PURPOSE: To repair data in a backup area by detecting data destruction in the backup area caused by power source interruption for executing high- accuracy learning value control and abnormality detection. CONSTITUTION: The backup area is composed of areas for access equipped with KG1-16 and KGSUM for storing control data and areas for temporary save equipped with KGADR, KGVAL and KGSUMVAL for temporarily storing a learning value and an integrated value using that learning value, and the backup area is updated into an area for access shown by address data at every timing. This area for access is compared with the area for temporary save and when the destruction of stored contents in the area for access is detected, the stored contents in the area for access are repaired based on the stored contents in the area for temporary save. |
