7.2.4.16 Pset_ControllerTypeTwoPosition

PSET_TYPEDRIVENOVERRIDE / IfcController / TWOPOSITION

Controller Type Two Position: Properties for signal handling for an analog controller taking disparate valued multiple inputs and creating a single valued binary output. HISTORY: In IFC4, extended properties to replace Pset_BinaryInput and Pset_BinaryOutput.

NameTypeDescription
ControlType P_ENUMERATEDVALUE / IfcLabel / PEnum_ControllerTwoPositionType
Control TypeThe type of signal modification effected and applicable ports: LOWERLIMITSWITCH: Single analog input is read and if less than Value.LowerBound then True is written to the output value. UPPERLIMITSWITCH: Single analog input is read and if more than Value.UpperBound then True is written to the output value. LOWERBANDSWITCH: Single analog input is read and if less than Value.LowerBound+BandWidth then True is written to the output value. UPPERBANDSWITCH: Single analog input is read and if more than Value.UpperBound-BandWidth then True is written to the output value. NOT: Single binary input is read and the opposite value is written to the output value. AND: Two binary inputs are read and if both are True then True is written to the output value. OR: Two binary inputs are read and if either is True then True is written to the output value. XOR: Two binary inputs are read and if one is true then True is written to the output value. CALENDAR: No inputs; the current time is compared with an IfcWorkCalendar to which the IfcController is assigned and True is written if active. INPUT: Controller element is a dedicated input. OUTPUT: Controller element is a dedicated output. VARIABLE: Controller element is an in-memory variable.

Labels P_TABLEVALUE / IfcBoolean / IfcLabel
LabelsTable mapping values to labels, where such labels indicate the meanings of True and False, such as 'Open' and 'Closed'
Polarity P_SINGLEVALUE / IfcBoolean
PolarityTrue indicates normal polarity; False indicates reverse polarity.
Value P_SINGLEVALUE / IfcBoolean
ValueThe default value such as normally-closed or normally-open.
