RELANCE 800756-21B 频率模块
800756-21B 虚拟系统。在虚拟化系统解决了冗余容错问题之后，Honeywell、ABB等DCS行业巨头近年来纷纷开始采用这一技术。在全球过程控制领域中，虚拟化也已成为普遍接受的行业准则。它能够简化冗余，加快系统集成的速度。虚拟化的另一个明显优势是极大节省了服务器的硬件数量和采购费用，把过去很多服务器分担的工作安装在同一个虚拟化系统中。
800756-21B 组态灵活。相较于PLC，DCS是更为庞大复杂的体系。DCS经四代技术变革，核心始终是借助于先进的计算机技术、通讯技术和控制技术等不断优化，以实现分散控制、集中操作、分级管理、配置灵活和组态方便等。如800756-21B，简化了系统下载过程，并支持同一 OS 项目的工艺流程图多用户组态。新版的800756-21B组态更为灵活，可并行组态，最大程度缩减工程时间成本。
高度集成。这一点毋庸置疑，随着工厂智能化需求的进一步提高，越来越多的设备和系统需要被集成进控制系统。如ABB最新的800xA系统除了集成报警管理、先进控制、视频系统、安全和其它内置功能外，还扩展到了电气集成。而罗克韦自动化最新的PlantPAx则集成了电机控制功能。
信息安全。工控系统面临的安全形势日益严峻，DCS供应商也在此下足了功夫。如ABB 800xA v6版，进一步提升了工业控制系统信息安全性能，如访问控制或白名单、监控和管理过程系统的安全等等，通过数据的无缝访问来提高生产力、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.
