在工業控製係統中，上位機通常隻監控係統的運行，采集係統信號，以畫麵、報表、曲線等方式顯示係統狀態，簡單地下發一些開關量或模擬量信號，調節係統運行參數。而自控參數的運算由PLC或智能儀表來完成。其實紫金橋組態軟件完全能完成這些智能設備的功能，程序編寫也非常方便，減少設備投資。
下麵以某鍋爐供暖控製項目為例，介紹以紫金橋組態軟件為核心控製單元的工程的實現方法。
監控畫麵
下位設備情況
在本項目中被控設備包括：
兩台4MW燃氣鍋爐，鍋爐配套有控製台，帶有觸摸屏和西門子200PLC，
兩台1.5KW 的 補水 泵
兩台 15KW 的屏蔽循環泵
一個軟化水箱。
這些設備由一台操作站來監控。軟化水箱的超高和 超低水位、係(xi)統(tong)超(chao)溫(wen)超(chao)壓(ya)信(xin)號(hao)在(zai)操(cao)作(zuo)台(tai)產(chan)生(sheng)報(bao)警(jing)信(xin)息(xi)。操(cao)作(zuo)人(ren)員(yuan)通(tong)過(guo)監(jian)控(kong)畫(hua)麵(mian)很(hen)方(fang)便(bian)地(di)了(le)解(jie)設(she)備(bei)運(yun)行(xing)狀(zhuang)態(tai)，並(bing)可(ke)通(tong)過(guo)該(gai)畫(hua)麵(mian)手(shou)動(dong)控(kong)製(zhi)調(tiao)節(jie)設(she)備(bei)的(de)運(yun)行(xing)。重(zhong)要(yao)的(de)參(can)數(shu)可(ke)切(qie)換(huan)到(dao)曲(qu)線(xian)窗(chuang)口(kou)，便(bian)於(yu)觀(guan)察(cha)分(fen)析(xi)。
曲線監控窗口
鍋爐本身的控製台有觸摸屏和S7-200PLC；循環泵和補水泵電源來自於四台變頻器；控製室的空間狹窄， 采集係統信號的儀表櫃和 變頻器櫃的距離很小，變頻器的射頻等因素幹擾操作站的通訊是必然存在的問題。綜合考慮控製的獨立性、抗幹擾性、節能性，鍋爐采用反饋控製方式，即操作站不下發鍋爐的啟停信號，而通過輸出供暖量調節鍋爐的啟停； 供暖係統的信號由 儀表櫃中的S7-300PLC采集，上傳至操作站。用S7-300PLC采集信號和操作站通訊是為保證控製係統的穩定性，在強幹擾環境中， S7-300的抗幹擾能力遠優越於普通信號采集模塊；xunhuanbenghebushuibengdezikonggongnengyoucaozuozhanzijinqiaozutairuanjiandejiaobenchengxubianxie。yejiushibianxielianggezhinengshebeichengxu，fenbieshibianpinhengyabushuikongzhiqiheqihoubuchangqi。
