FIELD: information technology.
SUBSTANCE: present invention relates to network communication technologies. In method access to bus for sending any message is provided to a bus subscriber which becomes sender of said message, according to an arbitration method of corresponding standard ISO 11898-1 on CAN protocol, messages have a logic structure corresponding to CAN protocol standard, that is, consist of a start-of-frame bit, arbitration field, control field, data field, cyclic redundancy check (CRC) field, acknowledge field, and end-of-frame field, function of data transmission is checked during transmission by comparing a sent signal sent to bus connection unit with received signal (CAN_RX) received by the bus connection unit, method is characterised in that a sent signal (CAN_TX_DEL) delayed by a delay time (T_DELAY) compared to sent signal (CAN_TX) is held in sender, and undelayed sent signal (CAN_TX) or delayed sent signal (CAN_TX_DEL) is used for checking correct function of data transmission depending on a switchover.
EFFECT: technical result is faster data transmission in network.
