Description

A Device organizesact of containing and owning one or more elements. its parts as «abstract» Component entities.

A Device MUST have a Device::name and Device::uuid to identify itself.

A Device MUST have the following DataItems: Availability, AssetChanged, and AssetRemoved.

See Components for more details on the properties of Device.

See Section Part Properties of Device for a list of top levelelement that represents the most significant physical or logical functions of a piece of equipment. «abstract» Component types for a Device.

Properties

Name	Type	Int	Dep	Multiplicity	Description
id	ID	1.0		1	unique identifier for the «abstract» Component.
name	string	1.0		0..1	name of the «abstract» Component. When provided, «abstract» Component::name MUST be unique for all child «abstract» Component entities of a parent «abstract» Component.
nativeName	string	1.1		0..1	common name associated with «abstract» Component.
sampleInterval	float	1.2		0..1	interval in milliseconds between the completion of the reading of the data associated with the «abstract» Component until the beginning of the next sampling of that data. This information may be used by client software applications to understand how often information from a «abstract» Component is expected to be refreshed. The refresh rate for data from all child «abstract» Component entities will be the same as for the parent «abstract» Component element unless specifically overridden by another «abstract» Component::sampleInterval provided for the child «abstract» Component.
sampleRate	float	1.0	1.2	0..1	DEPRECATED in MTConnect Version 1.2. Replaced by «abstract» Component::sampleInterval.
uuid	UUID	1.0		0..1	universally unique identifier for the «abstract» Component.
coordinateSystemIdRef	ID	1.8		0..1	specifies the CoordinateSystem for this «abstract» Component and its children.
