FAILURE RECORDING DEVICE, AND FAILURE RECORDING METHOD

摘要

There is provided a failure storage device capable of storing failure details and data to carry out failure determination more accurately while preventing an increase in storage capacity of data with regard to failures. The failure storage device includes a failure storage control unit (3) configured to, when a failure determination unit (2) detects a failure of a target to be controlled, carry out failure storage processing to select data to be stored depending on failure details of the detected failure and store the selected data in a failure analysis data storage unit (33) and a failure name storage unit (35) as storage means, wherein, in the failure storage processing, when several failures are detected within a prescribed period of time, the failure storage control unit (3) stores failure details of an initial failure in the failure name storage unit (35), stores data selected in accordance with the failure in the failure analysis data storage unit (33), and stores only failure details of other failures detected after the initial failure in the failure name storage unit (35).
