基于表格技术的软PLC梯形图编辑软件

A Soft PLC Ladder Diagram Edit Software Based on Table Technology

本文设计了一种能用于PLC梯形图编辑的表格类,并采用C++语言成功开发出了软件。该软件的优点在于梯形图器件单元所占表格大小可任意设定,器件数量没有限制,编辑界面可直接设置参数,能直观表达任意复杂的PLC梯形图应用。

This paper designs a table class which can be used to edit PLC ladder diagram, and successfully develops software using C＋＋ language. The main advantages of the software are as follows： the size of table cell occupied by the ladder diagram device unit can be set arbitrarily; the number of devices has no restriction; the parameters of PLC device unit can be directly set on ladder dia- gram; the software is intuitionistic in expressing application of complex PLC ladder diagram.
