编码器是一种光电式旋转测量装置，它将被测的角位移直接转换成数字信号（高速脉冲信号）。因此可将编码器的输出脉冲信号直接输入给plc，利用PLC的高速计数器对其脉冲信号进行计数，欧姆龙触摸屏，以获得测量结果。
不同型号的编码器，其输出脉冲的相数也不同，有的编码器输出A、B、Z三相脉冲，有的只有A、B相两相，zui简单的只有A相。

如图所示是输出两相脉冲的编码器与FX2N系列PLC的连接示意图。
编码器有4条引线，其中2条是脉冲输出线，1条是COM端线，1条是电源线。
编码器的电源可以是外接电源，也可直接使用PLC的DC24V电源。电源“-”端要与编码器的COM端连接，“+ ”与编码器的电源端连接。
编码器的COM端与PLC输入COM端连接，A、B两相脉冲输出线直接与PLC的输入端连接，连接时要注意PLC输入的响应时间。有的旋转编码器还有一条屏蔽线，使用时要将屏蔽线接地。
