About MQTT

MQTT (Message Queuing Telemetry Transport) is a cross-industry IoT communication protocol standard used for machine-to-machine (M2M) communication and interoperability between IT systems and sensors.

The protocol is based on TCP/IP and follows a publish-subscribe architecture. A client (publisher) sends data for a specific topic to the broker, which then passes the data on to the other clients (subscribers) that subscribe to that topic. MQTT allows fast and efficient data transfer, made possible by the small protocol header and transmission not requiring periodic requests.  

Selection Guide

All the Ethernet ports support MQTT. One port can handle the data transmission of multiple MQTT clients configured in the real-time application. Each MQTT client requires a runtime license. MQTT support is available with MATLAB^® R2020b and later.  

The following native implementations are available:

Speedgoat real-time target machines are equipped with onboard Ethernet controllers that support MQTT. In addition, MQTT is compatible with the following Ethernet I/O modules:

Most of the Ethernet interfaces (both onboard and on I/O modules) also support various protocols, such as Modbus TCP, DNP3, OPC UA, EtherCAT Master, TCP/IP, Real-time UDP, PTP, and XCP over Ethernet.
