  • Thread-topic: Sparkplug - Historic Data flag query

Hi,

 

We have implemented the MQTT sparkplug protocol on our controllers and it is running smoothly.

 

Presently, we have a customer who is looking for the “Historical Data” flag in sparkplug.

 

Our earlier implementation of Sparkplug protocol did not use the Historical Data.

 

We wanted to understand how the Historical Data flag is to used.

 

Can this be given as user selectable and set as True as False while configuring the topics?

 

Or do we need to check the controller connection status and update this flag in the Payload as per the connection status?

 

Thanks,

Vimal
