Abstract
본 발명은 피엘씨 프로그램 수정방법에 관한것으로, 종래에는 피엘씨로 생산라인을 제어하는 상태에서 전체시스템의 프로그램인 피엘씨 프로그램 수행중에 일부생산라인 구동에 해당하는 사용자프로그램일수를 수정할 경우 전체 시스템에 해당하는 피엘씨 프로그램을 중단후 일부를 수정하여 프로그램 수정에 따라 전체 생산라인이 중단되어 생산성 저하로 피엘씨의 성능을 저하시키는 문제점이 있었다.The present invention relates to a method for modifying a PLC program, and in the related art, when a user program number corresponding to driving of a part of a production line is modified during the execution of a PLC program, which is a program of the entire system, while the production line is controlled by PLC. After stopping the corresponding PRC program, a part of the program was modified and the entire production line was interrupted according to the program modification.
본 발명은 상기와 같은 종래의 문제점을 감안하여 생산라인에서 전체시스템을 제어하는 피엘씨 프로그램 수행도중 생산라인 일부에 해당하는 사용자 프로그램의 일부를 수정할때 프로그램을 저장하는 메모리의 일부에 수정명령, 수정하고자하는 명령, 수정어드레스를 정하여 수정하므로 전체시스템 중단없이 일부라인 수정이 가능하여 피엘씨의 성능을 향상하는 효과가 있다.The present invention has been made in view of the above-mentioned problems in the production line during the execution of the PLC program controlling the entire system in the production line when modifying a part of the user program corresponding to a part of the production line, the correction command, modification to a part of the memory to store the program It is possible to modify some lines without interruption of the whole system by modifying the desired commands and modification addresses, thereby improving the performance of PL.
