4、正确选择接地点，完善接地系统
接地的目的通常有两个，其一为了安全，其二是为了干扰。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。
系统接地方式有：浮地方式、直接接地方式和电容接地三种方式。对PLC控制系统而言，它属高速低电平控制装置，应采用直接接地方式。由于信号电缆分布电容和输入装置滤波等的影响，装置之间的信号交换频率一般都低于1MHz，所以PLC控制系统接地线采用一点接地和串联一点接地方式。集中布置的PLC系统适于并联一点接地方式，各装置的柜体中心接地点以单独的接地线引向接地较。如果装置间距较大，应采用串联一点接地方式。用一根大截面铜母线（或绝缘电缆）连接各装置的柜体中心接地点，然后将接地母线直接连接接地较。接地线采用截面大于22 mm2的铜导线，总母线使用截面大于60mm2的铜排。接地较的接地电阻小于2Ω，接地较埋在距建筑物10 ~ 15m远处(或与控制器间不大于50m)，而且PLC系统接地点必须与强电设备接地点相距10m以上。
信号源接地时，层应在信号侧接地；不接地时，应在PLC侧接地；信号线中间有接头时，层应牢固连接并进行绝缘处理，一定要避免多点接地；多个测点信号的双绞线与多芯对绞总屏电缆连接时，各层应相互连接好，并经绝缘处理。选择适当的接地处单点接点。
