Hi all,

System overwiev:

• PCS7 V9.1 SP2
• OS Redundant pair + 4 OS Clients, Redundant s7-410, PDM, Maintenance Standard.

If I open the faceplate of an analog input with HART on OS Client I can see internal licensing error and the buttoncall Simatic PDMis grayed - screenshot attached.

Do we miss some component or licence? Any idea how can I solve the problem?

Thanks in advance!

Kamil
