Browse or discover the OPC UA address space

PI Data Collection Manager provides the user with an option to initiate discovery by browsing the OPC UA address space. This discovery procedure must be performed at least once.

Users have the option to specify a set of "Root NodeIDs".

Explicitly naming those hierarchy sub-sections (Root NodeIDs) allows for an initial constraining of the number of objects the discovery calls bring back. The OPC UA objects that are discovered are displayed in a hierarchical fashion for further selection.

To initiate the discovery in PI Data Collection Manager, navigate to the Data tab on the right side pane of the Connectors page and click Discover Data Source Contents. To select from the discovered objects, navigate to the data selection page through the Select Data button.
