DAServer的产品概念

DAServer是采用Wonderware公司 ArchestrA™ 技术构建的新一代服务器组件。ArchestrA体系可以延长现有系统的寿命，提供更高效使用现有模板的方法以及最好的搭建新体系的理论。

在早期的工业软件中，任务栏中运行着各种复杂而繁琐的软件，各种名为I/Oserver,InTouch,InSQL,WWLOGGER的产品和组件都是作为单独的个体而独立的存在着，并且这些软件都缺乏图形界面和用户操作体验。后来，这样的问题都不见了，2003年在FactorySuite出现的ArchestrA技术使一切得到了重生，产品之间再没有“共享标签信息”的概念，取而代之的是在每个产品必须有相同的注册标签，用“新一代”的词汇来形容这项工业软件技术是再准确不过了。

ArchestrA技术运用在一个联合的平台上，这样的平台运行着诸如DAServer, WWLOGGER, InSQL SMC这样的程序组件。由于SMC提供图形用户界面，windows的MMC提供管理控制平台，即使是一堆有通讯驱动的不同种机器设备，有意识的使用相同的搭建方式达到管控的目的都是有可能实现的。

DAServer是什么

OPC工业标准是有别于过去I/O服务器支持的DDE/SuiteLink协议，为满足工业通讯需求设定的标准，DAServer的设计就是与这项标准保持一致。它让这些协议以插件的形式安装，并以动态的形式运行着。通过使用DAServer将服务器的设置和诊断通信信息等构建进ArchestrA体系，以达到创建无缝系统的目的。

DAServer的体系结构

DAServer是没有图形用户界面的应用程序。那些诸如设置和诊断的图形界面是通过SMC来提供的，并且SMC还能够监控浏览和实时通信状态记录等标记信息。此外，由于定义和设置等信息是以XML形式处理的，这些都可以用激活了防火墙的远程计算机和创建另外一个节点访问服务器来完成。

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.
