Abstract

본 발명은 프로그래머블 로직 콘트롤러(PLC)의 어드레스변경장치에 관한 것으로, 종래에는 입,출력유니트의 접점중 몇 개가 고장이 났을 경우 입,출력유니트 전체를 교체하고 모든 프로그램도 바꾸어야 하므로 많은 시간이 소비되고 즉시 운전할 수도 없는 문제점이 있었다.The present invention relates to an address change device of a programmable logic controller (PLC). In the related art, when some of the contacts of an input / output unit have failed, the entire input / output unit must be replaced and all programs must be changed. There was a problem that can not drive immediately.

따라서 종래의 문제점을 해결하기 위하여 본 발명은 입력 및 출력유니트 중 단 몇 개의 접점(또는 입출력포트)이 고장이 발생하였을 경우 입력 및 출력유니트를 교체하거나 사용하지 않은 접점들을 사용하기 위해 모든 프로그램을 바꾸거나 할 필요없이 사용자가 스위치를 통해 입력 및 출력어드레스를 재구성할 수 있도록 하여 즉시 운전이 가능하도록 하였다.Therefore, in order to solve the conventional problems, the present invention replaces all programs to replace the input and output units or to use the unused contacts when only a few contacts (or input / output ports) of the input and output units fail. The switch allows the user to reconfigure the input and output addresses via a switch, enabling immediate operation.
