Sweet SUE has shown her face yet again!
While on vacation in her home island of Jamaica,
Pretty Polly (left) noticed a new on-line White Paper trumpeting
some alleged 'truths' about Industrial Ethernet. The document
is called 'Evaluating Industrial Ethernet: What is Standard?'
and in it the author revives memories of our very own Sue
(see right, middle).
SUE (Standard Unmodified Ethernet), says the
author, comprises the officially defined Ethernet (IEEE 802.3),
the TCP/IP/UDP suite and application layer protocols such
as SMTP, HTTP and others. Nothing more and nothing less is
allowed and anything that by-passes/adds to/subtracts from
this cannot be SUE. Special chips are roundly condemned and
non-COTS hardware should be avoided at all costs, says the
document. Well, that rules out all Industrial Ethernet protocols
The author - a Rockwell Automation employee
of course - dredges the depths of pedantry to find fault with
every Industrial Ethernet solution except his own!. Surprise,
surprise. The document bundles PROFINET into the 'non-standard
Ethernet' group, which makes it bad, bad, bad! What
Isn't it about time this stupidity stopped?
Otherwise, we'll have to dust off our own 'Pretty Polly, Sweet
Sue and the White Knight' document and start waving it about

GENERAL ASSEMBLY MEETING: The
PTOs 14th annual General Assembly Meeting (GAM) in Scottsdale,
August 6th/7th, attracted 70 delegates, including representatives
of over 50 North American member companies. A great series
of presentations was organized, with User Experiences
(of both PROFIBUS and PROFINET) interspersing technical updates
and marketing presentations.
Executive Director Mike Bryant (pictured
right) explained that the 25 million PROFIBUS nodes now installed
were probably only the start: 30 million is easily achievable
now, he said, and who knows where it will end?
At current rates even 50 million is within our grasp. What
a great foundation that is for PROFINET, which is now also
taking off nicely. He urged members to take advantage
of the great commercial opportunities offered today by PROFIBUS.
A open topic throughout the meeting was whether PROFINET
might cannibalize PROFIBUS sales, or vice versa. The feeling
was that although there will eventually be an evolutionary
change, nothing could be lost now by promoting PROFINET hard.
In fact the wonderful partnership offered by PROFIBUS and
PROFINET together was part of the marketing magic of the two
technologies. Just go for it! was the consensus.
Collaboration Corner covered
the role that PI - that's PROFIBUS and PROFINET International,
PTO's parent organization - plays in international efforts
to bring key automation technologies closer together. Ron
Helson (right) of the HART Communication Foundation described
WirelessHART and how the Wireless Cooperation Team (WCT) is
developing an interface to allow fieldbus technologies like
PROFIBUS and PROFINET to easily and quickly bring WirelessHART
data directly into automation networks.
Among the end user presentations was
one by Merat Zarreii of the DeKalb County Department of Watershed
Management, Georgia, pictured right, who described how his
decision to deploy PROFIBUS plant-wide had resulted in dramatic
savings in manpower, time and costs. PROFIBUS in Mining (actually
on the big machines used in mining applications) was the topic
of another end user presentation, this time from Todd Preder
(below, right) of the Professional Control Corporation. PROFINET
apps in a cigar plant and a water extraction facility were
The GAM included 'table tops' and
was preceded by a PROFINET Training Day and a PROFINET Developer
Workshop. The main event delivered plenty of networking opportunities,
including some fun time courtesy of PTO and a pool party at
Casa de Bryant on the last evening.

PIC 'CONNECTION': The latest
issue of the PIC 'Connection' magazine features a brand new
PROFINET story about the control of hydraulic drive technology
metal-forming machines, which is one of the most demanding
of motion control applications. Among other things, it requires
quick and precise control of rams and bed cushions, together
with a distance, time or process-dependent use of speed and
pressure profiles. Travel movements in pressure-controlled
hydraulic presses are very demanding because of the 'flying
transition' from position regulation to pressure regulation.
In the instant when the tool strikes the workpiece, an extremely
dynamic progression of forces occurs, which must be regulated
using the bed cushions. It may also be necessary to follow
a pre-defined pressure profile. In the application described,
the controllers of the individual modules in a strip line
are linked to each other using PROFINET with IRT. The deterministic
exchange of the set position values and actual position values
via IRT telegrams permits exact synchronization of the axes.
There's a host of other good stuff in 'Connection' too.

TRAINING IN TROUBLESHOOTING:
PROCENTEC and Grid Connect recently organized a PROFIBUS Troubleshooting
& Maintenance training course in Atlanta, USA. For two
days, 17 participants were trained in solving problems in
PROFIBUS installations using the latest tools such as ProfiTrace
2. More and more factories in the USA are using PROFIBUS as
their standard automation system and there is a big demand
for training. Another session will be organized in October
COMPETENCE IN PROFIsafe DESIGN:
The next three-day PROFIsafe Training Workshop has been announced
by PNO, PTO's sister Regional PI Association in Germany. It
will be held in English and PNO is inviting North American
delegates to attend. The date is October 28 - 30, 2008, in
The Training Workshop recognizes the importance of 'competence'
in functional safety matters, and has been developed by the
responsible PI working groups in cooperation with TÜV.
The three day session includes a written test at the end of
each day. Delegates having passed all tests will receive a
TÜV certificate entitled 'Certified PROFIsafe Designer'.
The training must be repeated every second year to keep the
required level of competence up-to-date. More
Two PROFINET case studies this time:
EXTRACTION WITH PROFINET: ITC in Belgium has completely
renewed the operation of its water extraction activities,
choosing Phoenix Contact to supply the control units and decentralized
modules that control various wells and pumps. The exchange
of data between the modules and the PLC is done via PROFINET
using an existing Ethernet infrastructure.
ITC is part of the Balta Group, one of the leading manufacturers
of floor coverings worldwide. Water, one of its most important
raw materials (it's needed for making paint), is extracted
from 28 wells distributed throughout the company. Previously,
these were controlled by a 25-years-old central control unit,
which used masses of cables and did not comply with current
standards. ITC therefore set about looking for a new partner
to supply a modern PLC-based system.
Water extraction is now controlled by an ILC 350 from Phoenix
Contact, with twelve slaves keeping track of, and operating,
a number of wells each. The slaves exchange I/O data via PROFINET
with the master PLC, which activates pumps according to input
signals such as low buffer tank water levels, a sudden drop
in pressure, or various other alarm conditions.
With the Phoenix Contact system, a malfunction is detected
immediately by a reader in a slave and directly signaled through
to the central control unit, which then alerts intervention
teams by sending out e-mails and SMS messages.
Bonte, (left) head of the Electrical Department at ITC, said:
In the factory, we have a classic Ethernet network.
A few years ago, we replaced all our office hubs with Ethernet
switches and optical fiber. Therefore, switches were already
available in the vicinity of the wells. The connection of
a short cable between switches and I/O ports was all that
was necessary during the upgrade. Thanks to PROFINET, we have
been able to reap more benefits from those earlier investments
in switches. We did consider facilitating communications between
the PLCs using classic Ethernet. However that was more complex
to program. PROFINET is easier to integrate. We know we are
not using the full real time potential of PROFINET but the
benefits have been worthwhile nevertheless.
COGNAC WITH PROFINET: The most important line at Hennessys
La Vignerie bottling plant for VS and VSOP cognac, has been
fitted with a redundant PROFINET CBA network linking sub-systems
based on PROFIBUS and SIMATIC S7-300 PLCs. Control components
on the line exchange up to 200 data words over the network
with a guaranteed cycle time of 50 ms. This facilitates a
connection to the corporate Ethernet, enabling easy integration
with individual modules of the Hennessy SAP ERP management
The line consists of three conveyor systems and eight production
machines based on PROFIBUS, each controlled with S7-300 PLCs,
and fitted with CPU 315-2 PN/DP interfaces to connect them
to a redundant PROFINET ring via SCALANCE X204-2 switches.
The first conveyor also has an X202-2IRT switch which controls
ring redundancy and self-restoral.
Configuring information exchange is straightforward. With
PROFINET CBA, engineers can insert, swap or connect individual
machines simply by dragging and dropping them in a graphical
display leading to significant time savings not only
during the design phase but also when setting up the communications.
The CBA solution has also achieved high reliability and improved
The recent Conference was an unqualified success, with over
70 delegates attending two days of seminars, workshops and
presentations. Chairman Bob Squirrell attributes the success
to focusing on Users. User attendance was up - particularly
from the Process and Water industries. The Conference will
be back at Stratford Manor again in 2009, on 16th and 17th
June. Separately, the PICC at Manchester Metropolitan University
has certified the first UK PROFINET engineers. CHINA:
The China PROFIBUS User Organization (CPO) attended the 12th
International Exhibition of Modern Factory/Process Technology
and Equipment (2008 FA/PA) held by the China Association for
Mechatronics Technology & Application (CAMETA) on June
10-13, 2008 in Beijing, China. BRAZIL:
Cesar Cassiolato from SMAR has been re-elected as President
of the Brazil Latin America Regional PROFIBUS Association.
He and fellow RPA directors Marco Aurélio Padovan from
SENSE and Jomar Misseno from SIEMENS, (both re-elected until
2010) have increased the membership of the PROFIBUS Association
by 40%. They also founded the first PROFIBUS Competence Center
in Latin America. SOUTHERN AFRICA:
The Automation Training Council in South Africa, established
as a joint effort between the Southern African German Chamber
of Commerce and Industry and the PROFIBUS User Group of Southern
Africa, has now trained 61 students since August 2007. In
addition, 9 lecturers at South African educational institutes
have benefited. In effect, this means that 7 local educational
institutions now have a base of cutting-edge lecturers. This
all has been made possible by initial funding from the German
Federal Ministry of Co-operation and Development through its
agency SEQUA. Local companiesSiemens, ABB,
Lapp Cable and IDX Onlinehave also supported the initiative.
POLAND: The Polish RPA has reported
on a successful experiment to set up a distributed PROFINET
CBA system straddling three countries and connected via the
Internet. Poland, neighboring Germany and Norway hosted the
experiment, with three universities collaborating. A PLC in
Germany controlled a small pick and place robot. In Poland,
a second PLC was used to control this robot using the internet
and PROFINET CBA. In Norway, a SCADA station visualized movements
of the robot and measured the delays in transmitting data
across the internet. The tests showed that acyclic data transfer
could be accommodated within 1000 ms, meaning that PROFINET
CBA can be used for visualization and parameterization over
the internet. ITALY: In July
the 2nd PROFIBUS Product Developer Training Class took place
in BRESCIA (Italy) at the PROFIBUS Competence Center (PICC)
at CSMT Gestione Technological Center in the Campus of the
Brescia University. Around 45 engineers learned how to undertake
a PROFIBUS product development project. SWEDEN:
The Swedish RPA will attend the PROCESSTEKNIK Conference in
Gothenburg in October. The Swedish web site is also undergoing
an extreme makeover with the goal to reach every
aspect of PROFIBUS and PROFINET with no more than 3 mouse
CARD: This PCI / PCI Express IO-Controller card for
PROFINET provides high-speed deterministic communication between
control / SCADA applications and IO-devices. It is packaged
with a Windows software suite including configuration console,
diagnostic tools, library DLL and OPC server. A network detection
mechanism is able to discover and build a network topology
based on the integrated GSD device library. Acting as an IO-supervisor,
the console allows each device to set the name and IP address
for each IO-device. OS driver kits are available free-of-charge
for Linux, VxWorks, QNX and other platforms. MOLEX
MASTER FOR COMPACTLogix: ProSoft Technology's new single-slot
PROFIBUS DP V1 Master (PS69-DPM) and Slave (PS69-DPS) modules
are backplane-compatible with the CompactLogix platform. Master
DTM is included for FDT Asset Management, with support for
FDT-compliant containers such as PACTware or FieldCare. The
Master module supports both I/O control and CIP messaging
for slave parameterization, and acyclic DP-V1 messaging via
explicit ladder logic message blocks, status data and alarms.
For configuration, both modules use PROSOFT.fdt Configuration
Software, or the slave module can be configured via ladder
logic. Both modules are PROFIBUS certified and Encompass Approved.
One of Softings PROFIBUS boards was customized to fit
into a subsea production component designed by Aker Solutions,
Scotland and has passed the stringent quality requirements
mandated for use in subsea production systems. Softings
PROFIBUS board is integrated into an active electronic module
that is part of a so called 'Christmas Tree', an assembly
of valves, spools and fittings for an oil well. Aker Solutions
rigorously evaluated numerous vendors that offer PROFIBUS
components and decided to partner with Softing because of
the availability of a PROFIBUS board that satisfied the functional
and quality requirements and Softings ability to perform
the required customization in an extremely short time frame.
The new unit was subject to a rigorous qualification process
with respect to mechanical shock, vibration, thermal shock,
storage and operational temperatures. SOFTING
ANALYZER FOR PROFINET:
Hilscher has launched a PCI-based network analyzer designed
for use with Real Time Industrial Ethernet protocols such
as PROFINET RT/IRT. Network traffic can be time-stamped within
a 10ns resolution to provide accurate information about jitter
and delay times for individual nodes. The netANALYZER is controlled
by Wireshark and it provides 4 full duplex ports thus allowing
the measurement of traffic into and out of a node. With these
features netANALYZER is capable of measuring the network response
of high performance drives and motion control products based
on the IEEE 1588 specification. HILSCHER
CONTROLLER: The new RFC 470 PN 3TX is a DIN rail-mountable
compact control system providing up to five direct inputs
and three direct outputs, designed for universal applications
in machines and systems. It's programmed and parameterized
with PC Worx software. Status messages of the control system
and fieldbus system are easily displayed via the TFT diagnostics
display. As part of the concept of IT-powered automation,
the RFC 470 PN 3TX provides open automation and IT interfaces
for communication. In addition to an Interbus master and a
PROFINET controller interface, three 10/100 Mbps Ethernet
interfaces ensure easy integration of the system into plant
networks. Productivity can thus be increased significantly.
UPDATES: MESCO has updated its IO-Link Slave Stack.
All specification options are now included, such as Service
PDU for transferring large amounts of application specific
data, the Interleave Mode for up to 32 byte process input
and output data transfer, and Extended Diagnostics/Events.
The package consists of documented Source Code written in
ANSI-C, an application example and detailed development documentation
with a hardware porting description. Slave evaluation boards
and a complete IO-Link Starter Kit are already available.
Key components include the slave firmware stack, hardware
modules plus schematics both for Master and Slave Devices,
plus an IO-Link monitor and environment for test and commissioning.
The kit will be released in November at the SPS/IPC/DRIVES
PC HAS PROFINET: Siemens has equipped the mainboards
of its ruggedized industrial PC family with a PROFINET interface.
Using ERTEC 400 the PC now incorporates a three-port switch
and supports isochronous real time operations. It also enables
simultaneous real-time and IT communication on one line using
TCP/IP. Integrating the interface relieves the processor of
communication tasks and increases system performance. It also
saves an expansion slot. Three ports allow flexible deployment
of linear or ring topologies and facilitate the connection
of PLCs, distributed I/O and drives. Alternatively, they can
be used for visualization. WinAC RTX 2008 already uses the
new communication facilities and the network can be configured
with Step 7 or NCM-PC. SIEMENS
The new ProfiTrace 2.1 tool can generate the topology of a
PROFIBUS network without shutting down the installation! The
Topology Scan is a new feature of ProfiTrace 2. It generates
a clear network drawing that contains the location of the
devices and length of the cable that links them. This new
feature makes ProfiTrace the most complete PROFIBUS tool available.
More and more end-users and manufacturers are standardizing
on ProfiTrace as the default troubleshooting tool for their
