MONITORING CONTROL SYSTEM

PROBLEM TO BE SOLVED: To provide a monitoring control system that can omit arrangement of manpower for table maintenance of a control relay point and an opposite test, and cut unnecessary information in an operation control network.SOLUTION: In a monitoring control system, a monitoring control device 23 at a B control point compares information received from information collecting and distributing devices 43, 53 at an A control relay point 40 and a B control relay point 50 with a reception table in which information to be received from the information collecting and distributing devices 43, 53 is preset. When the information set in the reception table is not coincident with the received information, the monitoring control device 23 detects the difference in information, and transmits a request for nullifying the difference to the information collecting and distributing device 43 at the A control relay point 40. When receiving the request from the monitoring control device 23 at the B control point 20, the information collecting and distributing device 43 at the A control relay point 40 corrects a distribution destination table so as to nullify the difference on the basis of the request.
