1. System Architecture

As shown in the above figure, the dotted box is the whole control system, which mainly includes three major parts, namely, controller (PLC), operator and engineer station. The controller communicates with the field instrumentation through Ethernet and ProfiBus DP or other communication methods, and the operator station and engineer station communicate with the controller through Ethernet. According to the size of the project, different numbers of operator stations can be configured to meet the needs of actual engineering applications.

2. Main Functions of the Controller

◆ Use signals from field instruments (pulses, 4 to 20mA, 0 to 10V, temperature and other signals);

◆ Perform all control operations;

◆ Output execution signals based on the calculation result;

◆ Complete data communication tasks;

◆ Provides the operator station with information on the completion of processing.

Main Functions of the Engineer Station

◆ Complete the configuration of the entire system;

◆ Configure the database and reports;

◆ Make changes to the entire system.

Main Functions of the Operator Station

◆ Manage and monitor the production site;

◆ Perform centralized management and monitoring of system data;

◆ Display process flow diagrams;

◆ Print statement;

◆ Make changes to various process parameters.

Typical interfaces that can be seen at the operator station are the state of control system, production process flow diagrams, various production statements, real-time and historical trends, etc.
