MQTT Transmission is connected to the MQTT Server and as a result MQTT Engine is receiving tag change events.  In addition, because an EFM Emerson ROC device has been created and configured with the same Sparkplug Group ID, Edge Node ID, and Device ID, events will also be pushed to the MQTT server as Sparkplug RECORD objects.  When event are discovered by the EFM Emerson ROC driver, they will be published to the MQTT server, consumed by MQTT Engine, passed on to MQTT Recorder, and then inserted into the specified database.  Below is an view of some event records using a third party database viewing tool.
