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 - Property data type
  • QKnxTimePeriod10Msec - Time in 10 milliseconds
  • QKnxTimePeriod100Msec - Time in 100 milliseconds
  • QKnxTimePeriodHrs - Time in hours
  • QKnxTimePeriodMin - Time in minutes
  • QKnxTimePeriodMsec - Time in milliseconds
  • QKnxTimePeriodSec - Time in seconds
  • QKnxUEICurrentMilliA - Current in milliampers (no bus poser supply functionality available)
  • QKnxValue2Ucount - Pulses

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

See also QKnxDatapointType.
