6.6 RtlsDeviceType

6.6.1 General

This OPC UA ObjectType represents an RTLS device. It defines additional methods and properties required for managing RTLS sensors or systems, and to retrieve information on located objects, either via a direct method call or returned by location events.

Figure 11 shows an overview for the RtlsDeviceType with its Methods, Property and related ObjectType. It is formally defined in Table 16.

6.6.2 ObjectType definition

The RtlsDeviceType is formally defined in Table 16.

The RtlsDeviceType ObjectType is a concrete type and can be used directly.

6.6.3 ObjectType Description

6.6.3.1 Method Scan

This method executes the location acquisition process of the RTLS device or system. It overwrites the Scan method of the AutoIdDeviceType defined in 6.1.3.4.

Signature

	Scan (
		[in]	ScanSettings				Settings
		[out]	RtlsLocationResult []			Results
		[out]	AutoIdOperationStatusEnumeration	Status
		);
	

Method Result Codes

6.6.3.2 Method GetLocation

This method queries the RTLS device or system synchronous and returns the location of an object. Depending on vendor-specific implementation, it may initiate a location or range acquisition and synchronously return a result, or the RTLS device may return the last known location of the object (the age of the last location acquisition will be apparent from the timestamp returned in the result).

Signature

	GetLocation (
		[in]	ScanData			Identifier
		[in]	CodeTypeDataType		CodeType
		[in]	LocationTypeEnum		LocationType
		[out]	RtlsLocationResult	Result
		);
	

Method Result Codes

6.6.3.3 Method GetSupportedLocationTypes

This method returns the RTLSLocationTypes (as defined in RTLSLocationTypeEnum and in section 8.3) the RTLS device or system supports. At least one Type must be returned. The first type that is returned (first position in the resulting array) is the default type that the RTLS device or system will use.

Signature

	GetSupportedLocationTypes (
		[out]	LocationTypeEnumeration[]	SupportedLocationTypes
		);
