What is DAServer?
Concept of DAServer
The DAServer is designed based on architecture "ArchestrA" of the next generation industrial software of the Wonderware. ArchestrA : an architecture which is 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 were 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 must register same tag in each product, it is now suitable to call "Next generation" industrial software.
In FactorySuite ArchestrA, it operates on the union platform that is called each function components such as DAServer, WWLOGGER, and InSQL SMC. Because SMC offers GUI and the operability by using MMC of Windows, it can put into the plant by the same operability not aware of communication driver even if various field equipment exist in user’s plant.
DAServer corresponds to OPC: A standard specification of communication between applications in 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 plug-in, and executed dynamically. The server setting and communication diagnosis information, etc. are built into ArchestrA by using a 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 diagnosis screens are offered through SMC, and can monitor the browsing on tag information and communication status information etc. in real time. Moreover, definition information and the set up information, etc. are processed by the XML form, so an access to the server installed in another node and a remote computing through the firewall are enabled.
