Description

Component is an abstract entity and will be realized by specific Component types for an MTConnectDevices entity. See Component Types for more details on the Component types.

Component also provides structure for describing the lower levelnested element that is below a higher level element. entities associated with it.

At least one of Component, DataItem, or Reference entities MUST be provided for a Component.

Component Example

Properties

Name	Type	Int	Dep	Multiplicity	Description
`id`	`ID`	1.0		1	unique identifier for the `Component`.
`name`	`string`	1.0		0..1	name of the `Component`. When provided, `name` MUST be unique for all child `Component` entities of a parent `Component`.
`nativeName`	`string`	1.1		0..1	common name associated with `Component`.
`sampleInterval`	`float`	1.2		0..1	interval in milliseconds between the completion of the reading of the data associated with the `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 `Component` is expected to be refreshed. The refresh rate for data from all child `Component` entities will be the same as for the parent `Component` element unless specifically overridden by another `sampleInterval` provided for the child `Component`.
~~`sampleRate`~~	`float`	1.0	1.2	0..1	DEPRECATED in MTConnect Version 1.2. Replaced by `sampleInterval,Component`.
`uuid`	`ID`	1.0		0..1	universally unique identifier for the `Component`.
`coordinateSystemIdRef`	`ID`	1.8		0..1	specifies the `CoordinateSystem` for this `Component` and its children.
