Wonderware Strategic Integration Group Wins $1.5-Million Aventis Contract
Vaccine Business Develops Innovative Application Using Wonderware InBatch Production Management Software

LAKE FOREST, Calif., Jan. 28, 2004 -- Wonderware, a business unit of Invensys Systems, Inc., today announced that its Wonderware Strategic Integration Group (WSIG) has been awarded a $1.5-million contract to provide Aventis (NYSE:AVE) with a new automated manufacturing system application. This innovative system application is designed around the award-winning Wonderware InBatch production management software.

Aventis Pasteur, the vaccine business of Aventis, is implementing the Wonderware solution as part of the $77.5-million expansion of its Swiftwater, Penn. formulation and filling plant, which is the company’s largest expansion project to date. The WSIG solution will enable Aventis Pasteur to expand and improve vaccine production.

“Wonderware has a long history of providing the pharmaceuticals industry with applications that are designed to enhance the manufacturing process and improve product quality,” said Yves Dufort, WSIG’s general manager and director of services. “The new InBatch production management system will enable Aventis Pasteur to achieve significant benefits such as increased plant efficiency through reduced processing errors, faster batch-release cycles and reduced operating costs.”

The contract involves the supply and configuration of user interfaces to automate batch processing with data-entry screens, a real-time database and visualization layer as well as batch production execution and reporting systems. The solution is designed to provide Aventis Pasteur with a flexible rapid-response modular processing capability to manufacture multiple batches of its brand-name products.

The project will provide Aventis Pasteur with a centralized system that seamlessly integrates the operational capabilities of its new Swiftwater formulation and filling facility for input/output devices, control systems and execution systems. WSIG will design the solution to give Aventis Pasteur the ability to access and share the appropriate information with the right people, improving the decision-making processes. In addition, it will enable the company to coordinate activities and resources for the formulation and filling facility.

Other project objectives include eliminating paper records, batch sequencing, alarm and notification of adverse conditions and real-time exception reporting to facilitate batch evaluations. The system will provide continuous and comprehensive data collection for historical records. The collected data can then be used for process optimization and improved efficiency.

As a four-time winner of Control magazine’s “Readers’ Choice” award for batch software, InBatch software offers unparalleled capabilities to automate highly complex batch applications that require flexibility and comprehensive history logging.
