The basic mode of operation is also similar to operation of a configuration with standard modules from the programmable controller and TP/OP family; the individual components function independently, and each processor has its own dedicated memory. The C7-CPU and the C7-TP/OP communicate internally over the MPI interface. The C7-CPU is independent of the C7-TP/OP. The C7-TP/OP continues to run, for example, if the C7-CPU enters the STOP mode. Programming and Configuration Note The C7-CPU and the C7-TP/OP each have their own MPI address. Therefore, you program and configure these components in exactly the same way as independent CPU and TP/OP components. These items are addressed explicitly in the manual, as necessary. You program the C7-635 Touch with STEP 7 as of V 5.2 + Service Pack 1 + Hardware Update C7-635 Touch V2.0. You program the C7-635 Key with STEP 7 as of V 5.2 + Service Pack 1 + Hardware Update C7-635 Key V2.0. The programming languages you can use are listed in the CPU 31xC and CPU 31x, Technical data manual. The C7-635 is configured with ProTool, ProTool/Lite, or ProTool/Pro starting with V 6.0 + Service Pack 1. The tools run on a programming device or PC under Windows. C7-635 Control System A5E00155581-04 2-5 Product Overview CPU The user program controlling the process runs on the C7-635. The following functional units determine the mode of operation of the C7-635: * Loading memory The loading memory is located on the Micro Memory Card (MMC) and contains the user program. * Processor The processor executes the program cyclically: - At the beginning of the cycle, the processor reads the signal states on all inputs and generates a process image of the inputs (PII). - The program is executed step-by-step using internal counters, bit memory, and timers. - The processor stores the calculated signal states in the process output image (POI). At the end of the cycle, the process image is transmitted to the outputs. Touch Panel/Operator Panel The touch panel and the operator panel of the C7-635 are based on the standard Windows CE operating system. You can visually display operating modes, current process values, and faults. You can also make entries on the C7-635. Simple machine diagnostic functions are also possible. You can also incorporate your own graphics, digital pictures, and scanned images into your project. Moreover, you can represent elements such as temperature variations graphically using bar graphs and diagrams.

System-Specific Labeling The template for the labeling strips is provided with ProTool (V6.0 + Service Pack 2, directory Utilities) or can be obtained from the Internet. With it, you can design and print out system-specific labeling strips easily. Internet address: www.siemens.com/automation/service&support The file "SLIDE635.DOC" with the labeling strips can be obtained by selecting Product Support > Automation Systems > SIMATIC Industrial Automation Systems > PLC > SIMATIC C7 > Control Systems > Downloads To make your own labeling strips, use transparent film (0.1 to 0.15 mm thick) so that the LEDs in the function keys remain visible. Label the film using either a printer or a wipe-resistant foil pen. ! Caution To prevent the keyboard from smudging on the inside, the labeling must be covered with a transparent adhesive strip or a transparent adhesive film. Otherwise, operating pressure causes the labeling color to rub off on the inside of the key. A key that has been smudged from the inside cannot be cleaned and can only be replaced at the factory. The labeling strips have to be cut exactly along the indicated cutting edge. If the labeling strip is cut too large, it cannot be inserted. C7-635 Control System A5E00155581-04 3-1 Installing and Wiring the C7-635 The strip is inserted as follows: Step Action 1. Place the device with the front plate facing downward. 2. Remove any labeling strips that have been previously inserted. 3. With the labeling pointing downward, insert the new labeled strips into the slits on the front panel (use tweezers, if necessary). The position of the eight labeling strips is marked in Figure 3-1 with arrows. Labeling strips Figure 3-1 Inserting labeling strips for C7-635 Key 3-2 C7-635 Control System A5E00155581-04 Installing and Wiring the C7-635 3.2 Mechanical Installation Mounting The C7-635 is intended for stationary and enclosed installation in a control cabinet door. Note You can only achieve the degree of protection IP65/NEMA 4X if you follow steps 1 through 5 during installation. ! Caution The inserted CF card protrudes from the C7-635 and could therefore be damaged. Prior to the removal and installation of the device, remove the Micro Memory Card (MMC) of the CPU and the Compact Flash Card (CF Card) of the OP. ! Caution Condensation may develop on the device when you take it from a cold environment to the operating area. Before you start it, allow the device to become acclimatized to room temperature. If condensation has developed, the device may not be switched on until it is completely dry. Mounting is performed as follows: Table 3-1 Mechanical Installation Action Step 1. C7-635 Touch: Make a cutout in the control cabinet door (dimensions 231+1.0 x 183+1.0 mm). See Figure 3-3. C7-635 Key: Make a cutout in the control cabinet door (dimensions 231+1.0 x 257+1.0 mm). See Figure 3-4. 2. Ensure that no Compact Flash Card (CF Card) is inserted into the C7-635. The CF Card protrudes from the C7-635 and could be damaged when the device is installed. 3. Place the C7-635 in the prepared cutout in the control cabinet door. Ensure that the gasket is applied evenly to the metal plate. 4. Guide the fastening hooks of the provided mounting supports A (for the C7-635 Touch, 8 mounting supports; for the C7-635 Key, 10 mounting supports) into the intended recesses in the C7-635 housing.

This can only be ensured by use of an enclosed metal construction (cabinet mounting, for example). Low frequency (LF) or high frequency (HF) interference signals can reach the internal bus of the controller if the system is not grounded or shielded properly, causing a malfunction. Interference signals can also be caused when relays or contactors switch (very rapid changes in current or voltage; HF interference signals) or when two components of system have different grounding potentials (LF interference signals). Note You can find additional information about construction guidelines in the S7-300, CPU 31xC and CPU 31x: Hardware and Installation manual. Use/Installation of Fail-Safe Cables * Only shielded cables are permitted for all analog signals. * Cable shielding must be grounded on both sides for: - Controller cables - Bus cables - I/O device cables * Standard cables from Siemens comply with these requirements. * All plug connections must be screwed or clamped into place. * Signal lines must not be laid parallel to heavy current lines. A separate cable channel must be used that is separated from heavy current lines by at least 50 cm. 3-22 C7-635 Control System A5E00155581-04 Installing and Wiring the C7-635 Cabinet Design Devices that could introduce interference signals from outside into the cabinet must be placed far below the cabinet. The grounding terminal must be placed immediately at the cabinet entrance to directly ground cables capable of carrying interference signals. All shielded cables must be laid here with the shield. For double-shielded signal lines, only the outer shield is to be laid here. Long signal lines must be installed along the cabinet walls. It is important to use an EMC-compliant cabinet construction to reduce disturbance variables. All chassis ground connections in the cabinet are to be made with a large cable cross section and laid over a large surface. Analog devices located in the control cabinet must be isolated and grounded at a point in the cabinet (use a copper strip). The materials used should always contain the same type of metal (as a rule, do not use aluminum due to the risk of oxidation). All doors and plates (side walls, back wall, and ceiling) of the cabinet must be connected at least three times with cabinet framework (short, unpainted connections over a large surface). Note The following applies for systems that generate large amounts of electrostaticenergy (such as textile machines and special construction machines): The grounding conductors of the machine parts exposed to interference signals are to be connected to a special functional ground separated from the central grounding point of the cabinet (surface grounding with building construction, sheathing). Functional Ground (see Figure 3-17) to the cabinet ground with a Connect the functional ground cable lug and a cable with a minimum cross section of 4 mm2. C7-635 Control System A5E00155581-04 3-23 Installing and Wiring the C7-635 3.6 Connecting Shielded Cables Overview This section describes how to connect the shield of shielded signal lines to the ground. A grounding terminal is used to connect the shield directly to the ground of the C7-635. Procedure Proceed as follows to install the grounding terminal supplied with the C7-635 and the shield terminals: 1. Mount the grounding busbar at the position shown in Fig. 3-17, using the included screws 1 or, as an alternative, at this position 2 . 2. Install the shielding terminals on the grounding busbar as shown in Fig. 3-17. 3. Push the stripped ends of the cable shielding into the shielding terminals. 2 2 1 Functional ground Shielding terminal Figure 3-17 3-24 C7-635 with grounding busbar, shielding terminals, and terminal for functional ground C7-635 Control System A5E00155581-04 Installing and Wiring the C7-635 3.7 Coding Connector Parts to Prevent Incorrect Usage You can order a connector set with coding profiles and coding tabs as an accessory for the C7-635 (see accessories in Section 2.2). ! Caution It is highly recommended that you code the connectors, as unintentionally using the wrong connector may damage the device. Coding the Connectors The coding profiles and coding tabs (see Figure 3-18) enable you to code connectors without loss of pole to prevent incorrect usage. Use the following procedure: 1. Insert coding profile on connector part into the slots provided. 2. Insert coding carrier on the main housing into the corresponding recesses. A coding profile and a coding tab facing one another prevent the connector part from being inserted. If a coding profile and coding carrier do not face one another, the connector part can be inserted without difficulty. 8 9 10 7 6 5 4 3 2 1 Figure 3-18 C7-635 Control System A5E00155581-04 Preventing Incorrect Usage of Connectors 3-25 Installing and Wiring the C7-635 3-26 C7-635 Control System A5E00155581-04 Special Features of the C7-635 4 Deviations from the CPU314C-2 DP * Operating mode selection * Arrangement of additional S7-300 modules * Status display of the digital onboard I/O * User memory expanded from 48 Kbytes to 64 Kbytes * All integrated I/O inputs have a common reference ground Deviations from TP170 /OP170 B * RS 485 interface (MPI) can not be switched to RS 422 interface * No second RS 232 interface * No DP interface to TP/OP C7-635 Control System A5E00155581-04 4-1 Special Features of the C7-635 4.1 Operating Mode Selection Status and error LEDs Figure 4-1 Operating mode keys with touch LEDs C7-635 Touch Changing the C7-CPU Operating Mode The figure above uses the C7-635 Touch as an example. The function and position of the operating mode keys and the status and error LEDs are the same for the C7-635 Key. Select the CPU operating modes RUN, STOP, and MRES as follows using the operating mode keys: Each time you press a key, the CPU mode changes. The key must be pressed for at least 500 ms for the change to take place and the corresponding key LED (R, S, M) to illuminate. The key LEDs do not reflect the CPU operating mode, rather, they indicate the setting of the operating mode keys.

C7-635 Control System A5E00155581-04 5-1 Maintenance 5.2 Replacing the C7-635 Introduction A C7-635 is not designed for onsite repair. Therefore, a defective C7-635 must be replaced. To save the configuration of the TP/OP, you should have a Compact Flash Card (CF Card). You should make a backup of the configuration on the CF card as soon as you have finished commissioning the device, so that you can restore the configuration if the device becomes defective. ! Caution Prior to installing and uninstalling the device, remove the Micro Memory Card (MMC) of the CPU and the Compact Flash Card (CF Card) of the TP/OP. The inserted CF card protrudes from the C7-635 and could therefore be damaged. How you proceed depends on whether you have backed up the TP/OP configuration on a CF Card. With CF Card Requirements * You have inserted a CF Card. * You have a new gasket. The gasket must be replaced each time the C7-635 is installed or uninstalled. The gasket is part of the service pack (see Section 2.2). Assembly Step 5-2 Action 1. Create a backup of the TP/OP configuration on the CF card. You should create the backup immediately prior to uninstalling the device so that current data (such as recipes) are included. Refer to the "Touch Panel TP170 A, TP 170 B, Operator Panel OP170 B" manual for information about how to make a backup copy. 2. You do not need to take special action to back up the user program on the CPU. It is saved as a non-volatile program on the MMC. 3. Switch off the power supply. 4. Loosen the cables from the shielding terminals and remove all connectors. 5. Remove the MMC and the CF Card. 6. Loosen the mounting supports with a screwdriver and remove the device from the control cabinet. C7-635 Control System A5E00155581-04 Maintenance Installation Step Action 1.
