Kind Code:
A
Abstract:
PURPOSE:To execute useful equalizing of a fixed data when one side system is shifted from a stop condition to a dependent mode by installing a preserving area of renewed history information of the fixed data in an auxiliary memory device, and storing the renewed data beforehand. CONSTITUTION:In the first system and second system auxiliary memory devices 311 and 321, history information preserving areas 3111 and 3211 are installed, and at these areas, the renewed history information of the fixed data is preserved. When the second system is shifted from a stop condition to the dependent mode, first, a fixed data renewed history information of an area 3111 in the first system device 311 which is a main mode, is taken out through a system linking device 4. Next, the presence and absence of preserving the fixed data renewed history information are decided, and in case of the preservation, the fixed data of an area 3211 in the unit 321 in a time series in the order in accordance with the fixed data renewed history information are renewed and shifted to the dependent mode. Thus, areas 3111 and 3112 are installed, the changed part of the fixed data is stored beforehand, and thereby, when the one side system is shifted from a step condition to a dependent mode, the fixed data can be usefully equalized.
