IfcElectricTimeControl: public Ifc4::IfcFlowController¶
An electric time control is a device that applies control to the provision or flow of electrical energy over time.
HISTORY New entity in IFC2x4
Type Use Definition IfcElectricTimeControl defines the occurrence of any electric time control; common information about electric time control types is handled by IfcElectricTimeControlType. The IfcElectricTimeControlType (if present) may establish the common type name, usage (predefined type), properties, materials, ports, composition, assignments, and representations. The IfcElectricTimeControlType is attached using the IfcRelDefinesByType objectified relationship and is accessible by the IsTypedBy inverse attribute. If the IfcElectricTimeControlType has ports or aggregated elements, such objects are reflected at the IfcElectricTimeControl occurrence using the IfcRelDefinesByObject relationship.
Property Use Definition The property sets relating to this entity are defined by IfcPropertySet and attached by the IfcRelDefinesByProperties relationship. They are accessible by the IsDefinedBy inverse attribute. Property sets may also be specified at the IfcElectricTimeControlType, defining the common property data for all occurrences of the same type. They are then accessible by the IsTypedBy inverse attribute pointing to IfcElectricTimeControlType.HasPropertySets. If both are given, then the properties directly defined at IfcElectricTimeControl override the properties defined at IfcElectricTimeControlType. Refer to the documentation at the supertype IfcFlowController and ancestors for inherited property set definitions. The following property set definitions are applicable to this entity: Pset_ElectricTimeControlTypeCommon (PSET_TYPEDRIVENOVERRIDE)
Quantity Use Definition The quantities relating to this entity are defined by IfcElementQuantity and attached by the IfcRelDefinesByProperties relationship. They are accessible by the IsDefinedBy inverse attribute. The following base quantities are defined and shall be exchanged with the IfcElementQuantity.Name = ‘BaseQuantities’. Other quantities, being subjected to local standard of measurement, may be defined with another string value assigned to Name. In this case a valid value for MethodOfMeasurement shall be provided.
Material Use Definition The material of the IfcElectricTimeControl is defined by IfcMaterialConstituentSet or as a fallback by IfcMaterial, and attached by the RelatingMaterial attribute on the IfcRelAssociatesMaterial relationship. It is accessible by the HasAssociations inverse attribute. Material information can also be given at the IfcElectricTimeControlType, defining the common attribute data for all occurrences of the same type. The following keywords for IfcMaterialConstituentSet.MaterialConstituents[n].Name shall be used:
Casing: Material from which the casing is constructed.
Port Use Definition The distribution ports relating to the IfcElectricTimeControl are defined by IfcDistributionPort and attached by the IfcRelConnectsPortToElement relationship. If the electric time control occurrence is defined by IfcElectricTimeControlType, then the port occurrences must reflect those defined at the IfcElectricTimeControlType using the IfcRelDefinesByObject relationship. Ports are specific to the IfcElectricTimeControl PredefinedType as follows indicated by the IfcDistributionPort Name, PredefinedType, and FlowDirection:
Line (ELECTRICAL, SINK): Receives electrical power. Load (ELECTRICAL, SOURCE): Transmits electrical power according to time.
Whether the optional attribute PredefinedType is defined for this IfcElectricTimeControl.
