Fieldbus has proven its merit in bringing projects online more efficiently, allowing better diagnostics, and control, and reducing maintenance costs and inventories. However, it has been limited in intrinsically safe services. At last, technology has come through once again with a solution. The capacity barrier of FISCO has now been significantly surpassed by a novel split architecture design that has already proven itself in the field.
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.
Good installation is crucial for trouble-free startups and optimum tower performance. Experienced installers share their practical knowledge to help you make sure that your tower will work as expected. The advice also applies to absorbers and strippers.
Understanding how changing a work environment affects people can reduce accidents. Management of Change (MOC) has been one of the hardest of the PSM requirements for industry to master. Making matters worse, its rarely applied to people and organization changes. But there are proven approaches.

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.
In this month's installment of On the Bus, Contributing Editor John Rezabek predicts HART devices will work so well that your career may be over before you can justify the cost to replace them with fieldbus.
