In this example, a CP5611 is used to establish the FDL connection with a SIMATIC S5 95-U on the PROFIBUS via the OPC server.

The procedure described here also applies for communication processors CP5613/14 (A2), CP5621 and CP5511/CP5512.

General Information:
The requirement is that one of the two following configuration tools is installed.

  • 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.
