Unitronics, a leader in the programmable logic controller arena, features MQTT in the latest release of UniStream, the award-winning PLC+HMI series.

Lightweight, simple, MQTT (Message Queueing Telemetry Transport) runs over TCP/IP, based on a publish- subscribe structure.

UniStream supports MQTT as a ‘client’ that can both publish and subscribe to messages.

UniStream can:

  • Publish data to a defined Broker according to a configured Topic. For example, the Topic may be Machine; the messages can include application data such as temperature or pressure. UniStream can publish periodically, according to a time period set in the configuration or a periodically, according to event.
  • Receive data from a defined Broker on a defined Topic, to which UniStream is subscribed.

Facing Industry 4.0

In addition to MQTT, UniStream series programmable controllers support a range of communication channels and protocols that supply the connectivity required by Industry 4.0 including SQL, built-in webserver that enables the controller to be accessed via any browser, and more.

About UniStream

The rich feature range of UniStream includes auto-tuned PID, datalogging, data tables and Recipes, data sampling displayed via built-in Trends and Gauges, Alarms, multi-level passwords, multi-language support including Asian languages, and communications with any device via CANopen, CAN Layer2, MODBUS,  EtherNetIP, and more.

All-in-One UniLogic software slashes setup and programming time. The built-in Design and Re-Use paradigm enables you to build Ladder and C functions, design HMI screens, and create Web pages in multiple languages, and save it all in a Library to reuse in other projects.
