本三菱 PLC梯型图（指令编码）反汇编程序是 三菱 PLC梯型图 转 HEX 文件的重要组成部分，由于考虑到今后程序移植的方便，未使用控件，仅用最基本的 C 语言语句编写。 
    本程序的 三菱 PLC梯型图 测试程序 PLC2N.PMW 由 ourDEV 网友 easygoing 编写，再次表示感谢其对开源 PLC 的支持， 在本例中转换成同名的 PLC2N.C 程序。再经 Keil C 编译成 HEX 文件执行。
    本“三菱 PLC梯型图（指令编码）反汇编程序”将和“PLC梯型图（指令编码）转 51 C语言”组合，由网友 xingliu 编写操作界面软件，使之更适合广大片机爱好者使用。         
    由于作者水平有限，未正规学过 C 语言，失误和错误难免，请广大网友指正，拍砖。
