Fieldbus Ready to bring Real Benefits? - Oliver Jenkins - To date, major promoters of Fieldbus technology have focused on capital investment savings, since this has enabled easy justification of Fieldbus use on greenfield projects. But the early adopters of Fieldbus technology have found that once the initial challenges are overcome, the real benefit is achieved in mill run time, improved production efficiency, rapid production demand changes, flexible control strategy management, information flow, control data integrity, troubleshooting and device performance.
The Time is Right to Consider Fieldbus - A field bus (of one type or another) can be found across the whole plant structure. From Ethernet, through industrial LAN to control networks and discrete devices, it can bring a broad range of generic advantages. Field buses can also bring significant benefits to manufacturing systems in process control.
Control Valve Experience with FF Technology - at major Chinese petrochemical plant CSPC, a joint venture between the China National Offshore Oil Corporation (CNOOC) and Shell, is one of the largest petrochemical projects launched in the world in recent years. When production started in Nanhai early in 2006, the project was the biggest installation utilizing Foundation Fieldbus (FF) technology in process control and field instrumentation. The main reason for FF technology to be selected for the CSPC Nanhai project was its ability to provide a proactive approach to instrument maintenance. This is due to the fact that FF allows much more data to be transferred between field instruments and the host system compared with HART technology, for example. FF devices transmit information about an instrument’s condition before it actually needs maintenance or, obviously, when an instrument has an actual problem, as well as providing detailed diagnostic information about the nature of the problem. CSPC’s petrochemical plant is an early and successful example of adaptation to a new technology. CSPC uses diagnostic information from the intelligent FF valve controllers daily.

Digital technology enables new innovative and more powerful devices, wider measurement range, elimination of range mismatch, and access to more information. Overall, use of digital technology can reduce automation project costs by as much as 30 percent as well as providing a two percent operational improvement. This article explores considerations to be made in selection of bus technology for optimal digital plant architecture - from Emerson Process Management.
Case for Using FOUNDATION Technology - Modern DCS
systems are major distributed networks with multiple data paths, which, in the
interests of security and the highest plant availability, are almost always
duplicated and made redundant. This article describes how FOUNDATION fieldbus
systems can now incorporate redundancy and fault-tolerance right down to the H1
field layer. The major impact is on project ROI and plant revenues, and only
FOUNDATION technology can offer this level of security and benefit to the plant
operator - From the Fieldbus Report and MooreHawke Fieldbus.
Prepare for Tomorrow's Digital Plant - Ubiquitous and Cheap Data will Transform how an Enterprise Operates - Ian Verhappen - Rethink Applications - As sensors become more rugged, reliable, smarter and smaller it becomes possible to embed them on the surface of vessels much like is being done today with skin thermocouples on boiler furnace tubes. In the near future, such sensors will be available to measure, e.g., pressure, strain and corrosion. There even will be miniature analysers. A wireless gateway installed through a nozzle in a vessel will eliminate the need for any wires or connections inside the vessel itself. A few years from now a reactor may boast IP-enabled sensors surface-mounted on its baffles. Pressure, temperature and other sensors, each about the size of a dime, will create a complete vessel profile. Their data will allow us to operate the reactor much closer to optimum conditions, resulting in higher yield at lower overall risk. In addition, we'll be able to detect hot spots, build-up, fluid mal-distribution, localised corrosion and much more -- enabling much earlier identification of abnormal situations. The possibilities for integrated sensors will be limited only by our imagination. From Industrial Automation Networks and www.chemicalprocessing.com.
OpEx Data to Knowledge - and Profits - Ian Verhappen - There is more data generated by modern control systems in a day than was generated in a year just decades ago, yet the same control systems are unable to take full advantage of it. Data without relevant context has negative value and must be integrated with other data from higher level systems to be useful. This paper discusses how data integration across systems and organizations converts data into knowledge and knowledge leads to profits.
Fieldbus End User Adoption Trends Show Growing Acceptance- ARC Insight Report
Physical Layer Diagnostics reduces Downtime - Phil Saward (MTL-UK) - Hand-held test tools have been used routinely on the world's major fieldbus installations to speed the installation process by diagnosing wiring errors prior to start-up. In response to enduser feedback, recent enhancements have delivered better features such as noise measurement in multiple frequency bands and the ability to store field measurements before downloading them in the maintenance shop. Now, with the advent of continuous, on-line monitoring of the fieldbus physical layer, diagnostic information can be integrated into the asset and alarm management environments of today's fieldbus control systems. The paper will describe how the use of Foundation fieldbus as the protocol for communicating diagnostic information delivers an open architecture that is independent of control system choice. The key benefits of physical layer diagnostics will be explained, such as the ability to detect deterioration of segment performance before it affects the process, and improved use of maintenance resources during commissioning, hand-over and long-term operation - from the FFEUC Australia.
Maintaining Functional Value in FF Systems - Craig Webb (Honeywell) - A component of the justification for the use of FOUNDATION Fieldbus (FF) field devices has been the capability of those devices to provide comprehensive diagnostics. Delivering a useful result from these diagnostics has proven to require a structured approach to information collection, management and access. Raw device diagnostics must be processed to translate them into focussed, usable data that can be aligned to predefined maintenance actions and understood response urgencies. There is also benefit from the coupling of off-device assessments with on-device diagnostics to support functionally oriented process equipment performance assessment. The application of FF field devices in minimally manned and unmanned plant increases the reliance on FF dependability and the performance of diagnostic assessment. Performance of the device function must be sustained and rare failure events must be recognised and acted on with appropriate urgency to prevent production impact. Managed appropriately, diagnostics can greatly assist in the timely detection of the need for planned intervention. An approach for the management of device diagnostics for a range of FF device types, including transmitters and valve positioners, is discussed. This approach is currently used in the oil and gas industry in on-shoreplants and off-shore processing facilities - from the FFEUC Australia.
FOUNDATION Fieldbus Provides Automation Infrastructure for Operational Excellence - This ARC report highlights that End users are increasingly specifying automation products and services not based upon the level of technology they provide, but on the business value proposition. FOUNDATION Fieldbus technology should be looked at from the same point of view - from the Fieldbus Foundation.
Fieldbus Diagnostics latest Advancements Optimise Plant Asset Management - Stephen Mitschke - Since May 2006, the Fieldbus Foundation has been collaborating with NAMUR an international process industry end-user association based in Germany, on fieldbus performance enhancements such as device diagnostics, which both parties identified as requiring further clarification and guidance for the user community. A key objective of this collaborative effort is to unify the integration of fieldbus self-monitoring data to ensure the availability of valuable device diagnostic information to process plant personnel. Advancements in field diagnostics support a structured approach to asset management, which simplifies operators’ tasks and increases their confidence in utilizing equipment diagnostics and asset software - from the Fieldbus Foundation.

Justifying Fieldbus part 1 and part 2 - John Rezabek discusses a variety of ways to justify FF projects.
Fieldbus Justification Goes Beyond Total Cost of Ownership - Larry O'Brien - Fieldbus, as a digital replacement for 4-20 mA analog communications, is a simple concept, but it is significantly changing the way that users look at their processes and is providing a flood of information from the field about both the devices and their associated processes. Users should approach the process of choosing, implementing and using fieldbus in a way that will achieve successful and superior performance, reduced costs and operational excellence in the context of the enterprise’s business.

Advances in Fieldbus - Mike O’Neill of MooreHawke Fieldbus details of some of the awkward issues that fieldbus users might have to face including hazardous area choices, integrating devices into systems from different manufacturers, redundancy and fault-tolerance.
A Truly Redundant Wiring Solution for Foundation Fieldbus Segments - Mike O’Neill - A restricting factor in the uptake of FOUNDATION Fieldbus technology is that the physical layer used does not naturally allow for redundancy. Power supplies and interface packages can provide redundant connections to higher level networks, but all device communications within individual segments are absolutely dependent upon the performance and integrity of a single twisted-pair cable. This paper introduces a completely new and secure solution for fieldbus segment cabling which, when used in conjunction with redundant DCS system interfaces and redundant segment power supplies, is the final piece necessary to overcome objections to the reliability and vulnerability of fieldbus systems.

This emerging multidrop technology has been in development for many years and is finally gaining the recognition that it deserves. It provides many CAPEX and OPEX advantages including Control in the field, advanced diagnostics and predictive maintenance.
Field Device Networking: Extending Interoperability Beyond Devices-Larry O’Brien - Testing field devices may not be enough. Most interoperability problems happen when a device tries to communicate with a host system, but that can be addressed. As a company that is responsible for developing and maintaining communication protocols that are used by a large number of equipment manufacturers and end users, interoperability is one of our greatest concerns. Interoperability in this context is the idea that equipment from a variety of manufacturers can function in the same system without having to be coaxed or forced in the form of reconfiguration or other changes. A pressure sensor from company A should function on the same fieldbus segment as another unit from company D. To facilitate that objective, our organization, like other standards bodies, specifies how this communication takes place - from Control Engineering and the Fieldbus Foundation.

Fieldbus system, so it can be selected wisely and safely. From Smar Implementing Fieldbus Technology - Thorsten Krohn - This paper describes the fieldbus technology decision, the objectives for using fieldbus technology and the implementation strategy employed to realise the objectives.
Video - Understanding
the Use Case for Control
in the Field - Control in the field vs. control in the host:
Foundation fieldbus technology allows for both, so how do you choose? A new
study offers suggestions. If you are a Foundation fieldbus user, you know that
it supports control in the field (CIF), which allows a sensor and actuator to
form its own self-regulating PID loop, independent of the host control system.
While the effectiveness of the approach is well documented, what user cases make
it the most compelling for application? A new study has been completed by
Industrial Systems and Control, an engineering consulting group in Glasgow,
Scotland, that examines how CIF operates and where it is likely to offer the
greatest advantages over traditional host-based process control. In the video
Dr. Andy Clegg explains the parameters of the study, and the basic findings. His
report discusses how his team carried out the independent evaluation, and the
circumstances under which the high determinism of CIF can outperform
conventional loops driven by a PLC or DCS - from Control Engineering.
ARC Advisory Group: Control In The Field Enhances Process Integrity - In the white paper, titled "The Business Value Proposition of Control in the Field," ARC describes the incorporation of a function block structure and other supporting functions in Foundation fieldbus providing a complete automation infrastructure for operational excellence. Embedded control functionality in Foundation devices is one of the key enablers for achieving high availability control and a stepping-stone towards single-loop integrity - from the Fieldbus Foundation.
Fieldbus Enables Single-loop Integrity with "Control in the Field" - Single-loop integrity is the "good engineering practice" of designing process control loops (or control strategies) in such a way that if any element (e.g., transmitter, wire, power supply, controller, control valve, etc.) fails, there is minimal impact on production. Prior to the introduction of DCSs and PLCs single-loop integrity was a widely used good engineering practice in process plants around the globe and some end-users on the ISA SP50 digital fieldbus committee felt strongly about it. The vision of those forward-thinking committee members is now achievable using FOUNDATION fieldbus (FF) function blocks to implement control-in-the-field (CIF). - H. BU YU, SINOPEC Engineering Inc., China, and M. PELUSO, Emerson Process Management.
Foundation Fieldbus Parameter Search (βeta) - "Taking the Frustration out of Foundation" - As a systems engineer working primarily with Foundation Fieldbus devices, it was evident that there was a lack of information available describing the numerous parameters and functionality. ffsearch.org is a solution to this.

for Remote Operations Management -
One of the fastest growing segments in the world of process automation is remote
operations management. As the name implies, remote operations refers to the
management of automation assets that are located in or are dispersed throughout
remote geographic locations where it is difficult or impossible to send
personnel. This is not limited to remote offshore oil platforms and oil and gas
pipelines. It can also include tank farms and terminals, water and wastewater
treatment facilities, and any industry or application that requires remote
access to automation assets.
Video - The Unveiling of FOUNDATION for Remote Operations Management - The Fieldbus Foundation has unveiled its Foundation for Remote Operations Management (ROM) solution, a new technology initiative intended to develop a unified digital infrastructure for asset management in remote applications such as tank farms, terminals, pipelines, offshore platforms, and even OEM equipment skids. The technology enables fieldbus connectivity to remote I/O and the leading industrial wireless protocols, including WirelessHART and ISA 100.11a. It provides an interface to these wireless technologies and uses Electronic Device Description Language (EDDL) and function blocks to ensure interoperability with Foundation for ROM devices - from Control Engineering.

Installing Fieldbus in Real-Life Applications - Many automation engineers are coming face-to-face with real fieldbus applications for the first time. Fieldbus is a wonderful technology with many benefits, but fieldbus installation requires some additional considerations over and above normal 4-20mA projects. In this in-depth white paper, we discuss some of those issues, and show you how to deal with them.
Fieldbus Installation - Short-Circuiting Fieldbus Installation Problems - Tim Wilson and Jeff Marsh - Like other process industry operations, bio-fuel production plants seek state-of-the-art automation technology in order to reduce raw material costs, increase yields, comply with regulatory standards and maximize revenues. However, plant managers must ensure control systems provide reliable operation and a low cost of ownership over the life of installed assets. Although modern, fieldbus-based process control systems offer many operational benefits, ethanol producers need effective measures to protect the fieldbus physical layer against short circuits, improper termination and other problems that can adversely affect system performance and reliability. They also need solutions enabling a quick ramp-up from installation to operation of the control system in order to improve their time to market - from Control Global.

Fieldbus: Commissioning with Advanced Diagnostic Tools - Modern day fieldbus diagnostic tools – such as the Advanced Diagnostic Module for the FieldConnex® Power Hub – bring transparency to the fieldbus physical layer and communication. The module performs measurements such as supply voltage, load current, signal level, line noise or jitter. The module listens to the communication and distinguishes between segment and device information. Clear and concise displays within the Diagnostic Manager show readouts to the user – this brings transparency to a plant condition that seems ambiguous - from Pepperl+Fuchs.
Monitoring the Fieldbus Physical Layer - Commissioning the fieldbus with advanced diagnostic tools - What was unthinkable for point-to-point wiring, is affordable for the fieldbus: the new Advanced Diagnostic Module from Pepperl+Fuchs offers the measurement and monitoring of the physical fieldbus structure from the control station. Designed as a plug-in card for the modular power supply system Power Hub, the module gathers all the measurements of the fieldbus physical layer for all fieldbus segments and combines them at a single maintenance workstation online and in realtime. The fieldbus diagnosis provides transparency, and the measurability of the actually transferred signals gives installers and operators of process systems a more complete picture of the behavior of the fieldbus. This allows for otherwise often inexplicable behavior to be analyzed with precision. You can also measure and verify the reserve power available on the fieldbus - from Pepperl+Fuchs.
Advanced Diagnostics Self Validates Health of Fieldbus Networks - Wil Chin and Allen Avery - Diagnostic capabilities for Fieldbus networks have evolved significantly over the years. Rudimentary tests such as instrument elevated zero outputs and simple I/O health checks gave way to superior instrument and process diagnostics with the introduction of HART, which had its limitations due to bandwidth restrictions. The advent and acceptance of Fieldbus has in-creased the use of sophisticated sensor technology and process diagnostics. Until recently, it was cost prohibitive to monitor the health of the entire Fieldbus network. However, that has changed with the introduction of more sophisticated Fieldbus hardware and advanced diagnostic systems - from Pepperl+Fuchs.

10.13 Portable Tools Can Make Fieldbus Easier - Most people think of fieldbus as digital integration of field devices with process automation systems and that working with Fieldbus can only be accomplished with fixed assets (such as PCs) located in fixed locations, but there are also a number of portable tools available that can make specific fieldbus tasks a lot easier and help you get a better return on your fieldbus investment. There are some very good reasons for using portable tools and a wide range of products available with different functions and price levels. Here are some of the more compelling reasons to use portable tools, the different classes of tools, and some things the Fieldbus Foundation is doing to ensure that the products you purchase match their specifications.

Emerson Process Management Segment Design Tool for Physical and Electrical Design Verification - The Segment Design Tool is a Windows 2000/XP/Vista compatible program designed to provide a general guide for reducing the time required to engineer a FOUNDATION Fieldbus H1 segment of DeltaV systems, Ovation systems and 3420 Fieldbus Interface Modules. The Segment Design Tool checks the segment layout utilizing the FOUNDATION Fieldbus rules governing cable lengths, power consumption and proper segment termination. This tool now supports a variety of Intrinsically Safe concepts, including Entity, FISCO FNICO and High Power Trunk (HPT). Given that the tool results are based on ideal components, power and layout specification, the tool results only provide a general indication as to the expected performance of the segment; therefore; the PlantWeb Architecture components specifications and installation instructions will always take precedence.

The process involves the production of sodium benzoate, a food and beverage preservative, from toluene or methylbenzene. In particular, the article discusses how a new, FOUNDATION fieldbus-based control system met the need for improved safety and fault tolerance at the plant, and provided a solution for increased availability and reduced losses of raw materials and finished products - from the Fieldbus Foundation.
The World’s Largest Installation of Foundation Fieldbus at China’s Largest Petrochemical Complex - Mike Spear - Across the 10 plants and utilities there are over 48 000 control loops, with about 166 000 I/O tags and around 25 000 points hardwired to the automation system. There are 40 000 instruments and some 13 000 intelligent devices networked in the world’s largest Foundation Fieldbus installation. In total there are 2500 FF segments. Adrian Howell, SECCO’s process control manager, says that ‘while we knew that a fieldbus approach would save considerable amounts of cabling, a conservative approach was taken to the number of devices connected on each segment. Designs were limited to no more than 12 devices, and the average ended up as five devices per segment, where each segment varies between two to 11 devices - from the Fieldbus Foundation.
Power Plant sees Green with New Digital Bus System - John Blaney, Jim Murray, and Gary Tingley - Chasing advantages in design and construction savings, the utility wanted to incorporate digital bus technology in as many areas as possible. Both Foundation fieldbus and PROFIBUS are used significantly throughout the balance of plant systems. Another reason behind the decision was simply the opportunity to try new technology on a new plant since the technology has been proven in many other industries, just not in the power industry - From the ISA and InTech.
Foundation Technology: End User Perspective on Automation Infrastructure for Operational Excellence - Phil Stoor -Brunner Mond (UK), a major producer of sodium carbonate (soda ash) for the European market, decided to replace the outdated control system at its Northwich East plant in Cheshire, England, with the latest process automation technology. Brunner Mond sought a modern control system that would improve its operational efficiency, reduce plant maintenance costs, increase safety, and minimize unplanned shutdowns due to equipment failure. After considering various competitive approaches, Brunner Mond installed a FOUNDATION™ digital automation infrastructure. During the first phase of the DCS replacement, fieldbus technology was employed on two Solvay towers used to carbonate ammoniated brine to form sodium bicarbonate crystals. This project proved to be successful, and set the stage for implementation of additional fieldbus controls on Brunner Mond’s Northwich production operation.
Intelligence Moves Plant from Preventive to Predictive Maintenance - Laura Thomas, Jay Kalinowski, Curtis Cook and Lou Verduzco - Applying fieldbus technology to a water treatment plant requires a shift from traditional instrumentation and electrical design methods. OCWD made the decision to preselect a DCS, develop software and hardware standards, and have all systems developed using those standards. Before preselecting a DCS, OCWD decided to use Foundation fieldbus for instrumentation and DeviceNet for motor control centers and variable frequency drives. Classic I/O would serve as necessary. After a preselection process, OCWD selected Emerson Process Management's DeltaV system.- thanks to InTech

Five Critical Factors for Selecting Fieldbus Valve Manifolds - Enrico De Carolis - In today’s highly automated machines, fieldbus valve manifolds are replacing conventional hardwired solutions. They more easily perform vital functions by integrating communication interfaces to pneumatic valve manifolds with input/output (I/O) capabilities. This allows programmable logic controllers (PLCs) to more efficiently turn valves on and off and to channel I/O data from sensors, lights, relays, individual valves, or other I/O devices via various industrial networks. The resulting integrated control packages can also be optimized to allow diagnostic benefits not previously available. This paper presents controls engineers, specifiers, and buyers with new insights into five crucial factors they must consider before selecting pneumatic fieldbus valve manifolds — commissioning, distribution, modularity, diagnostics, and recovery — while also outlining some shortcomings of conventional approaches. Finally, it highlights new designs that offer substantial improvements in the application, performance, and maintenance of these valve manifolds from the end users’ and OEMs’ points of view - from Numatics, Inc.

The Electronic Device Description Language (EDDL) - 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. Just "heaps" of information here on the EDDL site!
EDDL Makes Device Setup Easy - Device setup (aka configuration or parameterization) can be carried out using a handheld communicator in the field, a laptop in the workshop, or from intelligent device management software as part of asset management solution. Electronic Device Description Language (EDDL) is the technology used by device manufacturers to define how the system shall display the device setup parameters to the technician. EDDL makes setup of intelligent devices easier thanks to user guidance such as wizards, illustrative images, and help text, and provides unparalleled consistency of use.
Device Revision and Lifecycle Management Guide - How to keep systems up to date and compatible with new devices using EDDL - DDL (IEC 61804-3) is a device integration technology created as a solution to the device revision problem. EDDL makes managing devices of different types and versions easier. EDDL2 is a file that is loaded onto the computer or handheld field communicator. There is no EDDL inside the device3 itself. Thus there is no such thing as an "EDDL device" or a "non-EDDL device". Devices are HART, FOUNDATION fieldbus, PROFIBUS, and WirelessHART devices, and these protocols support EDDL.
EDDL Makes Device Diagnostics Easy - Device diagnostics can be carried out using a handheld communicator in the field, a laptop in the workshop, or from intelligent device management software as part of asset management solution, either from a dedicated maintenance console or integrated in the operator console (see separate white paper on integrated operation). Electronic Device Description Language (EDDL) is the technology used by device manufacturers to control how the device diagnostics is displayed to the technician. EDDL makes diagnostics of smart transmitters and other intelligent devices easier thanks to user guidance such as wizards and help, and provides unparalleled consistency of use.
EDDL Makes Calibration Easy - Calibration can be carried out using a handheld communicator in the field, a laptop in the workshop, or from intelligent device management software as part of asset management solution, either in a dedicated maintenance console or integrated in the operator console (see separate white paper on integrated operation). Electronic Device Description Language (EDDL) is the technology used by device manufacturers to control how the device diagnostics is displayed to the technician. EDDL makes calibration of intelligent devices easier thanks to user guidance such as wizards and help, and unparalleled consistency of use.
Commentary on FDT/DTM vs. EDDL - This commentary is highlighting some observations in the WIB test report T 2768 X 07 "FDT/DTM or EDDL for asset management using FF technology" dated November 2007, usually left out when referenced by the FDT Group. It also explains some misconceptions, probably due to only one device having been verified.
EDDL makes Working in the Field Easy - Field communicators have existed for as long as intelligent devices. The early problem of plants having to grapple with many different communicators was solved already in the mid nineties by standard protocols like HART and Foundation fieldbus together with the Electronic Device Description Language (EDDL, formerly just known as DDL), an integral part of both technologies. A single universal field communicator supports all instruments, an arsenal of many communicators is no longer required.
Consistent Look & Feel - EDDL makes Intelligent Device Management Software Humane - When devices from multiple vendors were first integrated using bus technologies there were difficulties accessing all device features and there were difficulties to make full use of the features that could be accessed. Many plants were not able to use the device management software part of their asset management solutions to its full potential. A new concept was required to achieve even greater results with digital bus technologies. The new innovative solution to the problem was enhancements to an old technology that has been an unnoticed part of leading digital bus technologies for over fifteen years. This international standard, called EDDL (IEC 61804-3), with enhancements, makes bus technologies come alive and easy to use in exactly the same way the World Wide Web made the old Internet come alive and so easy that anyone could use it. Systems based on EDDL with enhancements now make maintaining intelligent devices very much easier for technicians and enable digital bus technologies to be fully utilized to derive greater result for the plant and there are no other means to achieve the same result. This article will explain how consistent look & feel is achieved in spite of each device manufacturer independently deciding display content any way they like.
EDDL Questions Answered - 20 FAQ questions about EDDL answered.
Keeping Systems and Communicators Up-to-date using EDDL - Technical Paper - Christian Diedrich, Jonas Berge, Ludwig Winkel and Terry Blevins - Modern control systems as well as Device Management software and field communicators use electronic device descriptions, EDD, to define the interface and supported interactions with field devices for configuration, diagnostics and calibration. Over the long life of plants, new device types and versions keep getting added as part of replacements and modifications. Thus, these systems and maintenance tools must accommodate many new types, each generation also providing new features. For example, more than 1000 EDD’s are currently available from 85 different vendors. Also, many manufacturers are currently updating their device descriptions to take advantage of the visual enhancements recently introduced into the IEC61804-3 standard, Electronic Device Description Language (EDDL). Therefore, to achieve the best results, the latest electronic device descriptions should be used with your HART devices and Profibus and Foundation fieldbus devices.
The following Foundation fieldbus technical information is from
Digital Fieldbus Installations Use EDDL Technology for Simplicity with Advanced, Full Functionality- EDDL technology enables a Host System manufacturer to create a single engineering environment that can support any device, from any supplier, using any communications protocol, without the need for custom software drivers for each device type.
EDDL: Marching into Mainstream - Jonas Berge - Simple smart pressure and temperature measurement transmitters could be configured without need for graphics. However, more sophisticated (complex) devices such as valve positioners, variable speed drives, machinery health monitors, and radar level transmitters now common in process industry plants require advanced graphical setup and diagnostics. By upgrading software to the new enhancements of the international standard IEC 61804, plant personnel can make their devices, both old and new, simple and advanced, easier to use than ever before. Similarly, predictive diagnostics can be better integrated into daily work practices by displaying them to the right persons. This is achieved without making system management more difficult with respect to staying current with new devices and Windows versions. This article recommends a best practice for device integration outlined in the NAMUR NE 105 recommendation by upgrading to a single standard: IEC 61804-3.
Temperature Transmitters Warming Up to EDDL - Jonas Berge - Enhancements to the EDDL IEC 61804-3 standards have improved advanced setup and diagnosis of high-end temperature transmitters. Temperature transmitters communicate digitally using protocols such as HART, Foundation fieldbus, and WirelessHART. Supporting this mix of transmitters can be a challenge. However, modern temperature transmitters diagnose themselves, the sensor wiring, and the temperature element. This allows for more effective maintenance schemes that help keep the loop and plant running with minimum downtime.
Pressure Transmitters: EDDL Equals "Easy" - Dale Perry/Jonas Berge - EDDL technology makes sophisticated pressure transmitters easier to use. within the last few years many specialised pressure transmitters have been introduced. These transmitters specialise in areas such as DP Flow, Mass Flow, Safety Certified, and Diagnostics. The value of specialised transmitters has been demonstrated to increase quality, throughput, or uptime. Any added complexity of maintaining these transmitters through their life cycle, installation, start-up, routine maintenance or emergency maintenance could be a challenge to plants.
OPC made Easy - EDDL can save numerous man-hours of OPC server configuration and speed up project completion - Jonas Berge - OPC is an o p e n standard me t h o d for transferring data between software applications, used for example to obtain data from devices. Once an OPC server is configured, external software in HMI clients and other users can easily access the wealth of detailed diagnostics and information in hundreds or thousands of intelligent devices around the plant. Configuring OPC clients is easy: just point and click on data in the OPC server. To enable this, the OPC server must first be configured. Electronic device description language (EDDL) makes this easy.
EDDL: Unlocking Device Information - Jonas Berge explains how enhanced Electronics Device Description Language (EDDL) simplifies device configuration, calibration and diagnosis, and brings benefits to the bottom line.
EDDL allows Interoperability for Devices to Constantly Gather Information - No matter what control system a plant is using, it is now easier for users to choose best-in-class instruments for their networks. The technology that allows this is Electronic Device Description Language (EDDL). From the ISA and InTech.
1.14 The Digital Drive - Jonas Berge explains how variable speed drives can become an integral part of the digital plant architecture. The final control element that first comes to mind for process applications is the control valve, but variable speed drives (VSD) also variously referred to as a variable frequency drives (VFD), adjustable frequency drives, or frequency converters are also used as final elements in closed loop flow or pressure control. When it comes to set up, the sheer amount of configuration options available in a variable speed drive can seem overwhelming to technicians who have to commission them. A drive can have hundreds of parameters to customize AC motor controls for different applications. Most AC drives also have useful diagnostics about the motor and drive system and some even have predictive diagnostics. To help technicians more easily setup applications and diagnose problems, drive manufacturers now use electronic device description language (EDDL) to make drives easy to setup and diagnose by defining how the drives are displayed in the system. Bus technology and EDDL provide the ability to integrate instrumentation and controls with electrical and switchgear, enabling plants to freely select control system and electrical system independently, yet enjoy the ease of use as a result of tight integration - from Control Engineering Asia.

Trim - EDDL technology makes calibration easier thanks to user
guidance such as wizards as well as know-how made available from the device
manufacturer's experts. The result is lower cost of maintenance, and better
Intelligent Device Management Tutorial: Calibration - In the early days of smart transmitters the concept of remote range setting ("remote calibration") and re-ranging without applying input was revolutionary. It took years of education to be accepted and understood. Calibration can be carried out using a handheld communicator in the field, a laptop in the workshop, or from intelligent device management software as part of an asset management solution. Electronic Device Description Language (EDDL) is the technology used by device manufacturers to define how the system shall display the device information and functions to the technician. EDDL makes calibration of smart transmitters and other intelligent devices easier thanks to user guidance such as wizards and help, and unparalleled consistency of use.
EDDL Solution for Field Tasks - Field communicators have existed for as long as intelligent devices. The early problem of plants having to grapple with many different communicators was solved already in the mid nineties by standard protocols like HART and Foundation fieldbus together with the Electronic Device Description Language (EDDL, formerly just known as DDL), an integral part of both technologies. A single universal field communicator supports all instruments, an arsenal of many communicators is no longer required.Use of Windows software from the central control room has since become possible thanks to multiplexers and digital communication interfaces embedded in control system I/O modules. These systems may access data in devices using HART, FOUNDATION fieldbus, PROFIBUS, WirelessHART, or a combination of two or more of these. Although many maintenance tasks can be done remotely from centrally located device management software part of Asset Management Solution (AMS), there are several other tasks that must still be carried out in the field right next to the device. Because of such field work, a compact field communicator is highly valued by maintenance technicians. A notebook computer is not ideal. EDDL is the only technology suitable for portable communicators because it works on embedded operating system used in such devices. IEC 61804-3 graphical enhancements the EDDL now make field communicators easier to use and powerful enough for complex devices.
Calibration Trim Wizard using EDDL - Narrated by Emerson's Harish Jayaraman this video shows how calibration trim is simplified by wizards from software or handheld communicator from different vendors using EDDL - from YouTube.

Field Device Technology (FDT) - Technical Description - FDT (Field Device Technology) is an interface specification for open data exchange between field devices and automation plants that is standardized by the international standards IEC 62453 and ISA103. In Field Device Technology, two terms are particularly important: DTM (Device Type Manager, or “device driver”) and FDT Frame Application. Both are software components whose functions can only be performed together. FDT provides a common platform for data exchange for all available device drivers (DTMs) produced under this standard. This allows complete and functional access across different network hierarchies to all device functions for devices made available by the DTM. With this capability, every device can be confi gured, serviced, and maintained via one basically standardized user interface – independent of manufacturer, device type or communication protocol. Information from an automation plant (especially communications or field devices) is needed throughout the entire life cycle of a system or application. FDT provides support with versatile and extremely helpful functions as early as planning and project engineering, then during installation and commissioning, and finally during operation and service.
FDT Movie - Are you looking for an easy to understand introduction to FDT and its benefits? Have you always thought it would be nice to have something else to explain FDT than just a normal PowerPoint presentation?
Field Device Tool (FDT) Technology, What is It? - FDT (Field Device Tool) technology standardizes the communication interface between field devices and systems.The key feature is its independence from the communication protocol and the software environment of either the device or the host system. FDT allows any device to be accessed from any host through any protocol.
FDT Technology Benefits - User and Vendor benefits.
FDT Introduction Brochure - FDT is an open technology that enables users to easily access and extract intelligent information from their automation products.
Why FDT Technology - A useful user brochure.
ISA103 Field Device Tool Interface - The FDT Group is dedicated to providing Open Access to Device Intelligence for the automation industry. Like other information technologies, the FDT Group is looking forward to the evolution of the FDT specification in response to the feedback from end users. The ISA103 Field Device Tool Interface Committee was formed in 2006 to consider the adoption of IEC 62453 Standard as an ISA Standard. In May 2009, the FDT Group achieved a significant milestone when the IEC 62453 Standard was unanimously accepted by the international standardization community.
Which is Better? - Currently, two technologies are available for doing so: DD (Device Descriptions) and its enhanced form eEDDL (enhanced Electronic Device Description Language), and FDT (Field Device Tool). In order to assess which approach delivers the best results, it was necessary to test and compare their performance in practice.
Value Proposition for FDT Technology Continues to Increase - Wil Chin and Paul Miller - Even after achieving a significant milestone in 2009, IEC 62453 approval, the FDT Group’s efforts continues. Under its new leadership, the FDT Group continues to move forward at an increasingly faster pace as more suppliers and users alike embrace the technology.
FDT Technology—What Are DTMs? - Annie Sisson - It has been recognized time again that the ability to have open access to device intelligence is essential to enhanced reliability and reduced start-up times. In the area of industrial automation, FDT Technology provides this “open access” with a device type manager (DTM). With DTMs, users can configure device parameters, operate devices via a graphical interface and access advanced diagnostic information from any location - thanks to Control Global
FDT Open Access to Device Intelligence Unlocks Interoperability to Bridge Information Silos - The user benefits of truly open industrial device management continue to be an elusive goal in virtually every industry. For example, in the process industry, users have accepted that there will never be a single, standardized protocol for all applications. Other industries are suffering similar issues. If history is an indicator of the future, users will be working with multiple incompatible protocols for many years to come. Users continue to dream of the day when one can plug & play hardware and software seamlessly without a second thought regardless of industry, device, actuator, control system or application. FDT is making this closer to reality than anyone would have thought possible only a few years ago.
FDT - Technical Description - A comprehensive Technical Description.
Field Device Tool (FDT®) Technology for the Process Automation and Manufacturing Industries - What end users want is a standard interface that connects any automation system to any device, providing them with the freedom to choose the best device fit for their application, irrespective of supplier or communication protocol.
Human-Centered Design (HCD) in an FDT/DTM Environment - Tom Wallace - We Need a New Way to Interface With Field Devices That Increases Productivity, Reduces Training Needs, and Reduces Human Error - The process industry faces a perfect storm of factors that will change how we interact with field devices. Plants are becoming larger, more complex and subject to more regulation. Plants will have more devices, more different device types, and the devices themselves will be more complex. Also, devices and communication protocols are becoming more complex and capable. In addition, we're facing the loss of experienced workers with their replacements being less experienced and fewer in number. We face doing more work and more complex work with fewer and less experienced people. We need a new way to interface with field devices that increases productivity, reduces training needs, and reduces human error. This new way will use human-centered design (HCD) - from Control Global.
