Abstract
피엘시(Programmable Logic Controller)와 컴퓨터 사이의 통신 상태 진단 방법을 개시한다. 이 진단 방법은, 컴퓨터에 의하여 실행되는, 피엘시(PLC)와 상기 컴퓨터 사이의 통신 상태 진단 방법에 있어서, 상기 피엘시(PLC) 내의 중앙 처리 모듈 및 통신 제어 모듈의 경보 발생 여부를 확인하는 제1단계; 상기 제1단계에서 경보가 발생되면, 그 내용을 사용자가 알 수 있도록 표시하는 제2단계; 상기 제1단계에서 경보가 발생되지 않으면, 소정의 검사 루틴을 생행시키는 제3단계; 및 상기 제3단계에서 상기 중앙 처리 모듈 및 통신 제어 모듈의 에어 코드가 입력되면, 그 내용을 사용자가 알 수 있도록 표시하는 제4단계를 포함한 것을 그 특징으로 한다. 이에 따라 통신 과정에서 발생되는 각종 에러를 사전에 예방하여, 효율적인 통신을 수행할 수 있다.A method of diagnosing communication status between a programmable logic controller and a computer is disclosed. This diagnostic method is a method for diagnosing a communication state between a PLC and a computer, which is executed by a computer, comprising: checking whether or not an alarm occurs in a central processing module and a communication control module in the PLC. Stage 1; A second step of displaying the contents so that the user can know when an alarm occurs in the first step; A third step of executing a predetermined inspection routine if an alarm is not generated in the first step; And a fourth step of displaying the contents of the central processing module and the communication control module when the air codes are input, so that the user can know the contents. Accordingly, various errors generated in the communication process can be prevented in advance, thereby enabling efficient communication.
