In this part of the Wise SCADA training series, we cover MQTT communication in detail, which is widely used in industrial automation and IoT-based SCADA projects.

In this lesson, you will learn how to use the Wise SCADA MQTT Client to publish Tag values to an MQTT Broker and subscribe to data coming from the Broker step by step.

All critical MQTT parameters are explained through real-world scenarios, including connection settings, security options, Publisher–Subscriber logic, and data transmission methods.
