3401  TRICONEX 控制器卡件

3401  TRICONEX 控制器卡件主要负责对域内系统数据的集中管理和监视，包括报警、日志、事故追忆等事件的捕捉和记录管理，并为域内其它各站的数据请求（包括实时数据、事件信息和历史记录）提供服务和为其它域的数据请求提供服务。运行系统以系统服务器为中心，完成所有功能。系统服务器还提供二次数据处理和历史数据管理和存档功能。

3401  TRICONEX 控制器卡件是DCS系统实现数据采集和过程控制的重要站点，主要完成数据采集、工程单位变换、控制算法处理、输出控制、通过系统网络将数据和诊断结果传送到系统服务器等功能。

3401 TRICONEX controller card is mainly responsible for the centralized management and monitoring of system data in the domain, including the capture and record management of alarms, logs, accident recall and other events, and provides services for data requests (including real-time data, event information and history records) of other stations in the domain and provides services for data requests in other domains. The running system takes the system server as the center to complete all functions. The system server also provides secondary data processing and historical data management and archiving functions.

3401 TRICONEX controller card is an important site for DCS system to achieve data acquisition and process control, mainly to complete data acquisition, engineering unit transformation, control algorithm processing, output control, data and diagnostic results transmitted to the system server through the system network.

The 3401 TRICONEX controller card consists of a main control unit, an intelligent I/O unit, a power supply unit and a dedicated cabinet. On the main control unit and intelligent I/O unit, the real-time control software and I/O unit operation software are cured respectively. The field control station adopts the distributed structure, and the main control unit of the field control station is connected with the system network, which can be configured redundantly. The main control unit is connected to each intelligent I/O unit via a control network (CNET).
