實(shí)際的物理量，除了開關(guān)量、模擬量，還有運(yùn)動控制。如機(jī)床部件的位移，常以數(shù)字量表示。
PLC也是基于計(jì)算機(jī)的技術(shù)，并日益完善。故它也完全可以用于數(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?？捎枚喾N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)），則完全可以依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，則完全可以用NC的辦法，進(jìn)行數(shù)字量的控制。
用于數(shù)據(jù)采集
隨著PLC技術(shù)的發(fā)展，其數(shù)據(jù)存儲區(qū)越來越大。如德維森公司的PLC，其數(shù)據(jù)存儲區(qū)（DM區(qū)）可達(dá)到9999個字。這樣龐大的數(shù)據(jù)存儲區(qū)，可以存儲大量數(shù)據(jù)。
數(shù)據(jù)采集可以用計(jì)數(shù)器，累計(jì)記錄采集到的脈沖數(shù)，并定時地轉(zhuǎn)存到DM區(qū)中去。
數(shù)據(jù)采集也可用A／D單元，當(dāng)模擬量轉(zhuǎn)換成數(shù)字量后，再定時地轉(zhuǎn)存到DM區(qū)中去。
PLC也可與計(jì)算機(jī)通訊，由計(jì)算機(jī)把DM區(qū)的數(shù)據(jù)讀出，并由計(jì)算機(jī)再對這些數(shù)據(jù)作處理。這時，PLC即成為計(jì)算機(jī)的數(shù)據(jù)終端。
電力用戶曾使用PLC，用以實(shí)時記錄用戶用電情況，以實(shí)現(xiàn)不同用電時間、不同計(jì)價的收費(fèi)辦法，鼓勵用戶在用電低谷時多用電，達(dá)到合理用電與節(jié)約用電的目的。
用于信號監(jiān)控
PLC自檢信號很多，內(nèi)部器件也很多，多數(shù)使用者未充分發(fā)揮其作用。
其實(shí)，完全可利用它進(jìn)行PLC自身工作的監(jiān)控，或?qū)刂茖ο筮M(jìn)行監(jiān)控。
對一個復(fù)雜的控制系統(tǒng)，特別是自動控制系統(tǒng)，監(jiān)控以至進(jìn)一步能自診斷是非常必要的。它可減少系統(tǒng)的故障，出了故障也好查找，可提高累計(jì)平均無故障運(yùn)行時間，降低故障修復(fù)時間，提高系統(tǒng)的可靠性。
