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(dòng)單元，可實(shí)現(xiàn)點(diǎn)位控制。運(yùn)動(dòng)單元還可實(shí)現(xiàn)曲線插補(bǔ)，可控制曲線運(yùn)動(dòng)。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。
新開發(fā)的運(yùn)動(dòng)單元，甚至還發(fā)行了NC技術(shù)的編程語(yǔ)言，為更好地用PLC進(jìn)行數(shù)字控制提供了方便。
3.4用于數(shù)據(jù)采集
隨著PLC技術(shù)的發(fā)展，其數(shù)據(jù)存儲(chǔ)區(qū)越來(lái)越大。如德維森公司的PLC，其數(shù)據(jù)存儲(chǔ)區(qū)（DM區(qū)）可達(dá)到9999個(gè)字。這樣龐大的數(shù)據(jù)存儲(chǔ)區(qū)，可以存儲(chǔ)大量數(shù)據(jù)。
