类型文档编制

enum class QKnx:: EmiType
flags QKnx:: EmiTypes

This enum describes the various external message interface (EMI) types supported by KNX bus.

常量	值	描述
QKnx::EmiType::Unknown	0x00	The supported EMI type is unknown.
QKnx::EmiType::EMI1	0x01	The supported EMI is type 1 used by bus coupler units (BCU) model type 1.
QKnx::EmiType::EMI2	0x02	The supported EMI is type 2 used by bus coupler units (BCU) model type 2.
QKnx::EmiType::cEMI	0x04	The supported EMI type is known as common EMI and a generic structure for medium independent KNX messages.

该枚举在 Qt 5.12 引入或被修改。

The EmiTypes type is a typedef for QFlags <EmiType>. It stores an OR combination of EmiType values.

enum class QKnx:: InterfaceFeature

This enumeration contains the values to identify an interface feature service (also known as device feature).

常量	值	描述
QKnx::InterfaceFeature::Unknown	0x00	The used feature service is unknown.
QKnx::InterfaceFeature::SupportedEmiType	0x01	Getting the supported EMI type(s).
QKnx::InterfaceFeature::HostDeviceDescriptorType0	0x02	Getting the local device descriptor type 0 for possible local device management.
QKnx::InterfaceFeature::BusConnectionStatus	0x03	Getting and informing on the bus connection status.
QKnx::InterfaceFeature::KnxManufacturerCode	0x04	Getting the manufacturer code of the bus access server.
QKnx::InterfaceFeature::ActiveEmiType	0x05	Getting and setting the EMI type to use.
QKnx::InterfaceFeature::IndividualAddress	0x06	Getting the individual address used by the bus interface.
QKnx::InterfaceFeature::MaximumApduLength	0x07	Getting the maximal APDU-length that can be transported over a KNXnet/IP tunneling connection.
QKnx::InterfaceFeature::InterfaceFeatureInfoServiceEnable	0x08	Controlling the use of the info feature service by the interface.

该枚举在 Qt 5.12 引入或被修改。

enum class QKnx:: MediumStatus

This enum type holds the medium status if the KNXnet/IP router or server supports extended device information.

常量	值	描述
QKnx::MediumStatus::Unknown	0xff	The medium status is unknown. Most likely the discovered KNXnet/IP router or server does not support extended device information.
QKnx::MediumStatus::CommunicationPossible	0x00	Communication to a KNX twisted pair 1 (TP1) network via the discovered KNXnet/IP router or server is possible.
QKnx::MediumStatus::CommunicationImpossible	0x01	Communication to a KNX TP1 network via the discovered KNXnet/IP router or server is not possible.

该枚举在 Qt 5.12 引入或被修改。

enum class QKnx:: MediumType

This enum describes the various medium types supported by KNX bus.

常量	值	描述
QKnx::MediumType::Unknown	0x00	The supported medium type is unknown.
QKnx::MediumType::TP	0x01	The supported medium type is twisted pair 1.
QKnx::MediumType::PL	0x04	The supported medium type is power-line 110.
QKnx::MediumType::RF	0x10	The supported medium type is radio frequency.
QKnx::MediumType::NetIP	0x20	The supported medium type is KNXnet/IP.

enum class QKnx:: ReturnCode

This enumeration contains the generic return codes used in the KNX specification.

常量	值	描述
QKnx::ReturnCode::Success	0x00	The service, function, or command was executed successfully, without additional information.
QKnx::ReturnCode::SuccessWithCrc	0x01	Positive confirmation of a message with CRC16-CCITT (beginning after the APCI octet, over received data including address and number of data octets).
QKnx::ReturnCode::MemoryError	0xf1	Memory cannot be accessed at all or only with faults.
QKnx::ReturnCode::CommandInvalid	0xf2	The command is not supported by this server.
QKnx::ReturnCode::CommandImpossible	0xf3	The command is supported and well formatted, but it cannot be executed, because a dependency is not fulfilled.
QKnx::ReturnCode::LengthExceedsMaxApduLength	0xf4	The requested data will not fit into a frame supported by this server. This return code indicates device limitations of the maximum supported frame length while accessing the resources of the device, such as properties, function properties, and memory.
QKnx::ReturnCode::DataOverflow	0xf5	An attempt was made to write data beyond what is reserved for the addressed resource.
QKnx::ReturnCode::DataMin	0xf6	The write value was too low. If the value is lower than the lowest supported value, then preferably this value shall be given instead of Value not supported .
QKnx::ReturnCode::DataMax	0xf7	The write value was too high. If the value is higher than the highest supported value, then preferably this value shall be given instead of Value not supported .
QKnx::ReturnCode::DataVoid	0xf8	The service or the function (property) is supported, but the requested data is not valid for this receiver. This value shall also be given if the requested data contains an enumeration value that is not supported, within the supported ranges.
QKnx::ReturnCode::TemporarilyNotAvailable	0xf9	The data could be written, but it is not possible at the time, because another management client (MaC) is accessing the data or the data is currently processed by a management server (MaS) (for example, being flashed or being renewed).
QKnx::ReturnCode::AccessWriteOnly	0xfa	Read access was attempted to a write only service or resource. This means resources such as properties, function properties, or memory that can be written, but that cannot be read.
QKnx::ReturnCode::AccessReadOnly	0xfb	Write access was attempted to a read only service or resource. This means resources such as properties, function properties, or memory that can be read, but that cannot be written.
QKnx::ReturnCode::AccessDenied	0xfc	The access to the data or function was denied because of authorization reasons, authorize request, or KNX security.
QKnx::ReturnCode::AddressVoid	0xfd	The interface object or the property is not present, or the index is out of range.
QKnx::ReturnCode::DataTypeConflict	0xfe	Write access with a wrong data type (datapoint length).
QKnx::ReturnCode::Error	0xff	The service, function, or command has failed without additional information about the problem.
