History Export via MQTT in the Tridium Jace

IMPORTANT: The base query will generate the json for all the histories at the interval set in the Base Query: Publish Interval slot (default is 24hrs). If the RelativeJsonSchema out slot is connected to engineCycleMessageQueue followed by MQTT string publish point, the full history export will generate and be published to MQTT every publish interval (even if the trigger to generate json is not connected). This repeated history export can overwhelm communication and ingestion of the data stream. It is required that controls are put in place to prevent history exporting unless required, via:

1. Disabling the RelativeJsonSchema via the Enabled slot

2. Deleting the link between out slot and engineCycleMessageQueue, and only linking when a history export is required.
