【摘要】 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。更多还原

【Abstract】 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 diagram;the software is intuitionistic in expressing application of complex PLC ladder diagram.更多还原
