Adding the PROFINET master

The PROFINET master is added in the TwinCAT System Manager in the same way as the PROFINET slave. You can then find all connected slaves via the master. The following section illustrates how to add a PROFINET master in TwinCAT.

Prerequisites for this step:

  • TwinCAT must be in Config mode.
  • A selected target system (in this sample it is the Embedded PC CX5020-M930)

Add a PROFINET master as follows:
