Invensys' Wonderware Strategic Integration Group to Deliver Predictive Maintenance Solution for Engelhard Corp.
WSIG Project Expected to Reduce MRO Inventory, Downtime and Labor Costs

LAKE FOREST, Feb. 23, 2004 -- Wonderware, a business unit of Invensys Systems, Inc., today announced that the Wonderware Strategic Integration Group (WSIG) just received its first purchase order for its Predictive Maintenance solution from Engelhard Corp., a long-time Wonderware and Avantis strategic customer.

The solution consists of a series of ArchestrA software objects that run on Wonderware's Industrial Application Server, which facilitates automated updates from the plant floor to drive maintenance work orders in a computerized maintenance management system (CMMS). This interoperability solution will provide real-time connectivity between the shop floor and Engelhard's Avantis CMMS installation.

"WSIG Predictive Maintenance solutions can yield high returns on investment," said Yves Dufort, WSIG's general manager and director of services. "This solution is designed to reduce overtime and maintenance labor costs; cut down MRO inventory; decrease planned downtimes through better-planned maintenance; lessen unplanned downtimes through more timely maintenance; and improve coordination between the maintenance and production departments, to minimize disruption."

The WSIG Predictive Maintenance solution includes software and project services that link a plant's maintenance system with equipment usage. As part of the design of this Predictive Maintenance solution, an adapter for the MRO software's Maximo CMMS is also being created. These offerings leverage Invensys' ArchestrA software architecture to link maintenance events and plant production data.

"We decided to implement the WSIG Predictive Maintenance solution because we expect it to reduce our MRO inventory, decrease planned and unplanned downtimes, and lower our labor costs for maintenance labor and overtime," said Gary Yacobian, senior engineer for Engelhard. "It should also minimize disruptions in production by improving coordination between our maintenance and production activities."
