Need help. For months now S7 communications is working perfectly, but now for some reason all the S7 WRITE nodes status is connected, but no actions anymore, even output show no message at all. All my READ nodes al still working well. Anybody has an idea what can be wrong here?

This issue has been solved, and was caused by the S7-PLC itself. I use a S7-200 PC with ethernet connection. Lately I bought a new one with updated firmware from Amsamotion and now the communication problems have vanished. So I can safely say that the problems were due to the plc I used to have.
