I have a question about parameter files in Factory Talk View Machine Edition. Can you pass placeholders in a parameter file like you can with a parameter list? This would let me not stack a bunch of buttons on top of each other. I hope I have the terminology right, but I'm calling a "placeholder" #1 etc.
For instance with a parameter list you can call a pop-up and pass multiple parameters including placeholders established when the main display was called:
{#2.PT_31X11},{#1\PT_31X11_Tag},{#1\PT_31X11_Units},{#1\PT_31X11_Desc},{X#1}
Because #2 in the current display is {::[PLC]PROGRAM:V30100},
In the pop-up, #1 is now {::[PLC]PROGRAM:V30100.PT_31X11}
I'm trying to do something similar in a parameter file in the line: #150={#2.CH_15X10}, but it doesn't seem to work. Does anyone know if this is possible, and how to make it work?
