I have a udt memory tag with a default value and have a few instance of this udt. This tag value changes over time. I’d like to default it back.  
Is there a way to do this without changing it on every instance of it?

Thanks.

You could create a script that goes through each of the instances and writes to that value. You could just run this from the script console.

tagList = ["[default]tag1/tagVal", “[default]tag2/tagVal”]  
valueList = [2, 2]  
system.tag.writeBlocking(tagList, valueList)
