Cable requirements for FOUNDATION fieldbus are different from 4-20mA networks. That’s why we have many kinds of cable that have been tested and registered by the Fieldbus Foundation. Jim Cahill over at Emerson Process Experts blog actually has a great post regarding a conversation that was going on in the Fieldbus Foundation LinkedIn group, where users were discussing cable requirements.
This goes into interesting territory because there is always the ongoing debate among solution providers and end users as to whether or not existing cable can be used in a retrofit fieldbus project. Existing cable can be used in some circumstances, but you have to watch out for inductance, capacitance, and resistance.
You may have noticed that ISA has launched a new standards committee, of which I have the privilege of being a member. The ISA108 Intelligent Device Management standards committee “will define standard templates of best practices and work processes for design, development, installation and use of diagnostic and other information provided by intelligent field devices in the process industries.”
Let me be clear that this is not a FOUNDATION fieldbus-centric standard. This standard applies to anyone who is using intelligent field devices on any network. In many cases, the promise of intelligent field devices in process plants remains unrealized. This is not so much a technology issue as a people or work process issue. Too many users are employing old maintenance work processes with new technology. The new devices and applications are installed, but the operators and technicians stick to their old way of doing things, their old preventative or routine maintenance practices, and never really take advantage of the huge amount of information that is available to them. It seems clear that the process industries would benefit from a standard set of work processes and best practices for intelligent device management. This would give end users an effective blueprint for achieving the significant economic lifecycle benefits associated with intelligent devices.

The Fieldbus Foundation today announced that Fieldbus Inc. has qualified under its FOUNDATION Development Services Provider (DSP) program. A solutions provider for fieldbus technology applications, product development, standard and custom function blocks, consulting, training and many other products and services,. Fieldbus Inc. joins other qualified service providers in the program, which helps automation vendors get started with FOUNDATION product development by making it faster and easier to bring fieldbus equipment to market.
Fieldbus Foundation Manager-Fieldbus Products, Stephen Mitschke, commented, “The FOUNDATION fieldbus technology market continues to grow, and Fieldbus Foundation members look to participate in it. Sometimes, organizations can be intimidated by fieldbus device development when they are faced with little experience or knowledge of digital bus technology. Add in limited resources and they may prefer to outsource a portion of the development process. The FOUNDATION DSP solution can help by streamlining product R&D and ensuring a strong ROI.”
Tom Boyd, vice president, engineering, Fieldbus Inc., said, “As a recognized expert in field communication technologies for the process automation industry, a key participant in the development of fieldbus product solutions and an active member of the Fieldbus Foundation, Fieldbus Inc. sought the DSP qualification to continue our support of the technology and the manufacturers wanting to use it. The Development Services Provider program is an excellent way to expand our role as a high-quality FOUNDATION technology provider.”
FOUNDATION DSP program participants and their development tools/services are featured in a special section of the Fieldbus Foundation’s website (www.fieldbus.org). Go to the Development Services Provider page for information on Fieldbus Inc. as well as our other DSP participants. Participants are also authorized to display the official FOUNDATION DSP logo in their marketing materials.

Fieldbus Foundation will be hosting another free-of-charge end user seminar at the Hilton Americas Hotel in Houston on September 12th. Our first end user seminar in May of this year received great reviews, and we believe this is our most interactive and instructive series of end user seminars we have ever done. We do hands on demonstrations of FOUNDATION technology throughout the phases of the plant lifecycle, from engineering and design to operations and maintenance. Our speakers include end users and leading fieldbus trainers and educators, as well as some very knowledgeable representatives from leading suppliers such as Emerson, Invensys, and Yokogawa. You can get more details and register electronically here.

Trine University in Indianapolis, Indiana was one of our first FOUNDATION Certified Training Program (FCTP) partners, and we are pleased to announce that they are the first FCTP partner to add remote learning capabilities to the FOUNDATION Certified Professional course using a hybrid delivery method — classroom and hands-on lab training combined with online lectures and tests.
The FOUNDATION Certified Professional Certificate is geared toward engineers, designers, main instrumentation controls contractors, and startup and commissioning specialists wanting to increase their knowledge base of design, planning and implementation of FOUNDATION systems. Until recently, this vendor-neutral, comprehensive full-week course at Trine University was a hands-on class that covered all areas of Fieldbus instrumentation: design, installation, configuration, maintenance and troubleshooting.
“In order to meet anticipated growth, make training more accessible and reduce costs for trainees, Trine is continuing to implement significant changes. By decreasing the time students spend on campus from five to four days, the latest change allows double the time for hands-on learning, which affords students a greater experience. They will learn more in the way of installation methods, diagnostic tools and troubleshooting methods. In addition, trainees can remain in the workplace while accessing lectures and tests online. Students have access to “chat rooms” to discuss points or ask questions. This hybrid delivery method is more accommodating to potential foreign and domestic students.”
“The FOUNDATION Certified Support Specialist and Technical Specialist courses will also be available in the hybrid format in October 2012. A fourth FOUNDATION certified course (Installation) will be available in 2014.”
““A critical component to the success of fieldbus training at Trine University is our instructor Dave Lancaster. Through his excellence in teaching, curriculum development, and 44 years of experience in the engineering and contractor business, Dave is an invaluable asset,” said Mersiha Alic, program director. “In addition, he secured over $250,000 of donations in lab equipment from a variety of vendors, expanding the size of the new lab at Trine’s Regional Campus in Indianapolis, allowing high-quality, vendor neutral training.””
Many end users are opting for remote learning options so they can spend more time on their plant site and reduce travel costs. The ongoing labor crunch, combined with advancements in Internet-based remote training technologies, are now making it not only possible but necessary for training institutions to add a remote component to their course offerings. We look forward to more of our FCTP partners adding remote training options to their course offerings in the future.
We at the Fieldbus Foundation have recently made some updates to our device coupler test specification. For the uninitiated, device couplers or isolated device couplers (where applicable) are installed where the fieldbus trunk (i.e., home run cable) is connected to the various device spurs. Isolated device couplers are specifically designed to allow automation end users to connect more devices per coupler while permitting live segment work in hazardous plant areas. These couplers provide isolated, conditioned power to multiple fieldbus devices and protect against short circuits caused by excess current in a spur. By enabling more devices per segment, they also help reduce controller input/output (I/O) points and associated installation costs.
The FOUNDATION fieldbus device coupler test specification includes criteria from the international IEC 61158 standard and additional functional tests such as input impedance, short-circuit reaction time, and bus voltage consumption. The specification is designed for coupler manufacturers to perform a standard set of tests against their implementation. A team of volunteers comprised of current members of the foundation who supply coupler products, as well as end users employing registered couplers, developed the test cases.
We are at the ISA Water/Wastewater and Automatic Controls Symposium in Orlando this week. ISA has invited us to this conference to present on FOUNDATION for Remote Operations Management. The water and wastewater business has a significant amount of remote operations and could benefit significantly from FOUNDATION for ROM. The water and wastewater industry must also make some pretty significant investments in its overall infrastructure over the next decade, including automation. Thanks to ISA for letting us participate and we look forward to a good meeting. I am actually at the conference right now and this is the most water and wastewater industry end users I have seen in one place, about 175 people in all.
Nancy Bartels, Managing Editor for Control magazine, has written a nice article about FOUNDATION for ROM and some of the confusion that exists surrounding the numerous wireless standards in process automation, and some of the technologies designed to integrate these various standards, FOUNDATION for ROM being one.
