Hello,
I am facing a communication problem.There is a loss of communication between S7-400 Plc and OS Server (WinCC).When this problem occurs all the scada screens are getting blured. It happens regulary, sometimes 2 or 3 times in a day.The way we handle the problem is by deactivating the WinCC and Activating the winCC on server, but this is a temporary solution please help me find a permanent solution.Also the communication between PLC and OS Server is through Ethernet.

Regards,
gaus
