IFC (IFC4X3_ADD2) under development Pset_SensorPHistory Semantic definition

Properties for history of controller values. HISTORY: Added in IFC4. Applicable entities Properties

Name Property Type Data Type Description
Value IfcPropertyReferenceValue IfcTimeSeries

The expected range and default value.

Indicates sensed values over time which may be recorded continuously or only when changed beyond a particular deadband. The range of possible values is defined by the SetPoint property of the corresponding sensor type property set.

Direction IfcPropertyReferenceValue IfcTimeSeries

Indicates sensed direction for sensors capturing magnitude and direction measured from True North (0 degrees) in a clockwise direction.

Quality IfcPropertyReferenceValue IfcTimeSeries

Indicates the quality of measurement or failure condition, which may be further qualified by the Status. True: measured values are considered reliable; False: measured values are considered not reliable (i.e. a fault has been detected); Unknown: reliability of values is uncertain.

Status IfcPropertyReferenceValue IfcTimeSeries

Status of the element, predominately used in renovation or retrofitting projects. The status can be assigned to as "New" - element designed as new addition, "Existing" - element exists and remains, "Demolish" - element existed but is to be demolished, "Temporary" - element will exists only temporary (like a temporary support structure).
