Fieldbus Foundation demonstrated FOUNDATION fieldbus technology at Interkama 2006, April 24-28, in Hannover, Germany. Interkama is billed as the "world's leading trade fair for process automation."
The Fieldbus Foundation stand featured informational kiosks showing FOUNDATION fieldbus applications and solutions through displays and demonstrations of registered devices, host systems, tools, and services available from at least 16 of leading automation equipment suppliers. Technology experts on hand helped visiting end users, integrators, contractors, and engineers acquire information and to exchange fieldbus application experiences. FOUNDATION fieldbus High Speed Ethernet (HSE) technology, Safety Instrumented Systems (SIS), and Electronic Device Description Language (EDDL) integration were demonstrated.
Fieldbus Foundation also held a briefing and reception for the German trade press on Tuesday, April 25. Dr. Gunther Kegel, chairman of the foundation's Europe, Middle East, and Africa (EMEA) Executive Advisory Council (EAC), updated attendees on recent fieldbus technology developments. He also discussed EMEA marketing activities and German end-user initiatives. The event gave trade press representatives the opportunity to meet key executives involved with fieldbus marketing activities in the region and talk with EMEA EAC members.
A panel discussion, "The Trends and Field Service ConfigurationEDDL Gains Support of Industrial Consortium," on April 25 included representatives from the organizations that form the EDDL Cooperation Team (Fieldbus Foundation, HART Communication Foundation, Profibus Nutzerorganisation e.V., and OPC Foundation). They discussed issues and answered questions from panel moderator David Humphries, ARC, and an audience of more than 50.

Grounding, shielding focus of Fieldbus Foundation/NAMUR effort
Fieldbus Foundation and Working Group 2.6 "Fieldbus" of NAMUR, the German-based, international process industries' end-user group, have formed a liaison to focus on "grounding and shielding" and "device diagnostics profiles." Both have identified these two key issues as areas requiring clarification and guidance, particularly for end-users in EMEA-area process industries.
As FOUNDATION fieldbus continues to be adopted globally, Fieldbus Foundation wants to ensure that the technology delivers required capabilities and functionalities. It works with end users, systems integrators, and engineering contractors through its End User Council and technical working groups to address the needs and requirements of end-user groups. Representatives from key member companies work with the foundation's technical staff and end-user representatives to find solutions to implementation issues raised by end-user groups.
A collaborative working group, led by Stephen Mitschke, manager of fieldbus products, Fieldbus Foundation, will compile a "best practices" guide to help end users make informed decisions about grounding and shielding a fieldbus network. The complex issue involves varying solutions supported by numerous guides, standards, and industries. An optimum solution depends upon many factors, including nature and location of the application. The new Fieldbus Foundation guide seeks to comply with the NAMUR Working Group 2.6 "Fieldbus" NA114 guideline, currently being developed, and international practices and options for grounding and shielding of fieldbus systems.
A second group, also led by Mitschke, will investigate the portfolio of self-checks and diagnostics for field devices. The initiative intends to ensure that FOUNDATION fieldbus devices are consistent with NAMUR Working Group 2.6 "Fieldbus" NE107 guideline that requires devices deliver diagnostics that ensure optimum plant efficiencies.
Praising the effort, Marc Van Pelt, Vice President of the Fieldbus Foundation's EMEA Operations, said, "Fieldbus technology is taking a strong foothold in Germany and across the EMEA region. As one of the cornerstone activities to which the Fieldbus Foundation's EMEA Executive Advisory Council is committed, the cooperation between the Fieldbus Foundation and end-user organizations such as NAMUR, represented by the NAMUR Working Group 2.6 "Fieldbus," is a vital step and allows for a greater understanding of their needs and requirements and will further the rapid adoption that is taking place. This ensures the continued deliverance of sound technical capabilities and functionalities and enhances the benefits achievable by implementers of FOUNDATION fieldbus."

Fieldbus Foundation is supporting ISA committee efforts to create a harmonized version of the International Electrotechnical Commission (IEC) 61804-3 international standard on Electronic Device Description Language (EDDL). ISA SP104 will republish the IEC standard as an American National Standards Institute (ANSI) standard.
EDDL is a text-based language for describing the digital communication characteristics of intelligent devices and equipment parameters in an operating system (OS) and human machine interface (HMI)-neutral environment. Using EDDL, a host system manufacturer can create one engineering environment and eliminate the need for custom software drivers for each device type.
ISA SP104 will create a North American national standard adopting the generic language specified by IEC 61804 to describe the properties of automation system components. The language is capable of describing device parameters and their dependencies, device functions, graphical representations, and interactions with control devices.
Fieldbus Foundation vice president of standards, Martin Zielinski, said, "End users are continually asking for better integration, interoperability, and even greater ease of use. In doing so, robust implementation must also be a number one priority. The foundation is focusing its resources on enhancement and standardization of EDDL. We are collaborating with the HART Communication Foundation, Profibus Nutzerorganisation e.V., OPC Foundation, and the IEC to speed enhancement and standardization of this established technology toward the goal of an ever-strengthening user interface. The objective is to increase interoperability by enhancing EDDL to improve device integration and ease of use, independent of the manufacturer."
Said Terry Blevins, committee chairman, "The SP104 committee will create a standard that adopts the IEC 61804 Electronic Device Description Language (EDDL). Modern control systems support advanced visualization of intelligent devices that are documented using EDDL."
Ian Verhappen, ISA vice president of standards and practices, added, "ISA, as a global standards organization, is working with IEC in a leadership capacity to develop this standard. It is important that this committee will harmonize its work with that of IEC SC65C WG7."
In 2003, Fieldbus Foundation, HART Communication Foundation, and Profibus Nutzerorganisation e.V. formed a cooperative joint working group to extend the capabilities of EDD technology. It developed extensions enabling robust organization and graphical visualization of device data, and providing support for persistent data storage. The extensions were made available to all three organizations to integrate within their respective control network protocols.
Device developers implementing EDDL do not need to design and program a graphic display system to run under a variety of platforms and environments. Instead, they can use the common graphic display capabilities provided by the standard. Since many host systems already have EDDL-based graphic display systems, devices using extended EDDL have a common look and feel with the existing devices. This permits uniform integration, configuration/setup, operation, and diagnostics/maintenance, important factors in an interoperable, multi-vendor environment.
EDDL's operating system and platform independence also eliminates the need for "plug-in" executable code that is costly to develop and can jeopardize the host's control over the HMI and operating environment. Enhanced EDDL follows the same proven test and registration procedures and revision control policies as EDDL.
In addition, EDDL enables end users to achieve unsurpassed levels of interoperability and device integration. It provides the freedom to choose "best-in-class" automation products from multiple suppliers, delivers the power to integrate devices to achieve optimum control strategies, and allows easy and efficient system upgrades.

Fieldbus Foundation launched a major demonstration project supporting implementation of FOUNDATION fieldbus Safety Instrumented Systems (SIS) technology with a kick-off meeting April 5-7 at Shell Global Solutions in Amsterdam, Netherlands. Leading process instrumentation end users and suppliers attended.
FOUNDATION fieldbus, with its distributed function blocks and open communications protocol, provides an ideal platform for advancing standards-based Safety Instrumented Systems. Fieldbus Foundation developed SIS specifications and guidelines in cooperation with leading end users, controls manufacturers, and safety experts.
The end-user demonstration, to be conducted at the Shell facility in Amsterdam, will promote adoption of the foundation's SIS technology in the process industries. The project will include development of SIS best practices and guidelines, training, and test tools, and a field demonstration of compliant safety instruments, logic solvers, and related equipment.
Companies participating in the demonstration working group include: ABB, BIFFI, BP, Chevron, Cooper Crouse-Hinds, DuPont, Emerson Process Management, Endress+Hauser, ExxonMobil, Fieldbus Diagnostics, HIMA, Hirshmann, Honeywell, Invensys, Magnetrol, Metso Automation, Moore Industries, MTL, Pepperl+Fuchs, Saudi Aramco, Shell Global Solutions, Smar, Softing, TopWorx, TÜV Rheinland, Westlock Controls/Tyco, and Yokogawa.
Said David A. Glanzer, Fieldbus Foundation director of technology development, "The foundation's SIS technology will enable end users to realize significant reductions in their total cost of ownership by extending FOUNDATION fieldbus benefits into plant safety systems. Major automation suppliers support SIS technology because they can market open, interoperable fieldbus devices instead of being limited to proprietary system platforms. End users support SIS because they can now choose 'best-in-class' SIS devices from the suppliers of their choice, just like they enjoy today for non-SIS devices."
Glanzer continued, "In addition, controls manufacturers implementing SIS can comply with recognized international standards. The foundation's SIS protocol meets the rigorous requirements of the IEC 61508 standard for functional safety of electrical, electronic, and programmable electronic safety-related systems, up to and including Safety Integrity Level 3. TÜV Rheinland Industrie Service GmbH, a global, independent, and accredited testing agency, granted the Protocol Type Approval last year."
With SIS products, end users can build systems according to the IEC 61511 standard covering SIS functional safety in the process industries. (IEC 61511 is also available as ANSI/ISA-84.00.01-2004 standard.) End users can benefit from the diagnostics available with FOUNDATION fieldbus, while maintaining the protection of a SIL3 environment. No changes were required to the existing FOUNDATION fieldbus H1 protocol to add the safety instrumented systems protocol extensions.
The Fieldbus Foundation's board of directors approved the SIS specification development project in October 2002. The project development team achieved its first major milestone at the end of 2003 with TÜV approval of the overall system concept. In October 2004, the Fieldbus Foundation announced completion of Draft Preliminary Specifications for the SIS development. During 2005, laboratory tests validating the specifications were successfully completed at R&M Industrieservice, an independent consultancy based in Frankfurt. Final Protocol Type Approval for SIS was granted by TÜV at the end of 2005.

The new CSPC (CNOOC and Shell Petrochemicals Co. Ltd.) petrochemical complex at Nanhai in southern China is one of the world's largest FOUNDATION fieldbus projects for the process industries. The installation includes 3,000 FOUNDATION fieldbus segments and 16,000 fieldbus devices. Implemented with the Yokogawa Vigilant Plant Concept, the site has nine Yokogawa Centum CS3000 systems with 200,000 tags in three control centers.
Johan Veerman, principal instrument and process control engineer at CSPC, said, "FOUNDATION fieldbus was the obvious choice for communications. In today's world, it's essential to have networks that integrate with each otherand to utilize the information flowing through them. Process instrumentation is being increasingly field networked to deal with the huge quantities of field data. Compared to conventional 4-20 mA systems, field networks are more flexible in terms of wiring, information flow, maintenance, and so on. FOUNDATION fieldbus doesn't just reduce the cost of wiring. It also transmits a lot of information in an intelligent way, and that makes it possible to do remote monitoring, real-time self-diagnostics, and predictive maintenance of field devices, as well as
Veerman indicated that proactive maintenance was a key design criterion on the CSPC project. "I was looking for a system that would enable proactive maintenance," he said. "One tool that can do this is Yokogawa's Plant Resource Manager (PRM), a real-time device and advanced diagnostics software package."

A major energy producer on the island of Trinidad was ready to start-up one of the world's largest gas liquefaction trains, but before it could do so it needed to upgrade the FOUNDATION fieldbus skills of its service personnel.
Vaughan Callender, business development manager for Process Systems Limited (PSL), was in a quandary because sending the technicians out of the country for training was not practical. Instead, he contacted the Fieldbus Center at Lee College and asked: "Could the Center customize a hands-on FOUNDATION fieldbus instructional course for the LNG plant, ship the necessary equipment, and start the training in less than two weeks? Despite the tight schedule, the Center's experienced staff was ready to meet Callender's needs.
Fieldbus Center, a National Science Foundation (NSF)-recognized and funded institution in Baytown, TX, provides advanced technology education and applied research assistance in the area of digital instrumentation and control network technology. Along with other key facilities, it offers Fieldbus Foundation-certified instruction. The courses deliver comprehensive FOUNDATION fieldbus training to students with diverse training needs and experience levels.
The Center is recognized for its realistic, "hands-on" approach to FOUNDATION fieldbus training. Its training and research facilities closely mirror the actual work environment of those involved in plant operation and instrument maintenance, particularly in the oil and gas and petrochemical industries.
The certified training courses teach students how to ensure full interoperability of devices from various vendors and the important considerations for maintaining fieldbus installations. The facility is a source of non-vendor-specific training demonstrating the full capabilities of FOUNDATION fieldbus and offers customized courses to help end users make the most of the technology while integrating or replacing existing legacy systems.
Three weeks after receiving Callender's request, Chuck Carter, Fieldbus Center director, was back in Texas, mission completed. The comprehensive instructional courses had been presented to combined groups of plant technicians, engineers, supervisors, and designers. Carter identified key factors that lead to the training success:
Based on the success of the initial training, the Trinidad technicians are looking forward to a set of courses this summer to cover advanced topics. The lesson for end users: FOUNDATION fieldbus training can be tailored to meet individual needs-no matter how demanding the circumstances!

MooreHawke's Trunkguard TG300 Series device couplers are designed and approved for use in Zones 1 and 2 with flameproof Exd devices. Each device coupler channel can be manually de-energized using a key-operated magnetic interlock, allowing individual fieldbus devices to be disconnected from the fieldbus segment without de-powering the entire segment, even in Zone 1 areas. The device coupler's LEDs show the current state of each channel (Normal, Fault, or De-Energized).
Available in a 4-spur configuration, the TG300 is reportedly the first solution providing fully automatic segment termination. The patented technology prevents fieldbus segment failure from under- or over-termination, a major problem in fieldbus startups. Featuring short circuit protection on detection of excess current on a spur, the TG300 reacts immediately to switch spur current to a nominal trickle-level, rather than limiting the fault current to a fixed (and always higher) level. With removal of the short, the spur is automatically reconnected to the fieldbus segment. Other features include diagnostic LEDs; and ready-to-install, field-mount packages complete with cable glands or quick-connect plugs.

A new series of High Speed Ethernet (HSE) controllers are the latest addition to Smar's System302 enterprise automation solution. These advanced devices offer enhanced connectivity and increased control capabilities due largely to the FOUNDATION fieldbus function block programming language.
This comprehensive series shares very important functionalities. All are connected to HSE for supervision and horizontal control, and each model has specific field-level network connections (FOUNDATION fieldbus H1, Profibus DP, DeviceNet, AS-I, and Modbus). The controllers can also access conventional signals from a variety of discrete and analog I/O cards.
The key enabler of FOUNDATION fieldbus control is the improved flexibility achieved via Flexible Function Blocks (FFBs) wrapping IEC 61131-3 programming languages. This structure supports the use of several communication technologies and conventional signaling in a single, integrated, and transparent environment for engineering, operation, and maintenance.
Although implementation of FOUNDATION fieldbus H1 (31.25 kbit/s) was a big step, broader benefits are achieved with a digital architecture using HSE as the core communication backbone of control systems, as Smar's System302 demonstrates.

Softing's flexible, embedded solution to fieldbus integration provides a fast, cost effective alternative to classic stack integration.
The investment needed to integrate a FOUNDATION fieldbus protocol stack into a process measurement device, and accompanying hardware redesign costs, often are not in line with a device manufacturer's forecasted ROI for the installation. Now, however, there is another option. Suppliers can enter the fieldbus market by implementing the Softing alternative.
The new Fieldbus Kit provides an intrinsically safe board with everything needed for FOUNDATION fieldbus H1 functionality. The electrical interface to the existing field device is realized via UART, I²C, or SPI. In addition, use of digital and analog inputs and outputs is flexible. Ready-made templates make the communication and configuration software easy and fast to customize to provide device-specific features.
Softing's approach is said to be especially simple for manufacturers of HART devices. The templates convert universal and common-practice HART commands to FOUNDATION fieldbus H1 commands. Device-specific commands are also taken into account. The board's intrinsically safe pre-certification make it usable in EEx ia area 1 (I.S. Division 1) without additional effort, resulting in a low-cost, quick-to-market means for HART device manufacturers to get into the FOUNDATION fieldbus market.

Turck's range of Fieldbus Intrinsically Safe Concept (FISCO) products supports different installation concepts in intrinsically safe environments. Use of a segment structure has become widely accepted. Through the use of multi-barriers, a bus segment can be created for the explosion hazardous area with the same segment structure as for the non-intrinsically safe area.
According to Turck, its MBD- -T415/Ex is the most advanced multi-barrier concept developed. The multi-barrier enables Exi drop lines up to 120 m long to allow spatially separated devices to be connected to an Exi star point. To prevent compensation currents caused by potential differences, individual Exi drop lines of the MBD- -T415/Ex are galvanically isolated from each other.
Galvanic isolation is important to signaling in the explosion hazardous area. The multi-barrier provides four intrinsically safe and galvanically isolated outputs. Full galvanic isolation is provided between the trunk line and the output circuits, and between the four output circuits themselves. This approach ensures the galvanic isolation required by industry for intrinsically safe circuits, particularly for zone 0. However, it does not exclude the possibility that any modification may influence the physical layer of the fieldbus with all the previously mentioned effects. Double galvanic isolation prevents any future unexpected problems, since faults may occur years after commissioning.
The multi-barrier is said to demonstrate Turck's pledge and philosophy-the development and supply of automation products fit for industrial requirements. Turck emphasizes device safety, particularly with products used for the explosion hazardous area. Complete galvanic isolation enables Turck to ensure customers of a high level of operational reliability.
