How to start WinCC RT on another Workstation and get it work
Posted: Sat Oct 01, 2016 6:21 pm
WinCC – project was developed on PC1 and connection to PLC was also made there.
The idea is to make a spare Workstation (WS) with the same IP address.
If the main WS (PC1) is broken then I disconnect it off the Ethernet network, connect PC2 and start WinCC RT on PC2.
WinCC project is single-user and has a following feature. WinCC tags are connected to STEP7 with «Named Connection», but not with «TCP/IP» as normally for the single-user WinCC projects.
After starting WinCC RT on PC2 it doesn’t work, cause «Named Connection» is not established, connection driver “is disconnected”, tag values don't transfer from PLC to PC2 and vice versa.
