A Ladder Diagram Online Editing Method

Abstract

The present invention provides a ladder diagram online editing system and a ladder diagram online editing method. The ladder diagram online editing system comprises a code realization module and an interface operation module, and the interface operation module comprises a ladder diagram matrix editing module of inserting a new ladder diagram at the specific position of a conventional ladder diagram; a ladder diagram matrix management module of loading a CSV file or the ladder diagram matrix editing module to re-edit to obtain a current ladder diagram matrix, saving and then enabling globally; and a file management module for loading, saving and refreshing the CSV file. The code realization module supports the ladder diagram matrix editing module, and calculates and outputs the results according to the input. On the basis of aiming at a type of mature scheme, the ladder diagram online editing system and the ladder diagram online editing method of the present invention allow the users to carry out some simple and self-defined modification, and give the corresponding logic, thereby saving the secondary development time and cost.

Description

technical field [0001] The invention relates to a system for online editing of ladder diagrams, and also relates to a method for online editing of ladder diagrams, belonging to the field of industrial control. Background technique [0002] When using PLC for industrial control, generally speaking, the program needs to be compiled by the development software before being recognized and run by the PLC. The development software is independent of the touch screen of the machine, and it is impossible to write a ladder diagram program online and integrate it with the existing one. The input and output are associated. If the on-site machine needs to make some simple hardware or logic changes, it still needs to be modified through the development software and the program is burned into the PLC again. On-site operators often do not have this ability, and developers need to go to the site to modify the program and send it to the PLC. This process generates higher costs. Contents of...
