As you are likely already aware, Cogent DataHub Version 9 expands the assortment of data sources you can integrate to include IIoT (Industrial Internet of Things) with MQTT (Message Queuing Telemetry Transport) support.  As with its many other supported data sources (such as OPC), DataHub V9 can act as both a "client" and a "server" for MQTT - with a "server" being an MQTT broker.

The following short video blog demonstrates how truly easy it is to configure the DataHub MQTT Broker for acting as a "gateway" between MQTT Clients in your IIoT cloud and other supported interfaces including OPC, DDE, ODBC and many other data sources.

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

  • How to enable the MQTT Broker of Cogent DataHub V9 including specification of the TCP port to be used for connections to the MQTT Broker by an MQTT Client.
  • How to interpret raw MQTT messages from MQTT Clients for parsing into points/items (using user defined message formats for flexibility with any MQTT capable system).
  • How to access MQTT Broker data via other supported DataHub interfaces.



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

  1. How to enable MQTT Broker functionality in Cogent DataHub V9.
  2. How to configure the syntax of MQTT Messages for parsing into data items.
  3. How to access MQTT data from Cogent DataHub V9 using an OPC DA or UA clients.
  4. Other possible ways to bridge MQTT data to other data sources including databases, web pages, Modbus slaves, DDE sources such as Excel or even email/text alerts.

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.

Are you ready to start integrating your process systems with the IIoT cloud?
