PLC操控體係信號電纜的挑選與敷設應嚴厲依照有關規則履行。屏蔽電纜的屏蔽層應按以上請求進行接地。為了行進PLC操控體係的抗攪擾才幹，PLC操控體係開關量輸入／輸出信號宜選用阻燃型對絞銅網屏蔽電纜。
依據多個工程現場實踐的經歷，提出以下PLC操控體係接地的留意事項。
操作員站、工程師站、網絡交換機、效勞器主機、體係顯現器等應選用外殼接地或直接將電源地線銜接至電氣接地網。
PLC操控體係I/O機櫃的電源接地與UPS的電源接地有必要銜接至同一個地，以確保等電位。
PLC操控體係模倣量I/O模塊的信號負端，即直流24V電源的負端銜接至邏輯接地排上，邏輯接地排與屏蔽接地相銜接，終究接入總接地排。這麼可以有用共模電壓的攪擾。
