Hi there,

I have a UDT with 4 tags inside. One of them is Id. This UDT is used at multiple locations in our Model. Is there a way to search Id value of all instances in entire model for that UDT?

I am hoping for a script as I need to utilize for other purposes.

Thanks

You can do a recursive `system.tag.browse` and filter on the udt type, then use the paths from the results to read the id.  
Though I wouldn't recommend doing this for all use cases, as it can take a while if you have a lot of tags.

The tag report tool is an option as well, although, `system.tag.browse` seems to be a lot quicker, so depends on when/where you run this search.
