少有人走的路命名空间：netMarketing.automation.plc.softPlc
功能：三菱FX2N PLC仿真
功能详细说明：
目前暂时只支持三菱PLC fx2n的下列指令：
LD,LDI,LDP,LDF,AND,ANB,ANI,ANDP,ANDF,OR,ORI,ORB,ORP,ORF,OUT,MPS,MPP,MRD,INC,DEC,SET,RST,MOV,XCH,END
这个类是勇哥很早以前开发的，本意是想做一款plc学习软件，后来由于3D场景仿真困难比较大，这个项目就搁浅了。
后来发现这个类还有个意义是用来以PLC梯形图的方式调用封装好的C#的资源，即结合了PLC和C#各自的优点来开发上位机软件。
如果要实现这一点，需要开发梯形图编辑器，这个也是比较困难的事。勇哥在这方面暂时没有精力继续，期待有感兴趣的朋友可以深入研究下去，如果需要的话，勇哥可以提供源代码。
下面的程序是这个类的一个应用。
这个程序的梯型图编辑只是实现了基本的画元件，但是没能实现梯型图超过一屏后的滚动条卷动的处理过程。
另外，梯型图转指令或者指令转梯型图的功能也没能够完成。
下面的代码只是演示程序的主界面的代码，如果你有兴趣的话，完整的演示程序可以找勇哥索要。
