Serial communication in tags

I have an application where I’m using a tag event script to read from a serial port at a set frequency.

I want to have a localized Ignition gateway continuously retrieve that information and be accessible for other application via OPC UA. And I have this working in a trial install.

My question is, do the realtime tags run as long as the Gateway is running, or does it need Vision/Perspective open for the tags to execute?

Tag Event Scripts run independent of any UI. So no, a Perspective or Vision client is not required.
