Bind EngHigh & EngLow in UDT to PLC tag

Ignition
1

I’m trying to bind the EngHigh & EngLow numeric properties of a tag inside a UDT definition but can’t seem to figure out the right syntax. The only thing that seems to work is a numeric literal, and that hardly seems like a binding.

Using Ignition 8.1.7

I’m fairly certain you can’t bind a tag to those properties dynamically, but you can set up a script to write to them.

ok, that explains that then, thank you

Yep one way would be to write a Tag value change script on your MaxValue tag. So whenever the value of your MaxValue changes it should write to the engHigh of your tag.
