GENERAL ASSEMBLY BRINGS FOCUS ONTO FUTURE
The 2006 PTO (North American PROFIBUS organization) General Assembly meeting took place in Scottsdale, AZ, in August. Over 50 members and representatives listened to wide ranging discussions about technical and marketing issues, and the future strategy of the PTO and its parent organization, PI.
PTO Chairman and PI Deputy Chairman Mike Bryant (pictured) said that being market leader posed some challenges: 'We must watch out for new technologies and paradigm shifts, and we must never forget that our competition is always biting at our heels,' he said. 'Complacency could be our biggest enemy.'
The broadening technical scope of the organization - now ranging from sensors to IT - means we have to adapt. 'PROFIBUS will continue to be the most successful fieldbus ever,' he said, going on to predict that 30,000,000 PROFIBUS devices will be installed by 2011.
He warned: 'PROFIBUS growth will eventually flatten so we must face those challenges now.'
Mike also predicted a shakeout of Ethernet solutions within 5 years, with just 3 serious contenders remaining and said that PROFINET has moved from being a fieldbus technology to an 'automation technology', with all that entails.
He concluded by announcing a new mission statement for PI, the international organization of which PTO is part: 'We are and will remain the world's leading automation organization for communication solutions, serving our users, our members and the press with the best solutions, benefits and information.'

PI would like to invite you see the very latest and best of PROFIBUS and PROFINET at what is fast becoming one of the best events in the worldwide automation calendar: the SPS/IPC/DRIVES show in Nuremberg, which this year is taking place from November 28th to 30th.
Interbus and PNO will be exhibiting side by side once again with a joint booth and hospitality suite. On the PNO side about 40 co-exhibitors will lead you through topics such as IO-Link, PROFIBUS and PROFINET.
One of the highlights will be a huge PROFINET presentation but there will be something for everyone, whether end user, manufacturer, developer, integrator, maintenance engineer, or a 'decider', PNO will answer all questions and deliver what for you could be a vital insight into the exciting and dynamic world of PROFIBUS and PROFINET automation.
SUPPORTING PROFINET
Three major Japanese Companies - Toshiba, Hitachi High-Tech Trading and Fuji Electric Systems - expressed support for PROFIBUS and PROFINET as JPO members at a recent Japanese press event. Toshiba said that PROFIBUS fits its target because it covers both factory and process automation while Fuji Electric has promised future support for PROFINET in its system. More: see 'Japan' story below.
PROCESS MANAGEMENT ACADEMY
PI will support the Process Management Academy at Neuss, Germany, Jan 22-24, 2007. The event is organised by ARC Advisory Group. PROFINEWS 53 will give details. More here:
CERTIFICATION: WHAT IT MEANS
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 at 'Downloads' on the PI Website. Thus, users can get the necessary security for error-free functionality during the common operation of devices of different manufacturers. Similarly, the certification ensures the 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.
SUPPORT, TOOLS AND USEFUL LINKS
PITLs for PROFINET are PI Test Laboratories for PROFINET devices.
PITLs for PROFIBUS are PI Test Laboratories for PROFIBUS devices.
PICC for PROFINET and PROFIBUS: PI has accredited a global network of PI Competence Centers, where engineering support like product development, trouble shooting or similar is offered, seminars and training courses are held, and experts answer technical questions.
Software and tools: Helpful software and free tools like an XML Viewer, Ethereal (Wireshark), a test tool for PROFINET CBA, a Component Editor, a GSD-Editor, an I&M Functions Demotool, etc. can be found on PI's website here.

PNO WELCOMES CHINESE FRIENDS
Zhang Dandan and Zhang Wei at a medieval feast in Germany
In August, 2006, both Zhang Wei and Zhang Dandan, two members of staff from the Chinese PROFIBUS User Organization (CPO), were invited by PNO in Germany for one month to learn about the workflow of PNO and exchange ideas. They received not only a warm welcome from PNO but also much detailed information about training and other aspects of PNO.
The staff of CPO learned about the success of PNO and PI in terms of workflow, technology promotion and events organization, experience that will prove highly beneficial to CPO and its members. This will enable CPO to better develop the Chinese market, strengthen the leadership of CPO in the PROFIBUS world and extend the influence of PROFIBUS and PROFINET in the Chinese market.
QUESTIONS ANSWERED
Question: Can you summarise the differences between Industrial Ethernet and PROFINET?
Answer: 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?
A: 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: 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:

PICCs AND PITLs MEET IN SWITZERLAND
PI Competence Centers (PICCs) and PI Test Labs (PITLs) from Switzerland, China, Czech Republic, France, Germany, Ireland, Italy, Japan, the Netherlands, Poland, South Africa, US, and United Kingdom sent delegates to the recent Competence Center and Test Labs Meetings at Winterthur, Switzerland.
Technical presentations were given on PROFIBUS and PROFINET, IO-Link, PROFINET for Process Automation, Explosion Safety, Installation, Troubleshooting, and other issues.
Quality assurance was an important topic of the meetings: 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 (see Page 2) and ensure that the certification tests fulfil the same standards worldwide.
Close cooperation between PICCs and PITLs ensures that information is exchanged quickly and regularly, and that all centers worldwide offer the best support. Many people believe that this close cooperation in 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.
Soon, choosing a seminar will be even easier: PI has decided to certify PI Training Centers. The next PROFINEWS will tell you more about this new aspect of PI's global support network.

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!
The conference was hosted by Mrs. Wang Jun, the Secretary General of CAMETA (China Association for Mechatronics Technology and Application). Keynote speakers included Mr. Edgar Kuester, Chairman of PI (PROFIBUS & PROFINET International), Mr. Lee BaiHuang, the Chairman of CPO and Mr. Tang Jiyang, Director of CPCC (China PROFIBUS Competence Center), who gave presentations on IO-Link, PROFIsafe and PROFINET.
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. Mr. Motoyoshi of JPO described the status of PROFIBUS and PROFINET. Seven members of the media were present.
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. The speakers were Josef Schmitzer of Siemens, Peter Engelhardt of Phoenix Contact and Thomas Schildknecht, CEO of Schildknecht. Discussions centred on PROFIBUS, PROFINET and PROFIsafe.
The speakers made a particular effort to emphasise the important differences between current commercial wireless networking solutions and the very special needs of industrial wireless communications. Immunity to interference, determinism and reliability were also subject of robust debate as delegates familiarised themselves with the potential of wireless communications. A number of key applications were presented. Hosting the function on behalf of PUGSA were Dieter Dilchert of Lapp Cable/Integrate & Autom8 and Edwin Bauer of ABB.
UK
PROFIBUS UK has announced a new seminar for technicians and engineers involved in the design, operation and maintenance of modern process plants. Addressing key practical aspects arising from the use of digital fieldbus communications in process and hybrid industries, it covers the use of PROFIBUS PA in applications such as Pulp and Paper, Chemicals, Utilities, Pharmaceuticals and Oil and Gas. A downloadable registration form can be found here. Meanwhile, 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.
NETHERLANDS
On 27 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. The aim was to learn about latest developments. One speaker was Dr. Hasso Drahten, general manager of NAMUR, a major international organisation for process industry users which focuses on the specification and testing of field equipment. NAMUR has made a number of recommendations relating to fieldbuses. Herman Suselbeek spoke on behalf of WIB, a similar international organisation which works closely with SWE, EXERA in France, SIREP/EI in UK and NAMUR itself. He compared EDDL (Electronic Device Description Language) with FDT/DTM (Field Device Tool/Device Type Manager). In his presentation, Dolf van Eendenburg emphasised the importance of Lifecycle Costs as a criterion in opting for PROFIBUS. The benefits were explained using three practical examples: the new Gargill production plant in Russia, the Grolsch brewery in Hengelo and the new production control at Triton Kappa in Coevorden.
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'. (The audience agreed with that one wholeheartedly!)
Once again, it was stressed, long-term profits are being missed through short-term thinking. The PROFIBUS Breakfast was organized in association with ABB, Bayer Technology Services, Endress & Hauser, Imtech Automation Services, Krohne, MTL, Samson, Siemens, Turck and WIB International Instrument User's Association.

USA/ USER EXPERIENCES IMPRESS AT GENERAL ASSEMBLY
Michael Darnell of Prism Systems
End user presentations at the PTO General Assembly meeting in August (see also story above: ) covered applications in tobacco and, believe it or not, the theater. Michael Darnell, (pictured right) of system integrator and PTO member Prism Systems, spoke enthusiastically about PROFINET's 'component based' capabilities, which were put to good use in a plant making hundreds of different cigar products. The plant is highly automated mechanically but lacked 'electrical' automation, so the owners decided to bring things up to date and create a 'show place' for the industry, all to a tight time scale.
The plant comprises many identical machines and was ideally suited to the component-based approach, whereby one automation module (it can be a machine, a fieldbus network or a single device) is defined as a 'component', placed in a computer library and then re-used as often as needed.
Using simple click and drag techniques components are placed into an on-screen drawing and the communications paths are configured by simply joining up the inputs and outputs on-screen, a procedure that saves huge amounts of engineering time and effort.
The plant uses 21 PLCs, with extensive PROFIBUS and AS-Interface networks. The benefits, said Michael, are shown by simple mathematics: using conventional programming, it takes 80 hours to develop code for each machine and 4 hours to replicate it for each other machine, resulting in over 300 hours of effort for the 63 machines in the plant, plus a modification time of 10 hours every time something has to be changed. Using the component-based approach, the code takes the same time but replication is reduced to minutes, giving a total of about 90 hours. Furthermore, each modification takes only minutes and only has to be performed once because it is automatically made available to all the others. Among the advantages are easier project management and the ability to test and prove programs off-site.
The 4500 man-hour project was implemented in 5 months and showed a reduction of 20% in labor hours and 30% in labor costs. 'With component-based PROFINET,' said Michael, 'we were able to 'eat the elephant' easily!'
Jim Tomlinson of the MGM Grand Hotel and Casino, Las Vegas
Jim Tomlinson (pictured right) of the MGM Grand Hotel and Casino in Las Vegas fascinated the audience with a detailed explanation of how PROFIBUS and PROFIsafe are used in the Cirque du Soleil show 'KA'. The show involves non-stop action, both on-stage and front of house, with complex motion of stage parts and flying apparatus. 32 PLCs, 186 drives and 206 coordinated axes are employed. Safety is tightly integrated via PROFIsafe and, once begun, the show rarely stops even if a major problem develops ... 'we just slow it down a bit until things come back on track,' said Jim.
12 months advance testing of the KA system took place at a Canadian base before the show was set up in Las Vegas.
This user experience was a stunning demonstration of the power of PROFIBUS and we hope to bring you a more detailed case study shortly.
BRAZIL/ SUGAR + ETHANOL
The Alto Alegre Sugar and Ethanol Plant, Floresta unit, in Presidente Prudente city had an unusual challenge: apply new technology where efficiency was already high. Ethernet proved to be an answer, using Smar System302 function blocks and linking device technology which establishes local or external links with other Ethernet field devices.
38 field devices using 4 to 20 mA / HART were replaced by PROFIBUS PA devices, including pressure, level and density transmitters, valve positioners and current converters.
The new DF73 Master Controller headed the PROFIBUS PA architecture and field devices were distributed in six PROFIBUS PA networks, using Pepperl+Fuchs couplers, gateways and powerlinks. All devices were configured by PROFIBUS View, the Smar configuration tool. System 302's Process View is now the plant's supervisory system and all field devices were configured and commissioned using a new tool called Instrument Panel.
After startup, the user found the plant operated at the same high efficiency as before, but that other very useful characteristics had become available:
- Maintenance is no longer limited to control loops.
- New information about field devices is reached.
- Device replacement time and plant downtime are reduced.
In addition, the simplicity of the installation is helping keep up efficiency. It also brings easy maintenance and reduced footprint.
Wilson de Souza Castro Jr., Instrumentation Manager from Alto says that the update time of field data is reduced through the use of OPC. 'This is another successful application where an already-efficient plant could achieve further benefits using System302 features and Smar Technical Support Services. Alto Alegre Sugar and Ethanol Mill is getting the best of its process day by day. Smar should be very proud', said Wilson.
