MONITORING CONTROL SYSTEM

PURPOSE:To provide a monitoring control system which can surely and easily recognize the changing contents of the operating conditions regardless of the changing frequency. CONSTITUTION:When a monitoring control system is operated, a central processor 10 copies the system operating conditions stored in a master memory 11 to an operation memory 12. The memory 12 holds variably the system operating conditions. Then the processor 10 automatically compares the present system operating conditions stored in the memory 12 with the initial operating conditions of the system stored in the memory 11 when a change list is requested by an operator during the system operation, e.g. at an optional time point or when a changing operation is over. The processor 10 extracts the different points of the operating conditions based on the result of comparison to show these points at a display part 15 or to print them out at a print part 17 as the changing contents.
