7.2.3.5 IfcController

Organe de contrôle
Regler

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).

Formal Propositions:

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.
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.
