大量現(xiàn)貨abb,施耐德等國(guó)外多家品牌，產(chǎn)品涉及變頻器，儀器儀表，變送器，可編程控制器plc和人機(jī)界面。

　　實(shí)際的物理量，除了開(kāi)關(guān)量、模擬量，還有運(yùn)動(dòng)控制。如機(jī)床部件的位移，常以數(shù)字量表示。運(yùn)動(dòng)控制，有效的辦法是NC，即數(shù)字控制技術(shù)。這是50年代誕生于美國(guó)的基于計(jì)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)國(guó)家的金屬切削機(jī)床，數(shù)控化的比率已超過(guò)40%～80%，有的甚至更高。PLC也是基于計(jì)算機(jī)的技術(shù)，并日益完善。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，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(kāi)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，則完全可以用NC的辦法，進(jìn)行數(shù)字量的控制。新開(kāi)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。
