산업 자동화 시스템을 위한 안정된 인터페이스 기술 개발 및 구현 = Development and implementation of a stable interface technic for industrial automation system

다국어 초록 (Multilingual Abstract)

In general, industrial automation systems(IASs) deals with very sensitive data about operation and production and operates at the poor environment. IASs consist of a control part and a GUI(Graphical User Interface) part. The control part mainly takes charge of controling each operational device and the GUI part takes charge of communication mode for data and controls between the user and IAS. Thus communication information between the two parts includes production, control and operation information. It is very important to make sure that the GUI correctly processes and analyses the communication information, because GUI delivers such information between the operation part and the user. There has been difficulties in implementing GUI communication part without losing such important operational data.
Therefore this paper presents development and implementation of a new stable processing method of GUI communication using a combined mechanism of message interrupt and timing. Several systems with this method have been implemented and tested in various conditions, and they show us that lose of the unstable operational data can be prevented.
