CAN Error Frame Selectors

Valid for: CANoe DE • CANoe:lite DE • CANoe4SW DE • CANoe4SW:lite DE You can access information of the error frame object using the following selectors:

​
Identification

Note: The validity of ID and DLC depends on the error type and the error position!
  • CAN: Transmission channel or channel through which the frame error has been received.
    Value range: 1..32
    Type: word
  • MsgChannel: Transmission channel or channel through which the frame error has been received.
    Value range: 1..32
    Type: word
  • ID: Message Identifier
    This value is only available for some CAN hardware.
    Type: dword
  • DLC: Data Length Code
    This value is only available for some CAN hardware.
    Type: byte

​
Message Times and Lengths

  • Time_ns: Time stamp
    Unit: nanoseconds
    Type: Int64
  • Time: Time stamp
    Unit: 10µs
    Type: dword
  • SOF: Start-of-Frame time stamp in ns.
    This value is only available for some CAN hardware.
    Type: qword
  • ErrorPosition_Bit: Bit index where an error has been detected by the controller.
    This value is only available for some CAN hardware.
    Type: dword
  • ErrorPosition_Time: Difference between the time stamp of the error frame and the start of frame.
    Unit: nanoseconds
    This value is only available for some CAN hardware.
    Type: dword

​
Flags

  • FDF: FD Format Indicator
    This value is only available for some CAN hardware and a specific driver.
    Type: byte
  • BRS: CAN FD Bitrate Switch
    This value is only available for some CAN hardware and a specific driver.
    Type: byte
  • ESI: CAN FD Error State Indicator
    This value is only available for some CAN hardware and a specific driver.
    Type: byte
  • Phase: CAN FD phase.
    This value is only available for some CAN hardware and a specific driver.
    0: Error occurred in arbitration phase
    1: Error occurred in data phase
    Type: char

​
Error Code

  • ErrorCode: Error Code
    Type: word
  • CtrlType: CAN-controller type.
    The error code format depends on the type of CAN controller.
    0: unknown
    1: SJA1000
    2: CAN Core
    Type: byte

​
Data Access

  • Byte(x): Message data byte (unsigned 8 bit); possible values for x*: 0…63
    Type: byte
  • Word(x): Message data word (unsigned 16 bit); possible values for x*: 0…62
    The index is byte-oriented; for example, word(1) references to the data beginning at byte 1 and consists of byte 1…2 (16 bit).
    Type: word
  • DWord(x): Message data word (unsigned 32 bit); possible values for x*: 0…60
    The index is byte-oriented; for example, dword(1) references to the data beginning at byte 1 and consists of byte 1…4 (32 bit).
    Type: dword
  • QWord(x): Message data word (unsigned 64 bit); possible values for x*: 0…56
    Type: qword
  • char(x): Message data byte (signed 8 bit); possible values for x*: 0…63
    Type: char
  • int(x): Message data word (signed 16 bit); possible values for x*: 0…62
    The index is byte-oriented; for example, int(1) references to the data beginning at byte 1 and consists of byte 1…2 (16 bit).
    Type: int
  • long(x): Message data word (signed 32 bit); possible values for x*: 0…60
    The index is byte-oriented; for example, long(1) references to the data beginning at byte 1 and consists of byte 1…4 (32 bit).
    Type: long
  • int64(x): Message data word (signed 64 bit); possible values for x*: 0…56
    Type: int64
  • float(x): Message data interpreted as IEEE float (32 bit); possible values for x*: 0…60
    Type: float
  • double(x): Message data interpreted as IEEE double (64 bit); possible values for x*: 0…56
    Type: double
