How can you link WinCC to S7 PLCSIM?

  • Entry
  • Associated product(s)
As from S7-PLCSIM V5.4 (WinCC V6.2) you can select any networked node for setting up a simulation connection.

S7-PLCSIM simulates:

  • The CPU of the node selected
  • All the nodes belong to the CPU
  • The subnet of the node selected

How to parameterize S7-PLCSIM is described in the S7-PLCSIM manual in Entry ID: 36450139.
In WinCC you just have to change the logical device name of your connection to "PLCSIM".
 

No. Procedure
1 Right-click to open the system parameters of your connection under WinCC Explorer > Tag Management > SIMATIC S7 PROTOCOL SUITE > "Connection" and select the "Unit" tab. There you set "Logical device name" to "PLCSIM". You must then close and then restart WinCC.
 


Note:

Do not forget to reset the logical device name after finishing simulation.

Note
Up to S7-PLCSIM V5.3 you could only use a default connection via MPI at address "2". For that you had to create a new connection in WinCC via MPI.
