I cant force values to my PLC with Compact HMI800
Hello, iam experimenting with COMPACT HMI800 and
i am trying to force values to my PLC variables (i checked the controllable option).
I can see the changes in Compact HMI800 when i force values from codesys but not the other way around. What do i do wrong? Also there two warning symbols a triangle with an "x" and another one, next to my variables in the Compact HMI800 when i try to force a value.
