In the tag creation for a UDT when creating tags (OPC, Expression, etc.) you can put a binding on the tag group.

In that binding is all expression language available?  
I want the tag group to change depending on a tag within the UDT. I want to check using an if statement, if a tag in the UDT is true then use this tag group, if false use this other tag group.

Is this possible?

Expressions can’t be used for tag group. You can create a UDT parameter with tag group name, which can be referenced in member tags. Then you can write to the parameter with a tag change script.
