Can you use paramaters with binEnc?

Ignition

I have three separate Boolean tags, one for a Running, and 2 for alarms. I need to use these three tags for the state of a pump. If I use a direct tag path for each one it works fine. If I use a parameter in the indirect tag binding it works fine also. But when I try to use binEnc({view.params.TagName}+"/RNG") i get the Error_ExpressionEval. Is this something that can be done? I have tried a couple different syntax and none have worked.

I want to use parameter so I can make it a template to use in 20-30 other locations. Any help is much appreciated.

I assume you are using a UDT? Why not create another tag in your UDT that holds the binEnc. Then bind to that tag instead of trying to do the binEnc on the view side.

To update a UDT you have to redownload the program and I am trying not to take this PLC offline.

Ignition UDTs are independent of PLC UDTs.

Roger that, I didn't even think of UDTs inside of Ignitions.

You can also just move the indirect bindings to three view.custom properties (referencing the view.params.tagpath) and then have the expression with binEnc() point at those properties. That's the best solution for items purely in your UI.
