DCS接地是一個很復雜的問題，涉及到接地地點，接地方式，接地電阻大小等從現(xiàn)場到DCS機柜的諸多節(jié)點和環(huán)節(jié)。但日常對DCS的常規(guī)檢查主要有幾個方面：
1、DCS機柜應采用單點接地方式，檢查是否有可能導致多點接地的地方出現(xiàn)，比如機柜與槽鋼的接觸，接地點是否為單條引下線（線徑大于16mm2，長度小于30米）到地樁或地網(wǎng)，部件連接（或焊接）點是否良好（銹蝕）等。
2、檢查DCS接地點與電氣地或避雷針引下線接地是否共用，距離是否符合要求，一般情況要求DCS接地與電氣地距離15米以上，與避雷針接地點15米以上。
3、測量DCS系統(tǒng)接地電阻是否小于
4、很多因素相關，如接觸良好，土壤濕度，導電率等，測量接地電阻可選用的儀器有搖表、鉗形表等。
