data : 00

    22

    23

 1 - Wants to generate SYNC every 10 milliseconds

    24

    25

1a - put the value (4 bytes) : 0x00002710 in its dictionary 

    26

index 0x1006, subindex 0x00 :

    27

    28

    49

    50

 2 - Put the node in operational mode

    51

CAN message (NMT) :

    52

cobid : 0x00

    53

data : 01 03

    54

    55

The node is sending the SYNC every 10 ms

    60

To stop the SYNC : 2 methods

    61

    62

1 - put 0x00000000 at index 1006 subindex 0

    63

2 - put 0x00000080 at index 1005 subindex 0
