4、正確選擇接地點，完善接地係統

接地的目的通常有兩個，其一為了，其二是為了抑制幹擾。完善的接地係統是PLC控制係統抗電磁幹擾的重要措施之一。

係統接地方式有：浮地方式、直接接地方式和電容接地三種方式。對PLC控制係統而言，它屬高速低電平控制裝置，應採用直接接地方式。由於信號電纜分布電容和輸入裝置濾波等的影響，裝置之間的信號交換頻率一般都低於1MHz，所以PLC控制係統接地線採用一點接地和串聯一點接地方式。

----------------------------------------------

集中布置的PLC係統適於並聯一點接地方式，各裝置的櫃體中心接地點以單獨的接地線引向接地極。如果裝置間距較大，應採用串聯一點接地方式。用一根大截面銅母線（或絕緣電纜）連接各裝置的櫃體中心接地點，然後將接地母線直接連接接地極。接地線採用截面大於22 mm2的銅導線，總母線使用截面大於60mm2的銅排。接地極的接地電阻小於2Ω，接地埋在距建築物10 ~ 15m遠處(或與控制器間不大於50m)，而且PLC係統接地點與強電設備接地點相距10m以上。

信號源接地時，屏蔽層應在信號側接地；不接地時，應在PLC側接地；信號線中間有接頭時，屏蔽層應牢固連接並進行絕緣處理，要避免多點接地；多個測點信號的屏蔽雙絞線與多芯對絞總屏電纜連接時，各屏蔽層應相互連接好，並經絕緣處理。選擇適當的接地處單點接點。
