Abstract

본 발명은 스캔(SCAN) 방식에 의한 프로그램어블 콘트롤러(이하 PLC)의 스위치 입력방법에 관한 것으로, 특히 다수개의 스위치를 소수개의 PLC입력, 출력카드의 접점을 이용한 스캔(SCAN)방식에 의하여, 그 스위치의 감지신호를 입력받아 처리함으로써, 사용하여야 할 스위치의 갯수가 많아 배선의 처리가 복잡한 문제 및 PLC입력점수의 증가등의 문제점을 해결할 수 있는 스캔(SCAN) 방식에 의한 프로그램어블 콘트롤러의 스위치 입력 방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switch input method of a programmable controller (SCNC) based on a scan (SCAN) method. In particular, a plurality of switches are provided by a scan (SCAN) method using a few PLC inputs and output card contacts. By receiving and processing the detection signal of the switch, the switch input of the programmable controller by the scan (SCAN) method can solve the problem of complicated wiring processing and increase of the PLC input point due to the large number of switches to be used. It is about a method.
