Abstract

A method for serial data transfer in a bus system having at least two bus subscribers that exchange messages via the bus, the transmitted messages having a logical structure according to CAN standard ISO 11898-1, the logical structure encompassing a start of frame bit, arbitration field, control field, data field, CRC field, acknowledge field, and end of frame sequence, the control field encompassing a data length code that contains an information item regarding the length of the data field. The method is characterized in that when a first marker (EDL) is present, the control field of the messages, divergently from ISO 11898-1, encompasses more than six bits; the first marker (EDL) being implemented by way of a recessive bit in the control field, and when the first marker is present, the recessive bit of the first marker (EDL) being followed, in all data messages, by at least one dominant bit.
