How to translate terminal SELECTED of AC450 DB elements using PP Library ?
Dear AC450 experts,
I am working on AC450 logic translation to AC800M, which contains a lot of DB terminals :SELECTED. Is there any reliable solution how to get information into the logic that object is selected by operator at HMI with using Pulp&Paper library?
Possible way could be Property writer in graphic elements, but PP lib functions are locked therefore it is impossible to add any output terminal SELECTED to PP AOC, DOC, etc.
I will appreciate any idea, thanks.

Are you talking about cases where SELECTED is connected to a MOVE statement and then written to either blocked or man mode? For these cases it is common to replace DIC/AIC with DOC01/AOC01 from PPLib, and simply leave them in Man mode all the time.

Just a thought:
If you intend to add terminals / functionality to a locked / closed Library, you may need to embed the PP function into a new project specific function. In the new project specific function you can then add the extra terminals / functionality.
I hope the above may help you.
