business performance. " Asset management
and condition-based monitoring
are excellent applications to get your
feet wet, but the bigger opportunities
lie in using wireless technology as a
solution to solve business issues like
how to achieve higher efficiencies in
the plant, " explains Ray Rogowski,
director of global marketing for wireless
business with Honeywell (Morris
Township, N.J.).
One of the largest roadblocks to fully
embracing wireless in this way is that
most facilities are already wired and
no one is going to spend money in this
poor economy to rip out fully functioning
wired devices and replace them
with wireless just to keep up with the
Joneses. So, vendors have begun to
develop adapters and gateways that
allow processors to reap the rewards
of wireless without large investments.
For example, Emerson offers the

Smart Wireless THUM Adapter, which
can be installed on existing HART
field instrumentation to free up diagnostics
and process information that
had previously been inaccessible in
wired, legacy system installations.
Most HART instruments have rich
diagnostics and process data, yet this
information goes unused because older
systems are not equipped to receive
HART communications. While it's
often too expensive and complicated to
access these data through traditional
wired methods, upgrading devices
with the THUM Adapter is a cost efficient
way to " see " the diagnostic and
process information. The THUM is a
WirelessHART device that can retrofit
almost any two- or four-wire HART
device to enable wireless transmission
of measurement and diagnostic
information. Devices with the THUM
Adapter operate as components of Emerson's
Smart Wireless self-organizing
field networks, delivering field intelliCircle

Figure 2. The CorrTran MV supports
WirelessHART to wirelessly provide realtime
monitoring of general and localized
corrosion and conductivity for early detection
and preventive maintenance
gence to enable improvements in quality,
safety, availability, operations and
maintenance costs.
Similarly, Pepperl+Fuchs (Twinsburg,
Ohio) offers a WirelessHART
Adapter that connects to any existing
HART device that supports HART 5
or 6 specifications, enabling it to become
a WirelessHART device. These
adapters mount directly into the cable
gland of the existing field device and
are available in various models to suit
specific application needs.
At the other end of the communication
path is Pepperl+Fuchs' WirelessHART
Gateway, which acts as an
interface between the wired structure
and the wireless network. The Gateway
contains the network management
and uses it to organize and control the
wireless network and connect this to a
control or SCADA system, via a fieldbus.
The signals of the field devices are
received and passed on via the appropriate
bus protocol in the fieldbus.
Siemens also offers the Sitrans
AW200 WirelessHART adapter,
which allows standard-wired HART,
4-20-mA devices to be connected to a
WirelessHART network. By installing
the adapter on an existing analogwired
HART device, processors can use
all diagnostic information at the maintenance
station without any risk of impairing
operations. The company's IE/
WSN-PA Link is a WirelessHART gateway
for connecting a WirelessHART
network to a plant host application.
With the integrated network manager,
it's possible to configure WirelessHART
networks and optimize network performance
and security settings.
