DEBUNKING THE MYTHS
We take a closer look at
some myths surrounding PROFIBUS and PROFINET ... and
expose the perpetrators!
MYTH
1: PROFINET is PROFIBUS on Ethernet! (White Paper at
www.odva .org)
RESPONSE: PROFINET is NOT PROFIBUS on
Ethernet - it's MUCH more. It eases peer-to-peer integration;
it facilitates vertical integration; it simplifies
implementing motion control; it handles more devices and more
user data; it leverages IT standards and diagnostics.
MYTH 2: PROFINET is
non-standard Ethernet
RESPONSE: This myth originates with a
large North American Industrial Ethernet vendor and gets
perpetuated by clever people who really ought to check their
facts! PROFINET uses standard IEEE802.3 Ethernet, with TCP/IP
for IT connectivity and complete compatibility with TCP/IP for
realtime tasks. Standard duplex switches can be used
throughout a PROFINET realtime network. PROFINET is also a
unicast protocol, which means communications are
point-to-point and precise, unlike other Industrial Ethernet
protocols we could mention that multicast and so need an IGMP
Snooping option to avoid flooding the network! Like other
Industrial Ethernet protocols, PROFINET enhances standard
Ethernet with Application Layer extensions to suit the
automation domain. (The Application Layer is the same layer
that email and web browsers operate in.) PROFINET provides the
isochrononous realtime (IRT) needed for Motion Control. This
also uses standard Ethernet. Part of the bandwidth is reserved
for IRT with the balance allowing standard TCP/IP traffic.
This technique puts PROFINET way ahead of all the others in
Motion Control ... and without compromising Ethernet or TCP/IP
compatibility! Printers, displays, video systems, and other
TCP/IP devices work normally on a
PROFINET IRT network. It's a 21st
century way of doing things that is, frankly, world-beating!
Perhaps the myths are needed because the other protocols are
afraid of the power, simplicity and elegance of PROFINET? Then
again, maybe they're just jealous!

FREE 2006 PROFIBUS
TRAINING COURSES KICK OFF: The 2006 series of FREE PROFIBUS
seminars and workshops was kicked off recently. Classes have been
successfully concluded in Detroit, Houston, Cincinnati, Philadelphia,
Toronto, and Montreal. Hundreds of attendees now see the financial
benefits of using a fieldbus and the technical benefits of using
PROFIBUS and PROFINET. In Detroit, they were amazed at the number
of exhibitors who sponsored the event (14). In Houston, they realized
that the exhibitors were competitors who banded together to ensure
that users learned more about fieldbuses in general and PROFIBUS
in particular. In Cincinnati, they learned of the individual exhibitors'
PROFINET products by visiting their exhibits during breaks, lunch,
and the hosted reception. Almost everyone who completed a Course
Evaluation said the length was "Perfect." Their comments included:
"This was the best one-day class I've attended… ever." "I had time
to ask all my questions and the instructors were very knowledgeable
with their answers." Class space is still available. Exhibit space
is still available. Visit this
page for the latest class additions and for links to registration.

NEW CERTIFICATION
TRAINING COURSES: PTO and the PROFI Interface Center
(PIC) have added a PROFIBUS Installer’s Class and a PROFINET Certified
Network Engineering Class to their training program. This year marks
the sixth anniversary of the PROFItech certification program and
more than 300 attendees have been designated Certified PROFIBUS
Network Engineers in that time.
“PROFItech certification training teaches
users the appropriate installation, operation and maintenance of
PROFIBUS and PROFINET products and networks,” said Carl Henning,
deputy director of the PTO. “The industry is moving toward more
advanced communication for plantwide operations and PROFItech
classes teach users exactly what they need to know about
implementing network communication in their facilities.”
At the one-day PROFIBUS Installer’s Class,
participants receive hands-on training of PROFIBUS DP networks and
learn how to avoid common networking problems. Course material
includes PROFIBUS DP basics, system design and maintenance, fiber
optic installation and more. Participants receive 6 Personal
Development Hours (PDH credit hours) of advanced training from
qualified instructors. The PROFINET Certified Network Engineering
Class delivers hands-on training of the installation, operation and
maintenance of PROFINET products and networks. This class provides a
mix of protocol theory and hands-on problem-solving exercises.
Topics covered are Ethernet basics, PROFINET IO and PROFINET CBA,
network monitoring and diagnostics, security and more. Participants
receive 24 PDH credit hours and upon graduation receive an official
PROFINET Certified Engineer Certificate. Also included in the
program is a complete set of course materials, breakfast, lunch, a
PIC-hosted dinner, and a certification listing on the PROFIBUS
International (PI) website.
Other PROFItech courses offered include a
PROFINET IO Development Class and a PROFIBUS Certified Network
Engineering Class. Prerequisites for all classes include a
background in industrial automation and familiarity with basic
communication terms and features.
Mr. Henning concluded: “PROFItech now offers
more comprehensive training to all areas of PROFIBUS and PROFINET
systems. Certification ensures that users are knowledgeable and
well-equipped to manage their facilities.” To find a complete
schedule or to register for the PROFItech Certification Training
Program visit the PTO website at http://www.us.profibus.com/

PROFIBUS FIGURES
EXPECTED TO PASS 15 MILLION: Based on the numbers
of chips sold, the expected increase in installed PROFIBUS nodes in
2005 indicates that the total may now be well past 15,000,000,
increasing the lead PROFIBUS has as the world's most widely used
fieldbus. In the same period, the total number of PROFIBUS nodes in
the process industries probably reached close to 3,000,000!
NEC SECOND SOURCES ERTEC CHIP: Semiconductor giant NEC has announced that
it will start selling the ERTEC switch chips used for PROFINET IRT
applications. ERTEC chips are designed to support the critical
isochronous realtime capability for advanced Motion Control. ERTEC
400, a four port version for controllers, is available now. ERTEC
200, a two port version for field devices, is expected in Q2 2006.
The ERTEC chips include a powerful ARM9 processor and support data
transmission rates up to 100 megabits per second. As well as IRT,
they enable the wiring-intensive star topologies typical of Ethernet
to be replaced by bus structures similar to fieldbuses - a real boon
for Industrial Ethernet users. Real-time communication allows
control of up to 150 axes at a cycle time of 1 millisecond, with 6
megabytes per second of simultaneously transferable standard TCP/IP
data. Development kits will also be available from NEC.
LIFT OFF FOR GLOBAL
WEB SITE: 2006 began with two revamped global
web sites being unveiled - at http://www.profibus.com/ and http://www.profinet.com/. The
sites combine to feature color-coded access to PROFIBUS (blue),
PROFINET (green) and PI (silver) information, making navigation
much easier. PI is the new name for the old PROFIBUS International,
the umbrella organization representing PROFIBUS and PROFINET worldwide
in 24 countries.
LIFT OFF FOR NEW NORTH
AMERICAN WEB SITE: A new web site has just gone
live at http://www.us.profibus.com/,
focused on North American PROFIBUS and PROFINET activities. You
can find out what courses are taking place and in which cities,
and register online too. Register there also to receive regular
copies of this PTO email newsletter. Read

88% SAY TIGHTLY INTEGRATED AUTOMATION NETWORKS
ARE THE PRIORITY IN PROCESS: Market analyst ARC's 2005
fieldbus user survey shows conclusively that 'control in the field'
is NOT the most important fieldbus attribute! In fact, it's the
least important attribute! The survey took data from over 200 process
fieldbus users from across the globe - with more or less equal contributions
from Europe and North America, and a well-balanced sample from across
the process industries. What the survey reveals is that confidence
in fieldbuses has grown substantially in the 2 years since the last
survey was done, and that fieldbuses as a whole are now used widely,
even in mission critical applications. This is an important step
forward for all fieldbuses, said PI chairman Edgar Kuester, pictured
below. In terms of return on investment, more and more users find
that using fieldbuses is profitable. Such experiences have increased
considerably in the past two years. Approx. 27% of users see a return on investment within
the first six months and 18% within the next six months. 61% said
they are directly planning new fieldbus systems. The survey also
reveals that 88% of respondents think that closely-coupled process
and discrete automation networks are 'extremely important', 'important'
or 'very important'. PROFIBUS was designed specifically for this
hybrid need, says Kuester, "and our DP and PA solutions fit the
need perfectly." Added Kuester: "What's also interesting is the
trend in the number of people who think 'control in the field' is
not so important. In 2003 it was 9%, today it's 23%. This suggests
that it's increasingly seen as a nice-to-have feature whose cost
and complexity outweigh its practicality."
EVERYTHING ON ONE BUS IN PROCESS PLANTS: PROFIBUS
is the only field bus that can be used in all areas of hybrid process
plants where discrete applications and process control are combined.
All sectors of the manufacturing and process industries and all
applications from inbound to outbound quality check were taken into
account from the beginning, allowing PROFIBUS to be used universally.
PROFIBUS enjoys this unique position thanks to its modular design,
combining uniform communication technology with the relevant application
profiles and appropriately adapted physical transmission media to
form integrated solutions. This universality, combined with modern
technologies and the support of hundreds of device manufacturers,
has made PROFIBUS the clear market leader in industrial communication!
A comprehensive explanation of this unique
fieldbus is contained in an article published
here.

PROFINET TO SERIAL GATEWAY:
HMS Industrial Networks has announced the Anybus Communicator
for PROFINET. The Communicator is an intelligent protocol converter
that is used to connect automation devices to PROFINET via a
serial interface. Typical applications are PROFINET connections
for barcode or RFID scanners, weigh scales, frequency inverters
and motor starters, etc. It's DIN rail mounted and supports
RS-232, RS-485 and RS-422 signal levels at baud rates up to
57 kbit/s. For RS-232, one Anybus Communicator is needed to
connect one field device to PROFINET. Using the RS-485 interface,
up to 31 field devices can be connected via one Communicator
and, in this case, the cost of the PROFINET connection can drop
to less than $20 per device. Modbus is supported and it can
also be easily adapted to manufacturer-specific protocols using
Windows-based configuration software. HMS Industrial Networks:
