CAN XL as a backbone network in off-highway and off-road vehicles
CAN XL is the third generation of CAN protocols, developed for backbone networks. It provides the capability to run several applications in parallel, which allows the implementation of multi-protocol stacks, e.g. CANopen (FD), J1939, and proprietary ones. The CAN XL protocol supports data field lengths of up to 2048 bytes. This enables the running of TCP/IP on CAN XL networks. The physical layer is scalable and features a maximum bit-rate of 10+ Mbit/s. The function of the CAN-ID as specified in classical CAN and CAN FD has been separated in CAN XL (priority and acceptance field).
