Abstract
A monitoring device is mounted in each of a plurality of operational systems constituting a fault-tolerant system. The plurality of operational systems have an identical configuration including a processor system. The monitoring device includes a processor. The processor executes instruction to read data from a predetermined storage area in a memory of an accessory device to be monitored, connected to the processor system. The processor further executes instruction to compare the read data with reference data held in advance. The processor further executes instruction to separate the processor system connected to the accessory device to be monitored from the fault-tolerant system when the read data is different from the reference data.
