How do I use JSON with Ignition MQTT Engine?

Tech Note 5119, “Using Ignition MQTT Engine with Maple Systems HMIs” provides set-by-step instructions on how to setup the Ignition MQTT Engine, custom topics, and JSON payloads.

The Tech Note assumes that the user already has the Ignition platform installed along with the MQTT Engine and MQTT Distributor (or other MQTT Server infrastructure). For instructions on how to setup MQTT publishing on a Maple Systems HMI, see Tech Note 5111, “MQTT Set-up.”
