（6）液位传感器——输入信号反映液压油箱、润滑液箱、冷却液箱、回流液箱内液面的高低。
尚有另外一些输入信号，借助予一些按钮和开关送到PLC中从略。
PLC 的输出信号比较简单。PLC的24VDC电源输出与各继电器线圈、电磁阀线圈或指示灯等元件相连，或驱动某元件动作，或发出某信号。电气原理图中对PLC 输出信号的注释往往有很明确的含义，维修人员不会误解。例如，某输出信号A××.×的注释是：“夹紧工作台”，则我们可以立即知道：当输出信号A××.× ＝“1”（逻辑“1”，即24VDC）时，就会发生夹紧工作台的动作。把A××.×＝“1”跟注释内容对应起来，划***号。
然而，对于PLC的输入信号，情况则不然，因为E××.×＝“1”跟注释内容并不一定能对等起来。我们把输入信号＝“1”与注释内容相对应称为“正逻辑”注释法；把输入信号＝“0”与注释内容相对应称为“负逻辑”注释法。例如，我公司CW800加工中心上用E8.7＝“1”表示“液压油温度太高”，使用了 “正逻辑”的注释法，而另一台CW500加工中心，虽出自同一制造厂，却以E23.1＝“0”表示“液压油温度太高”，使用了“负逻辑”注释法。
一台机床的PLC输入信号注释如果全部使用“正逻辑”，会给故障诊断带来很大的方便；
