Connect to an OPC UA data source

The OPC UA data source is a top-level node that can be added to the Gateway Communication Driver configuration. When the Gateway Communication Driver connects to the OPC UA server:

• One connection is created per OPC UA hierarchy.

• One subscription is created for each OPC UA group.

To connect to an OPC UA data source, create and configure its hierarchy (data source and groups), and use the proper item naming conventions in its client(s).

Refer to Configure the Gateway Communication Driver for a general overview about configuring data sources in the Gateway Communication Driver.
