控制速度——繼電器控制邏輯依靠觸點(diǎn)的機(jī)械動(dòng)作實(shí)現(xiàn)控制，工作頻率低，且機(jī)械觸點(diǎn)還會(huì)出現(xiàn)抖動(dòng)問(wèn)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，屬于無(wú)觸點(diǎn)控制，速度極快，且不會(huì)出現(xiàn)抖動(dòng)。
（5）定時(shí)控制——繼電器控制邏輯利用時(shí)間繼電器進(jìn)行時(shí)間控制。時(shí)間繼電器存在定時(shí)精度不高，定時(shí)范圍窄，且易受環(huán)境濕度和溫度變化的影響，調(diào)整時(shí)間困難等問(wèn)題。PLC使用半導(dǎo)體集成電路做定時(shí)器時(shí)基脈沖由晶振產(chǎn)生，精度相當(dāng)高，且定時(shí)時(shí)間不受環(huán)境的影響，定時(shí)范圍廣，調(diào)整時(shí)間方便。（6）設(shè)計(jì)和施工——使用繼電器控制邏輯完成一項(xiàng)工程，其設(shè)計(jì)、施工、調(diào)試必須依次進(jìn)行，周期長(zhǎng)、而且修改困難。而用PLC完成一項(xiàng)控制工程，在系統(tǒng)設(shè)計(jì)完成后，現(xiàn)場(chǎng)施工和控制邏輯的設(shè)計(jì)可以同時(shí)進(jìn)行，周期短，且調(diào)試和修改都很方便。
