CAN-ID
1166
Depending of the CAN-ID the following CAN identifiers are free available for the data transfer:
CAN-ID base CAN-ID extended
11 bits 29 bits
2 047 CAN identifiers 536 870 912 CAN identifiers
Standard applications
Motor management (SAE J1939),
Truck & Trailer interface (ISO 11992)
NOTE
In some devices the 29 bits CAN-ID is not available for all CAN interfaces, data sheet.

Legend:
SOF = Start of frame
Edge of recessive to dominant
RTR = Remote transmission request
dominant: This message sends data
recessive: This message requests data
IDE = Identifier extension flag
dominant: After this control bits follows
recessive: After this the second part of the 29 bits identifier follows
SRR = Substitute remote request
recessive: Extended CAN-ID: Replaces the RTR bit at this position
