的PLC老师应当是收集大量程序供学生编程训练参考。编好程序开始不是闭门造车。按书上的例程自己在PLC上编写一遍，用PLC实验一遍。有些好的程序示例一定要记下来。如果把学习PLC比作习武的话这些程序示例就是招式，习武在初期只有一招一式的学好基础才能有朝一日一鸣惊人。而PLC编程就是一招千式；学好这些示例（招式）后才能综合应用。如果你自己有能力按照以上的方法完成，一定会学有所成、学有所用。还是一名老话，没有时间与毅力，一定会前功尽弃。

地址的规划和选择首先要根据需要、功能来决定，然后在plc编程中所表达的动作进行统一编号，对于PLC的顺控程序，我们尽量在编程时进行段的声明、注释准确如下图，把整个PLC程序分成好几个小段写，每个小段可以写特定的动作组合、部分、功能、意义等，然后地址的规划在每段进行排列，第一段用M0~M100，第二段用M100~M200等等设计，方便我们寻找元件变量，对编程和后期的调试都很有帮助。还有就是为了便于记忆，我们也可以采用标签对软件变量进行标记，免去注释，比如X0的标签是开始，Y0的标签是指示灯，以后我们就可以直接用“LD原点OUT指示灯”来表示LDX0OUTY0了，这样就更方便了，PLC中每个变量都可以做标签进行声明。
