PLC MQTT Communication Using TIA Portal, Mosquitto and Node-RED

In the industrial environment, efficient and reliable communication protocols ensure seamless connectivity and data exchange between various devices and systems. One such protocol that has gained widespread popularity is MQTT (Message Queuing Telemetry Transport). MQTT operates on a publish/subscribe model, where devices are connected to a central hub known as a broker. This makes MQTT particularly suitable for the industrial setting, where multiple devices need to exchange data without direct communication. Instead, they publish data on specific topics on the broker, and any interested recipients subscribe to those topics, receiving the relevant data. MQTT's scalable nature and ease of implementation make it an ideal choice for industrial automation scenarios.
