影响PLC控制系统的干扰源与一般影响工业控制设备的干扰源一样，大都
产生在电流或电压剧烈变化的部位，这些电荷剧烈移动的部位就是噪声源，
即干扰源。
干扰类型通常按干扰产生的原因、噪声干扰模式和噪声的波形性质的
不同划分。其中：按噪声产生的原因不同，分为放电噪声、浪涌噪声、高
频振荡噪声等；按噪声的波形、性质不同，分为持续噪声、偶发噪声等；
按噪声干扰模式不同，分为共模干扰和差模干扰。共模干扰和差模干扰是
一种比较常用的分类方法。共模干扰是信号对地的电位差，主要由电网串
入、地电位差及空间电磁辐射在信号线上感应的共态（同方向）电压迭加
所形成。共模电压有时较大，特别是采用隔离性能差的配电器供电室，变
送器输出信号的共模电压普遍较高，有的可高达130V以上。共模电压通过
不对称电路可转换成差模电压，直接影响测控信号，造成元器件损坏（这
就是一些系统I/O模件损坏率较高的主要原因），这种共模干扰可为直流、
亦可为交流。差模干扰是指作用于信号两极间的干扰电压，主要由空间电
磁场在信号间耦合感应及由不平衡电路转换共模干扰所形成的电压，这种
让直接叠加在信号上，直接影响测量与控制精度。
