DEBUNKING THE MYTHS
An ongoing, lengthy discussion in a Control.com
blog has highlighted the question of what's 'open' and what's
'free'. Michael Griffin wrote about Ethernet/IP on 6 April,
2008: "It's not just that you have to pay for the spec.
It's that the specs are available only to 'qualified vendors'.
In other words, Rockwell's marketing department decides case
by case whether it is to their advantage for you to be able
to talk to their equipment. It is a very closed, very proprietary
protocol just like PROFINET."
Response: For the Ethernet/IP
response, you'll have to look elsewhere. Here we want to debunk
the idea that PROFINET is a "very closed, very proprietary
protocol." The PROFINET spec is published as an International
Standard by IEC so it is 'open' and can be used by anyone.
There is a cost, but that's normal for international specs.
In our case, the wide choice of development tools shields
you from having to actually own the PROFINET spec. Become
a member of our organization (only $550 for developers with
fewer than 10 employees) and you get lots of additional help
too. For example, the PROFI Interface Center in Johnson City
provides free consulting support to developers of products.
Other benefits include the chance to certify your product
- mandatory in the case of PROFINET because of the critical
importance of interoperability - and then you can use the
logo on products to prove you are compliant. Finally, you
get to be a member of the largest fieldbus community in the
world and have your products promoted on-line, in this newsletter
and elsewhere. All of which is a low-cost, excellent-value
way to get on board with PROFINET ... and surely a small price
to pay for the best Industrial Ethernet technology in the
PROFINET PASSES 1 MILLION - AND IT'S
CONFIRMED INDEPENDENTLY!: In a significant press conference
at Hannover Fair in April, new PNO Chairman
and PI Chairman-designate Joerg Freitag (right) announced
that by the end of 2007 the number of installed PROFINET nodes
had reached 1.14 million. He told journalists that the numbers
had been collected by an independent 'notary' (a lawyer mandated
to do this kind of work) and that vendors taking part had
submitted their individual numbers in confidence. "Only
the total is known to PI," he said.
These are the first 'official' numbers to have emerged from
our marketplace, he added. Furthermore only automation devices
such as PLCs, remote IO stations, HMIs, robots, proxies, drives,
and sensors were included. Devices like switches, hubs and
peripherals (e.g. printers) were omitted. At the press conference
a journalist asked: "How do other organizations count
their numbers?" "We don't know," Freitag replied,
"you'll have to ask them!"
PI will update the numbers at regular intervals to show the
ongoing success of PROFINET. It is expected that 3 million
nodes will be reached by 2010.
Freitag also announced that PROFIBUS sold 4.5 million nodes
in 2007, bringing the total to 23 million. "We're well
past 24 million today and expect to reach our next target
of 30 million before 2010," he said.
These latest numbers, he commented, send out a very strong
message to the market about the reality of PROFIBUS and PROFINET
solutions. "PROFIBUS is the most successful fieldbus
of all time - in all industries - and PROFINET is on its way
to replicating that success!" The growth curves are almost
identical, he added, so we feel confident that PROFINET will
prove to be the most successful Industrial Ethernet of all
Frietag: Asked: 'How do other
organizations count their numbers?' Freitag replied: "We
don't know. You'll have to ask them!"
IO-Link INTEGRATION WITH PROFIBUS AND
PROFINET: PI has published the specification for integrating
IO-Link into PROFIBUS and PROFINET systems. IO-Link is a fieldbus-independent
connectivity method for intelligent sensors, designed to bridge
the last meter between an IO block and the device, using conventional
wiring but superimposing digital communications. Aimed at
new generations of intelligent sensors - but retaining full
compatibility with older types - IO-Link allows configuration
and diagnostics to be performed from an engineering station
instead of at the sensor. Almost all sensor manufacturers,
and a host of manufacturers of I/O modules, have introduced
IO-Link products. The new documentation facilitates the integration
of IO-Link in PROFIBUS and PROFINET systems. The physical
layer and protocol specification of IO-Link is independent
of PROFIBUS and PROFINET so IO-Link can be subordinated to
all fieldbuses and Ethernet-based systems. Work to integrate
IO-Link into additional fieldbus systems is already underway.
An independent device description for IO-Link, (IO Device
Description, or IODD), is also under review. IO-Link
Integration Part 1.
ONE DAY TRAINING EVENTS: The
PTO and PROFI Interface Center training classes continue apace.
Classes center on PROFIBUS, PROFIBUS in the process industry
and PROFINET. Attendees receive a certificate for 5.5 Professional
Development Hours (PDH) and PTO raffles a week-long Certified
Network Engineer Class (a $2695 value) at each PROFINET event!
The table below summarizes upcoming classes. There's more
on the web here.
If we're not coming to a city near you with our training then
join us for our brand new webinar series. PROFIBUS in the
Process Industries will be the theme of our first four events.

PROFINET DEVELOPER WORKSHOPS:
PTO also sponsors a series of PROFINET Developer Workshops
at no charge. Targeted at developers and marketers of control
devices each free half-day workshop
provides an explanation of the PROFINET development tools
available. Prior attendance of one of the Training Classes
(the next one is in Scottsdale AZ, see above) is mandatory.
Topics covered: Following a brief
overview of tool types, nine development tools are introduced.
Development tool providers Altera Corporation, Grid Connect,
Inc., Hilscher North America, Inc., HMS Industrial Networks,
Inc., IXXAT, Siemens Energy & Automation, Real Time Automation,
Softing North America and Molex are available for consultation.
Each has a unique approach. The workshop will help determine
which tools suit your needs.
FAIR - FROM A PROFINET-TER'S POINT OF VIEW: PROFIblog,
the PTO's center of gravity in cyberspace, has focused a lot
on Hannover Fair of late. Carl Henning, PTO's Deputy Director
(that's him, left) spent a lot of time tracking down PROFIBUS
and PROFINET stories. In the Blog he presented his own take
on many items of interest at Hannover, including IO Link (it's
finally come of age, says Carl), news about two
more PROFINET masters (does any other IE technology have
more than one? he asks), and even a video of the Wednesday night
booth party (a Hannover tradition, with nice beer and music).

STRATEGY WHITE PAPER: At an
International meeting held during Hannover Fair, PTO Executive
Director and PI Acting Chairman Mike Bryant met with Regional
PROFIBUS Association Chairman and personnel from Italy, Brazil,
Switzerland, Belgium, France, Germany, UK and North America
to discuss key topics. He unveiled two important White Papers,
the first about PROFIBUS and PROFINET and their very close
strategic relationship. Many observers believed that Industrial
Ethernets like PROFINET would supplant fieldbuses, such as
PROFIBUS, years ago. Not so, said PTO, PI and PNO in unison,
though few people listened. (If you are a skeptic, take a
look again at the figures quoted above
for evidence that it is just not true.) PROFINET was designed
to be fieldbus-friendly (not just for PROFIBUS, but also all
the other fieldbuses you'll likely come across) and, further,
to utilize as many common features with PROFIBUS as possible
- for example common engineering concepts, and common PROFIsafe
and PROFIdrive profiles. The result, says the White Paper,
is a powerful automation combination offering the modularity
and flexibility needed to automate, evolve and update all
kinds of manufacturing plant easily. Not all features have
to be used at once, enabling users to choose what to deploy,
and when. The next full meeting of RPA Chairman takes place
in Tokyo on May 27th/28th.

THE PERFORMANCE OF PROFINET: The second White Paper unveiled
at Hannover Fair explains how PROFINET's performance in simple
line structures with small data messages can be enhanced. By
minor changes to the way PROFINET handles Ethernet telegrams
it's possible to improve the performance substantially. A demonstration
system was shown at Hannover Fair. Download

ROUND TABLE FOR PRODUCTION SECURITY:
Leading representatives of German industry, including PNO,
PTO's sister organization in Germany, represented the Security
in Automation steering committee in February for an
exclusive round table talk at the premises of
the German TV station ZDF in Berlin. The committee is a panel
of leading industrial associations, of which PNO is a member
along with ZVEI, VDMA, NAMUR, SecIE and VDI/VDE.
The importance of IT security for manufacturing industries
and OEMs was the main topic. Companies taking part included
BMW, Bayer and Nestle from the consumer goods industry, Lenze
and Siemens from automation and Victoria, an insurance company.
Valuable feedback about insurance and liability was shared.
The damage caused (both self-inflicted and from third parties)
is difficult to estimate and obtaining adequate insurance
cover is particularly difficult.
All participants agreed that Ethernet in the production arena
will require additional measures to guarantee IT security.
These have to cover both the automation and the IT level,
as the management level of the enterprise is now functionally
linked with automation. Measures related to production staff
are of importance because lack of knowledge amongst personnel
is very often the cause for security-related failures. This
means that both technical and organizational measures need
to be defined and communicated to everyone in a manufacturing
enterprise in the form of strict company policies that are
PI has always considered security to be critical and has
published a document called the PROFINET Security Guideline
- to help. The PROFINET security concept meets the requirements
of network security for Ethernet-based automation systems
in manufacturing. The concept fulfills the demands for access
control, data encryption, authentication and the logging of
security relevant events. Find the Security Guideline here.
FOUR NEW PROFILES: Four new
profiles have been published to suit specific application
domains for PROFIBUS and PROFINET. These are:
GENERAL ASSEMBLY MEETING UPCOMING:
PTO's annual General Assembly Meeting (GAM) is scheduled for
August 5-7 at the Marriot at McDowell Mountains in Scottsdale,
AZ. PTO invites all members to attend what is an informal
but highly educational and valuable networking event. End
users are particularly invited to present their stories -
if you're a user and would like to take part. A PROFINET Training
event and a PROFINET Developer Workshop take place on the
two days preceding the GAM - Training on August 4th and the
Workshop on the 5th. You must attend the Training day to qualify
for the Workshop. Details
of the GAM here.
BOARD MEMBER: The PTO has appointed Victor Wolowec (right),
Vice-president, Solutions Business at Endress+Hauser, to its
Board. Mr. Wolowec will be replacing Todd Hubbell, who was recently
promoted to Vice-President of Logistics at Endress+Hauser.
We are genuinely sad to see Todd leave the PTO Board
of Directors," said Michael Bryant, Executive Director
of the PTO. "He has been an ardent supporter of the PTO
for many years and has contributed greatly to our success
during his tenure. We are extremely happy about his Endress+Hauser
promotion and will surely miss him. Bryant adds: We
welcome Victor to the PTO Board and look forward to many successful
years' of his participation."

The Japanese PROFIBUS Organization (JPO) held two further
PROFINET seminars for developers in March, attended by 65
engineers. PROFINET seems to be one of the most powerful candidates
for future plants, so there is great interest among Japanese
engineers. JPO members - among them Hilscher, HMS, Softing,
Siemens and Woodhead - made presentations about their development
tools. UK: The program for the
PROFIBUS and PROFINET User Conference 2008 has been published.
In May, PNO UK members are helping users learn how to simplify
their PROFIBUS automation application with a one-day seminar
called Practical Aspects of PROFIBUS in Factory Automation.
Ireland, in cooperation with ISA Ireland, held a technical
talk on PROFIBUS technology in February. ISA Ireland has invited
PROFIBUS Ireland to hold a similar presentation at their annual
exhibition and seminar. SOUTHERN AFRICA:
At the recent Annual General Meeting, outgoing Chairman Dieter
Dilchert reported on the organizations achievements
in the past months. The newly-established Automation Training
Council has now trained more than 60 students. Edwin Bauer
of ABB follows Dieter as Chairman. SOUTH
EAST ASIA: For the first time, PROFIBUS South East
Asia has visited Vietnam, at the Processing Instrumentation
and Analysis & Lab event in Ho Chi Minh City. GERMANY:
The first PROFINET workshop of this year took place in February
at Würzburg with more than 40 participants. HMS, Hilscher,
Siemens, TMG TE, Gleichmann Electronics, KW Software and Softing
presented their support products.
SWITCHES: The SMCS 6GT/2SFP Smart Managed Switches
from Phoenix Contact have Gigabit Ethernet ports and also
fiber interfaces. Gigabit performance leads to excellent real-time
properties for use in PROFINET RT networks. At the same time,
IT real-time services such as video or Voice-over-IP can be
implemented with high levels of data throughput. The switches
have two optical interfaces for which segment lengths can
be up to 70 km. The switches are compatible with PROFINET
engineering tools. A pluggable configuration memory with M12
connectors lets you easily exchange devices. PHOENIX
MANAGEMENT WITH FDT: AssetView
is an asset management system supporting PROFIBUS, using simultaneously
EDDL and FDT/DTM. From a list of configured PROFIBUS field
devices its possible to access directly the DTM for
the chosen equipment, making parameterization, uploads, downloads,
etc. very simple and fast. Operators can perform maintenance
through scheduled programming routines, including notifications
by e-mail, without needing specific software. AssetView also
allows the inclusion of the equipment in a library that contains
datasheets, manuals, maintenance procedures, notes, pictures
and internet links for their vendors. SMAR.
API: PROCENTEC has a master API for its ProfiCore product
which makes it possible to personalize applications for PROFIBUS
DP. Anyone with C++ or Visual Basic knowledge can now control
their processes exactly as they want. It uses technology from
ProfiCaptain to exchange data with nodes in the DP network.
Now, for example, it is possible to periodically control the
I/O of the nodes and view it on-screen. Automated maintenance
tasks can be easily performed from the control room: the Scan
Network or Steal slave concept can be part
of the application. This provides enormous flexibility in
any PROFIBUS DP network. The API supports DP-V1 and is free
of charge for ProfiCaptain users. GRID
ANALYZERS AND TESTERS:
Softing has new firmware versions of its PROFIBUS Protocol
Analyzer V1.20 and its PROFIBUS Electrical Tester PB-T3 V1.50.
The new versions are available as a free download from Softing's
web page. They enhance the Analyzer to concurrently
analyze and cross-check PROFIBUS DP and PROFIBUS PA networks.
Softings Electrical Tester PB-T3 is designed to automatically
analyze communication problems based on electrical issues.
It is also is the only tool able to determine a PROFIBUS DP
topology. The PB-T3 also displays the average signal level
for each device and, more importantly, the minimum and maximum
deviation from this signal level. Many puzzling communication
problems can be traced back to sporadic changes in signal
TURCK has a new BL67 Ethernet gateway for PROFINET. I/O modules
are configured independently of the fieldbus, and up to 32
I/O modules may be connected to a gateway. This means systems
may include up to 512 digital I/O or 128 analog channels.
All BL67 systems use TURCKs free I/Oassistant software
package to perform the initial configuration, parameterization,
documentation, commissioning and diagnostic functions. It
is recommended to use I/Oassistant to verify that all restrictions
regarding power and size are met. I/Oassistant can be downloaded
for free. The PROFINET BL67 gateway is compatible with TURCKs
RFID system. TURCK.
