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 having an information item regarding the data field length. When a first marker (EDL) is present, the control field of the messages, divergently from the CAN standard ISO 11898-1, encompasses more than six bits; when the first marker (EDL) is present, the control field of the message is expanded to include at least one further bit (ESI); and the further bit (ESI) or one of the further bits causes an information item regarding the 'error passive' state of the bus subscriber to be integrated into transmitted messages.
