Hello @piaochunri ,
I’m assuming you are using the RDB3 board. Then the 32 bits (0 – 31) you see in the excel file represent the 4 dip switches present in your board:

You can check the schematic to see the order of the bytes [page 32, S32G-VNP-RDB3, SPF-53060.pdf] available in deseing files section of the S32G-VNP-RDB3 product page:

You can check the User Guide to learn more about the different switch configurations [Starting in page 3, Chapter 3, S32G-VNP-RDB3 Switch Setting, S32G-VNP-RDB3 User Guide, Rev. 1.0, 03/2023] available in de documentation section of the S32G-VNP-RDB3 product page:






Let me know if this information solved your question.
