How do you configure a PC station as DP slave for connecting an S7 station (as DP master) for the SIMATIC NET OPC server with the SIMATIC NET PC software?

  • Entry
  • Associated product(s)

In this example, a CP5611 is used for the communication via the OPC server as DP slave with an S7 station as DP master on the PROFIBUS.

The procedure described here also applies for communication processors CP5511, CP5512 and CP5621.

General information:
You can choose between two different configuration tools:

  • NCM PC:
    NCM PC is supplied with the SIMATIC NET CD and permits you to create PC projects and open STEP 7 projects. However, it is not possible to use this software to edit the S7 blocks in the STEP 7 project. 
  • STEP 7:
    STEP 7 is a separate software package and permits you to create S7-400, S7-300 and PC projects. It is possible to use this software to edit the S7 blocks.
The requirement is that STEP 7 is installed and that the DP master is already configured (for example, STEP 7 project with the configuration of an S7 station). If the DP master is also a PC station, then the configuration of the PC station as DP slave can also be made with NCM PC.

Please follow the instructions below for configuring the PC station.
