Dear Binuxx,

I am using s7-315-2DP CPUS and CP343-1 With each CPU

Software redundancy is established and working fine.

At SCADA (WinCC v7.3) , I run redundancy wizard.

from two CPs, two ehernet connections are going to ethernet switch and one connection from switch to SCADA station on LAN Port.

When CPU Changeovers its master to standby status, at scada end also it is working ok when both CP connections are ok.

I want to swich cpu status, when one of the CP connection to ethernet switch will be disconnected.

right now, SCADA station can not recognise this cable break condition.

How to resolve.

please help.

Thanks,

Damayanti Bhapkar
