PITTSBURGH, PA, December 18, 2001 — Emerson Process Management today announced the addition of AMSinside to the Ovation® Information & Control System of its Westinghouse Process Control business.

This new feature of the groundbreaking, open-architecture Ovation System expands the benefits of PlantWeb® Digital Plant Architecture, enabling power generation companies to incorporate field intelligence into day-to-day operations to improve plant performance and cut costs.

AMS software analyzes information transmitted through Ovation from intelligent field devices to provide operators with the detailed information necessary to calibrate, configure and diagnose plant equipment more efficiently. Ovation communicates with HART and FOUNDATION( fieldbus devices, which when combined with AMS, form Emerson's revolutionary PlantWeb( architecture for the power generation market, providing the potential to cut maintenance costs further with more complete and timely plant information.

"Having AMSinside allows Ovation to turn existing information into maintenance savings for power generators," said Ann Pauley, president, Westinghouse Process Control. "Making decisions based on the kind of knowledge AMS and Ovation provide together not only offers plants the ability to realize their true potential, it can result in lower start-up and commissioning costs and can get plants online faster when demand increases."

The new Ovation with AMSinside software option reduces wiring requirements. Additionally, for plants using HART devices, it eliminates the need for extra multiplexers and converters.

The addition of AMSinside to the Ovation System is key to Westinghouse's drive to provide a competitive advantage to its customers through "Partnering for Power," a methodology of performance optimization for the power market, aimed at solving challenges faced in generation environments around the world. The methodology also integrates other industry- Emerson technologies and services including PlantWeb digital plant architecture. The architecture integrates the Ovation Information & Control System, Rosemount and Fisher intelligent field instrumentation, knowledge-based management solutions from AMS software, and a variety of maintenance, training, software, benchmarking and assessment tools.
