FIELD: radio engineering, communication.
SUBSTANCE: invention relates to data transmission systems. A message (7) is transmitted by a first subscriber node (3) of a communication system (1) via a data bus (2) of the communication system (1) to a second subscriber node (3) of the communication system (1). An application program (5) of the first subscriber node (3) stores the message (7) to be sent in message memory (11, 12), from where it is retrieved by a communication controller (4), upon a sending command of the application program (5), and is transmitted via the data bus (2). The subscriber node (3) also has at least one transmission event memory (13) that is functionally separate from the message memories (11, 12), in which a transmission event for at least one message (7) to be sent or which has been sent is stored, wherein the transmission event indicates cancellation of a first transmission task, and the event memory (13) stores a time mark indicating when the event occurred.
EFFECT: faster execution of successive transmission tasks in case of cancellation of one transmission task.
