​
ARINC word selectors

  • Keyword: time
    • Description: When an event handler (on a429Word/on a429Worderror) is triggered, the time stamp of the event is stored in the selector. Unit: 10 µs
    • Type: dword
    • Access Limitation: read-only
  • Keyword: time_ns
    • Description: When an event handler (on a429Word/on a429Worderror) is triggered, the time stamp of the event is stored in the selector. Unit: nanoseconds
    • Type: int64
    • Access Limitation: read-only
  • Keyword: msgChannel
    • Description: Transmission channel (output) or the channel which triggered an event handler (on a429Word/on a429Worderror). Value range: 1..32
    • Type: word
    • Access Limitation: —
  • Keyword: ID
    • Description: Label value. Value range: 0..255
    • Type: dword
    • Access Limitation: —
  • Keyword: name
    • Description: Name of the ARINC word taken from the database (DBC)
    • Type: char[]
    • Access Limitation: read-only
  • Keyword: DIR
    • Description: This direction is related to the corresponding event. A dedicated ARINC-429 channel may be either an Rx or Tx channel, but not both. Value range: Rx (default), Tx
    • Type: byte
    • Access Limitation: read-only
  • Keyword: parity
    • Description: Overwrite the parity settings of a Tx channel for a specific ARINC word. The value may be changed with the function a429SetParity. Value range: 0: use channel configuration (default), 1: disable hardware parity support, 2: generate odd parity, 3: generate even parity
    • Type: word
    • Access Limitation: read-only
  • Keyword: TxCtrl
    • Description: Define the scheduling type for the ARINC word with a429SetScheduleTx and a429StopTx. Value range: 0: on request, 1: add to HW scheduler, 2: remove from HW scheduler
    • Type: byte
    • Access Limitation: read-only
  • Keyword: Error
  • Keyword: simulated
    • Description: If an ARINC event is detected this selector specifies whether the event was caused by CANoe DE product or not. Value range: 0: real event caused outside from the tool, 1: simulated event caused by the tool
    • Type: byte
    • Access Limitation: read-only
  • Keyword: TxCycle
    • Description: This is the cycle time (in microseconds) which is given to the HW scheduler with output. The cycle time is set with a429SetScheduleTx.
    • Type: dword
    • Access Limitation: read-only
  • Keyword: FrameLen
    • Description: Length of the detected ARINC word in nanoseconds.
    • Type: dword
    • Access Limitation: read-only
  • Keyword: BitRate
    • Description: Detected bitrate for the ARINC word.
    • Type: dword
    • Access Limitation: read-only
  • Keyword: Gap
    • Description: Specify the minimum distance to be kept for a scheduled ARINC word. This may be combined with the hardware scheduler. The gap may be set with a429SetGap in combination with a429CalcBitLength. The value is given in nanoseconds.
    • Type: dword
    • Access Limitation: read-only

    • Description: Access 8 bits in an ARINC word; x: 0..3
    • Type: —
    • Access Limitation: —
  • Keyword: word(x); int(x)
    • Description: Access 16 bits in an ARINC word; x: 0..2
    • Type: —
    • Access Limitation: —
  • Keyword: dword(x); long(x)
    • Description: Access 32 bits in an ARINC word; x: 0
    • Type: —
    • Access Limitation: —
The offsets used together with the selector address the following parts of the ARINC word.
  • Offset: 3, 2, 1, 0
  • Byte(0)/char(0): 0
  • Byte(1)/char(1):
  • Byte(2)/char(2):
  • Byte(3)/char(3):
  • Word(0)/int(0): 0
  • Word(1)/int(1):
  • Word(2)/int(2):
  • Dword(0)/long(0): 0
Meaning: Parity + SSM + Data, Data, Data + SDI, ARINC-Label Bit number: 32, 25, 24, 17, 16, 9, 8, 1
