唐僧：徒兒們，這佛祖交待的DCS、PLC、數(shù)控系統(tǒng)要哪里買？誰(shuí)是正規(guī)的？
孫悟空：師傅，我用火眼金睛照過(guò)了，《福州聚福興自動(dòng)化有限公司》是正規(guī)的！他們開(kāi)在《福州倉(cāng)山》，這地方專做進(jìn)出口的，假不了！
唐僧：那產(chǎn)品怎么樣，值得信賴嗎？他們主要是做什么品牌的？
孫悟空：師傅，您放心這家的產(chǎn)品都是《的，無(wú)假貨》，而且《服務(wù)態(tài)度好，是個(gè)負(fù)責(zé)任的公司》，至于他們做得產(chǎn)品有......（此省略10000字），總之一句話：《只要有的品牌，他們都做》。
豬八戒：那價(jià)格怎么樣，可以留點(diǎn)錢買吃的嗎？
孫悟空：八戒你就知道吃，不過(guò)他們的《價(jià)格是同行里非常好》的！
沙悟凈：那要我去挑嗎？
孫悟空：不用，一般他們是《包郵》的！
唐僧：那還等什么，快去買，買完完成任務(wù)我就升官了。

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：

數(shù)據(jù)塊
數(shù)據(jù)塊定義在S7 CPU存儲(chǔ)器中，用戶可在存儲(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(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，必須作為用戶程序的一部分下載到CPU中。
