1） PLC的良好接地是正常運(yùn)行的前提。在設(shè)計(jì)時(shí)，PLC的接地應(yīng)與動(dòng)力設(shè)備的接地分開(kāi)，采用專(zhuān)用接地；如不能分開(kāi)接地時(shí)，應(yīng)采用共用接地；禁止采用共通接地方法。
2） PLC的接線(xiàn)包括輸入接線(xiàn)和輸出接線(xiàn)。輸入接線(xiàn)的長(zhǎng)度不宜過(guò)長(zhǎng)，一般不大于30m；在線(xiàn)路距離較長(zhǎng)時(shí)，可采用中間繼電器進(jìn)行信號(hào)的轉(zhuǎn)換。輸入接線(xiàn)的COM端與輸出接線(xiàn)的COM端不能接在一起。輸入接線(xiàn)與輸出接線(xiàn)的電纜應(yīng)分開(kāi)設(shè)置。必要時(shí)，可在現(xiàn)場(chǎng)分別設(shè)置接線(xiàn)箱。集成電路或晶體管設(shè)備的輸入信號(hào)和輸出信號(hào)的接線(xiàn)必須采用屏蔽電纜；屏蔽層的接地端應(yīng)為一點(diǎn)接地，接地點(diǎn)宜在控制器側(cè)。
