OPC Unified Architecture (OPC UA) is an interoperability standard for exchanging real-time data between clients and servers. This software includes an OPC UA Server module that you can use to make your project tags available to OPC UA clients on the network.

The OPC UA Server module is turned off by default. In order to use the server, you need to configure its communication settings, select the project tags that you want to make available to clients, and then start the OPC UA Server Runtime task. You might also need to manage program certificates so that the server and its clients can communicate securely with each other. This section describes how to do all of these things.
