描述

此外，屏蔽层、接地线和大地可能构成闭合环路，在变化磁场的作用下，屏蔽层内会出现感应电流，通过屏蔽层与芯线之间的耦合，干扰信号回路。若系统地与其它接地处理混乱，所产生的地环流就可能在地线上产生不等电位分布，影响PLC内逻辑电路和模拟电路的正常工作。PLC工作的逻辑电压干扰容限较低，逻辑地电位的分布干扰容易影响PLC的逻辑运算和数据存贮，造成数据混乱、程序跑飞或死机。模拟地电位的分布将导致测量精度下降，引起对信号测控的严重失真和误动作。

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，如逻辑电路相互辐射、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。这都属于PLC制造厂家对系统内部进行电磁兼容设计的内容，比较复杂，作为应用部门无法改变，可不必过多考虑，但要选择具有较多应用实绩或经过考验的系统。
