The extended frame is the same as the above standard frame, except for the differences described below: SRR bit: The Substitute Remote Request bit is transmitted in extended frames at the position of the RTR bit in standard frames. It is always recessive. WebWhat is a CAN frame? Communication over the CAN bus is done via CAN frames. Below is a standard CAN frame with 11 bits identifier (CAN 2.0A), which is the type used in most cars. The extended 29-bit identifier frame (CAN 2.0B) is identical except the longer ID. It is e.g. used in the J1939 protocol for heavy-duty vehicles.
