regarding emergency response and
mustering if there is an event in the
plant. By having security devices and
alarms wirelessly connected, you can
be notified immediately if an event
causes an alarm, see via the cameras
if the area is occupied, use handheld
mobile devices to track the locations of
employees to determine who is in the
area and who is not, provide mustering
instructions via speakers or handhelds
and know who has reached the
destination and who is still missing.
" The wireless umbrella is helping to
solve huge safety issues at a low cost, "
she explains. " It requires a few applications
and a good wireless umbrella
to make it super seamless and easy to
meet security and safety mandates. "
A blended approach
While the ability to track process
components, safety, security and numerous
other applications via wireless
technology has obvious speed,
efficiency, operational, safety and cost
benefits, there still remains the issue
of how to tie it all together in a useful,
easy-to-access manner. " It's getting
to the point where it's less about the
wireless devices and technology itself
and more about what to do with the
information being brought in by these
devices, " says Rogowski. " The focus
now is on taking all that information
and providing a way to get it to a
dashboard viewed by workers and operators
so they can make better, more
informed decisions. "
Jeremy Bryant, manager of communications
and identification business
with Siemens (Alpharetta, Ga.), says
this should be done using a combined
technology method. " As standards get
developed, we will start to see users
blend a variety of different technologies, "
he says. For example, wireless
instrumentation will be used to obtain
data from the equipment, another
component will process that information
and then a different technology,
such as Wi-Fi, may be used to move it
along the backbone (an industry term
for getting data from the middle component
to the control system) and perhaps
an entirely different technology
will be used to sort the information in
this central location and send it to the
appropriate destination.
Typically, says Justin Shade, wireless
product marketing specialist, with
Phoenix Contact (Middletown, Pa.),
wireless devices such as measurement
