Hello. I have experience developing on Wonderware and Cimplicity, so Ignition is hard for understanding for me now. My question: i have UDT with some attributes (example: Run and Ready, STATUS). I want to form values for STATUS with help Ready and Run in UDT script. How i can do that? Sorry for my English, I am russian developer 😊

Create STATUS as an Expression Tag, and within its expression, use {[.]Run} and {[.]Ready} tag references. Note that this uses [Ignition’s expression syntax](https://docs.inductiveautomation.com/display/DOC/Expression+Overview+and+Syntax), not scripting.
