ABSTRACT:
This invention relates to a loop transmission system which has a plurality of stations connected to a loop transmission path to transmit data among the stations. In the transmission frame to be sent out from the sending station, specific information is included for identifying each frame and this information is held in the sending station. When the transmission frame returns to the sending station after being transmitted through the loop transmission path, the specific information in the frame is received and compared with the information held in the station and, if they coincide, it is decided that the transmission frame has been correctly received by the intended receiving station.
