Detailed Description

The QKnx2ByteUnsignedValue class is a datapoint type with a 2-byte unsigned value.

This is a fixed size datapoint type with the length of 2 bytes.

It is a base class for the following datapoint types:

  • QKnxBrightness - Brightness in LUX
  • QKnxLengthMilliMeter - Length in millimeters
  • QKnxPropDataType - Identifier Interface Object Property data type (no unit)
  • QKnxTimePeriod10Msec - Time in multiples of 10 milliseconds. Not allowed for runtime communication. This datapoint type shall only be used for parameters and diagnostic data or if specified as such in a functional block specification.
  • QKnxTimePeriod100Msec - Time in multiples of 100 milliseconds. Not allowed for runtime communication.
  • QKnxTimePeriodHrs - Time in hours
  • QKnxTimePeriodMin - Time in minutes. Not allowed for runtime communication.
  • QKnxTimePeriodMsec - Time in milliseconds
  • QKnxTimePeriodSec - Time in seconds
  • QKnxUEICurrentMilliA - Current in milliampere. The minimum value is 0, which means that no bus poser supply functionality is available.
  • QKnxValue2Ucount - Pulses

Integer values from 0 to 65 535 can be encoded in this datapoint type.

Member Function Documentation

QKnx2ByteUnsignedValue::QKnx2ByteUnsignedValue()

Creates a fixed size datapoint type with the value 0.

QKnx2ByteUnsignedValue::QKnx2ByteUnsignedValue(quint32 value)

Creates a fixed size datapoint type with the value value.

[protected] QKnx2ByteUnsignedValue::QKnx2ByteUnsignedValue(int subType, quint32 value)

Creates a fixed size datapoint type with the subtype subType and value value.

[override virtual] bool QKnx2ByteUnsignedValue::isValid() const

Reimplemented from QKnxDatapointType::isValid().

bool QKnx2ByteUnsignedValue::setValue(quint32 value)

Sets the value of the datapoint type to value.

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

See also value().

quint32 QKnx2ByteUnsignedValue::value() const

Returns the value stored in the datapoint type.

See also setValue().
