Several major vendors have now announced plans to fully support enhancements to the electronic device description language (EDDL) used by HART devices, reports Ed Ladd of the HART Communication Foundation. These enhancements will allow users to interact with their intelligent devices in new ways. They ease configuration, even of complex instruments, and support storage of historical data for troubleshooting and diagnostics.
In a random drawing in July, John Cengel of Cognis Corp., Cincinnati, Ohio, was selected to receive a 20-GB iPod for taking part in
Chemical Processing's Readers' Choice Survey. We congratulate John and thank all those who participated in the survey, whose results appear in August's issue.
Want to know which suppliers of products and services your peers think are the best? Readers pick the top technology providers in more than forty categories of products and services employed at chemical plants.
Batch material transfer control seems an easy task to carry out, but the reality is that many functions are necessary if the system is to accomplish accurate batch material transfer control. Weighing systems with device-level controls can help.
Many chemical companies, prompted by factors such as a lack of in house expertise, equipment and permits for making certain materials, are moving production outside. Tollers, in turn, are seeking to become their partners, not just contract manufacturers.
Keep a few pointers in mind when sorting through proposals for distillation column internals. They will make it easier to equitably compare the quotes, including assessing performance claims and even alternative hardware recommendations.

The 2005 meeting gathered 50 participants for two days of presentations and discussions. The agenda covered basic information about CAPE-OPEN and CO-LaN, reports on recent implementation and interoperability successes.
The primary purpose of CO-LaN is to promote the use and the development of the CAPE-OPEN standards in Computer-Aided Process Engineering (CAPE) software, and more generally to encourage all actions aimed at facilitating the use of CAPE software tools in industry, government agencies and academia.
Despite the appearance of digital fieldbus technology in plants, well-proven HART technology still has a viable long-term role, notes Ed Ladd of the HART Communication Foundation. He adds that industry consultants predict that HART easily will be supported and remain a significant communications technology for the next 20+ years.
