Abstract
An information processing device includes control circuitry. The control circuitry is configured to store, in a first memory, record information formed each time a predetermined event occurs in a device and perform an update process of successively updating an old piece of record information with a new piece of record information in the record information stored in the first memory; transmit the record information stored in the first memory via a first signal line; transfer communication abnormality record information stored in the first memory to a second memory, which is configured not to update record information, and store the communication abnormality record information in the second memory when a communication abnormality signal of the first signal line is supplied via a second signal line; and transmit the communication abnormality record information stored in the second memory via the first signal line when communication of the first signal line is restored.
