[?]: double bus with siemens pcs7 and WinCC

Post by XMAS »

Dear All,

'Have been struggling with double bus implementation on the process bus side on a PCS7 controller and client server network. :( :!:
The changeover works but the WinCC driver recognizes a break...and both servers show a disconnection before the system recovers on the second bus.
The recovery time is 30-45 seconds... :cry:

Any ideas or workarounds????

Suggestions welcome!!

Regards
