Wonderware Releases Version 2.2 of DT Analyst™ Plant Productivity Improvement Software New Version Increases Efficiency and Operator Involvement

LAKE FOREST, Calif., Oct. 13, 2003 -- Wonderware, a business unit of Invensys Systems Inc., today announced the availability of version 2.2 of the award-winning DT Analyst plant productivity improvement software. DT Analyst software provides Overall Equipment Effectiveness (OEE) calculations and other key plant metrics useful in improving equipment performance and availability. Version 2.2 enhances customer efficiency through improved report navigation and event categorization.

DT Analyst software offers plant decision-makers industry-standard key performance indicators (KPIs) such as OEE, which compares manufacturing operations throughout the plant and across the enterprise in near-real time. This allows senior management to enforce productivity improvement initiatives throughout the company and compare plant production lines, shifts or parts of a production line, enabling managers to target or set priorities for areas of improvement.

High-speed, high-volume manufacturing operations can benefit immediately from OEE. OEE calculations provide a complete picture of a plant’s operations, including system and equipment availability and performance measurement, which helps managers ensure that operations are running at rated production levels. As a result, plant personnel from the plant manager to the plant-floor operator can visualize the effectiveness of plant assets using OEE and determine how well equipment performs in real time with the implementation of process improvements or changes.

For example, short-duration packing machine stoppages can be measured and analyzed to evaluate how they affect the production line’s OEE. The DT Analyst event monitor helps plant operators identify and correct problems. After a solution is applied, plant staff will be able to immediately measure the solution’s effect.

“Wonderware products are known for their ease of use and efficiency,” said Jim Frider, product marketing manager for Wonderware’s plant intelligence products. “This new release of DT Analyst software continues in that tradition because it detects and resolves recurring availability, performance and quality issues, decreasing costs and increasing profitability without large capital outlays.”

DT Analyst 2.2 also has expanded the application’s multilingual support. It now supports German, French and Spanish, with additional language support in development. Regional settings are now configurable, and version 2.2 supports a broader range of non-English-language operating systems.

“Many of Wonderware’s largest DT Analyst users are international manufacturers focused on improving productivity and asset utilization,” Frider said. “DT Analyst 2.2 software provides better support for these important markets.”
