  • rx_functional (InputAIParamsAlias) – Addressing Information parameters used for incoming functionally addressed communication.

  • tx_functional (InputAIParamsAlias) – Addressing Information parameters used for outgoing functionally addressed communication.

property addressing_format: uds.can.addressing_format.CanAddressingFormat

CAN Addressing format used.

Return type:

uds.can.addressing_format.CanAddressingFormat

AI_DATA_BYTES_NUMBER: int = 1

Number of CAN Frame data bytes that are used to carry Addressing Information.
