Mass¶

Overview¶

Data type

An actual value for a physical quantity of type NullableMass, i.e., a physical quantity that has a numerical value and a unit of measurement.

Supertypes

NullableMass

Attributes (data)

Name	Multiplicity	Type
Unit	1	MassUnit
Value	1	Double

Implementation in Proteus Schema

All data attributes with type NullableMass (the base type of Mass) are implemented as DEXPI generic attributes for physical quantities.

Example

The instance mass1 represents a Mass of 900.0 kg.

Implementation in Proteus Schema

<GenericAttribute
  Format="double"
  Value="900.0"
  Units="Kilogram"
  UnitsURI="http://data.posccaesar.org/rdl/RDS1328669" ...>

Note that the <GenericAttribute> element must have a Name and an AttributeURI attribute. They depend on the data type attribute of the DEXPI class that owns the instance mass1. For a complete example, see the attribute UpperLimitDesignLoad of the DEXPI class BatchWeigher.

Unit¶

Attribute (data)

The unit of measurement of the Mass.

Value¶

Attribute (data)

The numerical value of the Mass.
