HART Communication Covers the WorldBy Ron Helson, Executive Director, HART Communication Foundation
Today’s challenging global economic environ-ment continues to place more and more em-phasis on the need for cost-efficient process
and asset management improvements to keep pro-cess manufacturing facilities relevant, competitive and sustainable. The best response to this economic challenge is to look at your process control systems and installed assets in a totally different way.
For 20 years, the HART Communication Protocol has evolved and grown, establish-ing an infrastructure that offers a cost-effective, reliable, easy-to-use and low-risk field communication solution for process measurement, control and asset monitor-ing/management. This worldwide HART ecosystem now extends into wireless technology with WirelessHART providing new communi-cation paths for real-time process information, diagnostics and asset performance measures.
Wireless HART is Here and Ready for You!WirelessHART is the first simple, reliable and secure wireless communication standard for process monitoring and control applications (IEC 62591Ed. 1.0). WirelessHART builds on the proven HART Communication Protocol standard, providing the same rigorous, compliance-verified interoperability to meet your process automation
requirements. Plus, it is backward-compatible and future-proof with your existing HART devices and systems—protecting your investment and assuring that current and future devices will work together.
With WirelessHART, additional process and asset performance measurements can be installed for temporary (troubleshooting) or permanent applications with few or no wires – greatly reduc-
ing both installation cost and time. The cost savings are so dramatic that Wire-lessHART could be the solution to getting your projects approved because it uses so much of your existing infrastructure and, in most cases, can be installed with mini-mal process disruption.
HART and WirelessHART communication solu-tions can help you lower costs, improve operations and optimize assets. The articles in this edition will help you understand how and show you that there is no need to wait! HART Communication, both wired and wireless, will help you save money for your plant and your company now.
So if you’re looking to upgrade your plant for sustainable and globally competitive operation…for today and for the future…look to products and solutions based on the international standard – HART Communication – because HART covers the world of process automation.

From the inception of the HART Commu-nication Protocol, two of the technology’s critical capabilities have been interchange-
ability and interoperability. That is, any HART transmitter must work interchangeably in the same application with any other HART transmit-ter, regardless of manufacturer, and any HART transmitter must work with all other HART transmitters, again regardless of manufacturer. This has permitted the huge growth of the HART protocol—with now more than 30 million devices installed worldwide. With HART technology, you can have ten transmitters from Vendor X, add three from Vendor Y and expect that they will communicate the same way, operate the same way and use the same handheld communicator or PC program through a HART modem.
Because HART requires interchangeability, you can mix manufacturers and products in the same network. Controllers use the same commands with all devices. Standardized diagnostics are in every device. The same tool works with all manufactur-ers, and one EDD (Electronic Device Description) works on all EDD-enabled Hosts.
Interchangeability means that you have the freedom to use any revision of the protocol or of the device without mandatory upgrades of tools or applications.
IntEROpERaBIlItY MEans standaRdIzEd dIagnOstIcs.The HART Protocol has expanded and evolved over the past 20 years. HART 5, the most widely used version of the protocol, was released in 1989. In 2001, the HART Communication Foundation released HART 6, which was adopted by some, but not all, of the manufacturers of HART devices. In
2007, HART 7, which includes WirelessHART, was released, and was immediately adopted by vendors around the world. In 2010, the WirelessHART por-tion of HART 7 was approved as the first interna-tional standard for wireless communication for the process industries (IEC 62591).
HART has always been built upon standards. The IEC recognizes HART as part of its Industrial Communication Networks and Device Description Language (EDDL) standards. WirelessHART is built upon the IEEE 802.15.4 standard for low-power mesh radio networks.
Because of the huge installed base of HART wired transmitters and field devices, it is very well known that HART devices are all interchangeable and interoperable. They all are also backward-compatible. This means that while you can ADD features in subsequent revisions, you cannot re-move features or change the meaning of diagnos-tics or data from a previous revision. This commit-ment to backward-compatibility and protection of installed assets is what made possible the incred-ible adaptability of WirelessHART.
There are over 240 vendors who produce HART devices—transmitters, actuators, analyzers, valve positioners and other field devices. Because of the interoperability and interchangeability built into the HART specifications, some of these vendors are building devices on HART 5, some on HART 6, and many are upgrading to HART 7 and WirelessHART. These 240-plus vendors and the owners of the 30 million-plus installed HART devices form a robust ecosystem.
Honeywell Process Solutions has upgraded to HART 7 because of the new features available for wired HART devices. It has chosen to use wired HART because the Experion DCS auto-

matically takes the diagnostics and alternate PV information off the standard 4-20 mADC wiring. Honeywell has produced an adapter to provide older HART transmitters access to its One Wire-less plant infrastructure network. “Most of our devices are currently based on HART 6 and will support HART 7, says John Yingst, a Honeywell product manager. “Our Field Device Manager asset management software can currently con-� gure HART 7 devices with additional HART 7 support enhancements planned.”
Emerson Process Management was � rst to mar-ket with HART 7 and WirelessHART devices, and now has over a dozen devices including a gateway, network manager software, a WirelessHART adapter (called the THUM because of its shape), several wireless transmitters (pH, � ow, temperature, wet chemistry) and smart valve actuators that are wirelessly enabled using WirelessHART.
“We have a complete wireless portfolio,” says Bob Karschnia, Emerson’s vice president of wireless. “People are solving problems, not just collecting data. THUM adapters make additional data points available that would otherwise remain stranded and provides easy access to information that will enable improved performance. For example, standard Coriolis meters using 4-20mA output often need to be veri� ed to ensure accurate custody transfer and top � scal performance. A Smart Wireless THUM
adapter enables measurement veri� cation in an easy and scheduled way.”
ABB has also brought out a new suite of wire-less transmitters, including a WirelessHART adapter and a temperature transmitter that can be powered by a power-harvesting device instead of a battery. “While many WirelessHART devices are intended to be battery-powered, we believe that the majority of applications to retro� t existing HART transmitters need no batteries. We have therefore produced a simpler WirelessHART adapter that takes its power directly from the al-ready existing 4-20 mADC loop connection,” says ABB CTO Peter Terwiesch.

REGISTERING A HART DEVICEIn 2009, the HART Communication Foundation board of directors voted to require independent testing in order to register a HART device, wired or wireless. This testing is an addition to the testing required of the manufacturer prior to registration testing.
“To verify compliance with the HART Protocol Specifica-tion, wired and wireless devices that claim to be “HART Registered” must pass the HART Device Registration Program conducted by the Foundation,” says Foundation executive director Ron Helson. “HART registration is avail-able for all process measurement devices, interfaces such as modems, multiplexers and I/O systems, HART masters including systems and handhelds and Device Description (EDD)-enabled host applications.”
“100 percent verification tests are conducted to con-firm compliance to the HART Protocol standard,” says Ed Ladd, HART Communication Foundation director of
technology programs. “Running the tests ourselves and independently verifying that submitted devices meet the intent of the standard ensures interoperability—reduc-ing the risk of problems in the field.”
But before the Foundation gets the device to test, the man-ufacturer must do the testing itself—and provide the data to the Foundation, as well as a device for testing. The list of requirements is long, and the procedure is rigorous. “Both good and bad data are sent to see that the device responds appropriately,” Ladd says. “For example, test DLL 039 stress test involves two million messages. Devices have to interop-erate and be robust on the network,” Ladd continues. “To be ‘registered,’ a device can miss no more than 20 messages.”
Why the detail and rigor? “If you’re replacing a device at 2:00 a.m.,” Ladd says, “you need to know it’s going to com-municate—no matter who manufactured it. That’s what the registration process is all about.”

ABB is also proving that the vaunted interop-erability and interchangeability of the HART specification extends to WirelessHART. Instead of developing its own gateway, ABB is using one produced by Pepperl+Fuchs.
Gerrit Lohmann, Pepperl+Fuchs’ wireless product manager also points out that the exten-sion of HART to wireless also works in the other direction. “I feel that the interest in WirelessHART will also have a positive affect on wired HART multiplexers,” he says. “With all of the talk re-garding WirelessHART, people are rediscovering the benefits of HART. As the pressure continues to grow to optimize in a cost-effective manner, the stranded HART data contained in legacy instruments will be extracted via the customers’ existing hardware, through a HART multiplexer or by the lat-est WirelessHART solution.”
WirelessHART is giving companies that aren’t known as field device manufacturers the ability to provide key building blocks of the WirelessHART ecosystem. For example, Pepperl+Fuchs—long known as a networking company, but not as a process transmitter supplier—is supplying gate-ways both under its own brand and as a pri-vate label to other suppliers, as well as a Wire-lessHART adapter and a temperature converter that converts two temperature sensor values to WirelessHART.
Phoenix Contact (PC) is also producing a Wire-lessHART gateway. Ira Sharp, product marketing lead for wireless for Phoenix Contact, has some thoughts on the security of the WirelessHART network that is connected to his gateway. “Wire-lessHART uses 128-bit AES encryption for over-the-air communications. This is the same encryption that is used in WPA2, which is the de facto standard for Wi-Fi communications and is accepted by IT professionals around the world,” Sharp notes.
“Couple that with a hardened join process for WirelessHART devices requiring every device to have a join key and the ability to change the active advertising features in gateways, and you can limit the accessibility of the network,” he points out. “As
with any network,” he continues, “when looking at network security, there are two things that must be considered. Is the data protected as it flows over the medium (like wireless), and are the devices that are on the network suppose to be there? This relates to encryption and authentication, and WirelessHART covers both of these aspects.”
NIVIS is also providing a gateway prod-uct, as well as becoming one of the four firmware stack suppliers for WirelessHART. The firmware stack is a chip and code set that takes a standard IEEE 802.15.4 radio and makes it WirelessHART. The fact that there are now four different vendors for the stack indicates how robust the standard is and how interoperability is built into the system from the firmware layer out. NIVIS provides a com-plete WirelessHART development
kit for companies who wish to use its firmware stack.
Siemens, too, has jumped on the HART 7 and WirelessHART bandwagon, with a preliminary offering of pressure and temperature transmitters, a WirelessHART adapter and a Wire-lessHART gateway. Siemens is also producing a maintenance and diagnostic station to extract and manage maintenance information from wired and WirelessHART field devices.
Endress+Hauser, the world’s largest supplier of field transmitters, has produced a WirelessHART adapter and a new version of its Fieldgate pro-tocol gateway to work with WirelessHART. This way, any existing E+H field transmitter can be quickly and easily retrofitted with WirelessHART, and, through the Fieldgate and OPC, commu-

nicate with a control system. According to Victor Wolowec, E+H vice president of solutions, “Adding adapters immediately allows any HART 5 device to enter a WirelessHART network and transmit its information to the gateway. This might be pro-cess values for monitoring ap-plications or health data which is not normally available over a 4 - 20 mA connection.”
But it isn’t just large companies like Emerson, Siemens, Endress+Hauser, Pepperl+Fuchs and ABB who’re bringing out innovative Wire-lessHART products.
MACTek’s Thomas Holmes
talks about the MACTek “Bul-let,” a most interesting imple-mentation of the specification for WirelessHART adapters. “The Bullet WirelessHART adapter is an intelligent com-munication device that provides cost-effective wireless connectivity to both existing and new control and monitoring applications,” he says. “This device is much more than a simple router or convert-er and should be considered as being more like field-hardened intelligent I/O.”
MACTek’s product is an example of the diversity of the HART Communication vendor community.
While there are other Wire-lessHART adapt-ers, MACTek has taken the adapter concept consider-ably further than most—and it con-tinues to be entire-ly interoperable
with other devices. Holmes de-scribes the product. “MACTek will offer eight Bullet models differentiated by hazardous-ar-ea certification (GP, IS, XP and XP-IS) and by the number of HART field devices supported in HART multidrop mode (two and eight supported devices),” he says. “Every Bullet model supports one device in standard (non-multidrop) HART com-munication mode or will trans-mit the measurement PV from a non-HART analog device.”
ProComSol does HART 7. Its HART modems and PC-based software work fine with HART 7, because it is backward-compatible with all the HART versions before it. “One of the most important new capabilities of HART 7,” says Mike Fersky, marketing manager of ProCom-Sol Ltd., “is exception report-ing.” In exception reporting, the device only reports data if it is significantly different from what went before.
From the largest automation companies to some of the small-est, the depth and breadth of the HART technology ecosystem, wired and wireless, and the HART standards-based solu-tion make the choice of HART communication for any plant an easy one.

For more than 20 years, HART Communica-tion has been the fieldbus protocol that has been used the most. There are over 30 mil-
lion installed HART-enabled devices, worldwide. That’s more than double the number of devices installed by the next most common fieldbus. Why is this true? HART Communication has always been built on open standards. The IEC recognizes HART as part of its Industrial Communication Networks and Device Description Language (EDDL) standards. WirelessHART is built upon the IEEE 802.15.4 standard for low-power mesh radio networks. And WirelessHART itself is now an IEC standard, IEC62591. Another reason is that HART maintains the conventional 4-20mA signal, another international standard.
Typically, most users are familiar with the use of handheld communicators, such as the Rose-mount 375 or 475 handheld communicators, or of PC-based communications software, such as ProComSol’s Devcon2000 Smart Device Commu-nicator. These devices are for manual program-ming or diagnostic checking of a plant’s HART-enabled field devices.
And since WirelessHART is HART, anything you can do with a handheld or PC-based com-municator, you can do wirelessly through Wire-lessHART.
There is so much more that you can do with your already existing HART-enabled devices, so let’s look at what some end users have done.
How wired HArT works“HART” is an acronym for Highway Addressable Remote Transducer. The HART Protocol superim-poses digital communication signals at a low level on top of the 4-20mA. This enables two-way field communication and makes it possible for addi-
tional information beyond just the normal process variable to be communicated to/from a smart field instrument, and there is no interference with the 4-20mA signal.
HART technology is a master/slave protocol, which means that a smart field device (slave) only speaks when spoken to by a master. The HART Pro-tocol can be used in various modes such as point-to-point or multidrop for communicating information to/from smart field instruments to control systems. HART Communication occurs typically between a smart field device and a control or monitoring system. Best of all, HART Communication occurs using standard instrumentation-grade wire and using standard wiring and termination practices.
The HART protocol provides two simultane-ous communication channels: the 4-20mA analog signal and a digital signal. The 4-20mA signal communicates the primary measured value (in the case of a field instrument) using the 4-20mA cur-rent loop—the fastest and most reliable industry standard. Additional device information is com-municated using a digital signal that is superim-posed on the analog signal.
The digital signal contains information from the device, including device status, diagnostics, addi-tional measured or calculated values, etc. Together, the two communication channels provide a low-cost and very robust complete field communica-tion solution that is easy to use and configure.

access real-time continuous pro-cess variables and diagnostics. By accessing this real-time intel-ligent data Mitsubishi Chemical is able to diagnose abnormal process conditions and track equipment health 24 hours a day. As a result, peak produc-tion performance has improved, with an estimated operational savings for the plant of $20,000 to $30,000 USD per day.
“Diagnostic parameters that help detect signs of an abnormal situation or degrading perfor-mance are dif� cult to obtain with simple handheld devices
because they require a manual, time-consuming, step-by-step approach,” says Takayuki Aoyama, team leader, instrumen-tation group, Mitsubishi Chemi-cal. “HART technology made it possible to access this data without manual operation. This made it much easier for us to gather data and detect abnormal situations from � eld devices and has reduced maintenance costs by 10 percent.”
Manage Your Inventory. Tank level and inventory management is an ideal application for a HART multidrop network. The
HART network digital update rate of two process variables per second is suf� cient for many tank-level applications. A multidrop network provides signi� cant installation savings by reducing the amount of wir-ing from the � eld to the control room, as well as the number of I/O channels required. In addition, many inexpensive process-monitoring applications are commercially available to further cut costs.
HART multiplexers are avail-able from multiple vendors, such as Pepperl+Fuchs and Phoenix Contact.
In fact, as Gerrit Lohmann, Pepperl+Fuchs’ wireless product manager, points out, “When a HART 5 device is already installed and wired in the � eld, it does not initially make much sense to upgrade this device with a WirelessHART Adapter just to access the diagnostic data. Normally, a HART Multiplexer is the superior solution in terms of investment and operational
HART multidrop enables cost-effective inventory control.

costs. It has been shown that the hardware costs alone are signi cantly higher when implement-ing a WirelessHART solution verses a standard HART Multiplexer installation. Furthermore, the performance of a wired HART Multiplexer could be considered more stable when consid-ering site constraints, distance limitations and network-related issues.”
Lohmann says, “With a HART Multiplexer, a short process shutdown will probably be required during the installation.”
He goes on to note that there are advantages to using WirelessHART. “A plant shutdown is normally not required since the devices can be upgraded individually; however, the instru-ment may be of� ine for a short time during the instrument commissioning process. The existing wiring in the marshalling area is not affected, so during and after installation of the Wire-lessHART Adapters, the plant should continue to operate. There is normally enough space to mount the WirelessHART adapter on or near the eld instrument, so installation is relatively easy. A HART Multiplexer requires control room cabinet space. This premium area is normally oc-cupied with other existing hardware. As a result, the costs of an additional cabinet or junction box must be considered.”
NEW FEATURES IN HART 7HART 7, the rst major upgrade of the HART Communication Protocol since 2001, includes signi cant new features and upgrades over HART 5 and HART 6. Bob Karschnia, Emerson Process Management’s vice president of wireless, describes them. “HART 7 is an evolutionary step in HART technology that continues the tradition of adapt-ing to changes in instrumentation design,” he says.
“HART 7 now allows eight variables to be com-municated in a single message re� ecting the trend for more multivariable devices that do calcula-tions, as well as making measurements or actuat-ing a valve,” continues Karschnia. “As the impor-tance of these additional variables has become evident, HART 7 now provides status indications for each one. To further support the multiple val-ues provided by these products, the user can now simulate each variable providing the ability to do a “loop check” on both the analog and digitally communicated values. Data is now time-stamped. Although the wired devices may not have a real-
time clock, they can still provide a relative time and eventually the control systems will become capable of synchronizing time across the wired HART devices, which will allow a much more accurate picture of plant performance. In the same way, system enhancements for HART 7 will be able to take advantage of condition-based report-ing (report by exception), alert acknowledgement, data trending and other features that will appear in the HART devices.”
As Steve Todd, vice president of sales and marketing for Moore Industries-International, reports, “We anticipate HART being used more frequently in multidrop applications. Devices such as our TCM Multichannel Temperature Concen-trator System have multiple channels and can have multiple devices on a single line. Devices like this take full advantage of the new features found in HART 7. The squawk-and- nd device features will be very useful for con guring devices in multi-drop applications. The new sub-device feature will also be useful on our multichannel devices so that their internal data can be more logically organized. Exception-based reporting will improve the responsiveness of multidrop applications by reducing the data that must be transferred.”
And of course, HART 7 includes WirelessHART.
The WirelessHART StandardWirelessHART has already been used in a number of applications that would be dif cult, if not impossible to do with wired HART. BP has expanded its Cherry Point re nery applications, installed Emerson’s Wire-lessHART network throughout the tank farm in its

R&D facility in Naperville, Ill., U.S., and is making installations at its other re� neries around the world.
BP Cherry Point is a 225,000-bpd re� nery lo-cated in northwestern Washington State in the U.S., and is the largest supplier of calcined coke to the aluminum industry. One out of every six aluminum cans is made using BP Cherry Point’s calcined coke.
WirelessHART-enabled Smart Wireless transmit-ters on the re� nery’s calciner unit monitor bearing and calciner coke temperatures to help prevent fan and conveyor failure. Fans can cost up to $100,000 to repair, but more important, can be down for up to 10 days with associated production losses. The 15-transmitter wireless installation, originally done in 2006, continues to run reliably while eliminating operator rounds in the � eld.
Endress+Hauser has engineered a robust Wire-lessHART network that reliably communicates with 44 WirelessHART adapters and two Fieldgate gate-ways to adapt magnetic � ow meters and pressure transmitters spread linearly over 2400-foot-wide leach � eld sections. These leach � elds are regularly relocated, and the � exible WirelessHART redundant and mesh architecture accommodates the relocation with a minimum of effort.
Siemens, ABB and other vendors have also installed WirelessHART projects. It is estimated that there are already over 1400 installed Wire-lessHART-enabled � eld devices in the world.
MACTek has done one of the most innovative projects with WirelessHART to date, at Progress Energy in Crystal River, Fla. Dick Fletcher, of Progress Energy, says, “Our Performance Testing group needed a new data acquisition system. The data acquisition system needs to collect data from a variety of pressure and temperature transmitters. In addition, the system needs to be portable and � ex-ible enough to operate with a constantly changing number of instruments and scan rates. The system needed to be portable, able to handle a variety of instruments (typically high-accuracy pressure and temperature transmitters), be easily con� gured, as every test is a different con� guration, and inter-face with standard commercial instruments using standard protocols. In the long term, we wanted to broaden the scope of the data acquisition system from being simply for thermal performance testing to also include other testing, such as dye dilution � ow testing and equipment diagnostics, and make the real-time test data available upon the corporate wide-area network.”
Fletcher and his team decided on a multidrop con-� guration with existing wired HART transmitters, but connected to MACTek “Bullet” WirelessHART adapters, since each Bullet can handle up to eight HART transmitter inputs in multidrop mode.
“Far fewer cables have to be deployed now, and situations that placed cables at risk of dam-age (i.e., crossing roads) can now be handled by radio links instead,” Fletcher reports. “Now, we are collecting the data in real time directly into an Excel spreadsheet via Matrikon Analytic’s Excel Reporter plug-in for OPC data.”
This application is a classic example of how WirelessHART and wired HART work together.

Both are HART, and HART is robust enough to operate in the challenging environment of a power plant and have the devices and gateways continue to communicate reliably.
HOW DO I?Wired HART installations are very straightfor-ward, whether they are 4-20mA home-runs or multidrop installations. WirelessHART is some-what less so for two basic reasons. First, WirelessHART is new, and not everybody understands how to install and commission working (or wireless) systems, and second, the fact that it is a radio-based system means that WirelessHART is a little trickier to install than a standard two-wire cable.
In a brown� eld ap-plication, of course, you can apply trial and error like the Verizon man (“Can you hear me now?”) and end up with a correctly sited WirelessHART device communicating to a gateway. In a green-� eld application, things may be a little different.
Pepperl +Fuch’s Gerrit Lohmann says, “There are some rules one has to consider when installing a WirelessHART Network,” he says. “Generally, when the devices can ‘see’ each other in a line of sight, they will communicate. This would be the key when designing a network with no existing tanks or structures. Depending on the packing density of an area—which determines the maxi-mum communication range—one can estimate if the devices can talk to each other over the dis-tance. Finally, a check on the number of instru-ment ‘neighbors’ is necessary. There should be two network neighbors at a minimum in a mesh net-work, while three is better. If a device has only one neighbor, or the distance between them exceeds the site constraints, a router may be required.”
Endress + Hauser’s vice president of solutions, Victor Wolowec, is not so sanguine. “A site survey of an existing facility should always be made before any WirelessHART device is installed. This
is a standard part of Endress + Hauser’s solution offering. The site survey determines the best posi-tion for the gateway relative to the devices and determines whether any repeaters are necessary. The adapter concept has a certain advantage here, since it allows the dipole antenna to be placed at some distance from the measuring point.”
Vendors have started to include wireless net-work managers in their product portfolios for
WirelessHART. Since late in 2008, Emer-son Process Man-agement has been including an AMS “Snap-On” that helps users design Wire-lessHART networks.
Bob Karschnia says, “AMS Wireless Snap-On is a tool that can be used with plot plans
or simple scaled drawings to layout the network. AMS Wireless Snap-On can be used as a stand-alone application for site planning and in a real-time mode to monitor the network. This tool incor-porates the best practices recommended for planning a network to minimize the chance that a device won’t be able to join the network.”
The self-organizing mesh capability of Wire-lessHART (IEC 62591) does not require a line of sight for a robust network. If devices do not join the network, there are several options, includ-ing changing the gateway placement, changing the height of the device to get above obstacles, using an antenna with a longer range or adding strategically placed repeaters. Karschnia says the AMS tool can help identify “stranded” devices and visualize how to remedy the issue.
”By either following these best practices or using the tool, EPCs can be assured that the wireless will work with no issue. More important, documents and procedures that are needed by EPCs are now available to help them execute projects with wire-less content. The bottom line is that wireless has been made easy,” Karschnia concludes.
With the new features of HART 7 and the wireless capabilities of WirelessHART, it is easy to see why HART remains the world’s leading � eld communica-tion protocol for the process industries.

Using HART for Asset ManagementWirelessHART extends HART 7 capabilities for
automation asset management
W irelessHART has two big money plays. First, the one that will likely pay off the fastest, is the ability to add, simply and
inexpensively, many more sensors than plants use currently in order to keep up with new regulations and tighter control requirements. And once the wire-less mesh network is installed and paid for, adding additional measurement to the network becomes extremely cost-effective. This in itself is an excellent way to make sure that there is enough real-time data to ensure the success of advanced process control systems and complement the soft sensors some plant optimization systems can employ.
The second big money play for WirelessHART is asset management.
Asset management starts with the measurement assets in the � eld. Thirty million HART-enabled devices are already installed, and the vast majority of them are connected to control systems that aren’t equipped to receive the HART Communication digi-tal signal. In addition, there are thousands of pieces of rotating machinery (pumps, motors, fans, etc.) from which it has been problematic to get even rudi-mentary data like temperature, pressure and vibra-tion—because they are turning. So WirelessHART will permit more than just “instrument” maintenance in the asset management system. It will permit many other, non-traditional measurements to be input directly into the asset management system.
Current asset management solutions require that operators and technicians equipped with mobile data devices do rounds—an exceptionally expen-sive use of human resources. Equipping position sensors, low- and high-alarm switches, vibration, pressure and temperature sensors on rotating ma-chinery with WirelessHART communication will allow operators to spend their time doing more high-value work than being a “clipboard jockey.”
MAKING IT ALL WORKIt is all about interoperability. The insistence of the HART Communication Foundation on interoper-ability, which Ed Ladd, director of technology pro-grams for the Foundation, de� nes as, “Freedom to use any manufacturer of HART devices, and mix manufacturers and products in the same network,” has been critical to the HART protocol becoming ubiquitous—with more than twice the number of installed HART-enabled � eld devices than the next nearest competing � eldbus.
Ladd continues, “Controllers use the same universal commands to communicate with all devices, and there are standardized diagnostics in every device. The same tools work with wired and wireless devices independent of the manu-facturer with a goal of one EDD per device to work on all EDD-enabled hosts. Users have the freedom to use any revision—of the Protocol, of
USING HART AND WIRELESS
Interoperability makes asset management possible.

the device—without mandatory upgrades to tools or applications.”
Because WirelessHART is HART, applications like the MACTek Bullet application at Progress Energy described in the previous article, where multidrop wired HART and WirelessHART are combined to provide the solution to the test department’s issues with obsolete devices, just work. There’s no finagling and no special or custom interfaces because it is all HART and that means interoperability.
Gerrit Lohmann, Pepperl+Fuchs’ wireless prod-uct manager, says it well. “As the pressure contin-ues to grow to optimize in a cost-effective man-ner, the stranded HART data contained in legacy instruments will be extracted via the customer’s existing hardware, through a HART multiplexer or by the latest WirelessHART solution.”
Ira Sharp, product marketing lead for wireless for Phoenix Contact, agrees. “This extra information can be used for predicative maintenance and more effective scheduling of maintenance, and provide a more accurate record of the devices being used in the field and their age for asset management.”
Emerson’s vice president of wireless, Bob Karschnia, points out, “What’s key is understand-ing who will use the stranded data and what they will do with it. A THUM adapter enables the right information to easily get to the right people at the right time. This information might not have been important to the control scheme, but it is likely to have high value to others. Wireless unlocks this
information in a cost-effective manner without complicating the control system.”
“Remote wireless access to the HART devices allows engineers and technicians to remotely con-figure devices from a central location,” says ABB’s product manager for asset management and wire-less, Eric Olson. “Beyond making the configuration task more convenient, it also saves time and reduces potential wiring mishaps by not having to use a field handheld to make the configuration changes.”
This is a clear improvement for maintenance and asset management, he says, because, “It also allows for better documentation as the device configura-tion can be saved, printed, and if a device needs replacement, the configuration can be restored quickly. Many devices support a simulate function that can be initiated remotely via wireless to verify the device installation and system connection from a single location. This saves time as technicians no longer need to roam the plant to perform these tasks. And, of course, all of the wireless devices can be monitored remotely to verify their operation.”
Because of the demand for increasing plant and unit optimization, most large vendors of control systems have released asset management software that integrates with the control system software they sell. The integrated and interoperable diag-nostics in every HART-enabled field device are critical to economical asset management. It simply isn’t economically possible to send operators and technicians out with handheld devices to down-load diagnostics from devices—and make sure that the data is correct. With HART it is easy, and with WirelessHART it is easy to do for any installed HART-enabled field device, from pressure transmitters to valve actuators to process analyz-ers. The elimination of operators making rounds to record process measurements manually not only improves process operations, but also saves time and increases operator safety!
Eric Olson says, “So what are the benefits of plant asset management? Wil Chin, ARC research director, has reported typical results from oil and gas and the chemical industries. He says that in all areas, there are real tangible savings to using asset management, and it is clear that WirelessHART adapters can expand on this by increasing the

number of devices available in an existing facility for monitoring purposes.”
With this kind of savings potential, process industry companies are going to be focusing on the advantages that HART and WirelessHART are able to give them. Some vendors and knowl-edgeable end users estimate that as many as 30% of the existing installed wired HART devices will have WirelessHART adapters fairly quickly, while
others will wait for shutdowns and turnarounds to install HART multiplexers. That 30% works out to approximately 10 million devices. Wire-lessHART has a huge potential for improving operational ef� ciency in process plants worldwide.
END USERS WINBecause every process plant in the world has HART-enabled � eld devices, it makes sense to concentrate on leveraging the assets the plant al-ready has. The interchangeability and interoper-ability of HART-enabled devices, whether wired or wireless, means that a decision on “what technology to use” becomes “how best do we use the technology that we already have?”
Integrating information from HART field devices into control, monitoring and asset management applications using wired HART, WirelessHART or a combination, is the most effective way to optimize and manage your measurement assets.
