Cogent DataHub enables a wide range of flexible connectivity options between interfaces for different data sources such as OPC UA, MQTT, OPC DA, ODBC, DDE and so much more.  This is why we commonly refer to DataHub as a "gateway", as it is frequently utilized for data integration by external software such as HMI, SCADA, MES, historians and other client applications, including for IIoT integration.

In Part 1 of our Cogent DataHub Virtual Training series, we will cover step-by-step how to easily connect OPC UA (Data Access Profile) client applications to your OPC DA Classic server data sources.

Watch this video to learn how to convert any OPC DA server to OPC UA (Data Access Profile) for connectivity from any OPC UA (Data Access Profile) client application using Cogent DataHub, including basic setup, for integrating a wide range of data sources.  Looking for other how-to videos for DataHub?  Click here!
