Abstract

PURPOSE:To enhance the reliability, the flexibility and the cost performance each of the remote control system, by connecting plural numbers of slave stations plus the main and secondary master stations to the 1st and 2nd down-circuits. CONSTITUTION:Main master station 21 plus slave stations 221-22n are connected to the 1st down-circuit 23 as well as to secondary master station 24. In the same way, main master station 21 is connected to station 24 as well as to the 2nd down- circuit 25 of each slave station. If the station address is allotted to both stations 21 and 24 like each slave station, station 24 can also receive the control signal when station 21 transmits the control signal to each slave station. On the other hand, station 21 can also receive the control signal when station 24 transmits the control signal to each slave station. Accordingly, the down-control signal can always be monitored at stations 24 and 21 each to increase the checking functions to the answer given from each slave station. And down-circuits 23 and 25 function to connect between stations 21 and 24 when the fault occurs to up-circuits 26 and 27 each. Thus the transfer of the data signal becomes possible.
