摘要
A control system 10 has information acquisition apparatuses 2-1 2-n to acquire maintenance management information having a unit of a predetermined time period, and a control apparatus 1 configured to collect maintenance management information pieces from the information acquisition apparatuses 2-1 2-n. The information acquisition apparatuses 2-1 2-n each includes a first and second storage unit 242, 243. The maintenance management information stored in the first storage unit 242 is saved into the second storage unit 243 in response to a save command from the control apparatus 1. After maintenance management information pieces are saved from a first storage unit 242 into a second storage unit 243 in all of the information acquisition apparatuses 2-1 2-n, the control apparatus 1 collects the maintenance management information pieces saved in the second storage unit 243, from the respective information acquisition apparatuses 2-1 2-n.
