Hi everyone,

I am using ignition 8.1.0 and I can’t find a way to bind a tag property to another tag value inside the same UDT, is that possible? I have few ideas on how to with scripting but I would prefer not using them… I tried the referencing like in the picture below but it is not working.

Thanks!  
Alex

It’s not possible at the moment. Your best bet would be to use an expression tag and do it manually.
