In a bus system that includes at least two subscribed data processing units that exchange messages via a bus in a serial data transmission, the transmitted messages are of a logical structure that includes a start-of-frame bit, an arbitration field, a control field, a data field, a CRC field, an acknowledge field and an end-of-frame sequence, the control field including a data length code, which contains information regarding the length of the data field. The messages are constructed such that the data field of the messages can include more than eight bytes, and, in a method of such serial data transmission, the values of the data length code are interpreted at least partially in a manner that deviates from the CAN standard ISO 11898-1 for determining the size of the data field. |
