Header: #include <QKnxApplicationArea>
qmake: QT += knx
Inherits: QKnx1Byte

Public Types

enum Area { NoFault, SystemFunctionCommonInterest, HvacGeneralFBs, HvacHotWaterHeating, ..., Invalid }

Public Functions

QKnxApplicationArea(QKnxApplicationArea::Area area)
QKnxApplicationArea::Area area() const
bool setArea(QKnxApplicationArea::Area area)

Reimplemented Public Functions

virtual bool isValid() const override

Detailed Description

The range for the Area value is from No fault, 0 to Shutters and blinds, 50.

Faults in functions of common interest are mapped to the application area SystemFunctionCommonInterest. For example, a multiple system clock master conflict is a QKnxErrorClassSystem::ConfigurationFault within the SystemFunctionCommonInterest application area.

Faults in heating, ventilation, and air conditioning (HVAC) are mapped to the application areas HvacGeneralFBs, HvacHotWaterHeating, HvacDirectElectricalHeating, HvacTerminalUnits, and HvacVac.

This is a fixed size datapoint type with the length of 1 byte.

Member Function Documentation

QKnxApplicationArea::QKnxApplicationArea(QKnxApplicationArea::Area area)

Creates a fixed size datapoint type with the the application area set to area.


Creates a fixed size datapoint type with the application area set to NoFault.

QKnxApplicationArea::Area QKnxApplicationArea::area() const

Returns the application area stored in the datapoint type.

See also setArea().

[override virtual] bool QKnxApplicationArea::isValid() const

Reimplements: QKnx1Byte::isValid() const.

bool QKnxApplicationArea::setArea(QKnxApplicationArea::Area area)

Sets the application area stored in the datapoint type to area.

Returns true if the byte was set; otherwise returns false.
