RELANCE 800756-21B 頻率模塊
800756-21B 虛擬系統(tǒng)。在虛擬化系統(tǒng)解決了冗余容錯問題之后，Honeywell、ABB等DCS行業(yè)巨頭近年來紛紛開始采用這一技術。在全球過程控制領域中，虛擬化也已成為普遍接受的行業(yè)準則。它能夠簡化冗余，加快系統(tǒng)集成的速度。虛擬化的另一個明顯優(yōu)勢是極大節(jié)省了服務器的硬件數量和采購費用，把過去很多服務器分擔的工作安裝在同一個虛擬化系統(tǒng)中。
800756-21B 組態(tài)靈活。相較于PLC，DCS是更為龐大復雜的體系。DCS經四代技術變革，核心始終是借助于先進的計算機技術、通訊技術和控制技術等不斷優(yōu)化，以實現分散控制、集中操作、分級管理、配置靈活和組態(tài)方便等。如800756-21B，簡化了系統(tǒng)下載過程，并支持同一 OS 項目的工藝流程圖多用戶組態(tài)。新版的800756-21B組態(tài)更為靈活，可并行組態(tài)，最大程度縮減工程時間成本。
高度集成。這一點毋庸置疑，隨著工廠智能化需求的進一步提高，越來越多的設備和系統(tǒng)需要被集成進控制系統(tǒng)。如ABB最新的800xA系統(tǒng)除了集成報警管理、先進控制、視頻系統(tǒng)、安全和其它內置功能外，還擴展到了電氣集成。而羅克韋自動化最新的PlantPAx則集成了電機控制功能。
信息安全。工控系統(tǒng)面臨的安全形勢日益嚴峻，DCS供應商也在此下足了功夫。如ABB 800xA v6版，進一步提升了工業(yè)控制系統(tǒng)信息安全性能，如訪問控制或白名單、監(jiān)控和管理過程系統(tǒng)的安全等等，通過數據的無縫訪問來提高生產力、效率和安全水平。
Flexible configuration. Compared to PLC, DCS is a larger and more complex system. Through four generations of technological transformation, DCS has always relied on advanced computer technology, communication technology, and control technology to continuously optimize and achieve decentralized control, centralized operation, hierarchical management, flexible configuration, and convenient configuration. Like Siemens SIMATIC PCS 7 V8.1, it simplifies the system download process and supports multi-user configuration of process flowcharts for the same OS project. The new SIMATIC PCS 7 V8.1 configuration is more flexible and can be configured in parallel, minimizing engineering time and costs.
Virtual system. After virtualization systems have solved the problem of redundant error tolerance, DCS industry giants such as Honeywell and ABB have begun to adopt this technology in recent years. In the field of global process control, virtualization has also become a widely accepted industry norm. It can simplify redundancy and accelerate system integration speed. Another obvious advantage of virtualization is that it greatly saves the hardware quantity and procurement costs of servers, installing the work that many servers shared in the past into the same virtualization system.
Highly integrated. There is no doubt about this, as the demand for factory intelligence continues to increase, more and more equipment and systems need to be integrated into control systems. ABB's latest 800xA system not only integrates alarm management, advanced control, video system, security, and other built-in functions, but also extends to electrical integration. And Rockwell Automation's latest PlantPAx integrates motor control functions.
Information security. The safety situation faced by industrial control systems is becoming increasingly severe, and DCS suppliers have also made great efforts in this regard. The ABB 800xA v6 version further enhances the information security performance of industrial control systems, such as access control or whitelist, monitoring and management process system security, etc. Through seamless data access, productivity, efficiency, and security levels are improved.
