Connect OPC UA servers and clients
OPC Unified Architecture, or OPC UA, is the latest standard from the OPC Foundation, with improvements over OPC Classic in the areas of data security, networking, and platform independence.
Starting with version 8, the Cogent DataHub can now act as both an OPC UA Server and as an OPC UA Client. This means the DataHub can collect, aggregate and distribute data from OPC UA servers and make this data available to any OPC UA client application, either on the same computer, or over the network using UA tunneling.
When designing the UA interfaces in the DataHub, a primary goal has been to make UA connectivity as easy as possible for the end user. With the DataHub, you do not need to be a UA expert to use UA effectively in your operations. In order for an OPC UA client and server to connect they must share their certificates. The DataHub makes trusting incoming certificates easy to manage with only a few clicks.
Our OPC UA feature, like the other collection methods of the DataHub, is integrated with all the other DataHub features. This allows you to do things like write UA data to a database, analyze it in Excel or visualize it using WebView. The feature I see being used the most is the ability for OPC UA systems to seamlessly connect to OPC DA systems through bridging and tunneling. This will be especially important over the next few years as we watch the transition from OPC DA to OPC UA.
