I created a tag triggered schedule and pointed a udt tag, but the schedule fires on every cycle, even when the tag hasn't changed.

I've already tried creating an individual tag pointing to the same PLC tag, changing the mode and acquisition rate but nothing worked.

This happens on Wincc Unified v19 and v20 update 2.

Does anyone know what could be happening?

It worked, thank you!

These settings are located in Runtime Settings -> Tag settings -> Tag notification behavior.
