Hello norimane;

As a beginner in automation, your next step should be to learn how to use the available tools of this forum.

For example, using the Site Explorer search box at the right of this page, looking for "WinCC v7.3 and PLCSim", you would have been pointed to this FAQ:

How can you link WinCC to S7 PLCSIM?

The FAQ applies to an installation of both softwares on the same computer. Try the proposed solution, tell us if it resolves your issue (it was designed for WinCC v6.x). 

Hope this helps,

Daniel Chartier

hello dchartier.

 can you please help me to resolve this problem

Hello norimane;

Please add screenshots of the error messages you recieve, they can be very helpful when we try to understand your problems.

By the way, what communication link are you trying to establish between your WinCC application and PLCSim? MPI? Industrial Ethernet? Are both softwares installed on the same computer?

In the meantime, follow this thread, specilly the posts by our friend Ammy:

[SOLVED] - PLCSIM 5.4 and Wincc with Ethernet.

Hope this helps,

Hello norimane;

WinCC uses other mechanisms to diagnose the connection status than the lifebit check, look at the manual proposed earlier on WincC v7.3 Communication, chapter 18, Channel Diagnostics.

For example, look for the section on "Status - Logical Connections" Function for a basic diagnostic;or the section on Diagnosis of the "SIMATIC S7 Protocol Suite" Channel.

Hope this helps,
