I am trying to display a message that resides in a OPC tag as part of an alarm element. I have tried to bind to the Label property and Notes without any success. The best I have been able to achieve so far is getting my OPC tag path to display as a STRING using UDT parameters, but unable to pull the actual value from the OPC tag.

I should have the ability to bind to a OPC tag value here, correct?  
Syntax issue?

Also…i am trying to set this up as part of a UDT. UDT has two element: .alarm and . description.  
.alarm is a boolean…true when alarm active  
.description contains the alarm description to be displayed.

Image below references a direct tag value. Ideally using UDT parameters for referencing.

Have you tried adding `.value` at the end? `.value` is used to get the value of a tag. Assuming your OPC path you want to bind is a string type tag.
