L LW0 將循環(huán)次數(shù)計數(shù)器LW0的值裝入累加器1
LOOP NEXT 若累加器1的值不為0，將累加器減1繼續(xù)循環(huán)；若累加
器為0，則結束
在FC100中，寄存器間接尋址指令OP NDB[LW0]使用了臨時本地數(shù)據(jù)LW0，變量表中定義的臨時變量雖然也在L堆棧中，但不能用于存儲器間接尋址，從這里也可看出臨時本地數(shù)據(jù)與臨時變量的區(qū)別。程序中LW2、LD4和LD8起的作用也可用臨時變量替代。
下面舉例說明如何使用FC100。在某應用中，機架0的4號槽位安裝了一個8模入模塊(地址256開始)，若要將前6個模入模塊信號讀回，存入DB50.DBW10開始的6個字單元中，可按下列形式調用FC100：
CALL FC100
PIW_Add：= 256
CH_LEN：= 6
DB_No：= 50
DBW_Addr：= 10
數(shù)據(jù)塊
數(shù)據(jù)塊定義在S7 CPU存儲器中，用戶可在存儲器中建立一個或多個數(shù)據(jù)塊。每個數(shù)據(jù)塊可大可小，但CPU對數(shù)據(jù)塊數(shù)量及數(shù)據(jù)總量有限制，如對于CPU314，用作數(shù)據(jù)塊的存儲器多為8 KB(8192 B)，用戶定義的數(shù)據(jù)總量不能超出這個限制。對數(shù)據(jù)塊必須遵循先定義后使用的原則，否則，將造成系統(tǒng)錯誤。
1. 定義數(shù)據(jù)塊
在編程階段和運行程序中都能定義數(shù)據(jù)塊。大多數(shù)數(shù)據(jù)塊是在編程階段用STEP 7開發(fā)軟件包定義的，定義內容包括數(shù)據(jù)塊號及塊中的變量(包括變量符號名、數(shù)據(jù)類型以及初始值等)，定義完成后，數(shù)據(jù)塊中變量的順序及類型決定了數(shù)據(jù)塊的數(shù)據(jù)結構，變量的數(shù)量決定了數(shù)據(jù)塊的大小。數(shù)據(jù)塊在使用前，必須作為用戶程序的一部分下載到CPU中。
