L LW0 將循環(huán)次數(shù)計(jì)數(shù)器LW0的值裝入累加器1

在FC100中，寄存器間接尋址指令OP NDB[LW0]使用了臨時(shí)本地?cái)?shù)據(jù)LW0，變量表中定義的臨時(shí)變量雖然也在L堆棧中，但不能用于存儲(chǔ)器間接尋址，從這里也可看出臨時(shí)本地?cái)?shù)據(jù)與臨時(shí)變量的區(qū)別。程序中LW2、LD4和LD8起的作用也可用臨時(shí)變量替代。
下面舉例說(shuō)明如何使用FC100。在某應(yīng)用中，機(jī)架0的4號(hào)槽位安裝了一個(gè)8模入模塊(地址256開(kāi)始)，若要將前6個(gè)模入模塊信號(hào)讀回，存入DB50.DBW10開(kāi)始的6個(gè)字單元中，可按下列形式調(diào)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(chǔ)器中，用戶(hù)可在存儲(chǔ)器中建立一個(gè)或多個(gè)數(shù)據(jù)塊。每個(gè)數(shù)據(jù)塊可大可小，但CPU對(duì)數(shù)據(jù)塊數(shù)量及數(shù)據(jù)總量有限制，如對(duì)于CPU314，用作數(shù)據(jù)塊的存儲(chǔ)器多為8 KB(8192 B)，用戶(hù)定義的數(shù)據(jù)總量不能超出這個(gè)限制。對(duì)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(cuò)誤。
1. 定義數(shù)據(jù)塊
在編程階段和運(yùn)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(kāi)發(fā)軟件包定義的，定義內(nèi)容包括數(shù)據(jù)塊號(hào)及塊中的變量(包括變量符號(hào)名、數(shù)據(jù)類(lèi)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(lèi)型決定了數(shù)據(jù)塊的數(shù)據(jù)結(jié)構(gòu)，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(hù)程序的一部分下載到CPU中。
