RELANCE 800756-21B 频率模块
0-57C405-C分散控制系统具备离线仿真功能，通过虚拟控制器软件，可以在任意一台PC机上同时仿真64个控制器节点，不同的PC机上的仿真控制器间可以相互通讯，同时仿真控制器也可以与真实控制器通讯，功能和网络特性与真实控制器完全一致。虚拟控制器软件具备仿真控制器工况冻结，保存，恢复（回滚）的功能，结合模型软件很容易构成虚拟DCS仿真系统。
0-57C405-C的系统机柜及其中的各个部件，全部采用模块化标准设计， 机柜内部没有任何的手工接线。这样的标准机柜能够进行工厂化生产，以保证更高质量、更短的交货时间和更低的成本。标准机柜配上不同的卡件就能够满足不同项目的需求。
支持在线组态功能，具备多人同时对同一控制器进协同组态能力，允许多人在线进行组态修改和进行控制器及无扰下装。控制器组态更新没有编译过程，新组态在一个控制周期内生效，可以随时修改随时可用，便于参数修改和多人同时进行现场调试。
在线组态模式下，修改并下装组态页面不会对系统中没有变更的组态、模块参数或控制环路造成扰动（故意打断控制逻辑回路或变更模块参数除外）。0-57C405-C分散控制系统在线下装的最小逻辑单元是一个组态页面，其中最小的组态变更范围是单个功能模块的单个参数。
In online configuration mode, modifying and uninstalling configuration pages will not cause disturbance to unchanged configurations, module parameters, or control loops in the system (except for intentionally interrupting control logic loops or changing module parameters). The minimum logical unit installed offline in the 0-57C405-Cdecentralized control system is a configuration page, where the minimum configuration change range is a single parameter of a single functional module.
Support online configuration function, with the ability for multiple people to simultaneously perform collaborative configuration on the same controller, allowing multiple people to make configuration modifications and perform controller and undisturbed installation online. The controller configuration update does not have a compilation process. The new configuration takes effect within one control cycle and can be modified at any time, making it convenient for parameter modification and on-site debugging by multiple people simultaneously.
In the application and development process of DCS, there are frequent changes in system configuration and functional requirements, and each change will cause corresponding changes in DCS configuration and engineering data. In generally mature DCS, the configuration function is relatively strong. Adding a card, modifying a logic, and adjusting a screen often takes a few minutes, while modifying relevant engineering data takes several hours. The automatic maintenance function of engineering data is provided in NT6000, freeing engineers from tedious data organization work. The system can ensure the accuracy of generated logic diagrams and IO inventory, providing a powerful tool for data archiving and communication, making the development and maintenance of DCS twice the result with half the effort.
