I am working in a project that the customer wants to change Monitoring to Wincc.

The Automation side is based on Siemens S7-400H and since the logic has been written with FBD and STL, I can not use PCS7 faceplate on wincc.

So I managed to define 10 picture window in @1001.PDL and write 2 C-Script to call some Faceplate for different Objects ( PUMP ). The first function open main faceplate and second one open another picture in main faceplate.

So far so good , But in runtime after a while these actions and all other actions does not working. I attached log files and also C-Script functions.

I would be grateful if someone help me to solve this problem and also suggest another way to show these faceplates for several objects.

P.S : Can I use TOPxx picture windows instead of manually inserted?

thank you
