PURPOSE:To improve the function of a state supervisory system by collating the factor of operation state change for number of facility to be supervised and controlled with a pattern table to decide immediately. CONSTITUTION:A remote supervisory and controlling equipment TC inputs a state at every supervisory and controlling point of the facility SC to be supervised and controlled as contact information to supervise and control the change. When a change in the state is detected, a word address, bit address, and the state value succeeded the change corresponding to the contact information are transmitted to a central processor CPU. The central processor CPU makes a comparison with a flag state in a memory MEM corresponding to the transmitted address. When the state change is judged, to generate, the flag in the memory MEM is rewritten into the state succeeding the change. The flag state of additional information is also checked and the decision on the factor is made to output the result to a display CRT and a printer PRT. |
