Hi

I am using WinCC 7.5 SP2 UPD 12, and I am trying to connect to S7-PLCSIM Advanced v4.0 

But I am not able to make the connection to the simulation. 

See attatched picture. 

I guess I am wrong in my Set PG/PC Interface settings??

Hi!

As I have seen in other cases you could be experiencing a compatibility problem between your software version and the PLCSim version. 

You can check this issue using Siemens compatibility tool.

Thanks for your reply serendipity0. 

I did not manage to get the simulaiton to work with PLCSIM Advanced, but out of the sky, suddenly it works with PLCSIM v17.
