FT SE V10 - User input - Parameter Passing?


I am trying to have one screen that has one trend, that I can have an operator select what tag to trend.

IE I am trending a bit shift, a photo eye and a solenoid that all have a common number (Let's say 123). I want the operator to open the screen, Punch in 123, and see those 3 attributes live trending. So PE 123/ SV 123/ BSL 123 showing on the trend.

Initially, I thought parameter passing was the rabbit hole I was going down but I got a couple of inches deep and gotta hint this might not be the best way.

Another idea I had was to use a global object and have the value be an HMI tag the operator writes into.

I know this can't be the first time this has been done so I am trying to not reinvent the wheel.
