描述

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。

2.4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。

3、編程練習(xí)

（1）為了提高效率，當(dāng)A、B兩罐液體排空后，關(guān)閉泵3、4后，即開始重新注入A、B兩種液體，其他條件不變。

（2）如果四個(gè)罐不成比例，試重新編寫順序功能圖。

（3）嘗試采用基本指令完成該化學(xué)反應(yīng)控制程序。
