成功就是簡單的事情重復的去做．之所以有人不成功，并非是他做不到，而
是他不愿意做這些簡單而重復的事．
而且，
越簡單越容易的事情，
人們越不容易
去做它．
編碼器是一種光電式旋轉測量裝置，它將被測的角位移直接轉換成數(shù)字信號（高速脈沖信號）。因此可將編碼器的輸出脈沖信號直接輸入給plc，利用PLC的高速計數(shù)器對其脈沖信號進行計數(shù)，歐姆龍觸摸屏，以獲得測量結果。
不同型號的編碼器，其輸出脈沖的相數(shù)也不同，有的編碼器輸出A、B、Z三相脈沖，有的只有A、B相兩相，zui簡單的只有A相。

如圖所示是輸出兩相脈沖的編碼器與FX2N系列PLC的連接示意圖。
編碼器有4條引線，其中2條是脈沖輸出線，1條是COM端線，1條是電源線。
編碼器的電源可以是外接電源，也可直接使用PLC的DC24V電源。電源“-”端要與編碼器的COM端連接，“+ ”與編碼器的電源端連接。
編碼器的COM端與PLC輸入COM端連接，A、B兩相脈沖輸出線直接與PLC的輸入端連接，連接時要注意PLC輸入的響應時間。有的旋轉編碼器還有一條屏蔽線，使用時要將屏蔽線接地。
