摘 要

由于可編程控制器（PLC）是專為在工業(yè)環(huán)境下應(yīng)用而設(shè)計(jì)的一種工業(yè)控制計(jì)算機(jī)，具有抗干擾能力強(qiáng)、可靠性極高、體積小、是實(shí)現(xiàn)機(jī)電一體化的理想控制裝置等顯著優(yōu)點(diǎn)，因此通過實(shí)踐與深入研究，本文提出了利用西門子S7-200PLC改造數(shù)控機(jī)床的有關(guān)見解與方法，詳細(xì)介紹了控制系統(tǒng)研制中需要認(rèn)識與解決的若干問題，給出了控制系統(tǒng)方案及軟硬件結(jié)構(gòu)的設(shè)計(jì)思路，對于工礦企業(yè)實(shí)現(xiàn)相關(guān)機(jī)床改造具有較高的應(yīng)用與參考價(jià)值。

Abstract

Because the programmable controller (PLC) is specially for one industrial control computer which applies under the industry environment designs, has the antijamming ability to be strong, the reliability is high, the volume slightly, is extremely realizes the integration of machinery ideal control device and so on remarkable merit, therefore through the practice and the deep research, this article proposed uses Simens the S7-200PLC transformation numerically-controlled machine tool's related opinion and the method, introduced in detail in the control system development needs to know certain questions which and to solve, has given the control system plan and the software and hardware structure design mentality, realizes the related engine bed transformation regarding the Industrial and mining establishment to have the high application and the reference value.
