PURPOSE:To transmit and receive a data between optional stations by transmitting and receiving a signal to constitute the data to and from the channel at a constant speed, generating the data to the input device, and reading the data corresponding to the output device, by respective stations. CONSTITUTION:To a loop-shaped channel L, plural stations S1-Sn are dispersed and connected. AT the connecting point of the channel L and a station Si, the signal of the channel L is fetched into a controller SC, a series of processing is executed, and the signal is returned to the channel toward the adjoining station. Respective stations have (m) pairs of the slot composed of pair >=pair of input device DI and output device DO. The input device DI of a slot Tx of a station SK receives the input signal from a control device C1, and sends the output signal through the output device DO of a slot Ty of a station Sl to a control device C2. Thus, at plural pairs of the assembly of the input output devices DI and DO, the data can be transmitted and received without the indication of the high order station. |
