Hi,
I’m new to Ignition and still getting my head around how everything fits together.
I’m trying to work out how I can have the functionality of Indirect Tag binding in an expression.
For example, I would like to use the following expression:
"<HTML><B>" + {{Root Container.TankSelectionGroup.AreaSelection.selectedStringValue}/{Root Container.TankSelectionGroup.TankSelection.selectedStringValue}/Temperature/Process Variable}
Where TankSelection and AreaSelection are both drop down menus.
The expression, for instance, should evaluate to something like:
"<HTML><B>"+{Vintage Tank Farm/Tank 560/Temperature/Process Variable}
This expression doesn’t work however as expressions don’t support nested paths. Is there a function or other syntax that I can use to get around this?
Thanks!
Nick
