Sending ROC Alarms to a Central Ignition Gateway

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
      
      

Overview:

The EFM Emerson ROC module is capable of getting alarm events from a ROC device based on a specified polling rate.  With MQTT Transmission, these alarms can be published as Sparkplug records to an MQTT server.  Any client subscribed on Sparkplug RECORD messages can receive these objects.  In addition, MQTT Engine when combined with MQTT Recorder can also receive these messages and store these objects in a configured Ignition database.  The following drawing shows the general architecture used to do this.  This tutorial outlines the process of getting alarms to the central Ignition gateway.

Sending ROC Alarms to a Central Ignition Gateway:

We must configure a total of 5 Cirrus Link modules on two different Ignition gateways to get Alarm data flowing from an Emerson ROC device to a central database.  These are:

• Central Ignition Gateway
  
  • MQTT Distributor
  • MQTT Engine
  • MQTT Recorder
• Remote/Edge Ignition Gateway
  
  • MQTT Transmission
  • EFM Emerson ROC

We'll cover the configuration of each of these by each Ignition gateway that they'll be set up on.
