Increasing transparency and
flexibility at the field level
Field instrumentation with WirelessHART communication for
innovative and cost-effective solutions
Answers for industry.
New possibilities
in the process industry
Wireless products have fundamentally changed our lives – and they
are also playing an increasingly important role in the industrial
environment. Here too, the enormous potential of wireless technology
opens up totally new perspectives. In addition to industrial wireless
LAN (IWLAN) for local wireless networking, GPRS- and UMTS-based
telecontrol systems are already widely used in the world of automation
because they are ideal for monitoring and controlling remote plants
and facilities. WirelessHART is the first industrial and open standard
(IEC 62591) for wireless field communication that fully meets the
requirements of the process industry.
Success factor: wireless communication
WirelessHART: simple, reliable, secure
To achieve lasting success in the face of global competition, companies need to permanently improve their productivity while minimizing the total cost of ownership.
This calls for new measures and new concepts.
With over 35 million devices installed worldwide, HART
technology is the most widely used field communication
protocol for intelligent process instrumentation.
Wireless solutions offer many more benefits than just the
elimination of cabling and installation costs. Users also
profit from significantly faster commissioning and more
efficient maintenance as well as greater flexibility and
mobility. Wireless technology ensures improvements in
production quality and plant safety. All of these advantages add up to greater overall plant availability.

WirelessHART is an intelligent evolution of the proven
4 –20 mA HART technology released by the HART Communication Foundation (HCF) as part of Specification V7.
WirelessHART is backward compatible with wired HART
technology, and as such offers maximum protection for
investments in hardware and software, tools and expertise.
WirelessHART is an open industrial standard (IEC 62591)
developed to meet the special requirements of wireless
communication at field level in the process industry. It
consistently fulfills all specific requirements for reliability,
security, cost-efficiency, and ease of use.

WirelessHART product family
Industrial wireless LAN
■ Battery-powered WirelessHART transmitters are ideal
for remote measurements, for deployment in harsh
environments, for temporary ad hoc measurements, and
for the expansion and replacement of field devices.
SCALANCE W access points and client modules allow
optimal configuration of IWLAN networks according
to the international standard IEEE 802.11. They feature
a high degree of ruggedness, and security in all
applications, even in explosion hazard zone 2.
■ WirelessHART adapters provide wireless communication capability for existing wired HART devices.
■ The WirelessHART gateway manages the network as
well as the security of the network and of the data in the
network. It also serves as a proxy to higher levels in the
automation pyramid (for example, to SIMATIC PCS 7,
SIMATIC PLCs or to systems of third-party suppliers),
and is a link to access the devices in the network.

WirelessHART answers your challenge
WirelessHART opens up new communications options that
were either not practical or simply not possible in the past
due to the given operating environment or for economic
reasons.
■ Flexible for installation, replacement, or upgrading;
ideal for temporary measurements and for measurements on rotating equipment.
■ Cost-efficient for remote facilities and locations difficult
to access due to environmental or technical conditions:
significant cost-savings for cabling, commissioning, and
engineering, as well as reduced operating costs thanks
to increased plant efficiency and lower maintenance
expenditures.
■ Maintenance-friendly thanks to access to valuable
diagnostic information for enabling predictive maintenance strategies. Maintenance expenses for cables and
connections as well as manual checking of equipment
status are a thing of the past.
■ High plant availability and production quality through
optimized wireless installation, reduced black measurement points, higher transparency throughout the plant.
With our WirelessHART solutions, users profit not only
from lower total cost of ownership but also from significantly improved security, reliability, and productivity.

Applications
The use of WirelessHART products in process
industry applications can be classified as follows:
Application type 1:
Wireless makes stranded information airborne
Application type 2:
Wireless instead of wired communication
In many plants, HART devices are analog-wired in a distributed control system (DCS). This means that a great
deal of valuable diagnostic information is not accessible
in the field, and devices must be maintained manually at
regular intervals. This leads in turn to high maintenance
costs and the risk of unscheduled downtimes. Installation
of a WirelessHART adapter on existing 4 – 20 mA HART
instruments means that equipment information is accessible from maintenance stations without changing the
system that is running. Access to valuable diagnostic and
device information offers a wide range of advantages,
including higher process performance and reliability and
improved maintenance approaches.
WirelessHART solutions are considerably more cost-efficient
and flexible than conventional concepts for improving
production quality, plant safety, and process transparency
through the addition of new measuring points.
WirelessHART significantly reduces costly and timeconsuming cable installations and allows much faster
commissioning of field instrumentation and loop tests.

WirelessHART works perfectly with either moving or rotating
measurement points. Using WirelessHART for monitoring
levels in tanks, including tank farms, results in short commissioning times and significantly reduced costs. Digital communication means that process variables are available in control
systems with no loss of accuracy. Up to eight process variables
can be sent at once. The balanced and intelligent use of both
wired and wireless communication in automation solutions
results in the highest possible performance across the entire
life cycle of your plant.
