Hello again.

Thanks for the reply, but my problem is different.

The user I'm using is a administrator.

I get the same error and I have to recreate OPC UA configuration' function of the 'Communication Settings' program.

I am not allowed to do it because I find him disabled, but I think the problem is different.

In the Station Configuration I find the Stationmanager in error and if I open the Simatic NET Configuation Information Service, the diagnostic says: "Could not enstablish the connection to the SIMATIC NET Configuration Server".

I don't know how to solve the problem.

Does anybody found a solution for this?

Thanks in advance.
