(1) 功能塊FC實(shí)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(chǔ)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(chǔ)臨時(shí)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(shí)，先前塊的信息存儲(chǔ)在塊堆棧中，臨時(shí)變量彈出L堆棧。
因?yàn)楣δ軌KFC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(shí)參。
STEP 7為功能塊FC提供了一個(gè)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(shí)，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(duì)文本文件進(jìn)行編譯時(shí)，STEP 7會(huì)自動(dòng)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(shí)，可在FC的變量聲明表中聲明一個(gè)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(duì)功能塊編程分兩步進(jìn)行：步是定義局部變量(填寫(xiě)局部變量表)；第二步是編寫(xiě)要執(zhí)行的程序，可以用梯形圖或語(yǔ)句表兩種形式編程，并在編程過(guò)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(shí)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(duì)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(dòng)產(chǎn)生局部變量地址(Address)。
寫(xiě)功能塊程序時(shí)，可以用以下兩種方式使用局部變量：
(1) 使用變量名，此時(shí)變量名前加前綴“#”，以區(qū)別于在符號(hào)表中定義的符號(hào)地址。增量方式下，前綴會(huì)自動(dòng)產(chǎn)生。
(2) 直接使用局部變量的地址，這種方式只對(duì)背景數(shù)據(jù)塊和L堆棧有效。
在調(diào)用FB塊時(shí)，要說(shuō)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(shí)，STEP 7會(huì)自動(dòng)提醒并生成背景數(shù)據(jù)塊。此時(shí)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(chǔ)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(duì)不同的輸入位進(jìn)行二分頻處理。以下給出了FC10的變量聲明表和語(yǔ)句表程序。在程序中使用了跳變沿檢測(cè)指令。
