WinCC Unified on comfort panels:
I receive from outside the name of the data set I have to setup the equipment. 
I use the scheduling when the trigger rising up of the following sys function following a sequence because running at the same time get faulted:
1.LoadAndWriteParameterSet Works fine
2.GetParameterSetID Works fine
3.GetParameterSetName prompt me back an error!

what is driving me crazy is that the same logic is developed in 2 different machine, one is working (even the function takes about 5 secondis to prompt me back the result) and the 2nd goes faulted. 
also changing the order of the sequence doesn't change the result
tested both script or function as menue of function, same issue
same firmware release
same software release
same TIA Portal release 20 upd3

Any suggestion for me?

Split from Get ParameterSetName from ParameterSetControl.

Hello pigroplc

Have you checked the system messages, which are displayed in the alarm control in case of an error?

Best regards, Costanza

Just for feedback could be useful for someone else:
issue fixed upgrading the panel firmware from V20.00.00.02 to V20.00.00.04
Now is working flawless.
Thank you.
