Integrated inputs and outputs on the CPU C How do I optimize communication with the help of the respective manual We shall then go on to explain the basic rules that you should follow, and how you can modify maunal existing system. You must at least keep to these basic rules if you want your S7 system to operate correctly.
The mabual diagram illustrates a possible configuration: Additional properties of specific CPUs: This performs communication for the CPU, e. CP DP Accessory: Front connector module with ribbon cable terminals Interface module IM Connects the individual rows in This means that you must always install the S in a cubicle, cabinet or electrical control room that can only be accessed using a key or tool. Only trained or authorized personnel are allowed access to such cubicles, cabinets or electrical operating rooms.
Always install the CPU and power supply on the left or at the bottom. The S assembly on multiple racks shown in the figure below specifies the clearance between racks and adjacent components, cable ducts, cabinet walls etc. The power dissipation capability of a cabinet depends on its type, ambient temperature and on the internal arrangement of devices.
S Automation System, Hardware and Installation: It shows you the applied principle of heat dissipation, the calculated maximum power loss and the degree of protection.
The type of components and the degree of compulsion pertaining to the protective measures will depend on the VDE specification applicable to your particular plant. A grounding slide contact is used for this except with CPU 31xC. If you have already installed and wired up the CPU, you may have to detach the connection to the MPI interface before you pull out the grounding slide contact. The connection is automatically generated for the CPU 31xC 1. Low-impedance connections large surface, large- surface contact reduces the effects of interference on the system or the emission of interference signals.
If you connect only one end of the shielding that is, at one or the other end of the cable to ground, you will merely achieve an attenuation in the lower frequency range. The table below shows how to connect the load voltage reference potential M external for the various configuration versions. For this type of communication you require PtP communication processors CP.
You require this RS Repeater in the following situations: PG via a normal PG cablethen you must consider the maximum possible length cpy313c the stub cable. Information on this topic can be found in the RS repeater product information.
A bus segment must always be terminated at both ends with the terminating resistor. This, for example, is not the case if the last slave with bus connector cpu33c off power.
Templates for labeling strips are available on the Internet at http: Signal module SM 1 bus connector For electrical interconnection of modules Cut manuaal 2 m rail to the required length.
In the case of varnished or anodized metals, for instance, use a suitable contacting agent or contact washers. Manuak bus connector is included per module, but not for the CPU. The table below shows the slot number assignment. Hold the corresponding slot number in front of the relevant module.
Insert the pin into the opening on the module 1. Press the slot number into the module 2.
The slot number breaks off from the wheel. Connect the protective conductor to the rail, using the M6 protective conductor bolt. Minimum cross-section of the protective conductor: Open the strain relief on the PS Manyal the power cable to a length of 11 mm and connect it to L1, N and to the ground conductor terminal of the PS DUQLQJ You can damage the spring-based opening mechanism of the front connector if the screwdriver slips sideways or if you insert the wrong size of screwdriver.
Always slide a suitable screwdriver vertically into the desired opening until it reaches the stop. DUQLQJ You may come into contact with live wires if the power supply module and any additional load power supply units are connected to the mains.

You should therefore disconnect the S from the power supply before starting the wiring. Do you want to exit the cables at the bottom of the module? LULQJ The two rows of the shielding contact element allow you install cpu31c maximum of 4 shielding terminals.
LULQJ If you need more than four shielding terminals, start wiring at the rear row of the shielding contact element. Information on how to wire the bus connector can be found in the article below. Insert the wired bus connector into the module. Screw-tighten the bus connector on the module.
If the bus connector is at the start or end mwnual a segment, you have to enable the terminating resistor Switch position “ON” Here, you specify the module start address that forms the basis for all other addresses of the module. The bit address is the number printed on the module. Insert the first digital module into slot 4 so that it has default start address 0.
Slot number 3 has not been assigned since there is no interface module in the example.

It is therefore inappropriate to initially start up an S with multiple racks and all inserted installed modules. Rather, we recommend a step-by-step commissioning procedure. The checklist tables below are a guide for your examination of the S They also provide cross-references to chapters containing further information on the relevant topic. The following picture illustrates two networked Ss which are connected to one another using bus connectors.
The bus connector of these nodes must be equipped with a PG socket.
Siemens CPU 313C Hardware And Installation Manual
The figure below shows the interconnection of two networked S and a PG. To connect it to an MPI subnet with “unknown” node addresses, set the following addresses on the service PG: You can set up the MMC as a load memory or a portable data medium.
Is an MMC already inserted? If yes, ensure that no write operations are running on the PG such as loading a block. If you cannot ensure this state, disconnect all communication lines of the CPU. If the CPU prompts you for a memory reset, you only have to turn the mode selector briefly to MRES position to initiate the memory reset operation.
The CPU deletes the retentive data. The CPU tests its own hardware. The content of the MCC was identified as invalid. In order to monitor or control variables it is required to establish a connection to the relevant CPU. Every variable tables can be linked to another CPU. With a CPU as DP-Slave, for example, diagnostic interrupts for operating mode transitions are reported at this address.
Should you require a description of the configuration and parameter assignment frame, in order to use a bus monitor for example, you can find it on the Internet at http: The addresses used in the example are found in the table above.
Switch off the load voltage to the module. Remove the labeling strip from the module. Open the front panel. Unlock the front connector and remove it. This part is already inserted in the wired front connector. Install new module of same type. Pivot the module down into place. Slide the labeling strips into the module. Reinstall the front connector. Close the front panel. Switch the load voltage back on. The fuses are located at the left side of the digital output module.
The figure below shows you the location of the fuses on digital output modules. Tracking these errors might be a time-consuming effort, since they can occur likewise on hardware and on software side. Here, the multitude of testing functions ensures commissioning without problems. This location holds error information in plain text. Other modules capable of diagnostics can be equipped with their own diagnostic buffer. You can locate the cause of an error in the user program cycle with the help of the diagnostic buffer and of the stack content.
Usually you evaluate the diagnostic buffer for further error localization.
