Emerson’s Terry Blevins has been a driving force in much of the advancements in process automation. In the early days of the DeltaV system developments, he was at the heart of the Foundation Fieldbus standards development. As technologies advanced and it became possible to put advanced control algorithms in controllers rather than host level computers, Terry was again at the forefront working to add model predictive control, neural networks, fuzzy logic, and most recently continuous control performance monitoring into the DeltaV system.
Over at ModelingAndControl.com Terry shares his wisdom gained over many years for the next generation of automation and control engineers.
So why am I telling you all this? It’s because today the ISA announces, ISA Standards Committee Launches EDDL Website. Terry, as the chairman of the SP104 committee, was integral in making this happen. Earlier this year, he summarized the goals of the SP104 committee well in this blog post.
He even enlisted me to seek out the EDDL.org domain, secure it, and donate it to the ISA organization. I was more than happy to help.
The EDDL.org site clearly states what EDDL is all about:
Electronic Device Description Language (EDDL) technology is used by major manufacturers to describe the information that is accessible in digital devices. Electronic device descriptions are available for over 15 million devices that are currently installed in the process industry. The technology is used by the major process control systems and maintenance tool suppliers to support device diagnostics and calibration.
Terry was concerned that information about EDDL was scattered around a number of sites including the HART Communication Foundation, Fieldbus Foundation, and Profibus International. This made it difficult for automation professionals to learn about this important standard. The goal of EDDL.org as described in the press release:
The website is a good way for interested parties to learn how to ensure long-term viability of device management solutions, protect their investment in these systems and easily keep it current, ensure security and robustness… The site also features links to training, technical articles about EDDL, online tutorials, and other related standards efforts.
Standards have played and will continue to play a key role in process automation as process manufacturers increasingly rely on the technologies to get their process operations running efficiently and being able to serve their customers better.
