<p>PURPOSE:To exactly analyze abnormality, and to early restore a device by preparing a data reproduction file only at the time of periodically fetching device monitoring data, and detecting the abnormality. CONSTITUTION:Device monitoring raw data are periodically collected from a communicating means in a raw data buffer 30 in the fixed time by referring to a raw data buffer management table 28 with a data fetching means 26. At the time of the end of the collection, when the abnormality is detected by an abnormality judging means 34, the raw data buffer 30 is synthesized with the raw data buffer management table 28, and a data reproduction file 46 is prepared. Then, abnormality data are developed on a restoration data buffer management table 40 and a restoration data buffer 42 from the data reproduction file 46, the reproducing method of the abnormality data is instructed by a reproduction instructing part 44 by an input from a key 14 or the like, the destination of a data fetch is decided by a flag 48, the device monitoring data for abnormality generation are fetched, and displayed at a display device 12.</p> |
