Abstract

PURPOSE: To establish the data delivery system with versatility and extendability, by providing the circuit dividing the information flowing in the delivery line into channels and the circuit controlling the information split an by exclusively using the channels each unit.
CONSTITUTION: The delivery lines are two and they have signals flowing conversely with each other, and normally, one is used as spare loop, preventing the system down. The master station MST performs the monitor of delivery line and the operation of restoration at failure occurrence. The computer CPU, terminal unit DEV and process input and output unit PIO etc. are connected to the station RST. The repeater REP of station has two transmitter and receiver, and basic clock is reproduced from the reception signal, and the control circuits 9 to 11 are present in the channel divided with the channel dividing circuit 8. The circuits 9 to 11 controls the information so that it is constituted in CPU, DEV, and PIO etc. connected with optimum delivery method. Thus, it is equivalent to the presence of n sets of delivery lines and the extendability can be given.
