Referencing a tag property in another property within the same tag

I wanna reference the property “Label” in the the property PB_OPCtag. I tried tag({PathToTag}+’.Label’) but that didn’t work… Can this be accomplished?

No can do sorry. The only thing you can do is to write the value via a script

IF you don’t have a restriction on having to use this specific tag, you can probably do a similar thing by using an UDT with “PB_OPCTag” beng a string tag with it’s value source deriving from an expression.
Otherwise, you’ll have to do as @nminchin said.

arent there also parameters in udts? i suppose you could ref those multiple times.
