Identifier extension bit in can
WebThere are three main differences between CAN FD and Classical CAN: Bit Rate Switching (BRS); maximum size of the data payload; the coverage of the CRC. The first two of these will be identified and explained first, because these two are directly visible to, and controllable by, the systems engineer. WebThe 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. Note that the CAN ID and Data are …

Web1 jun. 2012 · To support these efforts, the CAN protocol was extended by the introduction of a 29-bit identifier. This identifier is made up of the existing 11-bit identifier (base ID) and an 18-bit extension (ID extension).
