Overview

Travis Cox installs and configures the MQTT Engine Module for Ignition. The module allows us to connect to an MQTT server and subscribe to data.  It will automatically discover all the data that’s there and turn that data into usable tags in Ignition that you can add configuration to.

By default, when you install the MQTT Engine Module, there’s a setting that blocks the device tag writes. Travis Cox shows how to allow outbound tag writes using the MQTT Engine Module so you can write down to a tag in the PLC on the other side.

Travis Cox discusses the primary host ID setting for the MQTT Engine and MQTT Transmission Module. The primary host ID identifies the main application that is receiving the MQTT data to guarantee that data doesn’t get lost and gets delivered to the desired application.

Travis Cox demonstrates how to set up Transport Layer Security (TLS) in the MQTT Distributor, Engine, and Transmission Modules. This is critical for secure and cryptic communication.

Travis Cox shows how to set up the store-and-forward system in both the MQTT Engine Module and the MQTT Transmission Module. Store-and-forward is very critical to applications because if you lose connection to either side, you lose data. This demo is a pure MQTT solution, meaning it will work with…

This video shows the installation and configuration of Ignition and the MQTT Modules within AWS on EC2 instances.
