Detailed Description

This datapoint type stores fault signals transmitted in the application area QKnxApplicationArea::SystemFunctionCommonInterest.

The range for the Error value is from No fault, 0 to Group object type exceeds, 18.

This is a fixed size datapoint type with the length of 1 byte.

Member Type Documentation

enum class QKnxErrorClassSystem::Error

This enum holds the system error stored in the datapoint type.

Constant	Value	Description
`QKnxErrorClassSystem::Error::NoFault`	`0x00`	No fault signals were transmitted.
`QKnxErrorClassSystem::Error::GeneralDeviceFault`	`0x01`	An error occurred in the RAM, EEPROM, UI, watchdog, and so on.
`QKnxErrorClassSystem::Error::CommunicationFault`	`0x02`	A communication error occurred. For example, a failure in a formerly present communication partner or a timeout in the system clock signal (heartbeat).
`QKnxErrorClassSystem::Error::ConfigurationFault`	`0x03`	A configuration error was detected. For example, two devices with the same individual address were detected or multiple system clocks were set as the master clock.
`QKnxErrorClassSystem::Error::HardwareFault`	`0x04`	A hardware error occurred.
`QKnxErrorClassSystem::Error::SoftwareFault`	`0x05`	A software error occurred.
`QKnxErrorClassSystem::Error::InsufficientNonVolatileMemory`	`0x06`	Not enough non-volatile memory
`QKnxErrorClassSystem::Error::InsufficientVolatileMemory`	`0x07`	Not enough volatile memory
`QKnxErrorClassSystem::Error::MemoryAllocationCommandWithSize0Received`	`0x08`	A memory allocation command with the size 0 was received.
`QKnxErrorClassSystem::Error::CrcError`	`0x09`	A CRC error occurred.
`QKnxErrorClassSystem::Error::WatchdogResetDetected`	`0x0a`	A watchdog reset was detected.
`QKnxErrorClassSystem::Error::InvalidOpCodeDetected`	`0x0b`	An invalid OP code was detected.
`QKnxErrorClassSystem::Error::GeneralProtectionFault`	`0x0c`	A general protection error was detected.
`QKnxErrorClassSystem::Error::MaximalTableLengthExceeded`	`0x0d`	The maximum table length was exceeded.
`QKnxErrorClassSystem::Error::UndefinedLoadCommandReceived`	`0x0e`	An undefined load command was received.
`QKnxErrorClassSystem::Error::GroupAddressTableIsNotSorted`	`0x0f`	The group address table is not sorted.
`QKnxErrorClassSystem::Error::InvalidConnectionNumberTsap`	`0x10`	The connection number TSAP is invalid.
`QKnxErrorClassSystem::Error::InvalidGroupObjectNumberAsap`	`0x11`	The connection number ASAP is invalid.
`QKnxErrorClassSystem::Error::GroupObjectTypeExceeds`	`0x12`	The group object type exceeds `PID_MAX_APDU_LENGTH H - 2`.
`QKnxErrorClassSystem::Error::Invalid`	`0xff`	The value is invalid.
