TF6701 | TwinCAT 3 IoT Communication (MQTT)

TwinCAT 3 IoT Communication provides basic functionalities in the form of PLC libraries for sending and receiving data via the so-called MQ Telemetry Transport (MQTT) protocol.

By enabling the transmission and receipt of publisher/subscriber-based MQTT messages directly from the controller, this function makes easy data communication between diverse devices possible. TLS is available to secure the transport channel, which enables encryption of the data packets and authentication at the Message Broker. MQTT is an open, standardized communication protocol that is becoming increasingly popular for fast and efficient data transmission applications due to its low overhead. Many IT providers, but particularly those in the cloud computing field, provide access to their services via this protocol.
