Abstract
Official abstract text for this publication.
Information processing system including: a plurality of process control units storing process data including present value and time-series data or historical data, and a plurality of data collection units collecting and processing data from the process control units. The data collection units each include: a first dynamic management section managing access and exit of the data collection unit of interest to and from the information processing system and managing operating status of all data collection units currently accessing the information processing system; a second dynamic management section managing addition and removal of process control units to and from the information processing system; and a charge determination section determining process control units to be taken charge of by the data collection unit of interest based on first identification information allocated to each of the data collection units and on second identification information allocated to each of the process control units.
First claim
Opening claim text (preview).
What is claimed is: 1. An information processing system comprising: at least one micro-processor unit (MPU) and memory implementing: a plurality of process control units which store process data including present value and time-series data or historical data; and a plurality of data collection units which collect the process data from the plurality of process control units over a network and which process the collected process data; wherein the at least one micro-processor un…
