A versatile messaging protocol for smooth communication

MQTT - Your flexible messaging protocol

MQTT is an OASIS standard messaging protocol for the Internet of Things (IoT). It is designed as an extremely lightweight publish/subscribe messaging transport that is ideal for connecting remote devices with a small code footprint and minimal network bandwidth. MQTT today is used in a wide variety of industries, such as automotive, manufacturing, telecommunications, oil and gas, etc.


How does MQTT work?

In MQTT, clients can either publish messages to a topic or subscribe to a topic to receive messages. 

The messages are routed to any clients that have subscribed to that topic by a broker, which acts as a central hub in the communication. This enables decoupled and scalable communication between clients.


Embedded interfaces supporting MQTT

Get into industrial IoT with the Anybus CompactCom 40-series, supporting both OPC UA and MQTT.

Thanks to the support for IIoT functions, device manufacturers and machine builders who use Anybus CompactCom can make their data available to IT systems and IoT software in an easy and secure way.


Standalone gateways

The Anybus IoT X-Gateways and Communicators allows you to seamlessly interconnect legacy devices and PLC control systems between industrial networks and OPC UA/MQTT. 

Networks and devices can remain secure and isolated with data flow being controlled from an independent device. 


MQTT for remote data acquisition

The Ewon Flexy remote data gateway is a perfect device for transmitting live data via MQTT from a variety of smart devices (such as meters, sensors, etc.) to any IoT platform. Easily use an Ewon Flexy gateway as an MQTT client and communicate with any distant MQTT broker.
