【正文】 t do other works.When you are reading the book, you hear someone knock on door, you stop to start up of affair, open the door and bine to continue with the one who knock on door a dialogue, the telephone of this time rang, you signal hint to connect a telephone, after connecting the telephone through, return overdo e together knock on door to have a conversation, after dialogue plete, you continue again to see your book, this kind of circumstance we are called the interruption to it, it has the authority, also having sex of have the initiative, the PLC had such function .Its characteristics lie in us and may meet the urgently abrupt affairs in the operation process of the equipments, we want to stop to start immediately up of work, the whereabouts manages the more important affair, this kind of circumstance is we usually meet of, PLC while carry out urgent mission, total will keep the current appearance first, for example the address of the procedure, CPU of tired add the machine data etc., be like to to stick down which the book that we see is when we open the door the page or simply make a mark, because we treat and would still need to continue immediately after book of see the behind. The CPU always does the affair that should do according to our will, but your mistake of give it an affair, it also would be same to do, this we must notice.The interruption is not only a, sometimes existing jointly with the hour several inside break, break off to have the preferred Class, they will carry out the interruption of the higher Class according to person39。t answer the phone, the other party also。 A work of half is also 2 and can send out similar to accept the data, but can39。 But take data in the watch for an instruction procedure that controls the PLC, that had the difficulty very much, for example you have to control one pedestal robot to press the action work that you imagine, you will draw up for it the form that a procedure bine with the data sends out to pass by.The form that information transport contain single work, the half a work and the difference of a workses .The meaning of the single work also is to say both, a can send out only, but a can receive only, for example a spy he can receive the designation of the superior only, but can39。 to be good very.At a lot of situations, the list is a smooth movement that can39。t is tolerant of. New technique always for bringing more safe and convenient operation for us, we make a lot of problems for face on sweep but light, do you understand the HMI Says the HMI here you basically not clear what it is, also have no interest understanding, change one inside text explains it into the touch to hold or manmachine interface you knew, it bines with the PLC to our larger space.HMI the control not only is reduced the control press button, increase the vivid of the control, more main of it is can sequence of, and at can the change data input to output the feedback with data, control in the temperature curve of imitate but also can keep the manifestation of view to e out. And can write the function help procedure through a plait to provide the help of various what lies in one39。 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 data, 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 still accept。s address and saving machine three big pieces to constitute, CPU core is from an or many is tired to add the machine to constitute, mathematics that they have the logic operation ability, and can read the procedure save the contents of the machine to drive the homologous saving machine and I/ Os to connect after pass the calculation。s brain and calculators, with the mode that person39。t guarantee the request of the higher quantity and high new the image of the technique business enterprise.The people see in produce practice, automate brought the tremendous convenience and the product quantities for people up of assurance, also eased the personnel39。 the operation that list depends the artificial has already can39。這篇畢業(yè)設(shè)計(jì)和大學(xué)三年中所有教育過(guò)我的老師也是分不開(kāi)的，沒(méi)有他們傳授的知識(shí)，我也不可能順利的完成這個(gè)課題，還有就老師對(duì)我在學(xué)習(xí)和生活上的幫助，也讓我深受感動(dòng)！總之，無(wú)論是在課程學(xué)習(xí)階段，還是在論文的選題，資料查詢和撰寫(xiě)的每一個(gè)環(huán)節(jié)，無(wú)不得到我的指導(dǎo)老師的照顧，我的組員的默契配合，以及和我一起做設(shè)計(jì)的同伴的無(wú)私幫助。在老師的悉心指導(dǎo)和大力幫助下，我得以順利的完成了這篇畢業(yè)設(shè)計(jì)。謝 辭三年的大學(xué)生活即將結(jié)束，三年中，在各科老師的精心指導(dǎo)下，我掌握了不少的專業(yè)知識(shí)和實(shí)踐經(jīng)驗(yàn)。該系統(tǒng)以感應(yīng)加熱基本原理為基礎(chǔ)，以臺(tái)達(dá)PLC為原型，應(yīng)用HMI和PLC構(gòu)成的數(shù)控系統(tǒng)，對(duì)雙工位淬火機(jī)床的進(jìn)行控制，理論上實(shí)現(xiàn)對(duì)工件的加熱處理，進(jìn)一步加工出符合工業(yè)要求的產(chǎn)品。如圖上半部分選定工件序號(hào)，輸入序號(hào)，然后輸入工件型號(hào)，把已知的工件型號(hào)輸入，修改工件名稱用來(lái)對(duì)工件名稱的修改；如圖下部分，設(shè)有選定工件，調(diào)入?yún)?shù)，保存參數(shù)，存工件名，和參數(shù)設(shè)置五個(gè)按鈕，選定工件運(yùn)行后宏設(shè)置：{BITOFF (1M26)}；存工件名運(yùn)行后宏設(shè)置：{BITOFF (1M29)}其中參數(shù)設(shè)置為換畫(huà)面按鈕。另外，設(shè)有上頁(yè)，下頁(yè)和返回三個(gè)換畫(huà)面按鈕，用于畫(huà)面的轉(zhuǎn)換。 系統(tǒng)參數(shù)畫(huà)面設(shè)計(jì)圖34 系統(tǒng)參數(shù)
