Tip

MQTT Transmission 4.0.16 through 4.0.22 support the propagation of alarm events from the Edge to MQTT Engine on the Central Gateway to be inserted in the Ignition Alarm Journal but do not support the remote acknowledgment of those alarms

MQTT Transmission 4.0.23 and newer support the propagation of alarm events from the Edge to MQTT Engine on the Central Gateway to be inserted in the Ignition Alarm Journal along with acknowledgements from the Central Gateway back to the Edge

Review the Alarm Event Propagation document for system configuration details including the changes needed to the data/ignition.conf file and MQTT Engine
