Note
The topology of this example shows MQTT Distributor, MQTT Engine, Record Store, and MQTT Transmission all running in the same Ignition instance.  This is done for simplicity of the tutorial, but this isn't required or even intended to be a real use case.  In a more realistic scenario MQTT Transmission and MQTT Engine would be located on separate machines.


Step 1: Install the MQTT modules

Install the four MQTT modules listed in the pre-requisites onto your Ignition system following the Cirrus Link Module Installation guide

Step 2: Configure a database connection

Follow the Ignition Connecting to MySQL guide to configure a database connection to your SQL database.
