Honeywell FC-PSU-UNI2450U V1.0 DCS系统备件

Honeywell FC-PSU-UNI2450U V1.0DCS系统中，控制站作为一个完整的计算机，它的主要I/O设备为现场的输入、输出处理设备，以及过程输入/输出（PI/O），包括信号变换与信号调理，A/D、D/A转换。控制站是整个DCS的基础，它的可靠性和安全性最为重要，死机和控制失灵的现象是绝对不允许的，而且冗余、掉电保护、抗干扰、构成防爆系统等方面都应很有效而可靠，才能满足用户要求。

关于Honeywell FC-PSU-UNI2450U V1.0DCS控制站的系统软件，包括实时操作系统、编程语言及编译系统、数据库系统、自诊断系统等，只是完善程度不同而已。第二代DCS控制站开始有面向过程语言和高级语言；第三代DCS控制站的系统软件可以完成离线组态及在线修改控制策略。为了完成控制策略，对于顺序控制和批量控制组态编程，各种DCS控制站采用不同的方法。

Honeywell FC-PSU-UNI2450U V1.0DCS操作站具有操作员功能、工程师功能、通信功能和高级语言功能等，其中工程师功能中包括系统组态、系统维护、系统通用（Utility）功能，还有系统配置、操作标记、趋势记录、历史数据管理、总貌画面组态、控制站组态、工艺单元或区域组态等。

实际的Honeywell FC-PSU-UNI2450U V1.0DCS操作站是典型的计算机，它与控制站不同，有着丰富的外围设备和人机界面。在人机界面方面，逐渐过渡为以GUI图形用户界面为平台并采用鼠标，组态时制作流程图和控制回路图等采用菜单、窗口等，使人机界面友好。第三代DCS操作站是在个人计算机（PC）及Windows操作系统普及和通用监控图形软件已商品化的基础上诞生的。DDE或OPC接口技术，以太网接口与管理网络相连。DCS系统组态、操作站组态、控制站组态均有相应软件，为DCS用户的工程设计人员提供人机界面。有的DCS的采用通用监控图形软件，或以此类软件为核心，进行二次开发。

因为数据通信标准牵涉到网络结构、通信介质（信道）、通信协议、IEEE802.4令牌总线传输方式和IEEE802.5令牌环网传输方式的通信协议在DCS系统中应用最广，是否能够成为今后DCS的通讯标准，还有待观察。

In Honeywell FC-PSU-UNI2450Uv1.0 DCS system, the control station is a complete computer, and its main I/O devices are on-site input and output processing devices and process input/output (PI/O), including signal transformation and signal conditioning, A/D and D/A conversion. The control station is the foundation of the whole DCS, and its reliability and safety are the most important. The phenomenon of crash and control failure is absolutely not allowed, and redundancy, power failure protection, anti-interference and explosion-proof system should be effective and reliable to meet the requirements of users.

The system software of Honeywell FC-PSU-UNI2450Uv1.0 DCS control station includes real-time operating system, programming language and compiling system, database system, self-diagnosis system, etc., but the degree of perfection is different. The second generation DCS control station began to have process-oriented language and high-level language; The system software of the third generation DCS control station can complete offline configuration and online modification of control strategy. In order to complete the control strategy, various DCS control stations adopt different methods for sequential control and batch control configuration programming.

Honeywell FC-PSU-UNI 2450U V1.0DCS operating station has the functions of operator, engineer, communication and advanced language, among which the functions of engineer include system configuration, system maintenance and system Utility, as well as system configuration, operation marking, trend recording, historical data management, general picture configuration, control station configuration, process unit or area configuration, etc.

The actual Honeywell FC-PSU-UNI2450U V1.0DCS operating station is a typical computer, which is different from the control station and has rich peripheral equipment and man-machine interface. In the aspect of man-machine interface, the GUI graphical user interface is gradually transformed into the platform and the mouse is used. When configuring, menus and windows are used to make the flow chart and control loop diagram, which makes the man-machine interface friendly. The third generation DCS operating station was born on the basis of the popularization of personal computer (PC) and Windows operating system and the commercialization of general monitoring graphic software. DDE or OPC interface technology, Ethernet interface is connected with management network. DCS system configuration, operation station configuration and control station configuration all have corresponding software to provide man-machine interface for engineering designers of DCS users. Some DCS adopt general monitoring graphic software, or take this kind of software as the core to carry out secondary development.

Because the data communication standard involves network structure, communication medium (channel), communication protocol, IEEE802.4 token bus transmission mode and IEEE802.5 token ring network transmission mode, the communication protocol is most widely used in DCS system, and it remains to be seen whether it can become the communication standard of DCS in the future.
