The maintenance tools 120-12n are connected over a maintenance network 12. The maintenance tools 120-12n each have a function of serving as a management server autonomously. One of the maintenance tools 120-12n serves as a maintenance tool (management server) 12m, which manages multiple pieces of data set for maintenance on the control apparatuses 111-11n, and distributes the multiple pieces of set data to the other maintenance tools 120-12n. The other maintenance tools 120-12n store the multiple pieces of set data. |
