PLC接線圖
按照輸入與輸出點(diǎn)的分配和項(xiàng)目描述的控制要求,設(shè)計(jì)PLC的接線圖如圖2所示。如用指示燈代替泵,用24V直流電作電源。若控制實(shí)際泵應(yīng)接220V交流,如圖中虛線部分。“□”表示控制泵的接觸器線圈或模擬中的指示燈。
程序設(shè)計(jì)
根據(jù)工藝要求設(shè)計(jì)出順序控制功能圖如圖3所示。圖中各步用狀態(tài)繼電器S表示,這里S作普通輔助繼電器使用,在進(jìn)入步進(jìn)程序之后,開始分別進(jìn)入A、B兩罐的A液、B液注入程序。由于B罐要進(jìn)行加熱,因此,比A罐要多一步。為了同時(shí)開始將A、B兩液體注入反應(yīng)罐C前,關(guān)掉A罐注入泵1,人為增加一個(gè)時(shí)間定時(shí)步,已完成對(duì)S10步的復(fù)位。
當(dāng)B罐加熱到60℃且T0延時(shí)到,開始進(jìn)入將A、B兩種液體注入C罐進(jìn)行反應(yīng)的S3步。在打開泵3、4輸送A、B兩種液體的同時(shí),攪拌器就開始攪拌,為了延續(xù)該動(dòng)作到反應(yīng)結(jié)束,采用SET指令。
當(dāng)A罐與B罐空,而C罐滿時(shí),注入結(jié)束。進(jìn)入反應(yīng)計(jì)時(shí)步S4。60s后反應(yīng)結(jié)束,C罐反應(yīng)液將通過泵5經(jīng)過濾器輸送到D罐。
當(dāng)D罐滿時(shí),C罐也應(yīng)空。D罐通過泵6排出,當(dāng)D罐空時(shí),循環(huán)以上過程。
運(yùn)行并調(diào)試程序
(1)將梯形圖程序輸入到計(jì)算機(jī)。
(2)下載程序到PLC,并對(duì)程序進(jìn)行調(diào)試運(yùn)行。
(3)調(diào)試運(yùn)行并記錄調(diào)試結(jié)果。
