摘要： A method is described for serial data transmission in a bus system having at least two participating data processing units, the data processing units exchanging messages via the bus, the sent messages having a logical structure in accordance with CAN standard ISO 11898-1. When a first changeover condition is present, then, deviating from CAN, the data field of the messages can include more than eight bytes, the values of the data length code being interpreted, given the presence of the first changeover condition to determine the size of the data field. For forwarding data between the data field and the application software, at least one buffer memory is provided, and, if the size of the data field differs from the size of the buffer memory used, the forwarded quantity of data is adapted at least corresponding to the difference in size between the data field and the buffer memory.

摘要： A subscriber node of a communication system, a communication system and a method for transmitting a message in the communication system. The message is transmitted from a first subscriber node of the communication system via a data bus of the communication system to a second subscriber node of the communication system. An application program of the first subscriber node files the message, that is to be sent, in a message memory, from where it is retrieved by a communication controller, upon a sending command of the application program, and is transmitted via the data bus. In particular in the case of a cancellation of the transmission job, in order to be able to improve the capacity utilization and the efficiency of a host CPU, it is provided that a transmission event for the message, that is to be sent or that has been sent, is stored in at least one transmission event memory, that is functionally separate from the message memory, and that the application program is able to access the data stored in the event memory at any time.
