<p>PROBLEM TO BE SOLVED: To make gatherable, accumulable, and retrievable a time-series information of production system by making use of a hyperlink by segmenting time- series information of a time zone out of accumulated time-series information and managing the segmented time-series information by linking it to event information corresponding to an occurring event. SOLUTION: An information management system is constituted by connecting programmable controllers 10-1 and 10-2, a personal computer 20, and a Web client 30 to the Internet 50. In this constitution, meaningful time-series information on the time base of the production system is acquired and accumulated and the occurrence of an event in the production system is detected to generate time-zone information having specific time width corresponding to the occurrence of the detected event. The time-series information of the time zone corresponding to the generated time-zone information is segmented from the accumulated time-series information and then managed by being linked to the event information corresponding to the occurring event.</p> |
