Include CAN identifier for CRC parameter

hongxiang yu 2 years ago in IQANdesign • updated by Gustav Widén (System support) 2 years ago • 1

Hello 

    About Include CAN identifier in CRC parameter is that include PGN + priority + J1939 source address+data ?

As i made test seems they are concerned. My supplier obviously told me that the CRC calculate only related to PGN+data but it is strange that i need select Yes for include CAN identifier then i can get correct CRC results which supplier provide example for me. So that i hope to confirm CAN identifier elements.

Yes, all bytes of the identifier are included when you select the option Include CAN identifier on the frame.


You can easily observe this if you change the SA or priority, then your CRC will be different.
