PLC梯形圖中的某些編程元件沿用了繼電器這一名稱，如輸入繼電器、輸出繼電器、內部輔助繼電器等，但是它們不是真實的物理繼電器(即硬件繼電器)，而是在軟件中使用的編程元件。每一編程元件與PLC存儲器中元件映像寄存器的二個存儲單元相對應。以輔助繼電器為例，如果該存儲單元為0狀態，梯形圖中對應的編程元件的線圈“斷電”，其常開觸點斷開，常閉觸點閉合，稱該編程元件為0狀態，或稱該編程元件為OFF(斷開)。該存儲單元如果為1狀態，對應編程元件的線圈“通電”，其常開觸點接通，常閉觸點斷開，稱該編程元件為l狀態，或稱該編程元件為ON(接通)。
2)根據梯形圖中各觸點的狀態和邏輯關系，求出與圖中各線圈對應的編程元件的ON/OFF狀態，稱為梯形圖的邏輯解算。邏輯解算是按梯形圖中從上到下、從左至右的順序進行的。解算的結果，馬上可以被后面的邏輯解算所利用。邏輯解算是根據輸入映像寄存器中的值，而不是根據解算瞬時外部輸入觸點的狀態來進行的。

本裝置為兩種液體混合裝置，SL1、SL2、SL3為液面傳感器，液體A、B閥門與混合液閥門由電磁閥YV1、YV2、YV3控制，M為攪動電機，控制要求如下：
初始狀態:裝置投入運行時，液體A、B閥門關閉，混合液閥門打開20秒將容器放空后關閉。
啟動操作:按下啟動按鈕SB1，裝置就開始按下列約定的規律操作：
液體A閥門打開，液體A流入容器。當液面到達SL2時，SL2接通，關閉液體A閥門，打開液體B閥門。液面到達SL1時，關閉液體B閥門，攪動電機開始攪動。攪動電機工作6秒后停止攪動，混合液體閥門打開，開始放出混合液體。當液面下降到SL3時，SL3由接通變為斷開，再過2秒后，容器放空，混合液閥門關閉，開始下一周期。
停止操作:按下停止按鈕SB2后，在當前的混合液操作處理完畢后，才停止操作（停在初始狀態上）。
