ISA108 Nearing Resolution of Comments on Part 1, Part 2 Work Beginning…

Committee Meeting & Timeline Update

The ISA108 Intelligent Device Management committee is meeting this week in Houston, TX at Yokogawa’s Sugar Land facility to rationalize comments on Part 1: Concepts & Terminology. Once resolution on the existing comments are complete, ISA108 will re-submit for a final round of comments to Part 1.

Also important at this week’s meeting, the group is beginning establishment of Part 2: Work Process Specifications. Part 2 will include the following subsections that require the establishment of working groups:

Part 2.1 – Configuration & Revision Management
Part 2.2 – Diagnostics Management
Part 2.3 – Procedure Management

All three of these parts are important elements in the Intelligent Device Management lifecycle. The group is currently looking for volunteers for all 3 of these sections. In addition to these 3 sections, there are proposals for Calibration Management and Valve Management. If there is enough support and volunteers, these subcommittees will be launched in conjunction with the other 3 parts. ISA108 encourages manufacturers, engineering partners and users to participate in the committee in order to offer guidance and knowledge on these subjects.

After Part 1 & 2 is complete, the committee intends to create a Part 3 Implementation Guide.

More on ISA108 Intelligent Device Management

The goals of the ISA108 Intelligent Device Management committee is to do the following simultaneously;

  • Reduce Unmanaged Risk
    • Improve Health, Safety, Environmental, and Operability Performance
    • Manage Complexity
    • Reduce Impact of Failures
  • Achieve Sustainability
    • Assure adequate Human, Financial, and Infrastructure Resources
    • Lower Maintenance Costs
    • Improve Return on Investment

The issue the industry users face today is that intelligent field devices are pervasive, but the diagnostics that provide big ROI are often left not utilized or they are being used, they aren’t being prioritized. ISA108 aims to meet this need by establishing a standard well defined set of work processes and procedures that guide the users of intelligent field devices on best practices.

By establishing good work processes and procedures through the establishment and use of ISA108, a user can expect to gain the following advantages;

  • Allows Maintenance on Devices that Actually Need Work, Only When They Need Work
  • Can Give Detailed Information on Problems Before a Field Visit
  • Can Significantly Reduce the Need for Periodic Testing
  • Can Reduce Impact on Operations by Advance Warning of Failure
    • A Significant but Underutilized Opportunity
    • Biggest Incentives on Control Valves

Barriers to obtaining full benefit from smart instrumentation is significant for many users because it requires a change in traditional engineering practices and a cultural change in for maintenance workers who are used to physically interacting with devices. There is also an element of management buy-in/ownership that will reduce these barriers and allow full benefit to be gained.

That’s a Wrap! – 2014 FOUNDATION Fieldbus Seminar Series is Complete

Last week, the Fieldbus Foundation completed the last two seminars of 2014, ending a year of successful events in North America. 2014 brought many new challenges as the marketing committee, alongside a small group of dedicated folks, committed to the full revamp of the seminar program. A major part of that revamp project was to create a new demonstration unit, except with some new constraints.

Previously, our old demo units were massive steel “trees” with instruments hanging off them. While it made showcasing instruments easy, and the layout simple, they consumed a ton of space and were expensive and difficult to ship. Each case averaged about 3’x4′ in size and weighed roughly 300 lbs. We hoped to downsize dramatically to make a more compact demo that would fit within 3 or 4 medium sized Pelican cases. It’s is quite the task. Adding additional challenge to the downsizing, we wanted to create an actual working demo capable of running a live process. Letting uses see devices on a “tree” hooked up and communicating is great, but when you can show them the same instruments actually running a process and how they react during interruptions, that is just plain cool.

As readers of this blog may have seen, Fieldbus Foundation actually put together a blog post on the new demo unit already. You can check it out HERE.

All-New 2014 Live Process Demo

All-New 2014 Live Process Demo

Also revamped in the 2014 program were the presentations by the speakers. The idea was to base the entire day seminar on a full project lifecycle from inception to FEED and all the way through construction, operations and maintenance phases of a plant. The idea being to showcase FOUNDATION fieldbus along each step of a project. It proved to be a smashing success.

2014 Seminar Agenda

By conclusion of the series last week, evaluations have shown the seminars were very highly acclaimed with attendees calling it “The best seminar yet” and “Awesome”. In fact, each agenda item throughout the day were better reviewed than 2013. The program was given an average of 4.4 out of 5.0 by attendees on the year. A big part of making our seminars interactive and worthwhile for the attendees is the lighthearted atmosphere where speakers allow discussion during presentation and reward conversation. In the Baton Rouge & Houston seminars we passed out a fieldbus beaniecopter to the nerdiest (a.k.a. the best) question asked during the day. Below is a picture of the group awarding Mr. Hotaling for his great questions.

If you missed out on the seminars in 2014, or there wasn’t one in your area be sure to keep an eye out in 2015 as we move forward on the seminar series. Dates & Locations are yet to be determined so if you’d like to see a seminar in your area be sure to contact the Fieldbus Foundation. You can keep up with our Events page or subscribe to our e-Newsletter for the latest information on seminar events in 2015.

Do you Hunger for Open Standard solutions?

John Rezabek, in the latest issue of Control Magazine presents a simple question “Do users hunger for open standards?” If not, why not? Are the benefits of open standards just not clear or are they simply pushed to the back of a list of priorities? If you as a user are not demanding open, interoperable solutions that suit both the needs of you today, and tomorrow, are you not doing yourself a major disservice? At the very least, you’re inviting complex, one-off solutions that may end up being unserviceable a few years down the road as companies get bought up or shut down, or their custom integration engineers retire or move on.

John gives a great real world example from his plant on how scenarios play out 10 years down the road when these one-off highly customized solutions start having issues, and it’s a strong case for open standards. As John puts it, “…you just can’t be Apple to your customer and control every widget you sell”.

Be sure to read John’s story over on Control Global’s website here: http://fieldb.us/hungry

There is one way users can help stop fieldbus hunger, and that is with their wallets. By demanding open standards, users ensure plant longevity and future-proof their installations against proprietary, highly customized solutions that often come to an abrupt end when support discontinues.

Happy 20th Birthday Fieldbus Foundation

Today marks the 20th anniversary of the merger between ISP and WorldFIP as recognized by the business filings. So many things have evolved since the merger first happened and here we are 20 years later talking about a new merger between HART and Fieldbus Foundation to create FieldComm Group. Exciting times indeed. We all look forward to what the future will hold!

User Demand Drives Pace for Record Product Registration Numbers

Driving Growth

It seems digital process fieldbus can’t get away from people saying “it’s too hard” or “growth is flat”, yet every day in other areas of people’s lives they continue to adopt more and more digital technology. While unsettling as it is to hear that, the most unsettling part is that there seems to lack any evidence to support the conclusion. Why does someone believe it’s too hard? Where can they point to prove there is a stall in digital fieldbus growth? Somehow a message gets disseminated that fieldbus has reached some peak despite data from ARC stating fieldbus is still growing at double digit rates.

Are there regions where fieldbus isn’t as widely adopted as alternatives? Certainly. But are there also areas where fieldbus is overwhelmingly the de facto standard? You bet. It’s hard to argue there have not been projects that should have gone fieldbus, and instead went 4-20mA. It’s also hard to argue there have been projects that seemed certain to go 4-20mA but ultimately stepped into modern fieldbus. There are fieldbus “physics” to be considered. For a given negative story, there is an equal and opposite positive success story to counter. So what then are we to believe?

The Fieldbus Foundation sees it this way: user demand is responsible for driving registrations of fieldbus devices… and as of August 2014, user demand has pushed manufacturers to register record setting numbers of FOUNDATION capable process instruments.

Understanding the Impact of User Demand on Registrations

The data below is for FOUNDATION fieldbus specifically. It is sourced directly from our registration data and reflects a growth in FOUNDATION fieldbus by way of user demand driving increased development and registration.

When digital fieldbus was first introduced, there were only a handful of available device types. Today, thanks to user demand, there is a wide array of available devices to fit nearly every possible application each with their own unique set of capabilities and advantages.

Registered FOUNDATION Fieldbus Product Types

Registered FOUNDATION Fieldbus Product Types

This same user demand has led to the Fieldbus Foundation registering more devices with more companies every single year as it outpaces itself in frequency and rate of registration every year over the last 3 years. The Fieldbus Foundation also averaged roughly 15 new member companies per year during that same period.

3 Year Comparison of FOUNDATION fieldbus Product Registrations

3 Year Comparison of FOUNDATION fieldbus Product Registrations

As one can see, not only has FOUNDATION fieldbus been growing, it has just had the highest product registration month in all of  2014, registering nearly 30 devices. In fact, digging back through data to 1998, growth of product registrations with FOUNDATION fieldbus has never declined or become flat even once.

Looking closer at the sharp increase experienced in August (the end of the red line in the chart above), the Fieldbus Foundation actually had the highest number of product re-registrations since 2001…and we’re only now entering the 4th quarter of 2014. Additionally, the Fieldbus Foundation just registered the 3rd highest number of new product registrations since its founding. At current trends, the organization is projected to see the largest number of device re-registrations and new registrations in the 20 year history of the foundation. Let that sink in for a minute.

Yearly Product Registration Comparison since 1998

Yearly Product Registration Comparison since 1998

So what do the spikes in registrations mean? Well for starters, it means there is a clear and present economic business model for FOUNDATION fieldbus that manufacturers are capitalizing on. As the world has long since entered the digital age in nearly every facet of its life, it is only natural the process industries do the same. Digital provides obvious advantages over traditional analog systems, and Fieldbus Foundation feels that user demand comes from stronger standardization in the areas that the users require it and more flexibility where the users need it.

As the usability and simplicity of FOUNDATION fieldbus continues to improve and meet the needs of the user community, growth will continue as users demand more information and better awareness from their devices to run efficient operations that make reliable high quality products.

Social Interaction

Beyond the growth comparisons to the registration program, the Fieldbus Foundation has seen continued rise and involvement in social media across the globe. The official Fieldbus Foundation LinkedIn Group now has nearly 1,900 members and increases an average of 60 members per month. LinkedIn has shown itself to be a valuable way to communicate about FOUNDATION fieldbus installations with other industries experts. The level of interaction on each discussion post is impressive.

Fieldbus Foundation Group Growth on LinkedIn

Fieldbus Foundation Group Growth on LinkedIn

The @FOUNDATIONField twitter account has 1,885 followers as of this post with similar growth rates as the LinkedIn group. Twitter provides an immediate way people to interact with the organization and to read about current news and events natively on their mobile platform. Again, its the continued growth trend that illustrates user demand for FOUNDATION fieldbus.

The Fieldbus Foundation also utilizes a YouTube channel that has proven effective for spreading educational videos on FOUNDATION technology. It allows the organization to share great “how-to” videos and direct viewers to appropriate content they find useful when visual illustration is needed. For example, one of the most watched videos on the channel is a simple “how to” on wiring H1 fieldbus cable. This video alone has amassed over 16,000 minutes of viewing time. Growth in user demand for fieldbus has generated 50% more engagement in 2014 then in 2013. These numbers will continue to grow and expand as awareness of the channel increases.

Conclusions

The Fieldbus Foundation continues to see double digit growth across the globe and it shows in both the registration program and social conversations. Users demand smarter instruments, more efficient systems and real-time closed loop control. FOUNDATION Fieldbus helps achieve these demands, and in so doing, allows the user to make a salable product safely and reliably on-time and with minimal interruptions. If it wasn’t for this strong user demand, manufacturers wouldn’t have a feasible economic business model to continue delivering fieldbus products at unprecedented rates. It should be said that the Fieldbus Foundation shares its users enthusiasm in looks forward to closing out another successful year of growth and a record breaking year of device registrations. This is a great thing for the process industry.

The Fieldbus Foundation & HART Communication Foundation Will Merge

Austin, Texas, September 5, 2014 – The final step in constructing a single organization to lead process automation communications and integration technologies was completed when the members of both the HART® Communication Foundation and Fieldbus Foundation™ approved the merger proposed by their respective boards through a voting process that concluded on August 30. This completes a yearlong study and diligence period by a dedicated team of volunteers representing each of the foundations.

The new corporation, called FieldComm Group, will be led by a board of directors composed of representatives of the collective companies from the current boards of each foundation. Hans-Georg Kumpfmueller has been elected as the inaugural chairman of the board. Mr. Kumpfmueller will lead the direction of the FieldComm Group and oversee the addition of FDI LLC in mid-2015.

Mr. Kumpfmueller has served as a leader in setting the course of device integration in his role as chairman of the FDI LLC board and as CEO of Sensors and Communication at Siemens. He is convinced the formation of FieldComm Group is “a major step forward for the process industries by leveraging the strengths of each industry-leading protocol and adding the value of the next-generation integration strategy.”

The board has appointed Ted Masters as president and CEO of FieldComm Group. He currently serves in the same capacity with the HART Communication Foundation. Mr. Masters brings a wealth of instrumentation and controls experience to bear in addition to a deep understanding of the use of data analytics in enterprise systems.

Mr. Masters believes the creation of FieldComm Group is an unprecedented opportunity to build upon existing technologies and develop a single future vision toward harmonization of standards for the process automation industry worldwide. He said, “I am excited about the opportunity to work together with distinguished leaders and technologies around the globe to integrate valuable process intelligence from devices to improve the operations of our users.”

During the transition and integration of the two organizations, Richard J. Timoney will serve as executive vice president of FieldComm Group. Mr. Timoney currently is president and CEO of the Fieldbus Foundation. He commented, “The joining of Fieldbus Foundation and HART Communication Foundation will realize the automation industry’s goal of a single, unified body to support advanced digital technology. The efforts of countless individuals and companies have helped us reach this milestone.”

FieldComm Group will consolidate offices in Austin, Texas, and function as a single entity beginning January 1, 2015. Until that time, the HART Communication Foundation and Fieldbus Foundation will continue to operate independently.

Open Standards Impact

I found myself reading an interesting article today from Wired.com. It was an article on the “connected home” of tomorrow. As we see more and more of our lives pushed towards automation, it just seems natural that automation would extend into a smarter home. In fact, I have a digital meter outside my home that not only provides my electricity provider the convenience of reading my meter remotely, it also allows me to view my energy consumption from a day to day basis…even down to a hour by hour basis. It’s really cool stuff. Every week I receive an email that details my electricity use each day, and even gives me the high and low temperatures in my city on those days. Even more impressive, I can compare the usage over time (last week, last month etc.). Still further, I have a Wi-Fi connected thermostat that allows me to setup, monitor and change my thermostat without ever having to get off the couch or even be at home altogether. Life is grand.

As more and more start-ups begin designing more complex advancements into our homes to automate things like our lights, TVs, dishwashers etc. the more we put ourselves at risk to cyber attacks. There is an inherent risk with opening your home to outside connections, but those risks exponentially increase with obsolete systems or buggy works done by low budget automation houses. This is where standards can help and where on line in particular from the article stuck out to me: “The best way to ward off…problems before they metastasize is to embrace openness.”

I will not argue that open standards are inherently more secure than a proprietary solution, but in general there are many reasons why it actually can be. The difference is in world-wide usage of a standard. Proprietary solutions tend to be developed and maintained by a smaller group of highly trained unique individuals. Open standards by contrast are spread widely, and are adopted and implemented by many. The benefit being that buggy back-door findings and strange anomalies get detected sooner, and can be fixed purely based on the number of individuals interacting with it. It’s the same principle that makes “group think” so powerful. 

Often, proprietary systems run by a core group of individuals lack the outside view of others. Ever heard the saying “Can’t see the forest for the trees?”. This is the same idea. The core group gets so engrained in doing what they do, that they cannot see a flaw if it exists. I’m sure the people over at Siemens would love to have prevented the Stuxnet virus that left a big black eye against their teal coloring. I think everyone can agree on that.

By adopting open standards, individuals and companies can minimize risk and ensure longevity to their investments. Open standards are owned or run by one single manufacturer so if one goes bankrupt or can’t offer the solution you need, another is there to take its place.

Long live standards-based protocols! Long live fieldbus.
