Ok !

But if I have not 1 pc.  PID - regulator but 40 pcs e.g.

And I want to control them from the same screen calling every PID - regulator with one of 40 buttons.

What to do in this case ?

Should I create 40 pcs. invisible "Picture window" one over another and somehow call them with 40 buttons e.g.

Moreover WinCC assumes 32 layers only, but I need 40 "Picture windows" one over another in the same place of the screen.

Is it possible to only use one "Picture window" with pdl - picture with faceplate instance inside and to control the 40 pcs. of PID - regulator ?

If so, then which Script is required ?

Split from how to link tag prefix in picture window of the faceplate?.
