Another stellar article by John Rezabek, Ashland Chemical, was published in Control’s magazine last month, and I’d like to highlight it. John, as many of you may know, is the End User Advisory Council Chairman for the Fieldbus Foundation, and a big reason for this is his experience, depth of knowledge, and motivation to understand and keep up with the latest trends in fieldbus.
His article covers the message of what some users have heard about “bitter” experiences with fieldbus in its original days. John goes on to explain the key game-changing factors in successful projects as well as advancements that have and will make things even easier for users. There is no reason fieldbus can’t be a highly-successful wonderful experience for users (John is one of many examples of a user reaping massive benefits from smart digital technology).
As usual, there is no reason to spoil the message and writing John has so eloquently put together so follow the link below to read his post.
Be sure to check out the newly released Fieldbus Report posted today! The bi-annual Fieldbus Report is your resource for all things FOUNDATION. It has the latest news, fieldbus solutions, programs and initiatives being developed by the Fieldbus Foundation. It also contains a comprehensive list of the latest registered fieldbus products so you can be sure you keep up to date with the latest technological advances.
Be sure to grab a copy and read about the new Fieldbus Foundation Usability initiative we’ve been writing about! You can find the latest Fieldbus Report (as well as past versions) by going here: Fieldbus Report
Success! The Fieldbus Foundation’s North American Marketing Committee participated in the first seminar of 2014 year in Calgary, AB Canada on June 5th and 6th.
The engineering offices of Fluor in Calgary started the successful week by hosting the Fieldbus Foundation for a lunch and learn for over 35 engineers from the Quarry Park and Sundance locations. The event was led by Talon Petty of the Fieldbus Foundation with subject experts Mike Clark – BusCorp, David Lancaster – Previously of Bechtel, and John Rezabek – Ashland Chemical. The event was very well received by the engineers who showed a strong understanding of FOUNDATION fieldbus, yet also a thirst for the latest information.
Mike Clark presented on the topic of what the Fieldbus Foundation dubs VirtualMarshalling. Mike’s presentation, titled “Why Make Marshalling Smarter, When You Can Eliminate It?” discusses the solutions available in the industry and how they each work from a schema perspective. Some folks often wonder how they can make marshalling smarter or more user friendly, but from the perspective of FOUNDATION fieldbus, electronic marshalling was eliminated the day FOUNDATION fieldbus was created. With FOUNDATION, the marshalling doesn’t require any hardware or software configuration changes, it’s simply all there. It’s done natively in FOUNDATION fieldbus. Devices simply tell the user what they have available, and the user configures the device as they see fit.
Dave Lancaster presented on the topic of Host/Device Selection. This very important step can often be under-evaluated because a few exciting device features sold a device to the user before he/she could properly understand its capabilities compared to it’s required use case in their application. Fully understanding a users application and needs, give the users the ability to make important selection choices, and when the user spends the extra time fully understanding the impact of his/her choices during the host/device selection, the project is more successful overall. Dave’s presentation offers key consideration points for users and engineers to think about during the selection phase.
A big thanks goes out to all of the engineers at Fluor that participated in the lunch and learn and the team there at Fluor that helped coordinate the activity.
The event on June 6th, hosted at Hotel Arts in downtown Calgary, was the 2nd event in as many days and was a smashing success with roughly 130 registered attendees for the day-long event. The event covers a full project lifecycle from infrastructure selection to maintenance and device replacement. You can read the full agenda here: Calgary Agenda.
Hosting some of the most knowledgeable FOUNDATION experts in North America, the seminar challenged some past notions and offered some helpful best practices based on years of experience. The 2014 seminar is all-new down to the demo system on display. In the past years, the demonstration units showed static devices on display, but in 2014 the new unit actually runs a live process during the event to fully immerse the audience and to illustrate how powerful FOUNDATION fieldbus is for process applications. One particular such instance is when we illustrate Control in the Field (CiF). After demonstrating the redundancy and robustness of the host system, a catastrophic failure is simulated via complete loss of the control system. Despite total loss of the DCS, the attendees see continued control of the process level application via CiF. To take it a step further, a dump valve is opened to show an immediate loss in level after which the valve goes full open and continues to maintain level even with this additional process disruption. It’s a powerful demonstration.
There are 2 more seminars in North America currently scheduled for 2014. The locations are Baton Rouge, LA and Houston, TX (Sept 15-16 & Sept 17-18 respectively). If you’re in either of those areas be sure you sign up to attendee the new seminar, you won’t regret it! You can view additional information at http://fieldb.us/seminars-2014. Other global seminars can be found by going to http://www.fieldbus.org and browsing under the “Global” section of the website for specific regions.
Another big thanks goes out to all of our seminar sponsors that allow us to host these events free of charge to attendees. These guys have great FOUNDATION fieldbus solutions to showcase to attendees at each show.

I was attending one of our great seminar roadshows a couple of years ago and was asked by a user how they can know when new versions of their favorite products have been registered. The simple answer was to encourage them to talk to their supplier directly, but upon further digging, I realized this was something not being well addressed by the process community at large. How are the users supposed to know when a new device is available? If they don’t know they’re a newer versions available how can they upgrade an old device that may not have the full capabilities they require in their demanding application?
The answer is to track and update our members and newsletter subscribers about the latest registered products and to direct them to their appropriate registration page for more information.
If you’ve ever wanted to keep up with learning when new products are available after official registration, be sure to sign up for our electronic newsletter “Fieldbus Flash”. You can do so here: http://www.fieldbus.org/index.php?option=com_content&task=view&id=217&Itemid=387

The Fieldbus Foundation today announced the latest updates to its open, non-proprietary FOUNDATION fieldbus specifications. These updates help automate device replacement and enable backwards compatibility among different revisions of FOUNDATION devices used in plant automation systems. End users will benefit from greater predictability in fieldbus implementation, while reducing integration risks and eliminating manual intervention for device configuration.
The most significant updates to the Foundation technical specifications are a revised series of function block and transducer block profiles, as well as requirements for H1 (31.25 kbit/s) device replacement that are now part of the Fieldbus Foundation’s device registration process. This enhancement enables the H1 interoperability test kit to verify consistent behavior between device and host implementations in fieldbus-based control systems.
Automation of device replacement allows the configuration in an existing field device to be restored in a newer version of that instrument without manual intervention. This ‘plug and play’ solution ensures features are consistent between different generations of devices without reengineering the host configuration or changing any other element of the H1 network other than the new instrument.
In addition to device replacement, the specification update provides improved positioner profile in fieldbus devices. This technology supports organization and integration of advanced device diagnostics within fieldbus systems. It provides standard definitions for positioner transducer blocks and includes parameter structure definitions for better data organization with fieldbus devices, including partial/full stroke test (PST/FST) of valves.
