基本文字符号、单字母符号和双字母符号表示电气设备、装置和元器件的大类，如K为继电器类元件这一大类；双字母符号由一个表示大类的单字母与另一表示器件某些特性的字母组成，例如表示继电器类元件中的KA为中间继电器。
为了确保整个系统能在状态下可靠工作，避免由于外部电源发生故障、PLC出现异常、误操作以及误输出造成的重大经济损失和人身伤亡事故，PLC外部应安装必要的保护电路。
②机床电气；
机器人控制器已经被用于实现某些复杂机械设备的控制。大多数控制器都是为某个特定的设备定制生产，需要使用厂家自有的专门编程语言进行编程，这些编程语言因产品平台的不同而有很大的差异。如果机器人控制器用于控制其为之定制的对象，效率很高，但是在通讯性能、集成性能以及可编程能力方面则不是的。
开关量输出模块的输出电流(驱动能力)必须大于PLC外接输出设备的额定电流。用户应根据实际输出设备的电流大小来选择输出模块的输出电流。如果实际输出设备的电流较大，输出模块无法直接驱动，可增加中间放大环节。
