1. 從左向右，從上向下掃描；

　　2. 搜索并執(zhí)行梯形圖上的每個運算符；

　　3. 檢查輸入變量的狀態(tài)；

　　4. 檢查每個運算符的狀態(tài)，如果為真，則執(zhí)行該運算符；

　　5. 將輸出變量的狀態(tài)更新為執(zhí)行運算符后的狀態(tài)；

　　6. 執(zhí)行完所有的運算符后，繼續(xù)掃描下一個周期。

　　需要注意的是，PLC梯形圖掃描是一個連續(xù)的循環(huán)過程。在掃描過程中，會不斷檢查輸入變量和運算符的狀態(tài)并進(jìn)行更新。這使得PLC在實時控制系統(tǒng)中具有很高的并發(fā)性和實時性，能夠快速響應(yīng)外部環(huán)境的變化。
