Unable to Trace Source of Tag Write for Memory Tag

Ignition
,
1

Hi all,
I'm trying to trace where a Memory Tag is being written from in my Ignition project, but haven't been able to locate the source of the write.

What I’ve Tried:

  1. Checked Tag Diagnostics & Reference Log
    Reference log shows many Perspective subscriptions across multiple views.
    No indication of any write operation — only reads/subscriptions.
  2. Verified Tag Properties It’s a Memory Tag — not OPC, not bound to an expression — so must be written via scripting or user action.
  3. Also manually tried Tools → Find/Replace, but didn’t locate any clear write reference.
  4. Checked Gateway scripts: timer scripts, tag change scripts.
  5. Checked any tag change from any UDT, not checked all UDT's but checked few related to this and found no tag change script.
    Any insights, ideas, or suggestions would be much appreciated! Thank you!

Rename the tag, watch the logs till something fails...
You could have a remote OPC-UA client writing to the tag also.
