（1）强电干扰：PLC系统的正常供电电源均由电网供电。由于电网覆盖范围广，它将受到所有空间电磁干扰而在线路上感应电压。尤其是电网内部的变化， 如刀开关的使用均会产生电网内部的扰动。
刀开关也就是我们通常所说的闸刀开关，是一种接通和分断交直流电路或作隔离开关用的手动开关装置。操作浪涌、大型电力设备起停、交直流传动装置引起的谐波、电网短路暂态冲击等，都通过输电线路传到电源原边。
（2）柜内干扰：控制柜内的高压电器，大的电感性负载，混乱的布线都容易对PLC造成一定程度的干扰。
来自信号线引入的干扰：与PLC控制系统连接的各类信号传输线，除了传输有效的各类信息之外，总会有外部干扰信号侵入。
此干扰主要有两种途径：一是通过变送器
变送器是将物理测量信号或普通电信号转换为标准电信号输出或能够以通讯协议方式输出的设备。供电电源或共用信号仪表的供电电源串入的电网干扰,这往往被忽视；
二是信号线受空间电磁辐射感应的干扰，即信号线上的外部感应干扰，这是很严重的。由信号引入干扰会引起I／O信号工作异常和测量精度大大降低，严重时将引起元器件损伤。
（3）来自接地系统混乱时的干扰：接地是提高电子设备电磁兼容性(EMC)的有效手段之一。正确的接地，既能抑制电磁干扰的影响，又能抑制设备向外发出干扰；而错误的接地，反而会引入严重的干扰信号，使PLC系统将无法正常工作。
（4）来自PLC系统内部的干扰：主要由系统内部元器件及电路间的相互电磁辐射产生，如逻辑电路
逻辑电路是包含逻辑关系的数字电路， 以二进制为原理、实现数字离散信号的传递，逻辑运算和操作的电路。**基本的逻辑电路是常见的门电路，而**简单的门电路为与电路、或电路和非电路。相互辐射及其对模拟电路的影响，模拟地与逻辑地的相互影响及元器件间的相互不匹配使用等。
（5）变频器干扰：一是变频器启动及运行过程中产生谐波对电网产生传导干扰，引起电网电压畸变，影响电网的供电质量；二是变频器的输出会产生较强的电磁辐射干扰，影响周边设备的正常工作。
