Reliability industry standards.
New Measurements – Cost Savings in Reduced Engineering
By using WirelessHART technology, a new measurement point can be added inhours or days rather than weeks or months. Users save with reduced engineeringtime, faster commissioning, and more efficient maintenance.
Installation costs can be reduced further by using the HART all-digital multidrop
mode where multiple devices connect to a single WirelessHART adapter.

“WirelessHART builds on the solid
foundation of HART Communication
enabling users to quickly andeasily gain the benefits of wirelessautomation while continuing
compatibility with existing devices,tools, skills and systems.”
WALLY PRATT
Director - Field Communication Protocols

Remote and Difficult to Access Process Areas
Whether it’s rotating equipment across a public road or through a plant with little
spare room on cable trays, all plants have difficult-to-access areas. By utilizing
wireless technologies these areas now become accessible for new measurements
without the need for additional expensive cabling.

Asset Management – Improve Plant Reliability
Critical measurement devices in aplant can be more efficiently integrated
into your maintenance strategy byusing WirelessHART technology. It
enables process and device diagnostic
information to be used to shift to a
predictive maintenance strategy. This
increases the reliability and safety of yourplant, while reducing repair costs andunplanned shutdowns.

WirelessHART technology is field provenworldwide with billions of operating hours.
It is low-risk, low-cost, interoperable anduses the same tools and skills as the HARTProtocol.

Host data integration provides real-timeaccess to device diagnostics to help lower
your operation costs and improve plantreliability. HART-IP technology significantly
simplifies the connection configuration andthe information integration.
WirelessHART devices communicate with a gateway to deliver process
measurements and device diagnostics. The gateway connects to the host via wired
or wireless options including:

6The Global
Process The HART Protocol is the industry standardwith tens of millions of HART devices installed
Communication worldwide. The use of real-time information in
HART devices facilitates a fundamental shift
Standard in plant operations.
The HART Protocol:• is supported by all leading suppliers• is easy to install and use• is low cost and low risk
• benefits all phases of the plant life cycle“WirelessHART devices offer anumber of advantages beyond thelow installed cost that often drives theend user choice of wireless. Wirelessinterfaces always provide access to arich range of instrument performanceand diagnostic information. The rangeof applications that can be served
continues to expand, and device

The WirelessHART Advantage
With the increase in information and measurement points needed today,
WirelessHART technology can easily add these additional measurements without
new cable trays or new wires at a greatly reduced total cost.
WirelessHART is an evolutionary communication technology built on the solid
foundation of the HART Communication Protocol. It is the process industry’s firstinternational open wireless communication standard (IEC 62591; EN 62591).
When asked to name potential barriers to adopting a wireless solution, processindustry users stated their main requirements are: security, reliability and ease-ofuse. WirelessHART technology is designed to meet those requirements.

WirelessHART technology is a complementaryenhancement to the HART Protocol, providing
an additional capability that benefits both
existing and new monitoring and control
applications.
