實際的物理量，除了開關量、模擬量，還有運動控制。如機床部件的位移，常以數字量表示。
運動控制，有效的辦法是NC，即數字控制技術。這是50年代誕生于美國的基于計算機的控制技術。當今已很普及，并也很完善。目前，先進國家的金屬切削機床，數控化的比率已超過40％～80％，有的甚至更高。
PLC也是基于計算機的技術，并日益完善。故它也完全可以用于數字量控制。
PLC可接收計數脈沖，頻率可高達幾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，脈沖頻率也可達幾十k。有了這兩種功能，加上PLC有數據處理及運算能力，若再配備相應的傳感器（如旋轉編碼器）或脈沖伺服裝置（如環形分配器、功放、步進電機），則完全可以依NC的原理實現種種控制。
