Tag historian timestamp source (Ignition 8.1.5)


I am receiving data from a sensor via MQTT. The sensor sends 10 diferent inputs along with a “Time” tag indicating the original time that the sensor read this inputs.

When the sensor loses conection it stores the readings in a buffer and sends it again when the conection is restablished.

The issue is that this old readings are stored in the tag historian with the system timestamp instead of the time the reading was recorded by the sensor.

Can I change the settings of my tags to store on the tag historian with the value of this “Time” tag instead of the system timestamp?


I have exactly the same issue. Do you (or anyone else) sorted out?

Thanks, Elio
