5.2 HistoricalDataNodes

5.2.3 HasHistoricalConfiguration ReferenceType

This ReferenceType is a concrete ReferenceType that can be used directly. It is a subtype of the Aggregates ReferenceType and will be used to refer from a Historical Node to one or more HistoricalDataConfigurationType Objects.

The semantic indicates that the target Node is “used” by the source Node of the Reference. Figure 2 informally describes the location of this ReferenceType in the OPC UA hierarchy. Its representation in the AddressSpace is specified in Table 5.
