The Institute of Computer-Architecture and System-programming (ICAS) of the University of Kassel has examined the CAN XL data link layer protocol specified in CiA 610-1. More than half of a year, Prof. Dr. Josef Börcsök and his team investigated in the evaluation of the error detection mechanisms provided by the CAN XL protocol. The final research report comprises a qualitative evaluation of the residual error probability, too.
CAN in Automation (CiA) members have developed the CAN XL data link layer specification. It is available in the CiA 610-1 CAN XL data link layer and physical signaling document.
