Invensys’ Wonderware® Business Unit Receives Editors’ Choice Award from Control Engineering Magazine for Industrial Application Server
Product Recognized as One of the Most Innovative Applications of 2003

LAKE FOREST, Calif., Jan. 16, 2004 -- Wonderware, an operating unit of Invensys Systems, Inc., today announced that Control Engineering magazine has selected the Wonderware Industrial Application Server product for its 2003 “Editors’ Choice Award.”

The Editors’ Choice Award winners are selected from among new products featured in Control Engineering, Control Engineering Online or one of Control Engineering’s topical e- newsletters.

“Our editors review literally hundreds and hundreds of new product announcements each year, and only the best are chosen for publication,” said David Greenfield, editorial director of Control Engineering magazine. “The winners are chosen from among those products we’ve covered during the past year -- both in print and online. At the end of each year, the editors of Control Engineering select the Editors’ Choice Award winners based on three criteria: market impact, service to industry and technological advancement.”

Built on Invensys’ ArchestrA software architecture, the Wonderware Industrial Application Server is designed to significantly reduce engineering time and the costs of application ownership and maintenance with a flexible and extensible software framework. Industrial Application Server applications can perform real-time data acquisition, alarm and event management, data modeling and manipulation services as well as collaborative engineering capabilities.

“The fact that the editors of Control Engineering selected the Wonderware Industrial Application Server for this award is a significant achievement for Wonderware and Invensys, which developed the ArchestrA architecture on which the Industrial Application Server is based,” said Steve Garbrecht, product marketing manager for Wonderware’s Industrial Application Server. “Many customers will benefit from the Industrial Application Server because they do not have to update or replace existing systems or supervisory applications to use it, but can simply add it as a value-added information layer without disrupting plant production.”

With the Industrial Application Server, new applications can be easily assembled from a library of standard, reusable components, or objects, without writing or compiling new code, which can help customers save significant amounts of money and time. More information on the Industrial Application Server is available at www.wonderware.com/products/appserver.

“This award, which is ranked among the top in our industry, validates our strategy to provide a comprehensive plant automation and information architecture designed from the outset to extend the life of legacy systems by leveraging the latest software technologies,” said Mark Davidson, vice president of global marketing for Invensys’ Wonderware and ArchestrA business units.

As one of 35 Editors’ Choice Award winners, the Wonderware Industrial Application Server will be eligible to win a Control Engineering “Engineers’ Choice Award,” to be announced at National Manufacturing Week on Feb. 24, 2004. Control Engineering will survey its subscribers to select winners for the Engineers’ Choice Award.
