<P>除了通常用于 WAN(廣域網(wǎng))外,用戶也可將 WinCC WebNavigator 應(yīng)用到必須以zui小成本實(shí)施的項(xiàng)目中。 這包括那些具有明確分布式結(jié)構(gòu)(例如水/污水處理)或只是偶爾訪問過程信息(樓宇管理)的應(yīng)用場合。 除此以外,用戶也可將 Web 客戶端用作局域網(wǎng)上的常規(guī)操作員站。</P>
<P><EM>Web 服務(wù)器和客戶端<BR></EM>對于 Web 解決方案來說,需要將 WebNavigator 安裝在 WinCC 單用戶系統(tǒng)或服務(wù)器上,將 WebNavigator 客戶端安裝在任意 Windows PC 上。 這樣,用戶可通過自己的 Internet 客戶端、Microsoft Internet Explorer 或通過終端服務(wù)來操作和監(jiān)視正在運(yùn)行的 WinCC 項(xiàng)目,而無需在計(jì)算機(jī)上安裝 WinCC 基本系統(tǒng)。</P>
<P>連接到 Web 服務(wù)器的 Web 客戶端可以在任何位置訪問工廠內(nèi)所有(zui多 12 臺)WinCC 服務(wù)器的項(xiàng)目。 這些項(xiàng)目可以同時顯示在不同的選項(xiàng)卡中,例如,通過 Microsoft Internet Explorer(V7 或更高版本)的多選項(xiàng)卡功能。</P>
<P><EM>可供選用的安*方案<BR></EM>WinCC 服務(wù)器和網(wǎng)絡(luò)服務(wù)器的分離已經(jīng)有效提高了系統(tǒng)的安全性和可用性,除此以外還可以通過在兩個單獨(dú)的 SCADA 客戶端上采用兩臺單獨(dú)的網(wǎng)絡(luò)服務(wù)器進(jìn)一步提高系統(tǒng)的安全性和可用性。 基于 Web 的操作員站是現(xiàn)場工廠用戶管理系統(tǒng)的組成部分。 不同的*等級決定了哪個用戶具有訪問權(quán)。</P>
<P>依據(jù)所擁有的訪問權(quán),操作員可以只是查看工廠(僅監(jiān)視)或者執(zhí)行部分/全部操作。 可以通過系統(tǒng)報(bào)警跟蹤每次登錄和注銷。</P>
<P><EM>瘦客戶端解決方案<BR></EM>通過采用 Microsoft Terminal Services 的瘦客戶端解決方案,用戶還可以連接運(yùn)行 Windows 操作系統(tǒng)(例如 Windows 9x/ME)的簡單 PC、堅(jiān)固耐用的現(xiàn)場設(shè)備(例如 SIMATIC 瘦客戶端)和基于 Windows CE 的移動客戶端(PDA,個人數(shù)字助理)。 由于客戶端僅提供畫面顯示,而應(yīng)用程序本身,即 WebNavigator 客戶端在 Windows 下的終端服務(wù)器上運(yùn)行,因此此類解決方案的硬件要求不高。 一臺終端服務(wù)器上zui多可連接 25 臺瘦客戶端。</P>
<P>與典型 WebNavigator 安裝形式不同,瘦客戶端通常與服務(wù)器同在一個局域網(wǎng)上。</P></DIV></DIV>
