Detailed Description
A bus power supply unit is required for bus communications. It can be either a decentral (distributed) bus power supply unit, DPSU, or a central bus power supply unit, PSU.
The DPSU or PSU can be activated or deactivated also by mechanical means, such as using a jumper or a switch. The supported range is product specific. For example, disabled/enabled only or disabled/auto only.
The range for the Mode value is from Disabled, 0 to Automatic, 2.
This is a fixed size datapoint type with the length of 1 byte.
See also QKnxDatapointType, QKnx1Byte, and Qt KNX Datapoint Type Classes.
Member Type Documentation
enum class QKnxPsuMode::Mode
This enum holds the bus power supply unit mode stored in the datapoint type.
| Constant | Value | Description |
|---|---|---|
QKnxPsuMode::Mode::Disabled | 0x00 | The PSU or DPSU in the device is switched off. |
QKnxPsuMode::Mode::Enabled | 0x01 | The PSU or DPSU in the device is switched on. |
QKnxPsuMode::Mode::Automatic | 0x02 | The PSU or DPSU in the device was turned on or off automatically. For example, by sending a message on the bus. |
QKnxPsuMode::Mode::Invalid | 0xff | The mode is invalid. |
