ArchestrA Technology Simplifies Device IntegrationLAKE FOREST, March 12, 2004 -- Wonderware, a business unit of Invensys Systems, Inc., today introduced a new DA Server called SI Direct. SI Direct is designed to replace Siemens(TM) Simatic(R) Net middleware to connect to PLCs in the Siemens S7 family. In addition to the DAServer, ArchestrA Device Integration (DI) Objects have been created to represent the device and network hierarchy when connecting Siemens S7 PLCs to the Industrial Application Server. Wonderware's DA Servers are built using the ArchestrA DAS toolkit and offer enhanced communication diagnostics and performance. DA Servers are Wonderware's next-generation I/O servers and a significant part of Wonderware's FactorySuite A2 ("A-squared") product line. The "A2" signifies the presence of ArchestrA technology. "Leveraging the power of ArchestrA technology and the DI Object functionality, it is now possible to model a Siemens PLC as part of a FactorySuite A2 application," said Tom Muth, Wonderware's FactorySuite A2 product marketing manager. "This new DA Server builds upon Wonderware's ability to provide tighter integration with controllers, reducing the amount of configuration necessary for device communications."Wonderware's SI Direct DA Server provides access to data within the Siemens S7 200/300/400 family of PLCs through an off-the-shelf standard Ethernet network interface card. The DI Objects represent the network as well as the PLCs, providing the user with a hierarchical view of their connectivity. When used in conjunction with Wonderware's Industrial Application Server, the DI Objects allow users or systems integrators to configure, deploy and monitor servers from one centralized location known as the Integrated Development Environment (IDE). Because the IDE centralizes all systems and applications, users simply have to install the software on the Industrial Application Server once, rather than installing the software on multiple separate computers. It also allows for online configuration and diagnostic capabilities.When operated as a stand-alone server, the SI Direct DA Server enables the user to start, stop, configure and monitor communications between the client and device using a single utility. Each server built with the toolkit provides the ability to access a rich set of diagnostics during runtime. In addition, the framework offers sorting capabilities, optimizes communications and supports the OPC 2.05 standard.With a single development effort, every DA Server provides connectivity between client applications based on Wonderware's SuiteLink protocol and OPC(R) and DDE protocols running on the Microsoft(R) Windows(R) 2000 and Microsoft XP(TM) operating systems, as well as data devices supported by the specific translated protocol.Wonderware's SI Direct DA Servers work with all FactorySuite A2 products, such as the Industrial Application Server, InTouch visualization software, InTrack resource tracking software and InBatch production management software.About Invensys' Wonderware and ArchestrA Business Units Wonderware and ArchestrA are business units of Invensys Systems, Inc.
