FCS、Siemens S7以及煉鋼生產(chǎn)網(wǎng)絡(luò)配置圖
現(xiàn)場總線是將自動化zui底層的現(xiàn)場控制器和現(xiàn)場智能儀表設(shè)備互連的實(shí)時控制通訊網(wǎng)絡(luò),遵循ISO的OSI開放系統(tǒng)互連參考模型的全部或部分通訊協(xié)議。FCS現(xiàn)場控制系統(tǒng)則把單個分散的測量控制設(shè)備變成網(wǎng)絡(luò)節(jié)點(diǎn),共同完成自控任務(wù)的網(wǎng)絡(luò)系統(tǒng)與控制系統(tǒng),所以說現(xiàn)場總線既是通信網(wǎng)絡(luò),又是自控系統(tǒng)。煉鋼廠以典型總線類型西門子Profibus-DP作為生產(chǎn)網(wǎng)。其數(shù)據(jù)傳輸類型是RS485傳輸,支持9.6K~12M的通信速率和中繼器(REPEATER)的擴(kuò)展功能,支持基于光纖傳輸介質(zhì)的通信;也支持點(diǎn)對點(diǎn)、總線及環(huán)形光纖網(wǎng)??刂破骺膳渲贸呻p機(jī)熱備及冗余通信模式,用于對可靠性要求很高的場合, 控制器或主站控制器基于通用工業(yè)PC機(jī)、Windows NT軟硬件平臺??偩€接口一般采用PCI總線的PROFIBUS網(wǎng)卡(如CP1613)。煉鋼廠只以1.5MDP的通訊速率、光纖傳輸介質(zhì)Repeater擴(kuò)展、雙機(jī)熱備、總線鏈路而形成生產(chǎn)網(wǎng),如圖3。
Profibus-DP主要用于工業(yè)自動化系統(tǒng)的高速數(shù)據(jù)傳送,實(shí)現(xiàn)調(diào)節(jié)和控制功能,是一種高速低成本通訊,用于設(shè)備級控制系統(tǒng)與分散式I/O的通訊;CP443-1是以TCP/IP協(xié)議進(jìn)行通訊,下掛EWS工程師站、服務(wù)器等等,CP443-5則是以PROFIBUS協(xié)議下掛VVVF、ET200等工控產(chǎn)品,其網(wǎng)絡(luò)簡單,容易維護(hù);由于輸入、輸出模件ET200是總線傳輸形式,安在現(xiàn)場的節(jié)點(diǎn),節(jié)省了大量的信號線纜,這也正是有別于DCS的zui大優(yōu)勢所在。
煉鋼廠2號連鑄主系統(tǒng)使用6個PLC處理器,雙服務(wù)器熱備,其中VVVF擁有兩條總線,用于與PLC信息通訊和專機(jī)讀取、下裝變頻參數(shù).
