First Steps with MQTT

MQTT is how machine data reaches SCADA systems, historians and cloud platforms. This course explains how publish/subscribe works, how to install and secure an Eclipse Mosquitto broker, and how to connect Arduino, ESP32 and Raspberry PLCs as MQTT clients.

What you will be able to do

• Explain topics, QoS, retained messages and last will, and design a topic structure.
• Install a Mosquitto broker on a PLC and protect it with authentication.
• Publish and subscribe from Arduino and ESP32 PLCs over Ethernet and Wi-Fi.
• Connect a Raspberry PLC as an MQTT client.

Who it is for

Integrators and engineers who bring PLC data to dashboards, SCADA or the cloud. Basic programming knowledge is enough.
