實際的物理量，除了開關(guān)量、模擬量，還有運動控制。如機(jī)床部件的位移，常以數(shù)字量表示。

運動控制，有效的辦法是NC，即數(shù)字控制技術(shù)。這是50年代誕生于美的基于計算機(jī)的控制技術(shù)。當(dāng)今已很普及，并也很完善。目前，先進(jìn)的金屬切削機(jī)床，數(shù)控化的比率已超過40％～80％，有的甚至更高。
PLC也是基于計算機(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的原理實現(xiàn)種種控制。
