組態(tài)王與現(xiàn)場(chǎng)的I/O設(shè)備直接進(jìn)行通訊。如圖3所示
I/0設(shè)備的輸入提供現(xiàn)場(chǎng)的信息,例如產(chǎn)品的位置、機(jī)器的轉(zhuǎn)速、爐溫等等。I/O設(shè)備的輸出通常用于對(duì)現(xiàn)場(chǎng)的控制,例如啟動(dòng)電動(dòng)機(jī)、改變轉(zhuǎn)速、控制閥門和指示燈等等。有些I/O設(shè)備(例如PLC),其本身的程序完成對(duì)現(xiàn)場(chǎng)的控制,程序根據(jù)輸入決定各輸出的值。
輸入輸出的數(shù)值存放在I/O設(shè)備的寄存器中,寄存器通過其地址進(jìn)行引用。大多數(shù)I/O設(shè)備提供與其他設(shè)備或計(jì)算機(jī)進(jìn)行通一訊的通訊端口或數(shù)據(jù)通道,組態(tài)王通過這些通訊通道讀寫I/0設(shè)備的寄存器,采集到的數(shù)據(jù)可用于進(jìn)一步的監(jiān)控。不需要讀寫I/O設(shè)備的寄存器,組態(tài)王提供了一種數(shù)據(jù)定義方法,定義了I/O變量后,可直接使用變量名用于系統(tǒng)控制、操作顯示、趨勢(shì)分析、數(shù)據(jù)記錄和報(bào)警顯示。
3 組態(tài)王的組成及其應(yīng)用
3.1組態(tài)王軟件的組成
?。?)工程管理器,(2)工程瀏覽器,(3)組態(tài)王畫面開發(fā)系統(tǒng),(4)畫面運(yùn)行系統(tǒng)TOUCHVEW,(5)信息窗口。
3.2 組態(tài)王在計(jì)算機(jī)監(jiān)控系統(tǒng)中的應(yīng)用
1.用組態(tài)王建立應(yīng)用程序項(xiàng)目的一般過程
?。?)制作圖形畫面
(2)構(gòu)造數(shù)據(jù)庫;①數(shù)據(jù)庫的作用,②數(shù)據(jù)詞典中變量的類型。
?。?)定義動(dòng)畫連接;動(dòng)畫連接是指在畫面的圖形對(duì)象與數(shù)據(jù)庫的數(shù)據(jù)變量之間建立一種關(guān)系,當(dāng)變量的值改變時(shí),在畫面上以圖形對(duì)象的動(dòng)畫效果表示出來:或者由軟件使用者通過圖形對(duì)象改變數(shù)據(jù)變量的值。組態(tài)王提供了21種動(dòng)畫連接方式。一個(gè)圖形對(duì)象可以同時(shí)定義多個(gè)連接,組合成復(fù)雜的效果,以便滿足實(shí)際中任意的動(dòng)畫顯示需要。
?。?)運(yùn)行和調(diào)試;在組態(tài)王軟件的實(shí)時(shí)運(yùn)行環(huán)境TOUCHVEW中,運(yùn)行和調(diào)試在畫面制作系統(tǒng)中建立的動(dòng)畫圖形畫面。
