WOODWARD 8701-758伺服調(diào)速器,8701-758參數(shù)說明
ECS-700系統(tǒng)還基于IEC62443-1-1的工業(yè)網(wǎng)絡模型,針對LEVEL~4不同層次設計了不同的防病毒方案,聯(lián)合國際知名的防毒軟件公司,結(jié)合私有協(xié)議、白名單、WOODWARD 8701-758黑名單等綜合防毒技術(shù),為各種項目應用量身定制防毒方案,方便用戶高效地實現(xiàn)全網(wǎng)絡的安全保護和監(jiān)控。
(1)LEVEL 1層次
中控提供的控制器內(nèi)置網(wǎng)絡防火墻和協(xié)議解析、接入設備論證,控制器具有一定的防病毒能力,提高了該層次網(wǎng)絡的安全性。
(2)LEVEL 2層次
(3)LEVEL 3層次及以上
該層次計算機數(shù)量相對比較少,軟件選擇自由度較大,也可能會頻繁更換。而且L3層的各類主機不直接參與生產(chǎn)運行和控制,CPU負荷安全要求不高。因此,在L3層中控采用了殺毒性能強勁的知名殺毒軟件———卡巴斯基。
(4)調(diào)度層與控制層
通過防火墻隔離,保證控制層安全。
(5)外部網(wǎng)絡與調(diào)度層WOODWARD 8701-758伺服調(diào)速器,8701-758參數(shù)說明
通過防火墻隔離,保證調(diào)度層安全。石油、化工等流程工業(yè)是國民經(jīng)濟的支柱產(chǎn)業(yè),具有流程復雜、高溫、高壓、易燃、易爆、高危的特點,規(guī)模、能耗巨大。百萬噸級烯烴更是代表石化行業(yè)技術(shù)壁壘最高的裝置之一,其先進控制的成功實踐,代表著流程工業(yè)智能制造技術(shù)和模式發(fā)展的頂級水平。
通過核心主控裝備和軟件系統(tǒng)的國產(chǎn)化,實現(xiàn)乙烯、丙烯等石化生產(chǎn)過程的優(yōu)化控制和精細化管理,助力單元技術(shù)和集成創(chuàng)新技術(shù)的突破,完成烯烴聯(lián)合裝置從原料到產(chǎn)品,從生產(chǎn)控制到經(jīng)營決策等多層次、多視角、全方面的智能化管控,幫助傳統(tǒng)產(chǎn)業(yè)實現(xiàn)提質(zhì)降本、節(jié)能減排等可持續(xù)發(fā)展目標。
Software scheme based on PC control. In terms of PC, the main solution is realized by using real-time operating system (RTOS), such as VX works from WinDriver company in the United States. The real-time operating system can control all levels of the system, from the I / O read-write rate to the priority of each thread on the controller. In order to make it easier for users to develop reliable control programs, manufacturers have added abstraction layer and I / O read-write architecture. Therefore, this flexible software is very suitable for customized control, data recording and communication applications.
Hardware solutions mainly rely on advanced CPU technology and open design (such as industrial Ethernet). According to Moore's law, the latest CPU has stronger data processing capacity in the case of smaller volume and lower power consumption. Thus, users can not only obtain a more stable and reliable CPU, but also obtain outstanding computing
