(1) 功能塊FC實參的指針存到調(diào)用塊的L堆棧；
(2) 調(diào)用塊的地址和返回位置存儲在塊堆棧，調(diào)用塊的局部數(shù)據(jù)壓入L堆棧；
(3) 功能塊存儲臨時變量的L堆棧區(qū)被推入L堆棧上部；
(4) 當(dāng)被調(diào)用功能塊FC結(jié)束時，先前塊的信息存儲在塊堆棧中，臨時變量彈出L堆棧。
因為功能塊FC不用背景數(shù)據(jù)塊，不能分配初始數(shù)值給功能塊FC的局部數(shù)據(jù)，所以必須給功能塊FC提供實參。
STEP 7為功能塊FC提供了一個特殊的返回值輸出參數(shù)(關(guān)鍵字：RET_VAL)。當(dāng)在文本文件中創(chuàng)建功能塊FC時，你可以在定義功能塊FC命令后輸入數(shù)據(jù)類型(如BOOL或INT)。對文本文件進行編譯時，STEP 7會自動生成RET_VAL輸出參數(shù)。當(dāng)用STEP 7的程序編輯器(Program Editor)以增量模式創(chuàng)建功能塊FC時，可在FC的變量聲明表中聲明一個輸出參數(shù)RET_VAL，并指明其數(shù)據(jù)類型。
功能塊編程與調(diào)用舉例
對功能塊編程分兩步進行：步是定義局部變量(填寫局部變量表)；第二步是編寫要執(zhí)行的程序，可以用梯形圖或語句表兩種形式編程，并在編程過程中使用定義了的局部變量(數(shù)據(jù))。
定義局部變量的工作內(nèi)容包括：
(1) 分別定義形參、靜態(tài)變量和臨時變量(FC塊中不包括靜態(tài)變量)；
(2) 確定各變量的聲明類型(Decl.)、變量名(Name)和數(shù)據(jù)類型(Data Type)，還要為變量設(shè)置初始值(Initial Value)(盡管對有些變量初始值不一定有意義)。如果需要還可為變量注釋(Comment)。在增量編程模式下，STEP 7將自動產(chǎn)生局部變量地址(Address)。
寫功能塊程序時，可以用以下兩種方式使用局部變量：
(1) 使用變量名，此時變量名前加前綴“#”，以區(qū)別于在符號表中定義的符號地址。增量方式下，前綴會自動產(chǎn)生。
(2) 直接使用局部變量的地址，這種方式只對背景數(shù)據(jù)塊和L堆棧有效。
在調(diào)用FB塊時，要說明其背景數(shù)據(jù)塊。背景數(shù)據(jù)塊應(yīng)在調(diào)用前生成，其順序格式與變量聲明表必須保持一致。在增量方式下，調(diào)用FB塊時，STEP 7會自動提醒并生成背景數(shù)據(jù)塊。此時也為背景數(shù)據(jù)塊設(shè)置了初始值，該初始值與變量聲明表中的相同。當(dāng)然也可以為背景數(shù)據(jù)塊設(shè)置當(dāng)前值(Current Value)，即存儲在CPU中的數(shù)值。
1．二分頻器
假設(shè)功能塊FC10是二分頻器產(chǎn)生程序，功能是對不同的輸入位進行二分頻處理。以下給出了FC10的變量聲明表和語句表程序。在程序中使用了跳變沿檢測指令。
