Abstract
PURPOSE:To improve the reliability of an important line by adding a transmission flag and a reception flag to a frame, sending the result so as to attain the presence of plural stations having one and same station addresses on the transmission line. CONSTITUTION:The transmission flag and the reception flag are added to the frame and one and same station address is added to a predetermined station, a control station sets the sender and destination station address, the flag is made ineffective and sends the result to the transmission line. On the other hand, each station is provided with an address/flag detection means 5, a flag state operation means 6 and a select means 1 and when the station address of sender or destination in the reception frame is coincident with the station address of its own station and the corresponding flag is effective, the flag is made ineffective, the data to be sent is inserted to the reception frame or after the data of the reception frame is fetched, it is sent to the transmission line.
