PLC自身故障判断
    一般来说，PLC是极其可靠的设备，出故障率很低。PLC的CPU等硬件损坏或软件运行出错的概率几乎为零；PLC输入点如不是强电入侵所致，几乎也不会损坏；PLC输出继电器的常开点，若不是外围负载短路或设计不合理，负载电流超出额定范围，触点的寿命也很长。
    因此，我们查找电气故障点，重点要放在PLC的外围电气元件上，不要总是怀疑PLC硬件或程序有问题，这对快速维修好故障设备、快速恢复生产是十分重要的，因此笔者所谈的PLC控制回路的电气故障检修，重点不在PLC本身，而是PLC所控制回路中的外围电气元件。
输入输出（I/O）模块的选取
    输出模块分为晶体管、双向可控硅、接点型。
    晶体管型的开关速度最快（一般0.2ms），但负载能力最小，约0.2~0.3A、24VDC，适用于快速开关、信号联系的设备，一般与变频、直流装置等信号连接，应注意晶体管漏电流对负载的影响。
    可控硅型优点是无触点、具有交流负载特性，负载能力不大。
    继电器输出具有交直流负载特点，负载能力大。常规控制中一般首先选用继电器触点型输出，缺点是开关速度慢，一般在10ms左右，不适于高频开关应用。

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。
