Cogent DataHub is always expanding its wide range of flexible connectivity options between different data sources such as MQTT, OPC UA, OPC DA, ODBC, DDE and so much more.  With the advent of IIoT and its increasing adoption across industries, connectivity to various traditionally non-IIOT data sources via MQTT is key.

If you're not familiar with the concept of a virtual or digital twin, it's the idea of virtual modeling a physical asset or system.  Ultimately, the key motivators for creating digital twins is having the ability to accurately model and predict what will happen with the real-world physical equivalent of that digital twin.  Digital twins are extremely beneficial towards predictive analytics used for pro-active maintenance and process optimization across industries.

In this next installment of our Cogent DataHub Virtual Training series, we will cover step-by-step how to easily connect and push data from OPC data sources to digital twins in the Azure IoT Hub including how to optionally do so through a network DMZ (DeMilitarized Zone) using an additional DataHub as a proxy server for even greater security.

You've likely already heard about Cogent DataHub Version 9 and it's new MQTT integration capabilities.  The DataHub V9 MQTT Client goes beyond just generically connecting to MQTT Brokers by providing smart connectors for Azure IoT Hub, Google IoT and Amazon IoT Core MQTT Broker services.

The following short video blog demonstrates step-by-step how to easily configure the DataHub MQTT Client for publishing OPC UA and OPC DA data from DataHub to the Azure IoT Hub, as well as, pushing data from the many other data sources supported by Cogent DataHub (such as ODBC, DDE, Modbus and more).

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.
