(2) Real time database generation

The real-time database is the most basic information resource of DCS, and these real-time data are stored and managed by the real-time database.

In DCS, there are various methods for establishing and modifying real-time database records. The commonly used method is to use general database tool software to generate database files, and the system directly uses this data format for management or uses some method to convert the generated data files into the format required by DCS.

Generation of Industrial Process Screens

DCS is a comprehensive control system that must have rich control and detection system screen display functions. Obviously, different control systems require different screens to be displayed. Overall, it is a basic requirement for DCS configuration to represent various measurement and control parameters and system status in appropriate forms such as characters, bar charts, curves, etc., combined with the overall appearance, grouping, control circuit, flowchart, alarm, etc.
