<p>PURPOSE:To enable free selection of rearranging and testing time of facility data regardless of working time of hardware by checking input of incorrect facility rearrangement data when a simulated facility data base is developed based on facility rearrangement data and current facility data base. CONSTITUTION:A system management unit 3 has facility data managing function and recognizing/switching function of main and sub systems of computors 1, 2, where a monitoring/controlling object, i.e., facility data, is stored as a facility data base in a memory 4 then a computor 1 copies the facility data base into the memory 10 thereof and performs specific data processing. Current data base and rearrangement data concerning to 1st to n-th works are combined in the data developing section 7 of the system managing unit 3 then a future data base is simulated and stored in a memory 6. Thereafter the simulated data base is copied into the memory 11 of the computor 2 and employed at the simulation executing section 8 in the computor 2.</p> |
