Abstract

PURPOSE:To standardize a system and to increase the response performance, by rearranging the information received irregular addressing in a physical way to a normalized logic address based on a certain rule. CONSTITUTION:The plant information is fetched through a data fetching part 5 and compared with the preceeding data which is fetched into a physical address data table 14. When a change is detected with some information, the indication flag is set at the corresponding address on the indicated information table 15 to show the occurrence of a state change in the form of binary data. A state change detecting part 6 retrieves the table 15 and extracts the word address to which the indication is set to obtain a physical address. Then the logic address corresponding to the physical address is drawn out in reference to a comparison number table, and the preceeding data given from a logic address data table 16 is compared with the fetched data. When a change is detected, the present data is added to the state change detecting time to be fed to a state change analyzing part 7 and each processing part 17 in the form of the event information. The part 7 analyzes the state change and supplies the result of analysis to the table 14.
