PURPOSE:To provide the system operating information management device restoring only the system operating information on a controlled device requiring restoration in a shortest path. CONSTITUTION:When a fault takes place in a 1st controlled device 11 or the occurrence of a fault in a 2nd controlled device is informed, the 1st controlled device 11 informs a central processing unit 10 of it. The central processing unit 10 informs the 1st controlled device 11 of a system operating information restoration request. When the fault takes place in the 1st controlled device 11, the 1st controlled device 11 reads the system operating information from the 2nd controlled device 12 to restore the system operating information of itself and when the fault takes place in the 2nd controlled device 12, the system operating information of the 1st controlled device 11 is transferred to the 2nd controlled device 12 to restore the system operating information of the 2nd controlled device 12. |
