【正文】 輸入和輸出在存儲(chǔ)器中都有一個(gè)相應(yīng)的位。在應(yīng)用程序開發(fā)中，通過一個(gè)串行電纜可以對(duì)程序存儲(chǔ)器進(jìn)行重新編程。除了這個(gè)操作系統(tǒng)之外，它還包括一個(gè)由梯形圖翻譯成而進(jìn)制形式的用戶程序。運(yùn)算器用于進(jìn)行數(shù)字或邏輯運(yùn)算，在控制器指揮下工作。模塊式 PLC 包括 CPU 模塊、 I/O 模塊、內(nèi)存、電源模塊、底板或機(jī)架，這些模塊可以按照一定規(guī)則組合配置。自動(dòng)售貨機(jī)行業(yè)長期以來在美國、日本等國家得到迅猛發(fā)展，目前已在多個(gè)國家得到廣泛普及。 可編程序控制器 ( PLC)是綜合了計(jì)算機(jī)技術(shù)、自動(dòng)控制技術(shù)和通訊技術(shù)而發(fā)展起來的一種新型的工業(yè)控制裝置它具有可靠性高、編程簡(jiǎn)單、維護(hù)方便等優(yōu)點(diǎn)已在工業(yè)控制領(lǐng)域得到廣泛地應(yīng)用因?yàn)樽詣?dòng)售貨機(jī)作為社會(huì)上完成商品零售和綜合服務(wù)的獨(dú)立設(shè)施要求它的結(jié)構(gòu)必須可靠、穩(wěn)定和執(zhí)行效率高。自動(dòng)售貨機(jī)具有不受任何場(chǎng)地限制，方便快捷，可以每天 24h 售貨的優(yōu)點(diǎn)。s lives brought great convenient, and therefore its reliable and stable design, highlights the importance of vending machines are to be pleted no vending, optical, mechanical, electrical integration of business automation equipment. Vending machines have not any space restrictions, convenient advantage of can 24h daily sales. For vending machine design a control system with reliable performance, wide voltage range and easy programming, easy to maintain. Vending machine for the automated business representatives are widely used in public places. The traditional vending machine control system using SCM as the control so that not only will do a great job with the ratio of the input and output interfaces and immunity system is relatively poor, it is also very cumbersome to maintain, and expensive. Programmable Logic Controller (PLC) is a bination of puter technology, automatic control technology and munication technology and a new type of industrial control devices developed its high reliability, simple programming, and easy maintenance have been in the field of industrial control vending machines widely used because of the pletion of the munity as a retail and integrated services independent facilities require it to be reliable structure, high stability and efficiency. Development of PLC and puter technology, semiconductor technology, control is closely related to the development of technology, digital technology, hightech munications work technology, the development of these hightech promote the development of PLC, the PLC and the development of these hightech a higher update request promote their development. 2 From the perspective of the development trend of the vending mac
