ある。However, in conventional supervisory control systems, the processor of the upper supervisory control device 10'' issues a transmission request to each lower supervisory control device using a polling method, collects monitoring information,
In addition, control information must be sent to each lower-level supervisory control device, which imposes a heavy load and cannot be done at high speed.As the number of lower-level supervisory control devices increases, the polling method is used, so monitoring information cannot be sent from all lower-level supervisory control devices. It takes time to collect
There is a problem that high speed is lost. Fatherhood monitoring control device 1
Since there is a limit to the number of input ports for 0', there is a problem in that only lower-level monitoring and control devices within the number of input ports can be connected.
