FIELD: information technology.
SUBSTANCE: present group of inventions relates to transmitting data and can be used for serial data transmission in a bus system having at least two participating data processing units that are bus requesters and exchange massages via the bus, sent messages having a logical structure in accordance with CAN standard ISO 11898-1. Data field of the messages can include, in contrast to CAN standard ISO 11898-1, more than eight bytes, wherein the values of the data length code is interpreted at least partly in a manner deviating from CAN standard ISO 11898-1 to determine the size of the data field. For the forwarding of data between the field data 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 used.
EFFECT: to increase the volume and rate data transmission.
