AB 1746-ITB16（一）分析被控對象并提出控制要求
詳細分析被控對象的工藝過程及工作特點，了解被控對象機、電、液之間的配合，提出被控對象對PLC控制系統(tǒng)的控制要求，確定控制方案，擬定設(shè)計任務(wù)書。
AB 1746-ITB16
PLC的編程及使用特點；
1．編程方法簡單易學
梯形圖是使用得zui多的PLC的編程語言，其電路符號和表達方式與繼電器電路原理圖相似，梯形圖語言形象直觀，易學易懂，熟悉繼電器電路圖的電氣技術(shù)人員只需花幾天時間就可以熟悉梯形圖語言，并用來編制用戶程序。
梯形圖語言實際上是一種面向用戶的高級語言，PLC在執(zhí)行梯形圖程序時，將它“翻譯”成匯編語言后再去執(zhí)行。
2．功能強，性能價格比高
一臺小型PLC內(nèi)有成百上千個可供用戶使用的編程元件，有很強的功能，可以實現(xiàn)非 常復(fù)雜的控制功能。與相同功能的繼電器系統(tǒng)相比，具有很高的性能價格比。PLC可以通過通信聯(lián)網(wǎng)，實現(xiàn)分散控制，集中管理。

3．硬件配套齊全，用戶使用方便，適應(yīng)性強
PLC產(chǎn)品已經(jīng)標準化、系列化、模塊化，配備有品種齊全的各種硬件裝置供用戶選用，用戶能靈活方便地進行系統(tǒng)配置，組成不同功能、不同規(guī)模的系統(tǒng)。PLC的安裝接線也很方便，一般用接線端子連接外部接線。PLC帶負載能力，可以直接驅(qū)動一般的電磁閥和中小型交流接觸器。
硬件配置確定后，通過修改用戶程序，就可以方便快速地適應(yīng)工藝條件的變化。
4．可靠性高，抗*力強
傳統(tǒng)的繼電器控制系統(tǒng)中使用了大量的中間繼電器、時間繼電器。由于觸點接觸不良，容易出現(xiàn)故障。PLC用軟件代替大量的中間繼電器和時間繼電器，僅剩下與輸入和輸出有關(guān)的少量硬件元件，接線可減少到繼電器控制系統(tǒng)的十分之一到百分之一，因觸點接觸不良造成的故障大為減少。
PLC使用了一系列硬件和軟件抗干擾措施，具有很強的抗*力，平均*時間達到數(shù)萬小時以上，可以直接用于有強烈干擾的工業(yè)生產(chǎn)現(xiàn)場，PLC大用戶*為zui可靠的工業(yè)控制設(shè)備之一。
5．系統(tǒng)的設(shè)計、安裝、調(diào)試工作量少
PLC用軟件功能取代了繼電器控制系統(tǒng)中大量的中間繼電器、時間繼電器、計數(shù)器等器件，使控制柜的設(shè)計、安裝、接線工作量大大減少。
PLC的梯形圖程序可以用順序控制設(shè)計法來設(shè)計。這種編程方法很有規(guī)律，很容易掌握。對于復(fù)雜的控制系統(tǒng)，如果掌握了正確的設(shè)計方法，設(shè)計梯形圖的時間比設(shè)計繼電器系統(tǒng)電路圖的時間要少得多。
可以在實驗室模擬調(diào)試PLC的用戶程序，輸入信號用小開關(guān)來模擬，可通過PLC發(fā)光二極管觀察輸出信號的狀態(tài)。完成了系統(tǒng)的安裝和接線后，在現(xiàn)場的統(tǒng)調(diào)過程中發(fā)現(xiàn)的問題一般通過修改程序就可以解決，系統(tǒng)的調(diào)試時間比繼電器系統(tǒng)少得多。
6．維修工作量小，維修方便
PLC的故障率很低，且有完善的自診斷和顯示功能。PLC或外部的輸入裝置和執(zhí)行機構(gòu)發(fā)生故障時，可以根據(jù)PLC上的發(fā)光二極管或編程器提供的信息方便地查明故障的原因，用更換模塊的方法可以迅速地排除故障。
7．體積小，能耗低
對于復(fù)雜的控制系統(tǒng)，使用PLC后，可以減少大量的中間繼電器和時間繼電器，小型PIC的體積僅相當于幾個繼電器的大小，因此可將開關(guān)柜的體積縮小到原來的l/2~1/10。
PLC控制系統(tǒng)的配線比繼電器控制系統(tǒng)的少得多，故可以省下大量的配線和附件，減少很多安裝接線工時，加上開關(guān)柜體積的縮小，可以節(jié)省大量的費用。
