编程需要敢于实践的信心
我曾经教过一个学生学AutoCAD，我对她的*要求就是实践。我告诉她：你随便怎么操作，大不了一张图重画；zui坏的结果是系统崩溃，没关系，系统重做，再来；只要电脑没被砸了，怎么都行。两年后，我再看到她做的CAD图纸，也自叹不如。
同样道理，只有不断地在PLC上运行这些指令，观察运行的结果，才能弄清PLC指令的作用。很多初学者对PLC一脸的迷茫，往往是出于一种畏惧，担心损坏设备。而这些畏惧是没有任何道理的。仔细的阅读手册是非常重要的，但是仅靠读书是成不了一个工程师的。更何况手册上的内容并非面面俱到。我在接触到那些不熟悉的指令时，喜欢单独编一个小程序，让PLC运行。然后逐个修改条件，观察运行的结果（MicroWin为用户提供了非常好的监控手段），反过来再重新理解手册的描述，这样就可以非常直观的理解这些指令的作用和使用方法。

不必担心自己写的程序会有什么问题，会影响PLC的正常工作。程序有没有问题，只有让PLC运行了才能发现。而发现问题并解决问题就是对自己能力的提高。撇开硬件操作不谈，单就软件来说，我还真没有遇到过由于软件问题而损坏PLC的事。在这里不必担心继电器电路接错线可能造成的后果。所以，大胆的实践是PLC编程的必由之路。
当然，大胆实践并不是野蛮操作，而是必须遵循必要的规范。还有一个要注意的，在程序未经可靠性证实之前，千万不要挂接负载，以免造成不必要的损失。数字量的输出有LED显示；而模拟量处理可以采用一些硬件或软件模拟手段来解决。
