How to Configure OPC UA

How to Configure OPC UA

Instructor: Scott Sommer, PE, CAP

OPC UA makes it possible to exchange process data, alarms and events, and historical data all from one client and server application. The original OPC UA specification was released in 2006.

OPC UA is not based upon DCOM, but rather on a protocol stack built on top of the well-known TCP/IP protocol, the backbone of Ethernet and the internet.
This structure opens up a lot of possibilities for grouping and managing data in “blocks” rather than just pieces of data based upon an individual tag item.

As with OPC Classic, OPC UA is a client-server based application.

  • 3. How is OPC UA Configured?

    In this video, you will learn how a common OPC UA Client can be configured to subscribe to, or in other words, collect data from an OPC UA Server.

    You will also learn how to use the Server’s URL address to establish a connection and how to configure a subscription.

  • 4. An Example of Using OPC UA

    In this video, I will demonstrate the configuration of an OPC UA Client to collect data at defined intervals through subscriptions, configuration of an OPC UA Server from a second manufacturer, and establishment of multiple OPC UA Server connections from a single OPC UA Client.
