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
Buses for Digital Plants - Digital
communications technology reduces wiring and improves end-to-end signal accuracy

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

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.

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.

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.

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.

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.

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

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 -

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.

A
Nuclear Perspective on Foundation Fieldbus Application
- This presentation covers the selection and reasons behind this
Foundation Fieldbus solution in the Duke Energy plant - Michael
H. Miller - from the Fieldbus Foundation.
Foundation
fieldbus has improved Safety and Availability of Chemical Additives Plant for
over 10 years - This article describes how FOUNDATION
fieldbus based control system was used to automate a chemical additives plant
operated by Wuhan Youji Industries Co., Ltd. in the People's Republic of China.
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

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.

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.

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.

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.

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.

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)
