A Programmable Automation Controller (PAC) has been developed by Turbotek Co., Ltd. The developed system has multi-domain functionality-including sequence control, motion control and HMI- on a single platform. The PAC also has a common development platform for the design and integration of multi-domain automated systems. Since hardware of the developed system has modular architectures, performance and specification of the controller are determined by combination of specific modules. The developed system employs de facto standards such as OPC interface that allow users to easily exchange data as part of networked multi-vendor systems.

This paper proposes a machine vision module for PLCs (Programmable Logic Controllers). PLC is the industrial controller most widely used in factory automation system. However most of the machine vision systems are based on PC (Personal Computer). The machine vision system embedded in PLC is required to reduce the cost and improve the convenience of implementation. In this paper, we newly propose a machine vision module based on PLC. The image processing libraries are implemented and integrated with the PLC programming tool. In order to interface the libraries with ladder programming, the ladder instruction set was also designed for each vision library. By use of the developed system, PLC users can implement vision systems easily by ladder programming. The developed system was applied to sample inspection system to verify the performance. The experimental results show that the proposed system can reduce the cost of installing as well as increase the ease-of-implementation.

어느 정도 규모를 가진 실험 설비를 자동화하기 위해서 분산 I/O를 지원해 주는 자동화 컨트롤러를 사용하는 것이 편리하며 이러한 용도로 PLC(Programmable Logic Controller), PAC(Programmable Automation Controller) 등을 사용하고 있다. 하지만 기능적으로 필요로 하는 I/O 이외에 전원장치, 백프레임, 그리고 메인콘트롤러 등의 항목이 추가된다. 이러한 제한은 필요로 하는 자동화 대상인 설비의 I/O의 접점수가 많지 않지만 이들을 분산하여 설치될 필요가 있을 경우 전체 시스템을 자동화 하는데 소요되는 비용을 필요 이상으로 높이게 된다. 본 연구는 현재 한국원자력연구원에서 시험 운전 중인 TS-NBI 장치의 자동화에 이용할 목적으로 자동화 대상 설비의 I/O 접점수가 많지 않지만 분산 I/O로 구성하여야 하는 경우에 적용할 해결책을 찾기 위해서 수행 하였다.
