METHOD AND APPARATUS FOR PREDICTING ERROR IN PROCESS CONTROL NETWORK

PURPOSE: A method and an apparatus for predicting failure in a process control network are provided to predict the probability of the same failure by measuring actual generation period according to failure. CONSTITUTION: A packet receiver(112) of a failure information providing module(110) collects...

Zusammenfassung:	PURPOSE: A method and an apparatus for predicting failure in a process control network are provided to predict the probability of the same failure by measuring actual generation period according to failure. CONSTITUTION: A packet receiver(112) of a failure information providing module(110) collects packets generated in a process control network. A failure determining unit(114) determines failure generated through packet analysis. A failure determining unit records failure information. A failure predicting module(120) predicts the probability of same failure occurrence using failure information. A failure expression unit(122) constitutes failure expression based on the failure information.
