可编程逻辑控制器编辑软件的研究及实现

针对目前可编辑软件的缺陷和不足,基于面向对象的设计思想,开发了一套全新的可编程逻辑控制器编辑软件在梯形图编辑完成后,可以将梯形图转换成指令程序,通过指令解释器对指令表的解释得出程序的逻辑,可以实现程序的模仿真.开发出来的编辑软件作为一个编写可编程逻辑控制器程序的通用开发平台,功能强大、操作简单,本文具体着重介绍了编辑软件系统总体结构和编译器的设计.

Study and Realization of Editing Software for Programmable Logic Controller

Aiming at the limitation and lack of the current editing software for PLC basing on the idea of oriented- object ,a kind of completely new optimal software is developed . After the edit of ladder diagram is accomplished, it can be transformed to the instruction table, then the logic of procedure will be educed through the explanation of the instruction table from interpreter, and the imitating simulation of procedure can be realized. The software using this algorithm is not only powerful, but also simple to operate and convenient to use.
