PURPOSE:To perform an appropriate restoring process to a fault when the fault occurs in an operating machine by restarting the operating machine and, when the operating machine cannot be restored from the faulty state even when the restarting is repeated by a prescribed number of times, switching the machine to be operated to a stand-by machine. CONSTITUTION:When a fault occurs in an operating machine, the operating machine is restarted and, when the operating machine normally operates, the system operation is continued under the same condition. When the operating machine does not make normal operation even when the restarting is repeated by a prescribed number of times, the machine to be operated is switched to a stand-by machine. Therefore, the operation can be restarted without switching to the stand-by machine when the operating machine is stopped by a transitory fault. Moreover, when the fault is not a transitory one, the operation can be restarted with the stand-by machine. |
