OPC UA ObjectTypes – OPC Unified Architecture

7 OPC UA ObjectTypes

7.1 ZoneType definition

7.1.1 Overview

The ZoneType defines an area, in which a local location is computed, e.g. via a RTLS or a proximity based system like RFID. For that reason, it might either have a set of GroundControlPoints defining the extent for RTLS or just a point and a radius for proximity based systems. It is formally defined in Table 15.

The child Nodes of the ZoneType have additional Attribute values defined in Table 16.

Table 16 – ZoneType Attribute values for child Nodes

BrowsePath	Description Attribute
ZoneId	A unique identifier of the zone (e.g. a GUID).
Building	Name of the building
Floor	Name of the floor
Site	Name of the site
GroundControlPoints	Points defining the extent of the zone
Position	Describes a point (i.e. a position) in 2 or 3 dimensions.
Radius	For proximity-based systems. Describes the zone as a circular region with a given radius in meters around the position.
IncompleteConfiguration	Indicates if the configuration is complete. FALSE if configuration is complete.
