Currently the HMI factory is also more and more, the function is also more and more strong, the price is also more and more low, and the noodles of the usage are wide more and more. The HMI foreground can say that think 176。t guarantee the equipments by the control of the single machine, but pass the information exchanges of the equipments and equipments to attain the result that we want. For example fore pack and the examination of the empress work preface, we will arrive wrapping information feedback to examine the place, and examine the information of the place to also want the feedback to packing. Pass the information share thus to make both the chain connect, being a total body, the match of your that thus make is more close, at each other attain to reflect the result that mutually flick. The PLC correspondence has already e more body now its value, at the PLC and correspondence between PLCs, can pass the munication of the information and the share of the dates to guarantee that of the equipments moderates mutually, the result that arrive already to repair with each other. Data conversion the adoption RS232 between PLC connect to e to the transmission data, but the RS232 pick up a people and can guarantee 10 meters only of deliver the distance, if in the distance of 1000 meters we can pass the RS485 to carry on the correspondence, the longer distance can pass the MODEL only to carry on deliver. The PLC data transmission is just to be called a form to it in a piece of and continuous address that the data of the inner part delivers the other party, we, the PLC of the other party passes to read data in the watch to carry on the operation. If the data that data in the watch is a to establish generally, that is just the general data transmission, for example today of oil price rise, I want to deliver the price of the oil price to lose the oil ally on board, that is the share of the data。西門子 S7200PLC 入門 [M] 北京：北京航空航天大學(xué)出版社，2021 【 3】 周美蘭，周封，忘岳宇在設(shè)計(jì)中我們用到了光電開關(guān)、電磁閥、執(zhí)行機(jī)構(gòu)等我們沒怎么接觸過的電子器件，之前我對(duì)這些元器件不是很了解，由于在設(shè)計(jì)中用到了，我查閱了一些資料，對(duì)它們的原理以及應(yīng)用有了深刻地認(rèn)識(shí)。如在出食品五角，則綠燈閃爍。它與電器控制線路圖相似， 如圖 34所示。售貨機(jī)的基本功能就 是對(duì)投入的貨幣進(jìn)行運(yùn)算，并根據(jù)貨幣數(shù)值判斷是否能夠購買某種商品，并作出相應(yīng)的反應(yīng)。 PLC 的特點(diǎn) （ 1）抗干擾能力強(qiáng)，可靠性好 I/O 系統(tǒng)設(shè)計(jì)有完善的通道保護(hù)與信號(hào)調(diào)理電路；在結(jié)構(gòu)上對(duì)耐熱、防潮、防塵、抗震等都有周到的考慮。美國的幾個(gè)廠家為德州食品公司、通用電器公司、歌德公司、數(shù)字設(shè)備公司等。所以設(shè)計(jì)自動(dòng)售貨機(jī)是非常必要的。 從自動(dòng)售貨機(jī)的發(fā)展趨勢(shì)來看，它的出現(xiàn)是由于勞動(dòng)密集型的產(chǎn)業(yè)構(gòu)造向技術(shù)密集型社會(huì)轉(zhuǎn)變的產(chǎn)物。 文中詳盡地介紹了自動(dòng)售貨機(jī)的各硬件組成，并完成了 PLC 外部接線圖。但由于售貨機(jī)分布零散、范圍廣闊的特點(diǎn)，自動(dòng)售貨機(jī)在為消費(fèi)者帶來方便的同時(shí)，也為經(jīng)營者在監(jiān)控、管理、維護(hù)等方面帶來很大的不便。硬件主要由中央處理器 CPU、存貯器、輸入 /輸出單元以及編程器、電源和智能輸入 /輸出單元等構(gòu)成。 PLC 的工作原理 PLC 的工作原理與計(jì)算機(jī)的工作原理基本是一致的，可以簡(jiǎn)單地表述為在系統(tǒng)程序的管理下，通過運(yùn)行應(yīng)用程序完成用戶任務(wù)。 （ 4）功能完善 在 PLC 內(nèi)部具有許多控制功能，諸如時(shí)序、計(jì)算機(jī)、主控繼電器以及移位寄存器、中間寄存器等。當(dāng)按下選擇 A 商品的價(jià)格時(shí)，售貨機(jī)進(jìn)行減法運(yùn)算，從投入的貨幣總值中減去 A商品的價(jià)格同時(shí)啟動(dòng)相應(yīng)的電機(jī)，提取 A 號(hào)商品到出貨口。 在梯形圖中，有兩根豎直的直線，被稱為母線，現(xiàn)在很多 PLC 只 保留了左邊的母線，而把右邊的母線略去不寫。同理，網(wǎng)絡(luò) 8 至網(wǎng)絡(luò) 12 是食品一元控制程序，網(wǎng)絡(luò) 13 至網(wǎng)絡(luò) 17 是飲料一元控制程序，網(wǎng)絡(luò)18 至網(wǎng)絡(luò) 22 是飲料兩元控制程序，網(wǎng)絡(luò) 23 至網(wǎng)絡(luò) 27 是日用兩元控制程序，網(wǎng)絡(luò) 28 至網(wǎng)絡(luò) 32 是日用三元控制程序。 自動(dòng)售貨機(jī)是由于勞動(dòng)密集型的產(chǎn)業(yè)構(gòu)造 向技術(shù)密集型社會(huì)轉(zhuǎn)變的產(chǎn)物?？删幊炭刂破髟砑皯?yīng)用t satisfied with the current manufacturing industry foreground, also can39。 A work of half is also 2 and can send out similar to accept the data, but can39。 The saving machine can deposit the data that the I/ O input in the saving machine, and in work adjusting to bee tired to add the machine and I/ Os to connect, saving machine separately saving machine RAM of the procedure saving machine ROM and dates, the ROM can do deposit of the data permanence in the saving machine, but RAM only for the CPU putes the temporary calculation usage of hour of buffer space. The PLC anti interference is very and excellent, our root need not concern its service life and the work situation bad, these all problems have already no longer bee the topic that we fail, but stay to our is a concern to e to internal resources of make use of the PLC to strengthen the control ability of the equipments for us, make our equipments more gentle. PLC language is not we imagine of edit collected materials the language or language of Cs to carry on weaving the distance, but the trapezoid diagram that the adoption is original after the electric appliances to control, make the electrical engineering teacher while weaving to write the procedure very easy prehended the PLC language, and a lot of non electricity professional also very quickly know and go deep into to the PLC. Is PLC one of the advantage above and only, this is also one part that the people prehend more and easily, in a lot of equipments, the people have already no longer hoped to see too many control buttons, they damage not only and easily and produce the artificial error easiest, small is not a main error perhaps you can sti
