工作方式：當(dāng)電流接通時(shí)，繼電控制線路中各繼電器都處于受約狀態(tài)，即該吸合的都應(yīng)吸合，不該吸合的都因受某種條件限制不能吸合。而PLC的控制邏輯中，各繼電器都處于周期性循環(huán)掃描接通之中，從宏觀上看，每個(gè)繼電器受制約接通的時(shí)間是短暫的。
控制速度：繼電控制邏輯依靠觸點(diǎn)的機(jī)械動(dòng)作實(shí)現(xiàn)控制，工作頻率低。觸點(diǎn)的開閉動(dòng)作一般在幾十毫秒數(shù)量級(jí)。另外機(jī)械觸點(diǎn)還會(huì)出現(xiàn)抖動(dòng)問題。而PLC是由程序指令控制半導(dǎo)體電路來(lái)實(shí)現(xiàn)控制的，速度極快，一般一條用戶指令的執(zhí)行時(shí)間在微秒數(shù)量級(jí)。PLC內(nèi)部還有嚴(yán)格的同步，不會(huì)出現(xiàn)抖動(dòng)問題
限時(shí)控制：繼電控制邏輯利用時(shí)間繼電器的滯后動(dòng)作進(jìn)行限時(shí)控制。時(shí)間繼電器一般分為空氣阻尼式、電磁式、半導(dǎo)體式等，其定時(shí)精度不高，定時(shí)時(shí)間易受環(huán)境濕度和溫度變化的影響，調(diào)整時(shí)間困難。有些特殊的時(shí)間繼電器結(jié)構(gòu)復(fù)雜，不便維護(hù)。 PLC使用半導(dǎo)體集成電路作定時(shí)器，時(shí)基脈沖由晶體振蕩器產(chǎn)生，精度相當(dāng)高，定時(shí)范圍一般從0.1 s到若干分鐘甚至更長(zhǎng)，用戶可根據(jù)需要在程序中設(shè)定定時(shí)值，然后由軟件和硬件計(jì)數(shù)器來(lái)控制定時(shí)時(shí)間，定時(shí)精度小于10 ms且定時(shí)時(shí)間不受環(huán)境的影響。
