Hi Suman,
Currently there is no PCo mechanism to detect which tag has changed value and assign that tagname and value to a notification output. The Notification Trigger type = Always will fire the notification if any of the tags in the Agent instance subscription items changes value, and will pass whatever tags and values are defined in the Notification Output to the destination.
What is your use case for having to dynamically detect the tag vs setting up specific notifications for the tag change?
Regards, Steve
