01 preliminary preparation
Before entering the system configuration, first determine the list of measuring points, control operation scheme and system hardware configuration, including the scale of the system, the configuration of IO units of each station and the distribution of measuring points, and put forward the design requirements for flow chart, report, historical database and memory database.
02 establish target project
Before the formal configuration of the application project, a project name must be defined for the application project. After the target process is established, the data directory of the project is established.
03 system configuration equipment
The hardware configuration of the application system is completed by the system configuration software. In the form of graphics, each device connected to the system network corresponds to a basic graphics. Before system equipment configuration, corresponding projects must be created in the database master control.
04 database configuration
Database configuration is to define and edit the point information of each station of the system, which is the basis of the whole application system. There are two types of points in MACS system. One is the actual physical measuring point, which exists in the field control station and communication station. The point contains the information such as measuring point type, physical address, signal processing and display mode; One is the virtual measuring point. Compared with the actual physical measuring point, the difference is that there is no information related to the physical position, which can be used in the control algorithm configuration and graphic configuration.
05 control algorithm configuration
After completing the database configuration, the control algorithm can be configured. DCS system provides five tools conforming to iec1131-3 standard: SFC, St, FBD, LD and FM.
06 graphic and report configuration
Graphic configuration includes background map definition and dynamic point definition, in which the dynamic point dynamically displays the real-time value or historical change, so it is required that the dynamic point must correspond to the defined point. By connecting the graphic files into the system, the display and switching of graphics can be realized.
07 compilation generation
The system linkage function is connected to form a system library, which becomes the basis of online operation software on operator station and field control station. The system consists of real-time database and parameter database. The system puts the data items that change in all points in the real-time database, and the data items that do not change frequently in all points in the parameter database. The server contains all database information, while the field control station only contains the relevant point and scheme page information of the station, which is automatically completed by the download function in the system management after the system is generated.
08 system lower installation
After the application system is generated, the system library, graphics and report files of the application system are installed in the server and operator station through the network. The downloading from the server to the field control station is automatically carried out when the field control station is started. When the field control station is started, if it is found that the local database version number is inconsistent with the server, it will request the server to download the database and scheme page.
