7 OPC UA ObjectTypes

7.2 WSBaseObjectType Definition

The WSBaseObjectType is formally defined in Table 16. This data type is required for compatibility with WS Protocol, where the WS TagNumber is usually used to identify a WS DataPoint. In OPC UA the WS BrowseName shall be used as BrowseName for identification. Thus the WSTagNumber property is optional.
