I have tried with UDT parameters, and it works if I change the parameter manually.  
But I cant bind parameter to a tag. It works only one way - when I change parameter,  
the tag connected to that parameter updates. But not the other way.

Searching in the forums I have found similar request and it looks like 10 years ago that was not possible. Has that changed since ?

> Hi Colby, You’re right, this data will not change. I just felt a bit uncomfortable with the redundancy, but it’s not a big deal anyway. I have not come yet with the need to pass variable data to the UDT, but I guess it might be very useful to have it. Thank you!
