<P>PROBLEM TO BE SOLVED: To provide a monitoring control system for reducing the workload of an operator and improving reliability by automatically taking over control logic data when a system such as an operation system and a standby system is switched. <P>SOLUTION: A monitoring control system comprises: a pair of logic control units 11a and 11b one of which is configured as an operation system, and the other of which is configured as a standby system for performing the monitoring control of the operating state of a control device 2 to be monitored based on a prescribed control logic; a system switching control unit 13 for, when an abnormal state is detected by the logic control unit 11a or 11b designated as the operation system, switching the logical control unit 11a or 11b designated as the operation system to the standby system, and for switching the logic control unit 11a or 11b designated as the standby system to the operation system; and control logic data guaranteeing means 16 for shifting the control logic data of the logic control unit 11a or 11b designated as the operation system to the logic control unit 11a or 11b designated as the standby system under the system switching control of the system switching control unit 13. <P>COPYRIGHT: (C)2012,JPO&INPIT |
