Is there a way for me to create a new UDT instance from a script triggered by an event in Perspective? I have used system.tag.write... to create standard tags in the past, but can't seem to use it for UDTs. Thanks for the help!

You’ll want to use [system.tag.configure](https://docs.inductiveautomation.com/display/DOC81/system.tag.configure) with a _tagType_ of “UdtInstance” and a _tagId_ that is the name of your UDT. There’s examples in the docs.
