RELANCE 800756-21B 频率模块
0-57C404-1E支持SAMA图标准组态逻辑，复杂的顺序控制和回路控制都可以用直观易学的模块化组态方式来实现。IO组态支持Excel文件导入导出，简化IO组态操作，所有图形化组态页面可以导出为PDF文档或SVG矢量图形文件，便于工程资料维护存档、二次处理和外部交流。
在DCS的应用和开发过程中，经常性的会出现系统配置和功能要求的变更，每一个变更都会引起DCS组态、工程资料的相应变化。一般成熟的DCS中，组态功能都比较强，增加一块卡件，修改一个逻辑，调整一个画面，往往是几分钟的时间，而修改相关的工程资料则需要几个小时。在0-57C404-1E中提供工程资料的自动维护功能，将工程师从烦琐的资料整理工作中解放出来，系统能够保证生成的逻辑图和IO清册的准确性，为资料的存档和交流工作提供了强有力的工具，使DCS的开发维护工作事半功倍。
0-57C404-1E的历史数据功能采用客户/服务器的结构来完成，设计开发了功能强大的高性能历史数据库，数据记录精度可以达到1ms，容量达到10万点。
在每个操作员站中通过历史数据客户端可以快速方便地调出历史数据服务器存储的所有数据，即使是长达数月的历史数据，都能够在1秒左右的时间内调出。0-57C404-1E的历史数据客户端功能丰富，使用灵活，为操作员提供有效的数据分析手段。解决了传统DCS中，历史数据功能只能提供给工程师站或少数客户端使用，调用数据慢，用户界面复杂的问题。改变了历史数据不能被普通操作员掌握和使用的局面，为操作员更好的使用历史数据进行过程分析、提高运行水平提供了技术基础。
The 0-57C404-1Esupports SAMA diagram standard configuration logic, and complex sequential control and loop control can be achieved through intuitive and easy to learn modular configuration methods. IO configuration supports Excel file import and export, simplifying IO configuration operations. All graphical configuration pages can be exported as PDF documents or SVG vector graphics files, making it easy to maintain and archive engineering data, secondary processing, and external communication.
The historical data function of NT6000 is completed using a client/server structure, and a powerful high-performance historical database has been designed and developed. The data recording accuracy can reach 1ms, and the capacity can reach 100000 points.
In each operator station, all data stored on the historical data server can be quickly and conveniently retrieved through the historical data client. Even months of historical data can be retrieved in about 1 second. The historical data client of NT6000 has rich functions and flexible usage, providing operators with effective data analysis methods. Solved the problem of slow data retrieval and complex user interface in traditional DCS, where the historical data function can only be provided to engineer stations or a few clients. This has changed the situation where historical data cannot be mastered and used by ordinary operators, providing a technical foundation for operators to better use historical data for process analysis and improve operational level.
For users, they can directly use all data from the KM950 controller without worrying about data processing processes such as network protocol and interface program redundancy verification and compression. The network protocol and interface program do not require any setup work and are completely transparent and easy to understand. The process of configuring or modifying the KM950 controller is the process of establishing and modifying the distributed real-time process control database. Distributed transparent databases only rely on the KM950 controller and are directly transmitted to the operating station through the network without any intermediate links. The reliability and transmission speed of data communication are superior to DCS with server structure
