Vision 8.1.7  
Example:  
Several Machines that I would like their tags to be Driven off of say running or not.

I would like a UDT for this as making tag groups for each machine is impractical. Is this done in the driven expression using the parameter that is already made for the UDT tags?

UDTs can't do this. You need separate tag groups per machine.
