OPC UA Server

The OPC Router’s OPC UA Server plug-in allows you to expose data, processes, and functions as a standards-compliant OPC UA interface. This enables OPC UA clients to access information that is collected, processed, and made available by the OPC Router from various data sources.

The plug-in supports reading and writing data, executing methods, and providing metrics for diagnostic and monitoring purposes. In addition, existing OPC UA information models can be integrated via NodeSets. NodeSets can be imported, for example, from CloudLib or other sources and made available in the OPC UA server.

For details on importing and using NodeSets, see the NodeSets chapter.
