I'm creating some scripts to dynamically update some Value objects on a display. But there are cases when some of the objects may not have a tag defined for the unit I'm referencing. Is there a way to set a Value object's tag property to null so that it doesn't display anything?
I have a work around where I created a Dummy tag on the PI server and set it to that. It's a lab tag that I set to read "No Alias Configured" and that workaround works OK, but I'd like a cleaner solution that doesn't rely on a special tag that I have to ensure no one changes, deletes, etc.
P.S. I hope I'm not wearing out my welcome on the forum, I appreciate all the feedback from the members...just have a lot of questions as I'm digging deeper into my current project (my first one, as you can probably tell, and I'm the only PI guy at my company!).
