PLC系統接地要求比較嚴格，宜有獨立的專用接地系統，還要注意與PLC有關的其他設備也要可靠接地。多個電路接地點連接在一起時，會產生意想不到的電流，導致邏輯錯誤或損壞電路。產生不同的接地電勢的原因，通常是由于接地點在物理區域上被分隔的太遠，當相距很遠的設備被通信電纜或傳感器連接在一起的時候，電纜線和地之間的電流就會流經整個電路，即使在很短的距離內，大型設備的負載電流也可以在其與地電勢之間產生變化，或者通過電磁作用直接產生不可預知的電流。在不正確的接地點的電源之間，電路中有可能產生毀滅性的電流，以至于破壞設備。

PLC系統一般宜選用單點接地方式。為了提高抗共模干擾能力，對于模擬信號可以采用屏蔽浮地技術，即信號電纜的屏蔽層一點接地，信號回路浮空，與大地絕緣電阻應不小于50MΩ。
