01前期准备工作
01 preliminary preparation
进入系统组态前,应首先确定测点清单、控制运算方案、系统硬件配置,包括系统的规模、各站IO单元的配置及测点的分配等,还要提出对流程图、报表、历史数据库、追忆库等的设计要求。
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建立目标工程
02 establish target project
在正式进行应用工程的组态前,必须针对该应用工程定义一个工程名,该目标过程建立后,便建立起了该工程的数据目录。
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系统组态设备
03 system configuration equipment
应用系统的硬件配置通过系统配置组态软件完成。采用图形方式,系统网络上连接的每一种设备都与一种基本图形对应。在进行系统设备组态之前必须在数据库总控中创建相应的工程。
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数据库组态

数据库组态就是定义和编辑系统各站的点信息,这是形成整个应用系统的基础。在MACS系统中有两类点,一类是实际的物理测点,存在于现场控制站和通信站中,点中包含了测点类型、物理地址、信号处理和显示方式等信息;一类是虚拟量点,同实际物理测点相比,差别仅在于没有与物理位置相关的信息,可在控制算法组态和图形组态中使用。
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控制算法组态
05 control algorithm configuration
在完成数据库组态后就可以进行控制算法组态。dcs系统提供了符合IEC1131-3标准的五种工具:SFC、ST、FBD、LD和FM。
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图形、报表组态
06 graphic and report configuration
图形组态包括背景图定义和动态点定义,其中动态点动态显示其实时值或历史变化情况,因而要求动态点必须同已定义点相对应。通过把图形文件连入系统,就可实现图形的显示和切换。
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编译生成
07 compilation generation
系统联编功能连接形成系统库,成为操作员站、现场控制站上的在线运行软件的基础。系统包括实时库和参数库两个部分组成,系统把所有点中变化的数据项放在实时库中,而把所有点中不经常变化的数据项放在参数库中。服务器包含了所有的数据库信息,而把现场控制站上只包含该站相关的点和方案页信息,这是在系统生成后由系统管理中的下装功能自动完成的。
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系统下装
08 system lower installation
应用系统生成完毕后,应用系统的系统库、图形和报表文件通过网络下装在服务器和操作员站。服务器到现场控制站的下装是在现场控制站启动时自动进行的。现场控制站启动时如果发现本地的数据库版本号与服务器不一致,便会向服务器请求下装数据库和方案页。
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.
