integrates easily. "
For this reason, Phoenix Contact
developed mACX signal conditioners
(Figure 3) with functional safety
for processors who want to do analog
signal conditioning but need to
maintain an SIl rating. The signal
conditioners have been developed
and produced according to the standards
for functional safety. In addition,
they are available with maximum
explosion protection and, with
mACX Safety, users can integrate
analog signals easily into the safety
application, for intrinsically safe circuits
in hazardous areas.
Another example of simplified
integration of devices includes
Endress+Hauser's (E+H; greenwood,
Ind.; www.us.endress.com)
Promass Coriolis density/massflow
family of flowmeters, as well as other
E+H flow and analytical instruments,
which implement the oDVA EtherNet/IP
Standard (Figure 4).
" Intelligent devices continue to
flourish by moving from supplying
self-diagnostic information to providing
operators/technicians with actionable
problem-solving guidance, "
says Craig mcIntyre, industry manager,
chemical, with E+H.
The benefits of employing a Webbased
device like the Promass Coriolis
flowmeter are many, according to
mcIntyre, including a direct, two-way,
high-speed digital communication of
density, flow, volume flow, temperature
and diagnostics/configuration
information into an EtherNet/IP architecture
environment in place of a traditional
one-way analog/frequency/
pulse I/o and associated controller
scaling/integration programming.
The server-based Promass has
Perfection is
Better Dispersion and Control
an embedded Electronic Data Sheet
and associated add-on profile, which
are installed on the controller side,
supporting rapid pre-configured integration
for control and visualization.
Pre-engineered faceplates for
Promass are provided for rapid HmI
visualization development. And addon
instruction exchanges data between
each process variable located
in the Promass and the faceplate installed
on the display. The name of
the specific add-on instruction becomes
the link from the Promass to
the faceplate on the graphic.
Further, says mcIntyre, addiPerfecting
Particle Size
The Sturtevant Micronizer®
jet mill reduces the
particle size of pesticides, herbicides, fungicides,
insecticides and dry chemicals to narrow particle
size distributions of 0.25 microns or larger without
heat buildup.
* Better control properties - dispersion & reactivity
* Particle-on-particle impact, no heat generation
* Simple design, easy to clean
* Abrasion resistant for long life

tional cost and risk reductions can
be gained during the integration,
field implementation and field service
phases through the associated
lifecycle-management system.
Integrated application-engineering
tools, factory-maintained device
documentation and maintenance
tools, and information-integrated
support of engineering software implementations
can bring increased
information value and access to associated
stakeholders.
" The use of server-based devices
integrated into secure local and WAN
implementations to reduce integration
costs and facilitate remote management
is increasing, " says mcIntyre.
And, this type of intelligent device,
with its ability to seamlessly deliver data
and information to a control system
that ties process information to enterprise
information in realtime, may mark
the arrival of the Internet of Things in the
process control industry.
