DAServer的產品概念

DAServer是采用Wonderware公司 ArchestrA™ 技術構建的新一代服務器組件。ArchestrA體系可以延長現有系統的壽命，提供更高效使用現有模板的方法以及最好的搭建新體系的理論。

在早期的工業軟件中，任務欄中運行著各種復雜而繁瑣的軟件，各種名為I/Oserver,InTouch,InSQL,WWLOGGER的產品和組件都是作為單獨的個體而獨立的存在著，并且這些軟件都缺乏圖形界面和用戶操作體驗。后來，這樣的問題都不見了，2003年在FactorySuite出現的ArchestrA技術使一切得到了重生，產品之間再沒有“共享標簽信息”的概念，取而代之的是在每個產品必須有相同的注冊標簽，用“新一代”的詞匯來形容這項工業軟件技術是再準確不過了。

ArchestrA技術運用在一個聯合的平臺上，這樣的平臺運行著諸如DAServer, WWLOGGER, InSQL SMC這樣的程序組件。由于SMC提供圖形用戶界面，windows的MMC提供管理控制平臺，即使是一堆有通訊驅動的不同種機器設備，有意識的使用相同的搭建方式達到管控的目的都是有可能實現的。

DAServer是什么

OPC工業標準是有別于過去I/O服務器支持的DDE/SuiteLink協議，為滿足工業通訊需求設定的標準，DAServer的設計就是與這項標準保持一致。它讓這些協議以插件的形式安裝，并以動態的形式運行著。通過使用DAServer將服務器的設置和診斷通信信息等構建進ArchestrA體系，以達到創建無縫系統的目的。

DAServer的體系結構

DAServer是沒有圖形用戶界面的應用程序。那些諸如設置和診斷的圖形界面是通過SMC來提供的，并且SMC還能夠監控瀏覽和實時通信狀態記錄等標記信息。此外，由于定義和設置等信息是以XML形式處理的，這些都可以用激活了防火墻的遠程計算機和創建另外一個節點訪問服務器來完成。

Product concept of DAServer

The DAServer is designed based on architecture "ArchestrA" of the next generation industrial software of the Wonderware. ArchestrA * architecture is architecture that can be developed to extend the longevity of an existing system, and achieve a method of operating an existing plant more efficiently and the best method of constructing a new plant mutually.

Many applications were complexly displayed in the taskbar as for a past factory package software group because software product/component named the I/O server, InTouch, InSQL, and WWLOGGER operated respectively as an individual application, and the commonness of GUI and the operation was scarce in each product. Moreover, all these problems were canceled, and FactorySuite ArchestrA that had appeared in 2003 was reborn though there was no concept "Shared of tag information" between products but there was a case to have to register tag the same in each product, too as industrial software suitable for calling exactly, "Next generation". 

In FactorySuite ArchestrA, it operates on the union platform that is called each function components such as the DAServer, WWLOGGER, and InSQL SMC. Because SMC offers GUI and the operativeness united by using MMC of Windows, putting in to the plant by the same operativeness consciously even if the user is a plant where various field equipment exist of the communication driver becomes possible.

What's DAServer

The DAServer corresponds to OPC that is a standard specification of interapplication communications of the industrial world in addition to the DDE/SuiteLink protocol supported by a past I/O server. These protocols are mounted in the form of the plug-in, and executed dynamically. The server setting and communication diagnosis information, etc. are built into ArchestrA by using the DAServer, and seamless system construction is achieved.

Architecture of DAServer

DAServer operates as an application without GUI. The GUI services such as set screens and the diagnosis screens are offered through SMC, and can monitor the browsing and communication status information etc. on tag information in real time. Moreover, because definition information and the set up information, etc. are processed by the XML form, an access to the server installed in another node and a remote computing through the firewall are enabled.
