Patent number: 9020614Abstract: A plant control system carrying out a single shot output without adding a program concerning signal transfer between a supervisory control device and a programmable logic controller to the supervisory control device and the programmable logic controller. The plant control system includes a single shot output functioning section which causes a SCADA system connected to a programmable controller for controlling the plant to send a control signal corresponding to control content of a selected plant to the programmable controller, and, thereafter, to send an erasure signal for erasing the control signal held in the programmable controller to the programmable controller. The single shot output functioning section is outside of the SCADA system and outside of the programmable controller.Type: GrantFiled: September 28, 2009Date of Patent: April 28, 2015Assignee: Toshiba Mitsubishi-Electric Industrial Systems CorporationInventors: Hiroyuki Fujieda, Akira Nojima
