3500/44M本特利3500/44M3500/44M本特利3500/44M

編程器組成：聲明表：屬于塊，為塊聲明變量和參數(shù)；代碼區(qū)：包含程序本身；編程元件：可選打開或關(guān)閉，內(nèi)容依賴于所選擇的編程語言，雙擊插入或拖拉插入。
VIEW菜單：可切換到另一種語言，并可實(shí)現(xiàn)LAD/FBD/STL之間的轉(zhuǎn)換，要知道，LAD/FBD轉(zhuǎn)換成STL的，在語句表中可能不是zui有效程序。而STL轉(zhuǎn)換成其他則不一定行，轉(zhuǎn)換不了的仍用語句表示，轉(zhuǎn)換過程絕不會(huì)丟失程序。
其他菜單由于篇幅較大，請(qǐng)結(jié)合教材及軟件自己熟悉。
在討論調(diào)用塊前先介紹一下OB1塊——主循環(huán)塊，不能改名或刪除，它是由操作系統(tǒng)循環(huán)調(diào)用，可以訪問其他的S7程序塊，它包括自身程序和其他塊的調(diào)用。所以，當(dāng)我們編輯好一個(gè)塊以后，如FC1，為了讓新塊集成在CPU中的循環(huán)程序中，必須在OB1中調(diào)用。即在OB1中CALL F1。 子程序（新塊FC 1）執(zhí)行的條件有以下三個(gè)：已經(jīng)下載到PLC中，必須在OB1調(diào)用，PLC處于運(yùn)行狀態(tài)。 下載到實(shí)際的PLC時(shí)，我們可以選擇所有塊或其中的一個(gè)或幾個(gè)，再Download到PLC中。
程序的執(zhí)行過程：當(dāng)PLC得電或從STOP切換到RUN模式，CPU會(huì)執(zhí)行一次全啟動(dòng)（使用OB100）在全啟動(dòng)期間，操作系統(tǒng)清除非保持位存儲(chǔ)器、定時(shí)器和計(jì)數(shù)器，刪除中斷堆箋和塊堆箋，復(fù)位所有保存的硬件中斷，并啟動(dòng)掃描循環(huán)監(jiān)視時(shí)間。
CPU的循環(huán)操作包括三個(gè)主要部分：CPU檢查輸入信號(hào)的狀態(tài)并刷新過程影象輸入表（PII..）；執(zhí)行用戶程序，也就是OB1中的程序及一些事件（中斷等）；把過程輸出影象輸出表（PIQ）寫到輸出模塊。上面所提到的PII/PIQ是CPU中特定的存儲(chǔ)器，用來保存輸入模塊/輸出模塊的信號(hào)，在用戶程序中檢查時(shí)，可以保證在一個(gè)掃描周期內(nèi)為同樣的信號(hào)狀態(tài)。

程序結(jié)構(gòu)：上面曾經(jīng)提到過，一個(gè)比較簡(jiǎn)單的程序，我們可以不用各種子程序塊（如FC.FB），而是直接把整個(gè)程序直接寫在一個(gè)塊上（通常是OB1主塊上），CPU逐條的處理指令，我們稱這種叫線形編程；而對(duì)稍微有點(diǎn)復(fù)雜的程序，我們可以把它分成幾個(gè)塊，每塊包含處理一部分任務(wù)的程序，在每一個(gè)塊中可以進(jìn)一步分解、成幾個(gè)段，可以為相同類型的段生成段模塊，組織塊OB1包含按順序調(diào)用其他塊的指令，我們把這種方法叫分塊編程；另外，對(duì)可重復(fù)使用的功能裝入單個(gè)塊中，OB1（或其他塊）調(diào)用這些塊并傳遞相關(guān)參數(shù)，這種方法叫結(jié)構(gòu)化編程。用戶塊（程序塊）包括程序代碼和用戶數(shù)據(jù)，在結(jié)構(gòu)化程序中，一些塊循環(huán)調(diào)用處理，一些塊需要時(shí)才調(diào)用。程序塊共有組織塊（OB）、功能塊（FB）、功能（FC）、系統(tǒng)功能塊（SFB）和系統(tǒng)功能（FC）5種，其中系統(tǒng)塊是在CPU操作系統(tǒng)中預(yù)先定義好的功能和功能塊，這些塊不占用用戶程序空間。
