1. Install the CP on the S7 standard rail.
2. Establish the connection via the enclosed bus

connector to the backplane bus.

Slots 4 to 11 are permitted for the CP in racks 0 to 3

(connected by IM 360/361). 
Proceed as in the sections dealing with setup and

wiring, described in detail in /1/.

Note
The CP cannot be used in an extension rack that is connected via the IM 365! Reason: The required

communication bus is not connected to the extension rack via the IM 365.

3. Connect the CP to the power supply.

Follow the steps as described in detail in /1/ when

wiring between the power supply and the CPU.

S

The CPU, CP and IM (if one exists) must be connected to the same power supply.

S

Only wire up the S7-300 / C7-300 with the power switched off!

4. Attach the CP to Industrial Ethernet.

5. The remaining steps in commissioning involve

downloading the configuration data.

To download the configuration, you can connect

the PG as follows:

S

via MPI

S

via Industrial Ethernet
For further details, refer to the general Part A of

this manual:
− addressing the first time (IP address

assignment / node initialization);

− downloading the defined configuration

The PG/PC requires a LAN attachment, for

example via a CP 1613 or CP 1411 and must have

the necessary software (for example the S7-1613

package or SOFTNET IE). The TCP/IP protocol

must be installed. The protocol used must then be

applied to the S7ONLINE access point.

6. User diagnostics for commissioning and to

analyze problems.
