Written by Win Worrall | Jan 17, 2019 7:00:00 PM

With the release of Cogent DataHub Version 9, we've expanded the multitude of data sources you can integrate to include IIoT (Industrial Internet of Things) with MQTT (Message Queuing Telemetry Transport) support.

The following short video blog demonstrates step-by-step just how easy it is to configure the DataHub MQTT Client for publishing data from DataHub to any MQTT Broker, as well as, subscribing to data from any MQTT Broker for integration into your systems via DataHub's supported interfaces (such as OPC).

In this video you will learn how to setup the MQTT Client feature of Cogent DataHub V9 for the following functions:

  • Subscribing to data available in an MQTT Broker (which can then easily be integrated with your other systems using DataHub's supported interfaces) - for this example, the data acquired from the MQTT Broker will be written to an OPC Server

  • Publishing data available in Cogent DataHub (an OPC Server, for this example) to an MQTT Broker 

Just to summarize, in this video, I've shown you:

  1. How to configure an MQTT Client Subscription (pulling data) for an MQTT Broker.
  2. How to configure an MQTT Client publish (pushing data) to an MQTT Broker.

Don't forget to read our new features blog post to learn about the other great features in DataHub V9 or visit the Cogent DataHub website for full details of the release.
