Abstract

본 발명은 분산제어시스템(DCS)과 하이브레인 프로그래머를 로직 컨트롤러(Hibrain PLC)의 인터페이스방법에 관한 것이다. 본 발명은 분산제어시스템이 하이브레인 프로그래머를 로직 컨트롤러에 연결되는 외부장치들을 제어하기 위하여 제어명령을 발생할 때, 제어명령을 입력받아 일시저장하기 위한 출력메세지버퍼를 설정하고, 출력메세지버퍼로부터의 데이타를 하이브레인 프로그래머를 로직 컨트롤러의 통신모듈로 전송하는 단계, 및 하이브레인 프로그래머를 로직 컨트롤러로에 연결되는 외부장치들로부터 입력되는 데이타를 하이브레인 프로그래머를 로직 컨트롤러의 통신모듈을 통해 전송받을 때, 전송데이타를 입력받아 일시저장하기 위한 입력메세지버퍼를 설정하고, 입력메세지버퍼로부터의 데이타를 분산제어시스템 내부의 메모리테이블에 기록하는 단계를 포함한다. 따라서, 프로그래머블 로직 컨트롤러가 지금까지의 제어기기의 의미에서 한층 발전하여 컴퓨터에 의한 통합생산시스템에 구축하는 데에 중요한 역할을 담당할 수 있도록 하는 효과를 갖는다.The present invention relates to a method of interfacing a distributed control system (DCS) and a hybrid programmer to a logic controller (Hibrain PLC). When the distributed control system generates a control command to control the external device connected to the logic controller, the distributed control system sets an output message buffer for receiving and temporarily storing the control command, and the data from the output message buffer. Transmitting the high-lane programmer to the communication module of the logic controller, and receiving the input data from external devices connected to the high-controller programmer to the logic controller through the communication module of the logic controller. Setting an input message buffer for receiving and temporarily storing data, and writing data from the input message buffer to a memory table inside the distributed control system. Therefore, the programmable logic controller has an effect of being able to play an important role in the development of the integrated production system by computer by further developing in the sense of the control device up to now.
