Abstract In a bus system having a plurality of instruments linked to each other, the invention proposes a method which avoids useless data transmission or useless occupation of a data transmission line. A data transmission line is established for starting receipt/transmission of data after available instruments for the transmission/receipt of the date are identified. During the transmission of the data, the enable and disable state of transmission/receipt of the data is monitored and if desired, the data transmission is broken.
