Hi all!
Suddenly, I can not connect any PC HMI application to S7-1200 (6ES7 214-1AG31-0XB0) via Ethernet.
Both HMIs, WinCC Advanced V11 SP2, and WinCC Flexible 2008 SP2
reports an error:
"missing user rights to write into registry"
All the time PLC is online, visible, working fine.
Someone knows what is going on?
