Restrictions

Please note the following restrictions when using this plugin.

  • FV, MAC, and payload bit positions must be configured consecutively. Position in Truncated FV Position, Truncated MAC Position, and CAN/CAN-FD Payload [Truncated] on the Ch Setting tab of Security Setting must not overlap and must be contiguous. Example: MAC = bits 32 to 63, FV = bits 24 to 31, Payload = bits 0 to 23.

  • Payload values support only static configuration. You cannot choose a generation method like FV or MAC. Set values directly in the Data Setting dialog. Dynamic runtime changes are not supported.

  • Bit alignment and byte endian are fixed. In the Element Setting dialog, Bit Alignment is fixed to Right, and Byte Endian is fixed to Big.

  • There is an upper limit for cyclic transmit messages with CAN ID message authentication. Up to 10 entries per channel and up to 64 entries total across all channels.

  • There is a lower limit for cyclic transmission period. The minimum cycle of cyclic transmit messages is n x 1 ms, where n is the total number of authenticated CAN IDs configured across the two channels in the same MicroPeckerX. Example: if Ch1 has 2 entries and Ch2 has 3 entries, the minimum cycle is 5 ms. Even if Cycle on the ID Setting tab of Security Setting is set below this minimum, the actual cycle is automatically adjusted to at least n x 1 ms.

  • Unsupported features

    • Retry transmission on send failure
    • Spoofed transmission using another node ID
    • Log replay
