Hello, I'm facing the same situation but with V13.

I have a simple project on Wincc7.4, which is animate a red ball, when I have the bit activated it turn's green, and I'm trying to simulate him on TIA PORTAL V13 using the S7-PLCSIM. The PLC that i am using is a S7-1500 as shown on the image.

The TIA PORTAL programm is working correctly with s7-PLCSIM, but PLCSIM is not working together with wincc7.4.

In Tag Management I have the configurations that you can see on the images, and in PG/PC settings i have these.

What I need more? It's shows me green on Tag Management but it doesn't work.

Thank you, wainting for your answer

Hello sorry for the late answer.

I solved the problem.

The simulator and the PLCSIM didn't had the same IP address.
