The system server 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 memories and other events, and provides services for data requests of other stations in the domain (including real-time data, event information and historical records) and for data requests of other domains. The running system takes the system server as the center and completes all functions. The system server also provides secondary data processing and historical data management and archiving functions.

The field control station is an important station for DCS system to realize data acquisition and process control, which mainly completes the functions of data acquisition, engineering unit transformation, control algorithm processing, output control, and transmitting data and diagnosis results to the system server through the system network. The field control station consists of four parts: main control unit, intelligent I/O unit, power supply unit and special cabinet. On the main control unit and intelligent I/O unit, real-time control software and I/O unit running software are solidified respectively. The field control station adopts a 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 with each intelligent I/O unit through a control network (CNET).
