According to the BACnet protocol documentation:

Defines a standardized object that provides a container to hold references to subordinate objects, which may include other Structured View objects, thereby allowing multilevel hierarchies to be created. The hierarchies are intended to convey a structure or organization such as a geographical distribution or application organization. Subordinate objects may reside in the same device as the Structured View object or in other devices on the network.

Objects of type structuredView have the following properties:

•defaultSubordinateRelationship

•description

•nodeSubtype

•nodeType

•objectIdentifier

•objectName

•objectType

•profileLocation

•profileName

•propertyList

•represents

•subordinateAnnotations

•subordinateList

•subordinateNodeTypes

•subordinateRelationships

•subordinateTags

•tags
