Hi,

I'm trying to decipher this document I found online, can someone please help me, I can only see two CAN IDs...

CAN ID 0x35C a table with just one byte
CAN ID 0x359 a table with four bytes

Then there are seven tables with no CAN ID:

6 bytes
4 bytes
6 bytes
8 bytes
8 bytes
8 bytes
8 bytes

Or are the above seven tables all 0x359 also, if so, how does the CANbus system know which table is which, the data is sent in order:

0x35C - 1 byte
0x359 - 4 bytes, 6 bytes, 4 bytes, 6 bytes, 8 bytes, 8 bytes, 8 bytes & 8 bytes

So 0x359 is like 52 bytes in total?

CAN ID 0x359 is sent in eight separate frames after each other all with CAN ID 0x359?

Also it doesn't mention any reply/confirmations?

Thanks.
Richard
