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!

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.

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

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 www.profibus.com
and 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 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

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
