描述

BENTLY-3500.20

在功能指令的学习中应特别关注一下PID、CJ、CALL等一些较难理解而又应用广泛指令的学习和掌握。针对这些指令在学习理论知识的同时，还要结合一些成熟的程序范例加以深度的理解和揣摩，在此基础上可以针对一些小型的生产任务加以编程练习，以练促学，边学边练。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。
最后，PLC提供了丰富的指令、模块，比单片机方便了很多。但是初学者编程时应尽量先使用简单的指令达到目的。尽管看上去有点土，却不失为一个入门的好途径，且对你理解那些较为复杂的指令会有帮助。具备了一定经验后，应该考虑掌握复杂指令的应用，以及程序的优化。

主营：本特利，英维思，伍德沃德，福克斯波罗、西屋、瑞恩、施耐德莫迪康、ABB、AB、西门子、摩托罗拉、GE发那科、安川、博世力士乐，ACSO，力士乐等各大品牌的DCS系统配件，机器人系统配件，大型伺服系统备件。

先介绍几点经验。
1、先通读一遍“系统手册”（不管能不能看懂，先了解个大概，以便学习编程时查找）；
2、由位控逻辑入手，逐渐增加定时、计数等条件，把或、与、非关系理顺；
3、进而练习整数运算、实数运算、类型转换；
4、量程转换、PID调节回路的建立及P、I、D参数的理解（最好是有个物理回路验证，比如变频器+电机+测速传感器）；
5、循环、顺序、跳转等程序控制（尽量避免跳转，非跳不可时也是跳的越近越好）；
6、中断、通讯、位置控制....

本人以ABB工业机器人配件DSQC系列和Motorola MVME系列，GE 卡件 模块 驱动器系列为主攻。各位电工朋友可根据自己的条件选择适合自己的PLC品牌，由于PLC的基本框架大同小异，学会一种至于其它的学习起来也就简单了。
