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).
