    摘要: A replicated controller and a fault recovery method therefor which can restore a faulty system to a normal state without interrupting operation of an equipment, even in an equipment controller performing processing with short operating periods.
    In a fault recovery method for a replicated controller, control data is divided into a plurality of blocks on the basis of dependency of the blocks, and a plurality of blocks are transferred in a sequential order of superiority of the dependency from the normally operating system to the faulty system in a period over a plurality of operating periods. BY this, even in an equipment controller performing processing at a short operating period, the system, in which failure is caused, can be restored into normal state without interrupting operation of the equipment.
