DEBUNKING THE MYTHS
Ever
heard of Parrot Marketing? This month, instead of debunking
one myth, we announce a booklet debunking many
myths ... all at once!
'Pretty
Polly, Sweet Sue and the White Knight' takes a whimsical
look at the Parrot Marketing lying behind the myths we've
been exposing in recent issues of this newsletter, and
then responds by identifying the weaknesses of the Standard
Unmodified Ethernet (aka SUE) approach. Finally, over
the horizon gallops the White Knight to tell us about
the overwhelming advantages of PROFINET. This
booklet is a 'must read' if you're interested in Industrial
Ethernet.
See previous
issues for more 'debunks'.

Want to know more about PROFIBUS? Want to know more about
PROFINET? Want to know why you should use a fieldbus of any
kind? A recent ARC Advisory Group survey revealed that one
of the major factors inhibiting adoption of a fieldbus was
"lack of knowledge." Remedy that by attending one of the free
classes offered by PTO and the PROFI Interface Center. There
are still a few of each class type remaining. There are no
sales pitches but you can visit with the exhibiting vendors
during breaks, lunch, and after the class at the hosted bar.
If you register early you'll be eligible for an onsite raffle
for a $25 gift card. We hope to see you at one of the remaining
classes in Calgary, Los Angeles, Denver or Seattle. For a
summary of 2006 training opportunities, visit our North
American events page. For up-to-the-minute reports on
classes as they happen, visit the PROFIblog.
We anticipate that 2007 will bring even more opportunities
to attend a class. Watch www.us.profibus.com

PROFINET
DEVELOPER WORKSHOP: A well-attended workshop at Chicago
O'Hare (right next to the new Rosemont Expo Center) on the
day after the IES saw over 20 prospective
developers listen to a variety of PTO presenters on the technical
merits of PROFINET and how it can be implemented in products.
ARC Advisory's Harry Forbes introduced the topic of Industrial
Ethernet. Carl Henning (right) led the event and later blogged:
"Our first PROFINET Developer Workshop is now history.
We had seven tool providers show device manufacturers how
easy it is to add PROFINET to their products. It was amazing
to see the range of choices available – from customized services
to drop-in products. The seven tool providers: Hilscher North
America, Inc. HMS Industrial Networks, Inc. Real Time Automation
Siemens Energy & Automation Softing North America Grid Connect,
Inc. Woodhead Industries." He added that the success
of the PROFINET Developer Workshop is a sure sign of the increasing
market penetration of PROFINET in North America.

IN THE PROFIBLOG:
The PTO's Carl Henning,
who spends much of his time traveling with the
PROFINET Road shows, continues to write his
daily blog. Many good topics are covered, including the
recent ISA Expo, the IES and of course his various PROFINET
training classes and workshops. Carl always has a pithy comment
to make and he's well worth reading. At the recent ISA Expo
he noted (about one of the speakers): "One good point
about Industrial Ethernet he made is one we all too often
ignore: multiple different applications can run over Industrial
Ethernet at the same time. Yes, you can run PROFINET and email
and web browsers etc. all at the same time on Ethernet. In
fact, you can run Modbus/TCP, Ethernet/IP, and PROFINET at
the same time." So much for the differences ... and
so much for competitors who Parrot that PROFINET isn't standard
Ethernet. Pretty Polly!

PICCs AND PITLs
MEET IN SWITZERLAND: The PIC in Johnson City is just
one part of a global set of PI Competence Centers (PICCs) and
PI Test Labs (PITLs) supporting the international network of
PROFIBUS and PROFINET communities. PICCs and PITLs from Switzerland,
China, Czech Republic, France, Germany, Ireland, Italy, Japan,
the Netherlands, Poland, South Africa, US, and United Kingdom
met recently (above) at Winterthur, Switzerland where Quality
Assurance was an important topic: quality of services agreements
guarantee that a PICC has the know-how and equipment to provide
competent advice and services, and that qualified training courses
are offered. Strict regulations for the PITLs form the basis
of PI's device certification system and ensure that the certification
tests fulfill the same standards worldwide. Many people believe
that the close collaboration of PI's global network (that is
the Regional Associations, Competence Centers, Test Labs, and
of course over 1,400 member companies worldwide) is the real
differentiator for our technology.

PIC CHANGES
NAME AS PROFINET RAMPS UP: Here in North America our
PICC recently changed its name to the 'PROFI Interface Center'
(PIC) to more accurately portray current activities, which
include both PROFIBUS and PROFINET technologies. The PIC is
still quite active with PROFIBUS support but PROFINET-centered
activities have increased rapidly. Increased support for PROFINET
IO developers can now be provided. Also available from the
PIC is a PROFINET IO Development Kit for PROFINET IO devices
using standard Ethernet ASICs. As well as helping PTO, the
PIC undertakes it own activities, The majority of time is
spent on promotional work, mostly focused training events
for Automation, Process, Installers and Certified Network
Engineers for PROFIBUS and PROFINET. There are also Customer
In-House PROFIBUS and PROFINET Events. PROFINET IO Developers
Classes and In-House Industrial Ethernet Classes are on the
increase. PROFIsafe Developers Classes and PROFIsafe Seminars
are popular. On-Site Installation and Troubleshooting Visits
are also handled. A total of 68 events took place in the last
year, which 1641 people attended. The PIC also develops its
own tools, for example PROFINETCommander.
The PIC team consists of Ron Mitchell, Mike Hales, Karsten
Schneider, Hunter Harrington, and John Swindall. "It's been
a very busy year and we anticipate an equally busy next year,"
says Ron. "If you have any PROFIBUS or PROFINET questions,
need to schedule customized training or simply would like
installation advice, please e-mail us at profibus.sea@siemens.com".

 ETHERNET
SYMPOSIUM BRINGS MANY IE SOLUTIONS TOGETHER:
The Third International Ethernet Symposium took place in downtown
Chicago in October. As well as keynote and introductory speeches
on various aspects of the technology, delegates listened to
presentations from all major Industrial Ethernet players.
A panel session on Day 1 enabled key questions to be put to
each solution representative by ARC Advisory's Dave Humphrey
and shed light on many aspects of Industrial Ethernet. Break-out
sessions on Day 2 allowed case studies to be presented in
two streams. PI Chairman Edgar Kuester (above left) discussed
PROFIBUS and PROFINET Standards and explained how PROFINET
fits into the process industries in particular. Organized
by Siemens, the event is a valuable addition to the annual
automation calendar and we understand that it will travel
to Asia next year. For much,
much more comment go to Automation
World or ARCWEB
or of course the

CERTIFICATION
- WHAT IT MEANS: Many people wonder how the PI community
guarantees interoperability and quality. Well, it's all down
to certification, which PI members take very seriously indeed!
PROFINET and PROFIBUS devices of different types and manufacturers
perform different tasks in the automation process. In order
to do this correctly they must exchange information over the
bus as specified in the corresponding standards. Basis for
the certification is the framework for testing and certification
of PROFIBUS / PROFINET products and the test specifications
as well as the relevant standards. The documents can be found
here at 'Downloads'.
Thus, users have the assurance of error-free functionality
during the interoperation of devices from different manufacturers.
Similarly, certification ensures standard compliant behavior
within a PROFIBUS or PROFINET network, as defined by IEC 61158.
Both PROFIBUS and PROFINET devices are checked in a certification
test, which is performed by experts in special PI Test Labs
(PITLs). Only certified devices guarantee worldwide conformity
in an automation facility with products from different manufacturers.
For PROFIBUS devices, certification is strongly recommended
by PI and demanded by many end-users. For PROFINET products,
certification is mandatory.
- THE PROCESS OF CERTIFICATION:
The certification process (see graphic) is designed to ensure
reliable, interoperable and safe operation for users and
is similar for PROFIBUS and PROFINET devices. Details on
the PROFIBUS certification can be found here.
The device manufacturer first contacts a PI Test Lab (PITL)
for a certification test. The defined test cases are practically
oriented and reflect the industrial requirements. Therefore,
only those test cases are checked which might arise daily
in a real installation. The certification test is structured
as follows: Test of the hardware automated state machine
test; simulation of diagnostics and alarms; interoperability
test; inspection of the GSD file. Once a device has passed
all tests, the manufacturer can request certification from
PI.

QUESTIONS ANSWERED:
There's a lively free Forum at http://forum.profibus.com
where questions about PROFINET and PROFIBUS will be answered
by experts. Recent topics included:
- Q: Can you summarize the differences
between Industrial Ethernet and PROFINET?
- PROFINET is based on Industrial
Ethernet. Only in those parts where Industrial Ethernet
is not able to provide satisfactory results was it necessary
to extend standards to meet the requirements of end
users (e.g. for real time behavior). PROFINET is standardized
under IEC61158. With PROFINET, it is extremely easy
to match an application to an automation task: PROFINET
IO is optimized for fast data exchange with decentralized
peripherals; PROFINET CBA (Component Based Automation)
shows its strength when an automation plant is seen
as just a collection of functions, enabling modules
of functionality (i.e. components) to be easily and
quickly connected together; components can also be re-used
as often as needed, cutting engineering time dramatically.
- Q: Software implementation of PROFIBUS
DP. Possible?
- As PROFIBUS is standardized
in IEC61158 it is no problem to implement PROFIBUS DP
in software running at up to 1.5Mbs. Using higher transmission
rates you will run into problems. But, because of the
low costs of existing PROFIBUS ASICs it is much more
time-saving to use an available ASIC. In combination
with an existing software interface PROFIBUS is from
the user's viewpoint just a dual-ported memory where
the user can read and write the required data.
- Q: Is PA Profile V3.0 GSD a specific
GSD File, or is it built into the manufacturer's GSD?
- A PA Profile 3.0 GSD is a basic
GSD for all devices which are possible to run in a profile
mode. There are different profiles available like Temperature,
Level or Flow. These GSD-Files are specified in the
'PROFIBUS Profile for Process Control Devices, Version
3.0'. You can find the profile GSD-Files on the PI Website
here.

AROUND
THE WORLD: CHINA: On Sept. 4, 2006, CPO (Chinese
PROFIBUS User Organization) held a successful press conference
in Beijing on technology updates for PROFIBUS & PROFINET,
as part of PI's Road Show in Asia. More than 60 media and
journalists attended, including 3 major national TV stations!
If you're interested in the Automation Standards used in China,
the system of initials used are explained in this
recent Blog. While Ethernet/IP (and ControlNet, too) are
in the beginning stages of adoption in China, both PROFIBUS
and PROFINET are already Chinese National standards. JAPAN
The Japanese PROFIBUS Organization (JPO) organized a press
conference in Tokyo on Sept 7th at which Mr. Küster of PI
explained how PROFINET will cover process applications in
the future. One major topic was the announcement that three
major Japanese companies have expressed their support for
PROFIBUS and PROFINET as JPO members. These are Toshiba, Hitachi
High-Tech Trading and Fuji Electric Systems. Toshiba explained
that PROFIBUS fits its targets because it covers both factory
and process automation. Hitachi explained the expected benefits
of using PROFIBUS and PROFINET in its system while Fuji Electric
reported on its marketing of PROFIBUS during the past 2 years
and promised future support for PROFINET in its systems. SOUTH
AFRICA The PROFIBUS User Group of SA (PUGSA) recently
held a technology update on wireless communications in Johannesburg.
Engineers and Technicians from around the country attended,
completely filling the main auditorium. UK A call for
papers has been issued for the Third International PROFIBUS
Conference, which will be held at Coombe Abbey on June 26/27
2007. 'How to' papers are sought, for PROFIBUS and PROFINET.
Contact: uk@profibus.com NETHERLANDS
In June over one hundred guests from the process industry
converged on the Carlton Oasis hotel in Spijkenisse to enjoy
a breakfast courtesy of PROFIBUS Netherlands, PI and eleven
associated companies. One speaker was Dr. Hasso Drahten, general
manager of NAMUR, a major international organization for process
industry users has made a number of recommendations relating
to fieldbuses. Lifecycle Costs were another key topic. The
breakfast ended with a lively discussion! Guests used red
and green cards to respond to controversial statements such
as 'Important investments are frustrated by managers with
a bean counter mentality'. GERMANY: SPS/IPC/DRIVES
will feature the very latest of PROFIBUS and PROFINET at what
is fast becoming one of the best events in the worldwide automation
calendar. Interbus and PNO will be exhibiting side by side
once again with a joint booth and hospitality suite. One of
the highlights will be a huge PROFINET presentation. More

PROFIBUS
TESTER: Softing's latest PROFIBUS Tester - PB-T3 -
is a powerful, yet easy-to-use tool used to determine the
signal quality to each connected PROFIBUS device. Potential
faults in PROFIBUS networks such as device failures, communication
errors, or even plant shutdowns, are frequently linked to
poor signal quality and poor cabling. PB-T3 automatically
analyzes the physical layer of PROFIBUS networks and visually
displays the signal quality for each connected PROFIBUS device
separately, thus helping users to quickly locate and correct
errors. Automatic baud rate detection and the discovery of
duplicate address assignments also contribute to the ease-of-use
aspect of this innovative product. An included PROFIBUS master
simulator enables the PB-T3 to verify the integrity of PROFIBUS
networks during commissioning without having the actual controller
(e.g. a PLC) on-line. In addition, PB-T3 provides the exact
location of the problem by measuring the distance from PB-T3
to the device in question. Softing also has a new S7/S5 OPC
Server and NETLink-PRO, offering robust high-speed connections
to the S7 PLC-family and to compatible products from other
manufacturers. More from Softing North America at 978-499-9650

PORT PHYSICAL LAYER TRANSCEIVER: National Semiconductor's
DUAL port 10/100Mb/s High Speed Industrial connectivity devices
features Electrostatic Discharge (ESD) protection and offers
guaranteed IEEE 802.3u compliance. Additionally, it has Flex-Port
switching, which allows the two ports to be internally connected
to provide fully integrated range extension, media conversion
(100Base-Fx Fiber), hardware based failover and port monitoring.
Enhanced System Diagnostics use a TDR scheme for detecting
faults and cable diagnostics provide for real time monitoring
of link quality to enable fault prediction. More information
at www.ethernet.national.com.
PRESSURE
AND TEMPERATURE: The Sitrans P DSIII digital pressure
transmitter is the first PROFIBUS PA device designed for SIL2
safety shutdown in accordance with IEC 61508/IEC 61511-1.
A PROFIsafe driver has been added to the standard pressure
transmitter enabling the fail-safe transfer of the measured
values via PROFIBUS. The measure values include pressure,
absolute pressure, differential pressure, flow and level.
Through PROFIBUS PA, the Sitrans P DSIII is connected with
a Simatic S7400 controller that triggers a safe shutdown.
In the case of 'redundant/diverse' design, measuring circuits
up to safety level SIL3 can be established. With the Simatic
PDM configuration tool, Sitrans P DSIII is started up as a
regular PROFIBUS-PA device and then the PROFIsafe safety functions
are activated. The files required for this are at: www.siemens.com/sitransp.
Also new are Sitrans TH head mounted temperature transmitters
which communicate via Hart or PROFIBUS PA, or stand-alone.
