              DCS組態的步驟有哪些?

              01前期準備工作
              01 preliminary preparation
              進入系統組態前,應首先確定測點清單、控制運算方案、系統硬件配置,包括系統的規模、各站IO單元的配置及測點的分配等,還要提出對流程圖、報表、歷史數據庫、追憶庫等的設計要求。
              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建立目標工程
              02 establish target project
              在正式進行應用工程的組態前,必須針對該應用工程定義一個工程名,該目標過程建立后,便建立起了該工程的數據目錄。
              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系統組態設備
              03 system configuration equipment
              應用系統的硬件配置通過系統配置組態軟件完成。采用圖形方式,系統網絡上連接的每一種設備都與一種基本圖形對應。在進行系統設備組態之前必須在數據庫總控中創建相應的工程。
              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數據庫組態
              04 database configuration

              數據庫組態就是定義和編輯系統各站的點信息,這是形成整個應用系統的基礎。在MACS系統中有兩類點,一類是實際的物理測點,存在于現場控制站和通信站中,點中包含了測點類型、物理地址、信號處理和顯示方式等信息;一類是虛擬量點,同實際物理測點相比,差別僅在于沒有與物理位置相關的信息,可在控制算法組態和圖形組態中使用。
              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控制算法組態
              05 control algorithm configuration
              在完成數據庫組態后就可以進行控制算法組態。dcs系統提供了符合IEC1131-3標準的五種工具: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圖形、報表組態
              06 graphic and report configuration
              圖形組態包括背景圖定義和動態點定義,其中動態點動態顯示其實時值或歷史變化情況,因而要求動態點必須同已定義點相對應。通過把圖形文件連入系統,就可實現圖形的顯示和切換。
              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編譯生成
              07 compilation generation
              系統聯編功能連接形成系統庫,成為操作員站、現場控制站上的在線運行軟件的基礎。系統包括實時庫和參數庫兩個部分組成,系統把所有點中變化的數據項放在實時庫中,而把所有點中不經常變化的數據項放在參數庫中。服務器包含了所有的數據庫信息,而把現場控制站上只包含該站相關的點和方案頁信息,這是在系統生成后由系統管理中的下裝功能自動完成的。
              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系統下裝
              08 system lower installation
              應用系統生成完畢后,應用系統的系統庫、圖形和報表文件通過網絡下裝在服務器和操作員站。服務器到現場控制站的下裝是在現場控制站啟動時自動進行的?,F場控制站啟動時如果發現本地的數據庫版本號與服務器不一致,便會向服務器請求下裝數據庫和方案頁。
              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.
