Within MQTT Transmission, a record is a collection of tags under an Ignition folder which are treated as a single entity and published on demand. They are usually used for, but not restricted to, sending flow computer records such as events, alarms and history data.
Records are published via an MQTT client using a Sparkplug-like topic format with a JSON payload.
Records received at MQTT Engine are passed to MQTT Recorder which automatically generates database tables and populates the rows within the tables with records as they are received.
This tutorial shows how to configure the MQTT modules to generate and publish records to be stored in an MySQL database.
Install the four MQTT modules listed in the pre-requisites onto your Ignition system following the Cirrus Link Module Installation guide
Follow the Ignition Connecting to MySQL guide to configure a database connection to your SQL database.
