題があった。(Problems to be Solved by the Invention) In the conventional supervisory control system described above, as the number of remote supervisory control devices increases, the cycle in which the main supervisory control device manages the remote supervisory control devices becomes longer, and the cycle becomes shorter. When the length of the transmission line is limited, the number of units that can be used is limited, and since the backup transmission line is rarely used, working and backup transmission lines are set up within the own system, such as in optical transmission systems. The problem with this system was that the transmission path was used inefficiently.
