avez-vous  trouvé une solution pour résoudre ce problème ???

Hello,

I have a question about using WINCC.

I configured 2 PLC and 1 HMIi PC

One is a MASTER PLC , Other one is a SLAVE PLC

HMI displays MASTER PLC data

SLAVE PLC is Collect data such as master PLC, Cuz, Redundancy communication

In case of communication error, the HMI connection(tag management) can be changed instead of the data exchange between PLCs ?

(Please refer to the picture below)

Split from Automatic Change 'Connection' of WinCC Tag management.
