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)

Instructions:
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.

Note:
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.
