Tag Change Caller Information

Ignition
1

I’m working on a Perspective project in Gateway 8.0.12

I have a tag whose value is being updated without my program explicitly writing to it, so I suspect that another program with access to the tag is making the change.

When a tag value is changed, is it possible to get information about the caller (the entity making the change)? Any available information would help in debugging - project name, session ID, user, etc.

Thanks in advance.

Have you tried the audit subsystem?

That’s what I’m looking for. Thanks for the help!
