To view record data which includes ROC alarms, events, and history data you must have MQTT Transmission installed on the instance with the EFM Emerson ROC driver.  In addition, the following must be set up.

• The EFM Emerson ROC module must have a Sparkplug Group ID, Edge Node ID, and Device ID specified in the device configuration
• MQTT Transmission must be installed in the same Ignition instance as the EFM Emerson ROC driver
• MQTT Transmission must have a Sparkplug edge node configured with the same Group ID, Edge Node ID, and Device ID that is specified in the Emerson ROC device configuration
• MQTT Transmission must be reporting to an MQTT server
• MQTT Engine must be installed in a central Ignition gateway and it must be connected to the same MQTT server MQTT Transmission is reporting to
• MQTT Recorder must be installed on the same Ignition gateway that MQTT Engine is installed on.
• MQTT Recorder must be configured with a SQL database.
• The Alarm, Event, and/or History poll rates in the Emerson ROC driver device configuration must be greater than zero depending on which data you wish to collect.

When all of these conditions are met, alarm, event, and/or history data will be collected, published, and stored via MQTT Recorder in the configured database.
