PLC输入与输出
一只小小的PLC灵活地控制着一个复杂系统，所能看到的是上下两排错开的输入输出继电器接线端子、对应的指示灯及PLC编号，就像一块有数十只脚的集成电路。任何一个人如果不看原理图来检修故障设备，会束手无策，查找故障的速度会特别慢。鉴于这种情况，我们根据电气原理图绘制一张表格，贴在设备的控制台或控制柜上，标明每个PLC输入输出端子编号与之相对应的电器符号，中文名称，即类似集成电路各管脚的功能说明。有了这张输入输出表格，对于了解操作过程或熟悉本设备梯形图的电工就可以展开检修了。但对于那些对操作过程不熟悉，不会看梯形图的电工来说，就需要再绘制一张表格：PLC输入输出逻辑功能表。该表实际说明了大部分操作过程中输入回路(触发元件、关联元件)和输出回路(执行元件)的逻辑对应关系。实践证明如果你能熟练利用输入输出对应表及输入输出逻辑功能表，检修电气故障，不带图纸，也能轻松自如。
