Integrated digital field networks are increasingly popular but pose particular safety and security risks. Fortunately, a number of parallel activities are underway to make integration between automation and business systems effective, safe and secure.
Users seeking appropriate process safety systems arent getting enough help from unspecific standards and ideal-world certifications. Heres how to gain useful safety capabilities in a buyer-beware world.
New anti-terrorism standards require the Department of Homeland Security to identify and regulate "high-risk chemical facilities." These facilities will be subject to a security vulnerability assessment. Where does your plant fit in with these new standards?

For maintenance and condition-monitoring, wireless technology offers much more than just reducing or eliminating costs. However, wireless also requires an integrated infrastructure approach rather than independent, proprietary point solutions.
Efforts to tighten communications of condition-monitoring instrumentation and data analysis software with CMMS and automation infrastructure, combined with the proliferation of wireless sensor systems and the drive to reduce manpower skill and time requirements, are bringing implementation costs down and drawing much attention to this approach. But should you implement it?
More attention to mercury and increased acceptance of predictive approaches is emerging. Such monitoring not only can keep plants on the right side of regulators but also can help provide insights for optimizing operation of equipment.
This article addresses cost estimating for capital projects on which an analyzer system is installed, through start-up and commissioning of the project, to the resultant lifetime cost savings that can be gained.

More and more companies are placing greater emphasis on maintenance and seeking help from vendors to boost the effectiveness of their efforts, as some recent major investment decisions demonstrate. Many automation companies now are benefiting by building up asset management services alongside process control capabilities.
Classic distributed control systems typically remain only in high-availability refining and power applications, but their strategies and capabilities persist in descendants and todays sophisticated networks.
