Abstract

본 발명은 프로그래머블 로직 컨트롤러(Programable Logic Controller; PLC)용 장거리 데이타 전송 및 교환 장치에 관한 것으로, 상세하게는 PLC 시스템과 모뎀을 접속하여 장거리 데이타 전송 및 데이타 교환에 사용할 수 있는 프로그래머블 로직 컨트롤러용 장거리 데이타 전송 및 교환 장치에 관한 것이다.The present invention relates to a long distance data transmission and exchange device for a programmable logic controller (PLC), and more particularly, to a long distance data for a programmable logic controller that can be used for long distance data transmission and data exchange by connecting a PLC system and a modem. It relates to a transmission and exchange device.

즉, 본 발명에 따른 프로그래머블 로직 컨트롤러용 장거리 데이타 전송 및 교환 장치는 PLC와 콤퓨터의 통신 유니터에 범용의 시리얼 통신 방식의 RS-232나 RS-422를 설치하고 그 사이에 모뎀을 설치하여 일반공중 회선을 이용하여 장거리 통신을 함으로써, 먼 거리에서도 쉽게 PLC 정보를 모니터링 하거나 데이타를 송수신할 수 있는 장점이 있다.That is, the long-distance data transmission and exchange apparatus for a programmable logic controller according to the present invention is to install a general-purpose serial communication RS-232 or RS-422 in a communication unit of a PLC and a computer, and a modem between them. By long-distance communication using a line, there is an advantage that it is easy to monitor PLC information or transmit / receive data even at a long distance.
