Dear All,

We are using Siemens WinCC 7.0 SP3 SCADA software. We are using two Redundant SCADA Computers that are communicating with PLC (CP-343 module) via Ethernet. One Ethernet cable from each PC is connected to Cisco Ethernet Switch and one Ethernet cable from the Cisco Switch is connected with CP-343 Siemens Ethernet Module.

The problem is after every 75 hours one PC value become still (Freeze).Only One system values freeze at a time. If i restart the system the problem is resolved. Please help to resolve this problem. Thanks
