Abstract

본 발명은 프로그램 스텝을 지정하는 렁 번호를 저장하기 위한 렁 정보 메모리를 이용하여 인접하지 않은 두 개 이상의 프로그램 스텝을 동시에 탐색할 수 있을 뿐만 아니라, 비교할 수 있게 함으로써 탐색코자 하는 프로그램이 여러 곳에 분산되어 있더라도 그 부분에 해당하는 렁번호만을 지정하여 동시에 탐색할 수 있어 프로그램의 에러수정 및 필요한 프로그램의 삽입이 용이하도록 하기 위한 것이다.The present invention not only searches for two or more non-contiguous program steps simultaneously by using the rung information memory for storing the rung number designating the program steps, but also allows the programs to be searched to be distributed in various places. Even though it is possible to search only at the same time by specifying only the rung number corresponding to the part, it is for easy error correction of program and insertion of necessary program.

Claims

When the rung number corresponding to the program step is input, the first program step S1 corresponding to the rung number R is designated and stored, and the first program step S2 corresponding to the rung number R + 1 is also stored. Storing the program step S1 corresponding to the rung number R in the screen information memory 12 and simultaneously displaying the same in the screen information memory 12; Increasing the memory pointer of the screen information memory 12 and storing the steps before the first program step of the next rung number R + 1 in the screen information memory 12 and displaying them on the monitor 11; When the other rung number is input again, PEL stores a program step corresponding to the screen information memory 12 until the screen information memory 12 is full and displays it on the monitor 11. Mr. Pro How to navigate the program of the ramming device.

The method according to claim 1, wherein when the load command is inputted, if the previous command is an output command, the current program step is stored in the rung information memory 17, and the rung number is increased to create a rung number. How to search program of Mr. programming device.

A keyboard 14 for inputting a command and a program required by a user, a program memory 13 for storing the program, a screen information memory 12 for storing information for external display among stored programs, and A rung number for designating a program step, a monitor 11 for displaying screen information, a central processing unit 15 for controlling the overall apparatus, an O / S ROM 16 for storing control commands thereof, and a program step. PLC programming device, characterized in that consisting of the rung information memory for storing the (17).
