PURPOSE:To decrease the receiving time of a confirming packet at a transmitting node and at the same time to facilitate the data transfer procedure, by converting a transmitting packet into a confirming packet at a transmitting node and then transmitting the confirming packet after inserting the receiving result information into the final word. CONSTITUTION:A packet format is formed with a packet control word field A, a data word field B, a receiving result field C and an error detecting code field D. The data transmitted from a transmitting node 30 are fed and stored to a receiving node 8. Then a confirming signal transmitting circuit 5 is started, and the receiving packet is converted into a confirming packet. Then the results of a receiving information register 6 and an error detecting circuit 4 are inserted into the field C of the confirming packet. Furthermore a confirming packet added with the field D is transmitted to a common bus 1 through a driver circuit 7. |
