Set your DataChange type to Always

For infotables, the Data Change / Value will only trigger when the number of rows changes.

Set it Always means the Data Change will fire each time the field is updated, which is what you'll need.

IF the agent is writing the same values at times, you'll need to do some validation if you don't want to use those values.
