Is it possible to subscribe to certain UDT types with Event Streams?
What do you mean by subscribe to a UDT?
I think “subscribe” is a bad term. I mean set up a Tag Event source, but I’m wondering if there’s a way to only have that listen for tag changes of specific UDT types without manually adding every single UDT instance path to the source. Basically looking to see if event streams can replace transaction groups for data logging, but with support for UDTs.
Are all your instances mostly grouped together or are they scattered around? You might be able to pull something off with Gateway Tag Change events and using wildcards in the configured paths.
This is just a hypothetical, but they’d be scattered around. For example, if you had a Pump/Motor UDT and wanted to execute a script whenever those changed.
