3.主要抗干扰措施
（1）电源的合理处理，抑制电网引入的干扰
对于电源引入的电网干扰可以安装一台带屏蔽层的变比为1：1的隔离变压器，以减少设备与地之间的干扰，还可以在电源输入端串接LC滤波电路。
（4）正确选择接地点，完善接地系统
良好的接地是***PLC可靠工作的重要条件，可以避免偶然发生的电压冲击危害。接地的目的通常有两个，其一为了安全，其二是为了抑制干扰。完善的接地系统是PLC控制系统抗电磁干扰的重要措施之一。
PLC控制系统的地线包括系统地、屏蔽地、交流地和保护地等。接地系统混乱对PLC系统的干扰主要是各个接地点电位分布不均，不同接地点间存在地电位差，引起地环路电流，影响系统正常工作。例如电缆屏蔽层必须一点接地，如果电缆屏蔽层两端A、B都接地，就存在地电位差，有电流流过屏蔽层，当发生异常状态如雷击时，地线电流将更大。
