@Archie,
I think its a long shot, but if the control has no region named PLC Related Properties, it is as simple as copying it out of another control and dropping it into the other control??? I'm guessing - no.
Update:
What's the harm in trying? Well, I got 6 errors just adding the region as-is...
Of course, I have no clue what to do with it.
Update again:
Well, I found another region, "Subscribing and PLC data receiving". Now, I'm down to one error.
Final Update:
Not knowing at all what I am doing, further messing made matters worse. I stopped here. Not sure what to do, except just to delete it and bail on the idea.
