Abstract

PURPOSE:To supplement the loss of supervising data during a CPU system down and to improve the reliability of the system by having a display to collect the supervising data and an accumulating devise independently form the CPU. CONSTITUTION:A system-down is caused to a CPU 1 at a K time zone on L month M day. In this case, the supervising data as of K hours on M day L month J year are uncollected-unstored in a supervising data uncollecting- unstoring time zone registration file 13. During this down period, a display controller 5 and a data accumulating devise 8 are in order and a data collection- storage is executed. When it is restored to a K+5 hours zone on the same day, respective time zones of K-K+4 of the file 13 are initialized as an uncollected-unstored at the time of rising-up. After this, the transfer request of the said data is executed to the device 5 and the device 5 conveys a request to the device 8. The device 8 reads out instructed data from a data file 14 and returns to the CPU 1 through the device 5 after editing. After the CPU 1 stores in data files 11 and 12, executes an information setting of the contents of the data collection-stored effect of the time to the file 13.
