fieldbus diagnostics in PROFIBUS PA Operating Instructions, 05/2015, A5E32591680-AA Commissioning: EFD system 5.6 Configuring the extended fieldbus diagnostics using SIMATIC PDM 7. Save the current actual topology of the EFD system as the set topology in the interface module: Note: You must perform this step even if you do not make any changes to the spur line. - Use the menu command Device > Upload to PG/PC to upload the current data for the bus link to your programming device or PC. - Download the data back to the bus link with the menu command Device > Download to Devices. Result: The interface module retentively saves the data of the current configuration for diagnostic purposes. This set topology of the EFD system remains stored even after the power supply has been switched off. 8. Optional: Settings in the parameter table: - You can change the tolerances for measured value deviations for the main line and spur line in the specified range. You can find the standard parameters in section "Technical specifications (Page 67)". If a measure value exceeds or falls below the tolerance range, this leads to an EFD diagnostic message; see section Elimination of errors with the extended fieldbus diagnostics (Page 44) for more information. - You can enter the I&M data (identification and maintenance) of the components (interface module/coupler/field distributors) according to the plant requirements. If you have made optional settings, select the menu command Device > Download to Devices. 9. Clear the error memory (see next section "Clearing the error memory"). Note Once commissioning is successfully completed (commissioning status "Completed") the following applies: Menu command Device > Upload to PG/PC Menu command is not executed. This protects the values stored in the parameter table during commissioning of the EFD system from inadvertent read-back (Upload to PG/PC). The protection continues to apply until values are changed in the parameter table. Menu command Device > Download to Devices You can execute the menu command at any time.

Modifying a bus segment You can modify a bus segment during operation if the following applies: Adding/removing of field devices to/from the existing field distributor Adding/removing of a field distributor at the end of the bus segment - In non-redundant mode - With coupler redundancy - With ring redundancy (the end of the bus segment is located before the coupler on the right). Extended fieldbus diagnostics in PROFIBUS PA Operating Instructions, 05/2015, A5E32591680-AA 37 Service and maintenance 6.9 Firmware update of the field distributor Note Modification of the bus segment before the last field distributor If you modify a bus segment before the end of the bus segment, you must accept the fact that problems will occur starting from the "disconnection point" even with a redundant configuration. Pay attention to where you modify the bus segment. The bus addresses of the field distributors after the "disconnection point" are changed. After the "disconnection point", communication with the field devices located in the segment is disturbed. It is possible that process values will not be transmitted. To modify a bus segment, follow these steps: 1. Switch off the power supplies of the bus link (to interface module and coupler). 2. Verify the new configuration (number of components, total current) of the bus segment with the SIMATIC Fieldbus Calculator (http://support.industry.siemens.com/cs/document/ 53842953). 3. Make desired changes to the bus segment in accordance with the results. 4. Switch on the power supplies of the bus link again. 5. Repeat the commissioning, see section Commissioning: EFD system (Page 17). 6.9 Firmware update of the field distributor When should you update the firmware? When a plant stoppage is scheduled, you should check whether an update of the firmware version is available. New firmware version generally offers added functions or performance improvements. Recommendation: Update the components to the newest firmware version (update) in each case. "Activate firmware after download" option Note the possible effects of the "Activate firmware after download" option: Option is disabled The firmware update download does not have any effect on the ongoing operation of the bus link. The new firmware is stored in the field distributor and is only activated at the next restart of the field distributor, which means that the startup takes longer on this occasion. 38 Extended fieldbus diagnostics in PROFIBUS PA Operating Instructions, 05/2015, A5E32591680-AA Service and maintenance 6.9 Firmware update of the field distributor Option is enabled After the firmware update has been downloaded, the field distributor carries out a restart so that field devices connected to the field distributor are disconnected from the bus segment. In case of non-redundant operation or operation with coupler redundancy: - All field distributors from the updated field distributor onwards are shut down briefly (time for a restart), including all connected field devices. - All field distributor after the updated field distributor are integrated in the bus segment again. In case of operation with ring redundancy: - Updating the firmware of a field distributor does not have any effect on the ongoing operation of the remaining bus segment. - The updated field distributor is shut down for a restart, including the connected field devices. Firmware update blocked If a firmware update has been interrupted, the status of the field distributor is not defined. A restart of the field distributor is required because a repeated attempt to perform the firmware update is blocked. Switch the field distributor off and back on as soon as possible. Requirement You need the associated STEP 7 project including SIMATIC PDM. The current version of the firmware of the field distributor is known. You have specified the time for installing the new firmware (see: "Activating firmware after download" option) Ensure that the required firmware version is available on the PDM computer.

Check whether the causes of the messages persist. If the EFD system is operating error-free, you can clear the error memory (see section "Manually adding/removing/ replacing a field device during operation (Page 35); Clearing the error memory"). Disabled messages Certain warning and alarm limits can be disabled using PDM. For example, if you have disabled the limit for "Trunk Jitter Max", you will not receive messages for this physical value: No "Maintenance required" warnings No "Out of specification" alarms Extended fieldbus diagnostics in PROFIBUS PA Operating Instructions, 05/2015, A5E32591680-AA 45 Alarm, fault and system messages 7.4 Elimination of errors with the extended fieldbus diagnostics Procedure 1. You must open SIMATIC PDM for the diagnostics of the EFD system. - If a PCS 7 Maintenance Station is present in the plant and it has access to the engineering station with SIMATIC PDM, you can open SIMATIC PDM in the case of a message related to the EFD system directly from this message. - You can open SIMATIC PDM via HW Config. Double-click the interface module in HW Config. 2. Select the status overview of the complete EFD system online with the menu command Device > Extended fieldbus diagnostics data. 3. Check the received status messages in the "Extended fieldbus diagnostics data" dialog.

Diagnostics active Component is functioning properly. Current status and previous status The "Extended fieldbus diagnostics data" dialog and the lower-level dialogs for "Topology", "Coupler" and "AFDiSD" additionally display the status signals for two different states of the EFD system: "Current status" This column displays the status of the EFD system and its components on the basis of the last monitoring cycle. "Previous status" This column displays the most serious error since the commissioning status was last set to "Completed" (by means of the "Overwrite previous status with current status" button). These two columns help, for example, by showing an error which incurred after the last setting the commissioning status to "Completed" (= previous status: "Outside the specification"), but was not detected during the most recent monitoring cycle (= actual status: "Diagnostics active"). This can be caused, for example, by a loose contact on a spur line. Locating field distributors in the plant SIMATIC PDM provides the "Find AFDiSD x" function for locating field distributors in the plant. You can find the "Find AFDiSD x" button in the "Device" area of the parameter table of the "AFDiSD x".

Rules Always handle EFD alarms first. Work through the status overview of the EFD bus segment from top to bottom and handle the error messages in accordance with their severity. A failure can be the reason for the display of further error or maintenance required messages at the subsequent components in the bus segment. When a failure is eliminated, it is therefore possible that subsequent error displays are also eliminated. Deal with all the components that are identified by the "Failure" symbol first: - Click the respective option button to open the associated dialog of the affected component. - Eliminate the displayed error. For this purpose, read the information in the following sections. - Update the "Extended fieldbus diagnostics data" dialog by clicking the "Overwrite previous status with current status" button. Next, handle all error messages that are identified by the symbol "Outside the specification" in the same manner. Finally, handle all error messages that are marked with the symbol "Maintenance required" in the same manner. Eliminate any further errors displayed until all the status displays are set to "Diagnostics active". When no more EFD alarms are displayed: Eliminate any other existing errors. 7.4.2 Topology 7.4.2.1 Topology: Eliminating the "Failure" diagnostics status Requirement In the "Extended fieldbus diagnostics data" dialog, one or more "Failure" diagnostics states exist for the topology.

See Set topology. Actual values from commissioning See Set topology. Bus A common transfer route to which all nodes are connected; it has two defined ends. Bus connector Physical connection between bus node and bus line. Coupler The Field Device Coupler connects a PROFIBUS PA segment to a PROFIBUS DP segment. PROFIBUS PA and PROFIBUS DP are coupled to one another in terms of data but are separate in terms of the transmission physics. Diagnostic interrupt Diagnostics-capable components report system errors they have detected to the central CPU by means of diagnostic interrupts. In SIMATIC S7: When an error is detected or disappears (e.g. wire break), provided the interrupt is enabled, the module initiates a diagnostic interrupt. The CPU interrupts the processing of the user program and lower priority classes and processes the diagnostic interrupt block (OB 82). Diagnostics Diagnostics is the detection, localisation, classification, display and further evaluation of errors, faults and messages. Diagnostics provides monitoring functions that run automatically while the plant is in operation. This increases the availability of plants by reducing commissioning times and downtimes. DP master A master that behaves in conformity with IEC 61784-1:2002 Ed1 CP 3/1 is termed a DP master. Extended fieldbus diagnostics in PROFIBUS PA Operating Instructions, 05/2015, A5E32591680-AA 75 Glossary DP slave A slave that is operated on the PROFIBUS bus with the PROFIBUS DP protocol and that behaves in conformity with IEC 61784-1:2002 Ed1 CP 3/1 is termed a DP slave. DP standard is the bus protocol of the distributed I/O system in compliance with IEC 61784-1:2002 Ed1 CP 3/1. EDD file Standardized device descriptions (EDD - Electronic Device Description) permit the integration of intelligent field devices from different manufacturers into different control systems. The IEC 61804-3 standard stipulates the structure of device descriptions. This standard has been developed in cooperation with the following organizations: PROFIBUS International (PI) HART Communication Foundation (HCF) Fieldbus Foundation OPC Foundation The EDDL (Electronic Device Description Language) is used as basis for the device descriptions. EFD See: Extended fieldbus diagnostics EFD system If all components involved in the bus link (interface module, field device coupler, active field distributors) support extended fieldbus diagnostics (EFD), this configuration is referred to as an EFD system. Equipment, associated A piece of electrical equipment that contains both intrinsically safe and non-intrinsically safe power circuits and is configured so that the non-intrinsiclly safe power circuits cannot impede the intrinsicaly safe ones. Equipment, electrical Components, power circuits or parts of power circuits that are normally to be found in their entirety in a single enclosure. Equipment, intrinsically safe, electrical A piece of electrical equipment in which all power circuits are intrinsically safe. 76 Extended fieldbus diagnostics in PROFIBUS PA Operating Instructions, 05/2015, A5E32591680-AA Glossary Extended fieldbus diagnostics The extended fieldbus diagnostics allows the configuration and comprehensive diagnostics of the complete bus segment: Interface module Field device coupler Active field distributors Connecting cables between the devices Field bus The field bus is a serial bus system for the distributed integration of field devices in an automation system. Ground Ground refers to the entirety of all interconnected inactive parts of equipment that, when correctly installed, cannot conduct dangerous contact voltage even in the event of a malfunction. GSD file All slave-specific properties are stored in a Device Data Base File (DDBF file). The format of the DDBF file is to be found in the PROFIBUS guideline: Specification for PROFIBUS Device Description and Device Integration Vol.1: GSD V4.1, 07/2001 of the PROFIBUSNutzerorganisation (PNO). Hazardous area (Ex area) Area in which a potentially explosive gas atmosphere is present or expected in such quantities that special measures with regard to the design, installation and use of equipment are required. HW Config Part of STEP 7 for configuration of hardware. I&M data (Identification & Maintenance) Identification data (I data) is information on the module, some of which are printed onto the module enclosure. I data are for reading only. Maintenance data (M data) is plant-dependent information such as installation location, installation date etc. M data are created during configuration and written onto the module. Extended fieldbus diagnostics in PROFIBUS PA Operating Instructions, 05/2015, A5E32591680-AA 77 Glossary I&M data is information stored in a module that supports you when Checking the plant configuration Locating hardware modifications in a plant Correcting errors in a plant Modules can be uniquely identified online by means of the I&M data. Master When a master is in possession of the token, it can send data to other nodes and request data from other nodes (= active node). DP master are, for example, the CPU 315-2 DP or the IM 308C. PNO PROFIBUS user organization PROFIBUS PROcess FIeld BUS, process and field bus standard as defined in the field bus standard (IEC 61784-1:2002 Ed1 CPF 3 PROFIBUS and PROFINET). It specifies functional, electrical, and mechanical properties for a bit-serial field bus system. PROFIBUS is available with the protocols: DP (=distributed I/O) and FMS (= Field bus Message Specification). PROFIBUS address For the purpose of unique identification on PROFIBUSDP, each node must be given a PROFIBUS address. PC / PD or the ET 200 Handheld have the PROFIBUS address "0". DP master and DP slaves have a PROFIBUS address from the 1 to 125 range. PROFIBUS DP PROFIBUS bus system with the DP protocol. DP stands for the German equivalent of distributed I/O. PROFIBUS PA PA stands for Process Automation and increases the range of usage of the PROFIBUS DP family to include the field of process engineering. Process engineering refers to both the intrinsically safe sectors of the chemicals industry and to the non-intrinsically safe sectors, such as nuclear power plant automation, the food industry and waste water technology. 78 Extended fieldbus diagnostics in PROFIBUS PA Operating Instructions, 05/2015, A5E32591680-AA Glossary Redundant systems Redundant systems are characterized by the multiple (redundant) presence of important automation components. If a redundant component fails there the processing of the program is not interrupted. Segment A segent or bus segment is a self-contained section of a serial bus system. Set topology Topology of the EFD system that was stored retentively in the interface module at the time of commissioning. The topology of the EFD system essentially comprises the following values: Type of redundancy (coupler or ring redundancy) Number of couplers Number of field distributors The spur lines to which field devices are connected Actual values determined from the plant at the time of commissioning that are stored retentively in the interface module as setpoints (e.g., voltage and current) These values are also transferred to the parameter table in SIMATIC PDM at the time of commissioning. After successful commissioning, the setpoints in the parameter table match those stored in the interface module. Setpoints from commissioning See Set topology. SIMATIC PDM SIMATIC PDM (Process Device Manager) is a versatile tool for configuring, setting parameters, commissioning, and diagnostics of intelligent process devices from any vendor. SIMATIC PDM provides a uniform user interface for the configuration of a wide range of process devices with a single software package. Token In network technology a token refers to a bit pattern that is passed from one bus node to another, enabling that node to access the bus. Type of protection The special measures applied to electrical equipment to prevent the ignition of a potentially explosive ambient atmosphere.
