Prerequisites

• Installing the Java Runtime Environment
• Installing Ignition
• Installing the following MQTT Modules on two Ignition systems
  
  • Ignition System 1 (Central Ignition Gateway)
    
    • MQTT Distributor
    • MQTT Engine
    • MQTT Recorder
  • Ignition System 2 (Remote/Edge Ignition Gateway)
    
    • MQTT Transmission
    • EFM Emerson ROC driver module
      
      

...

The next step is configuring the EFM Emerson ROC module.  This is done as described in the Emerson ROC Configuration manual.  In going through the basic setup and configuration for Alarm configuration the following steps must be performed:

...

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, alarms will also be pushed to the MQTT server as Sparkplug RECORD objects.  When alarms 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 a view of some alarms using a third party database viewing tool.
