Manufacturing companies are looking for more ways to maximize existing resources, and many are using asset-management technology to boost return on investments in plant equipment. Industrial automation company Rockwell Automation, Milwaukee, has raised the bar on asset-management solutions with the 2002 introduction of the Entek XM Series. According to Rockwell, Entek XM's sweet spot is the combination of machine monitoring and protection into one system that is less expensive and easier to use than current systems. Rick Schiltz, vice president of capabilities and engineering for Rockwell, says that limited staffs and budget restrictions are keeping many companies from taking a preventive tact to asset management. A survey Rockwell sponsored in May 2002 shows that only 15% of companies are using a predictive strategy to manage machinery. Research based on IndustryWeek's North American Best Plants program illustrates the value of predictive maintenance: The top plants since 1992 used reactive maintenance an average of only 25% of the time. Predictive maintenance was reported in use nearly 70% of the time. These plants averaged machine availability of 96%. Still, says Schiltz, many plants are unable to use predictive maintenance because they can't gather enough machine-related information effectively. "Many are checking their equipment quarterly because they have so much equipment," he says. "They need more information, but upgrading is too costly." Rockwell touts Entek XM as a breakthrough response to this because of its:
