Examples for the module no. and the CAN identifier
6 bytes are necessary for the initialisation of a module. The transmitted structure has to have the correct
length and the functions corresponding to the module type of board. If this is not the case, the module
would not react to the initialisation.
The table below shows the construction of the INIT Id. In the command byte and the sub command
bytes the function of the respective initialisation level is determined. The module no. selects the wanted
module. In the cells parameter 1 and 2 the wanted parameters are transmitted.
Byte no. Function Value range
1 Command $00...$FF
2 Sub command 1 $00...$FF
3 Sub command 2 1*) $00...$FF 1*)
4 Module no. $00, $01...$FF
5 Parameter 1 $00...$FF
6 Parameter 2 $00...$FF

(*) Byte 3 (sub command 2) is not needed for the majority of commands and parameters. In this case it should always be
allocated with $00.
