Publishing Files with Transmission

Prerequisites:

• Installing the Java Runtime Environment
• Installing Ignition on an 'host/backend' system
  • This must be a 'full version' of Ignition (i.e. not Ignition Edge)
  • Installing the following MQTT Modules
    • MQTT Distributor
      • v4.0.X if using Ignition 8.0.x
    •  MQTT Engine
      • v4.0.X if using Ignition 8.0.x
• Installing Ignition on an 'edge' system
  • This can be a 'full version' of Ignition or Ignition Edge
  •  Installing the following MQTT Modules
    •  MQTT Transmission
      
      • v4.0.X if using Ignition 8.0.x

Overview:

Transmission is an MQTT module for Ignition that can publish files using MQTT Sparkplug. This tutorial shows how to configure MQTT Transmission to publish files from one Ignition system to another. Files are transferred using Sparkplug over MQTT. The files which get transferred and when they get transferred can be configured in a number of different ways.

Publishing files with Transmission:

As noted in the prerequisites, you should have two Ignition systems installed at this point.

• A full version of Ignition with MQTT Distributor and MQTT Engine installed
• A full version of Ignition or Ignition Edge with  MQTT Transmission installed

Begin by configuring the host system with MQTT Engine. Set the following:

• MQTT Engine Settings → General Tab
