QKnx2ByteUnsignedValue (int subType , quint32 value )

详细描述

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.
