西門(mén)子PLC S7-200的尋址方式
S7-200編程語(yǔ)言的基本單位是語(yǔ)句，而語(yǔ)句的構(gòu)成是指令，每條指令有兩部分：一部分是操作碼，另一部分是操作數(shù)。操作碼是指出這條指令的功能是什么，操作數(shù)則指明了操作碼所需要的數(shù)據(jù)所在。所謂尋址，就是尋找操作數(shù)的過(guò)程。S7-200 CPU的尋址分三種：立即尋址、直接尋址、間接尋址。
1．立即尋址
在一條指令中，如果操作碼后面的操作數(shù)就是操作碼所需要的具體數(shù)據(jù)，這種指令的尋址方式就叫立即尋址。
如：在傳送指令中：MOV IN OUT——操作碼“MOV”指出該指令的功能把IN中的數(shù)據(jù)傳送到OUT中，其中IN——源操作數(shù)，OUT——目標(biāo)操作數(shù)。
若該指令為：MOVD 2505 VD500
功能：將十進(jìn)制數(shù)2505傳送到VD500中，這里2505就是源操作數(shù)。因這個(gè)操作數(shù)的數(shù)值已經(jīng)在指令中了，不用再去尋找，這個(gè)操作數(shù)即立即數(shù)。這個(gè)尋址方式就是立即尋址方式。而目標(biāo)操作數(shù)的數(shù)值在指令中并未給出，只給出了要傳送到的地址VD500，這個(gè)操作數(shù)的尋址方式就是直接尋址。
2．直接尋址
在一條指令中，如果操作碼后面的操作數(shù)是以操作數(shù)所在地址的形式出現(xiàn)的，這種指令的尋址方式就叫直接尋址。
如：MOVD VD400 VD500
功能：將VD400中的雙字?jǐn)?shù)據(jù)傳給VD500
3．間接尋址
在一條指令中，如果操作碼后面的操作數(shù)是以操作數(shù)所在地址的地址形式出現(xiàn)的，這種指令的尋址方式就叫間接尋址。
如：MOVD 2505 *VD500
*VD500是指存放2505的地址的地址。
如VD500中存放的是VB0，則VD0則是存放2505的地址。
該指令的功能：將十進(jìn)制數(shù)2505傳送給VD0地址中。
