터치스크린과 웹을 이용한 공장자동화의 PLC 제어 시스템 구현

Abstract

Manufacture automation technology is continued and advanced to produce the products on the factory automation area. And according to the development of the controlling area, the manufacture automation technology has high performance and accuracy those were really difficult the implementation. Also, the controlling of manufacturing process is to be a gigantic system and to control the system which has the interconnection. In this paper, the authors proposed the PLC controlling of factory automation on internet web browser. At the remote control of long distance, Active-X control that is used between the client and server PC for the authentication. Bi-directional communication protocol of PLC written and set to the administrator system of the web server with Active-X control program. The client PC for monitoring on the web browser sends some commands to the server PC which guards and controls PLC. As a result, the authors confirms that stepping motor connected to PLC is correctly operated according to the PLC controlling commands which are given on the web browser of the client PC.
