Widespread Customer Adoption of Invensys' ArchestrA® Technology Accelerates Via Repeat Customer Projects and New Products
Global Companies Implement More Than 125 Projects Built on ArchestrA Technology; Invensys in Booth #4811 at National Manufacturing Week

CHICAGO, NATIONAL MANUFACTURING WEEK, Feb. 23-26, 2004 -- Invensys announced today that customer adoption of ArchestrA technology is accelerating with repetitive rollouts on Invensys projects, and new Wonderware software products that add value to multi-vendor, legacy system installations.

Wonderware has been shipping the Industrial Application Server, which is built on ArchestrA technology, for just over one year. To date, more than 125 automation and information projects have been completed or are underway at leading global companies across a broad range of industries, including oil and gas, food and beverage, chemicals, pharmaceuticals, paper, automotive, steel, electronics and utilities.

These diverse customer project applications feature remote SCADA operations, plant-wide supervisory control, plant intelligence, regulatory compliance, production management and enterprise collaboration.

Recent repeat orders are coming from companies such as DaimlerChrysler, General Mills, Georgia-Pacific, Nucor Steel, SABMiller and Trusjoist, a division of Weyerhauser Corp.

In addition, Wonderware has shipped more than 2,500 copies of FactorySuite A² software featuring the ArchestrA integrated development environment to customers as part of its comprehensive software support agreements. The "A-squared" indicates the presence of ArchestrA technology.

"The ArchestrA technology vision of enabling the rapid and effective capture and reuse of intellectual property is now a reality for Wonderware customers," said Mark Davidson, vice president of global marketing for Invensys' Wonderware and ArchestrA business units.

"We are very pleased with how customers across diverse industries are re-implementing their company engineering standards and deriving significant productivity benefits from products that utilize ArchestrA technology. Within the past months, approximately 6,000 people have experienced ArchestrA technology with FactorySuite A² products using our online ArchestrA Technology Test Drive."

The ArchestrA Technology Test Drive can be accessed via www.invensys.com/archestra.

More than 120 third-party systems and plant networks are now classified as "ArchestrA Ready," allowing a wide range of current plant data sources to plug into ArchestrA applications. Ten Invensys and third-party systems offer even higher levels of ArchestrA integration. These include offerings that are "Integrated with ArchestrA" for advanced communications and diagnostics, and offerings "Built on ArchestrA" for instant integration of the most common industrial application functions such as plant modeling, configuration, alarming, historization, scripting and IT integration using Microsoft® .NET technology.

The latest Wonderware software offering leverages customer investment in legacy GE Fanuc iFIX® and FIX™ 32 HMI installations is an ArchestrA proxy object. Wonderware application engineers and systems integrators have contributed downloadable and reusable application object templates to the ArchestrA Application Object Warehouse to facilitate rapid application assembly and re-use.

For a complete listing of shareware software objects, products, programs and user forums that support the ArchestrA community of interest, please visit www.archestra.biz. ArchestrA development tools and software technology are openly available to third-party systems integrators and OEMs to help make them more competitive and encapsulate their unique domain knowledge and value-add.

Invensys continues to work closely with Microsoft Corp. to ensure that customer applications built on the ArchestrA software architecture meet the mission-critical needs of industry while evolving effectively as the Microsoft Windows® Server System and Microsoft .NET technologies evolve. Microsoft and Invensys recently formed an alliance to work together to market and sell Invensys products and solutions that use ArchestrA technology.

"Invensys is a good example of a Microsoft partner taking advantage of a full range of Microsoft's products and technologies -- BizTalk Server 2004, SharePoint Portal and Live Communications Server -- to ensure that the ArchestrA environment delivers collaborative solutions across discrete, process, hybrid and building industries," said Don Richardson, director, manufacturing industry solutions at Microsoft.
