PLC也是基于計(jì)算機(jī)的技術(shù)，并日益完善。故它也*可以用于數(shù)字量控制。
PLC可接收計(jì)數(shù)脈沖，頻率可高達(dá)幾k到幾十k赫茲。可用多種方式接收這脈沖，還可多路接收。有的PLC還有脈沖輸出功能，脈沖頻率也可達(dá)幾十k。有了這兩種功能，加上PLC有數(shù)據(jù)處理及運(yùn)算能力，若再配備相應(yīng)的傳感器（如旋轉(zhuǎn)編碼器）或脈沖伺服裝置（如環(huán)形分配器、功放、步進(jìn)電機(jī)），則*可以依NC的原理實(shí)現(xiàn)種種控制。
高、中檔的PLC，還開發(fā)有NC單元，或運(yùn)動單元，可實(shí)現(xiàn)點(diǎn)位控制。運(yùn)動單元還可實(shí)現(xiàn)曲線插補(bǔ)，可控制曲線運(yùn)動。所以，若PLC配置了這種單元，則*可以用NC的辦法，進(jìn)行數(shù)字量的控制。
