constraints

Lexicon: eco.wonderland.workcell.device.data.property.defs
Type: object

Organize a set of expected values that can be reported for a dataItem.

Properties

maximum

Type: binary32

Numeric upper constraint. If the data reported for a data item is a range of numeric values, the expected value reported MAY be described with an upper limit defined by this constraint.

minimum

Type: binary32

Numeric lower constraint. If the data reported for a data item is a range of numeric values, the expected value reported MAY be described with a lower limit defined by this constraint.

nominal

Type: binary32

Numeric target or expected value.

value

Type: [ string ]

Single data value that is expected to be reported for a dataItem. value MUST NOT be used in conjunction with any other constraint elements.

filter
