<p>Provided is a plant control system capable of outputting a single shot without adding a program that is associated with signal transmission to a supervisory control device and a programmable logic controller. Thus, the plant control system is configured to comprise a single shot output function section for transmitting a control signal, which corresponds to the control content of a plant selected in connection with an SCADA connected to the programmable controller that controls the plant, to the programmable controller, and then transmitting a cancellation signal that cancels the control signal retained by the programmable controller to the programmable controller, wherein the single shot output function section is provided outside the SCADA and outside the programmable controller.</p> |
