    Information about a signal decoder.

    • fullyQualifiedName (string) – [REQUIRED]

      The fully qualified name of a signal decoder as defined in a vehicle model.

    • type (string) – [REQUIRED]

      The network protocol for the vehicle. For example, CAN_SIGNAL specifies a protocol that defines how data is communicated between electronic control units (ECUs). OBD_SIGNAL specifies a protocol that defines how self-diagnostic data is communicated between ECUs.

    • interfaceId (string) – [REQUIRED]

      The ID of a network interface that specifies what network protocol a vehicle follows.

    • canSignal (dict) –

      Information about signal decoder using the Controller Area Network (CAN) protocol.

        This value might be different from the value in a DBC file. For little endian signals, startBit is the same value as in the DBC file.

      • byteLength (integer) – [REQUIRED]

        The length of a message.

        The number of bits to mask in a message.

    • messageSignal (dict) –

      The decoding information for a specific message which supports higher order data types.
