西門子控制系統(tǒng)特點(diǎn)：
1、良好的系統(tǒng)安全性和可靠性
系統(tǒng)的建立不破壞現(xiàn)有生產(chǎn)設(shè)備的成熟小閉環(huán)系統(tǒng)的運(yùn)行。系統(tǒng)采用分布式網(wǎng)絡(luò)結(jié)構(gòu)，網(wǎng)絡(luò)上任何一臺(tái)設(shè)備發(fā)生故障不影響其它設(shè)備的運(yùn)行。
2、系統(tǒng)具有完備的自診斷能力。
PLC設(shè)備對PLC本身和IO口均具有自診斷能力。網(wǎng)絡(luò)通訊系統(tǒng)均有檢驗(yàn)和應(yīng)答功能以及自診斷功能以保證通訊傳輸中的正確性。
3、計(jì)算機(jī)設(shè)置WATCHDOG技術(shù)防止程序“跑飛"。
系統(tǒng)構(gòu)成的所有硬件均采用國內(nèi)外公司的產(chǎn)品，這些產(chǎn)品在國內(nèi)許多企業(yè)已廣泛使用，實(shí)踐證明它們是成熟的產(chǎn)品。控制室采用觸摸屏系統(tǒng)平臺(tái)，為全自動(dòng)化改造的計(jì)算機(jī)聯(lián)網(wǎng)提供了良好的外部環(huán)境，同時(shí)也給公司的全面計(jì)算機(jī)管理創(chuàng)造了條件。監(jiān)控軟件支持全局?jǐn)?shù)據(jù)共享，每一臺(tái)新增的工作站都可以獲得所有數(shù)據(jù)而無須進(jìn)行復(fù)雜的系統(tǒng)規(guī)劃;開放性的軟件設(shè)計(jì)使得用戶能輕松開發(fā)出第三方接口。
