【導讀】可編程邏輯控制器或可編程控制器是一種用于機電過程自動化的數字計算機，如工廠的裝配線，控制機械游樂設施，或照明燈具。PLC應用在許多工業(yè)和機器。程序控制機器操作通常存儲在備用電池或非易失性存儲器。的一個例子，因為輸出必須響應輸入條件的有限時間內，否則會導致意想不到的結果。PLC是應美國汽車制造行業(yè)的需要發(fā)明了。訂取代硬連線控制面板重新布線時生產模式改變了。和昂貴的，作為電工需要單獨改變每個繼電器。獲獎的提案來自貝德福德聯(lián)營公司的貝德福德，馬薩諸塞州。定084因為是貝德福德聯(lián)營公司的四分之八十個項目，結果。一個非常084建立的模型現(xiàn)在陳列在Modicon總部設在北安多佛，馬薩諸塞州。由通用汽車公司提出了Modicon，當單位是經過近二十年的不間斷服務退休。用84的名字在其產品范圍的結束，直到984出現(xiàn)。這一計劃符號的選擇，以減少對現(xiàn)有技術人員的培訓需求。于調試和故障排除的PLC軟件的功能，
【正文】 eration ability, and can read the procedure save the contents of the machine to drive the homologous saving machine and I/O connect after pass the calculation。 The I/O add inner part is tired the input and output system ofThe 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。 But lead even is a fatal error greatly is what we can39。t is tolerant of. New technique always for bringing more safe and convenient operation for us, make we 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。s power, the one who make operate reduces the otiose error. 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
