7.2.3.5 IfcController

7.2.3.5.1 Semantic definition

A controller is a device that monitors inputs and controls outputs within a building automation system.

A controller may be physical (having placement within a spatial structure) or logical (a software interface or aggregated within a programmable physical controller).

7.2.3.5.4 Formal propositions

Name Description
CorrectPredefinedType

Either the PredefinedType attribute is unset (e.g. because an IfcControllerType is associated), or the inherited attribute ObjectType shall be provided, if the PredefinedType is set to USERDEFINED.

NOT(EXISTS(PredefinedType)) OR
(PredefinedType <> IfcControllerTypeEnum.USERDEFINED) OR
((PredefinedType = IfcControllerTypeEnum.USERDEFINED) AND EXISTS (SELF\IfcObject.ObjectType))
CorrectTypeAssigned

Either there is no controller type object associated, i.e. the IsTypedBy inverse relationship is not provided, or the associated type object has to be of type IfcControllerType.

(SIZEOF(IsTypedBy) = 0) OR
('IFC4X3_DEV_738df036.IFCCONTROLLERTYPE' IN TYPEOF(SELF\IfcObject.IsTypedBy[1].RelatingType))
