可靠工作的重要條件，可以避免偶然發(fā)生的電壓沖擊危害。接地線與機器的接地端相接，基本單元接地。如果要用擴展單元，其接地點應與基本單元的接地點接在一起。為了抑制加在電源及輸入端、輸出端的干擾，應給可編程控制器接上專用地線，接地點應與動力設備（如電機）的接地點分開。若達不到這種要求，也必須做到與其他設備公共接地，禁止與其他設備串聯(lián)接地。接地點應盡可能*近 PLC。2.4 The direct current 24 Vs connects line to carry2.4 直流 24V 接線端When usage had no importation spare part that the source touches to order, the PLC internal 24 V power supply passes the electric current that the importation spare part carries to provide to order a 7 mAs each time toward the importation.外文翻譯資料7使用無源觸點的輸入器件時，PLC 內(nèi)部 24V 電源通過輸入器件向輸入端提供每點 7mA 的電流。The PLC 24 Vs connects line to carry son, can also outwardly the department spread the feeling machine(if near to the switch or the light electricity switch) to provide electric current.When 24 Vs carried son to make to spread the feeling machine power supply, the COM carry Son is the direct current 24 V ground carry.If the adoption expands seaman, then should basic unit with expand the 24 Vs of the unit to carry to link.Moreover, any exterior power supply can't connect Arrive this carries son.PLC 上的 24V 接線端子，還可以向外部傳感器（如接近開關(guān)或光電開關(guān)）提供電流。24V 端子作傳感器電源時，COM 端子是直流 24V 地端。如果采用擴展船員，則應將基本單元和擴展單元的 24V 端連接起來。另外，任何外部電源不能接到這個端子。If took place to carry phenomenon, the electric voltage will drop into automatically, that importation has no effect to the programmable controller.如果發(fā)生過載現(xiàn)象，電壓將自動跌落，該點輸入對可編程控制器不起作用Each the importation amount of point of PLC of model number is to have provision of.Order to each importation that haven't yet use, it doesn't consume an electricity, so in this kind of case, the 24 V power supply carry Son outwardly the power supply flow of the ability can increase.每種型號的 PLC 的輸入點數(shù)量是有規(guī)定的。對每一個尚未使用的輸入點，它不耗電，因此在這種情況下，24V 電源端子向外供電流的能力可以增加The empty of the FX series PLC carries son, can't use under all circumstances.FX 系列 PLC 的空位端子，在任何情況下都不能使用。外文翻譯資料82.5 The importation connects line2.5 輸入接線The PLC accepts a route of travel switch generally,the limit switch etc. the switch of the importation quantity signal.Importation's connecting line to carry son is the port that the PLC and exterior spread the feeling machine load conversion signal.Lose Go in to connect line, general the exterior spread the feeling machine and input a port to connect line.PLC 一般接受行程開關(guān)、限位開關(guān)等輸入的開關(guān)量信號。輸入接線端子是PLC 與外部傳感器負載轉(zhuǎn)換信號的端口。輸入接線，一般指外部傳感器與輸入端口的接線。Input the spare part can be any NPN tube that have no source to touch to order or gather electrode to open a new road.Input When the spare part connect, input to carry to connect, input circuit to shut to match, input in the meantime輸入器件可以是任何無源的觸點或集電極開路的 NPN 管。輸入器件接通時，輸入端接通，輸入線路閉合，同時輸入指示的發(fā)光二極管亮。The give out light of designation diode is bright.An electric circuit that the importation carry with of two electric circuits, the adoption light electricity matches insulation.Two electric circuits take the RC filter, in order to prevent touch to order to tremble to move because of the importation or from the importationThe circuit string the electricity voice for go into cause PLC mistake action.輸入端的一次電路與二次電路之間，采用光電耦合隔離。二次電路帶 RC 濾波器，以防止由于輸入觸點抖動或從輸入線路串入的電噪聲引起 PLC 誤動作。外文翻譯資料9If Be inputting to touch some electric circuit to establish diode, should be small at establishing the electric voltage of the diode in the 4 Vs.If use to take the tongue switch of give out light the diode, establish diode Number can't more than twos. Moreover, importation's connecting line should also notice specially the following what time:若在輸入觸點電路串聯(lián)二極管，在串聯(lián)二極管上的電壓應小于 4V。若使用帶發(fā)光二極管的舌簧開關(guān)，串聯(lián)二極管的數(shù)目不能超過兩只。另外，輸入接線還應特別注意以下幾點：(1) The importation connects line and want generally over the 30 ms.But if the environment interference is smaller, when the electric voltage doesn't greatly decline, the importation connects line appropriate grow some.(2) Importation,output line and can't use the same root of electric cable, input,output line to want separate.(3) The width of the pulse signal that the programmable controller can accept, should be big in scan time of the period.（1） 輸入接線一般不要超過 30m。但如果環(huán)境干擾較小，電壓降不大時，輸入接線可適當長些。（2） 輸入、輸出線不能用同一根電纜，輸入、輸出線要分開。（30 可編程控制器所能接受的脈沖信號的寬度，應大于掃描周期的時間2.6 The exportation connects line2.6 輸出接線外文翻譯資料10(1) The programmable controller outputted after the electric appliances,the tube output,the transistor output 3 kinds of forms.(2) The exportation carries to connect line to is divided into independence to output with the public exportation.When the PLC exportation acts after the electric appliances or the tube, same two exportations of number carry to connect.At Can adopt the exportation electric voltage of different type and the electric voltage grade in the different set.But can use same type at same exportation in the set,same power supply of electric voltage grade.(3) Because the PLC exportation component is seal to pack in printing to make circuit board, and links to carry the son plank, if output conjunction the load short circuit of the component, will destroy by fire to print to make Circuit board, therefore apply the fuse protection to output a component.(4) Adoption after When the electric appliances output, bear of the electricity sensitive faculty load the size influence to after the work life span of the electric appliances, therefore after electric appliances work the life span request long.(5) The PLC exportation load may produce the voice interference, so want to adopt measure to take in to control. In addition, for can use the door result in injury of dangerous load, in addition to taking in to consider in the control the procedure, should also design exterior to park the car electric circuit urgently, make can While weaving the distance controller occurrence breakdown, the ability will cause injury of the load power supply cut off.Communicate the exportation line and direct current outputs line and doesn't use same electric cable, output the line should keep off the high pressure line and the motive line as far as possible, avoiding proceed together.（1）可編程控制器有繼電器輸出、晶閘管輸出、晶體管輸出 3 種形式。（2）輸出端接線分為獨立輸出和公共輸出。當 PLC 的輸出繼電器或晶閘管動作時，同一號碼的兩個輸出端接通。在不同組中，可采用不同類型和電外文翻譯資料11壓等級的輸出電壓。但在同一組中的輸出只能用同一類型、同一電壓等級的電源。（3）由于 PLC 的輸出元件被封裝在印制電路板上，并且連接至端子板，若將連接輸出元件的負載短路，將燒毀印制電路板，因此，應用熔絲保護輸出元件。（4）采用繼電器輸出時，承受的電感性負載大小影響到繼電器的工作壽命，因此繼電器工作壽命要求長。（5）PLC 的輸出負載可能產(chǎn)生噪聲干擾，因此要采取措施加以控制。此外，對于能使用戶造成傷害的危險負載，除了在控制程序中加以考慮之外，還應設計外部緊急停車電路，使得可編程控制器發(fā)生故障時，能將引起傷害的負載電源切斷。交流輸出線和直流輸出線不要用同一本電纜，輸出線應盡量遠離高壓線和動力線，避免并行。3 Conclusion3 結(jié)語The PLC shows the advantage of the but useds for the industry control extensively with it, it applies the problem for involve physically a lot of, this text just it the spot install and support the problem put forwardSome regulations, provide to be engaged in the PLC design and application a personnel a reference.外文翻譯資料12PLC 以其顯著的優(yōu)點而廣泛用于工業(yè)控制，其實際應用涉及的問題很多，本文只是就其現(xiàn)場安裝和維護問題提出了一些注意事項，供從事 PLC 設計及應用人員參考。
