PURPOSE:To perform activated maintenance by switching a control part to a control state by an ordinary processing after recovering a fault by monitoring the occurrence and recovery of the fault in the control part. CONSTITUTION:The control part 2 is duplexed by control modules 3 and 4, and performs the control of data transfer performed among processing modules 11A-11N and the detection of the fault. A control monitoring part 6 operates the control modules 3 and 4 with the same timing by managing the operations of the control part 2 and a switching part 5, and makes the control part 2 and the switching part 5 perform the control of the data transfer by ordinary processing states after the fault is recovered by a monitoring the fact of the occurrence and recovery of the fault in the control part 2. In such a way, it is possible to perform the activated maintenance by recovering the module in which the fault occurs during the execution of the control. |
