Alarms, events, and history are made available to MQTT Transmission to be published as immutable Record objects to an MQTT server.  Typically these would be received by the MQTT Engine and MQTT Recorder modules running on a central Ignition Gateway and inserted into a database for later use or to be made available to other third party systems.

Common File Exchange File (CFX) can also be used for these record data.
