系統(tǒng)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控制系統(tǒng)而言，它屬高速低電平控制裝置，應(yīng)采用直接接地方式。由于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于1MHz，所以PLC控制系統(tǒng)接地線采用一點接地和串聯(lián)一點接地方式。集中布置的PLC系統(tǒng)適于并聯(lián)一點接地方式，各裝置的柜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(yīng)采用串聯(lián)一點接地方式。用一根大截面銅母線（或絕緣電纜）連接各裝置的柜體中心接地點，然后將接地母線直接連接接地極。接地線采用截面大于22 mm2的銅導(dǎo)線，總母線使用截面大于60mm2的銅排。接地極的接地電阻小于2Ω，接地極埋在距建筑物10 ~ 15m遠處(或與控制器間不大于50m)，而且PLC系統(tǒng)接地點必須與強電設(shè)備接地點相距10m以上。
