This webinar introduces MQTT-based data acquisition and explains why MQTT is becoming a go-to messaging protocol for Industrial IoT and remote monitoring. It breaks down MQTT’s publish/subscribe model in plain terms—showing how devices publish I/O status to topic “channels,” how users or applications subscribe to those topics, and how commands can be sent back to outputs through the same broker. The video then walks through configuring an ICP DAS USA MQTT I/O module (broker settings, client ID/alias, topic naming, publish intervals, QoS levels, and security/authentication), and demonstrates how the module can be monitored and controlled through its built-in web interface or through external IoT/SCADA platforms. Finally, it presents a factory automation example where multiple production lines publish counter data, a controller evaluates totals with simple logic, and stop-production commands are issued automatically—showing how MQTT can support scalable, low-bandwidth monitoring and control across industrial networks.
