可编程控制器、HMI人机界面的电磁干扰的主要来源和途径
1、来自空间的辐射对可编程控制器、HMI人机界面的干扰。
　　空间辐射电磁场主要来自现场动力线路、电气设备的暂态过程、雷电、无线信号、高频感应加热设备等，与现场设备布置及设备所产生的电磁场有关。可编程控制器、HMI受到的辐射干扰，主要通过两条路径：一是对通信网络的辐射，由通信线路感应引入干扰；二是直接对可编程控制器、HMI内部的辐射，由电路感应产生干扰。

2、来自电源的传导对PLC控制器的干扰
PLC控制器电源通常采用隔离电源，但因其机构及制造工艺等因素使其隔离性并不理想。实践中，因电源引入的干扰造成PLC控制器故障的情况很多。
PLC控制器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和电流，尤其是电网内部的变化、大型设备起停、开关操作浪涌、短路电流冲击、交直流传动装置引起的谐波等，都通过输电线路传到电源原边，产生干扰。主要通过两条路径：一是通过PLC控制器供电电源引入的干扰；二是通过变送器电源或共用信号仪表的供电电源引入的干扰。

3、来自信号线引入的传导对可编程控制器的干扰
　  与可编程控制器连接的各类信号传输线，除了传输有效的各类信号之外，还会受到外部干扰信号侵入。由信号引入的干扰会引起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。干扰主要有两种途径：一是通过变送器供电电源或共用信号仪表的供电电源串入的电网干扰；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。对于隔离、屏蔽性能差的系统，还将导致信号间互相干扰，引起共地系统总线回流，严重时造成系统误动和死机。
