MQTT Transmission Module Overview

The MQTT Transmission Module enables Ignition to publish tag data to MQTT servers using the Sparkplug specification. By monitoring configured Ignition tags and publishing updates as Sparkplug messages, MQTT Transmission provides a scalable and efficient method for distributing industrial data to MQTT-based applications and systems.

MQTT Transmission also supports remote tag writes through Sparkplug command messages, enabling bidirectional communication between Ignition and MQTT-connected devices, applications, and enterprise systems.
