DEBUNKING THE MYTHS

Barely into March and we are already thinking of presenting the 2008 Golden Polly Award to Rich Timoney of the Fieldbus FOUNDATION no less, who has published a comparison document identifying the alleged 'weaknesses' of PROFIBUS compared to FOUNDATION Fieldbus. It is full of classic parrot marketing, most of which we have de-bunked before - like 'PROFIBUS doesn't use Function Blocks!' So, let's put the record straight ... with no holds barred!

Myth 1: PROFIBUS now consists of three separate protocols grouped under the common umbrella name of PROFIBUS. These protocols are PROFIBUS-FMS, PROFIBUS-DP and PROFIBUS-PA

Response 1: No Rich, it's one protocol - PROFIBUS - which, unlike FF, is optimized for all kinds of instrumentation needs in both factory and process automation. PROFIBUS PA devices use the same protocol as DP. However, because of the 'Manchester Encoded, Power on the Bus' technology needed for hazardous areas, the PA Physical Layer (that's the cable to you and me) needs to be changed - hence the 'coupler' device that's involved. Being just a physical device it's not a 'gateway' either! FMS, by the way, faded into disuse 10 years ago.

The great advantage of the PROFIBUS method is that discrete-like processes (drives, motors, valves) AND process instruments like transmitters can exist on the same network, and be run from the same controller if needed. We call these 'hybrid' networks, and a very high percentage of process plants exhibit this requirement. FF has no solution, which is why PROFIBUS is so dominant in process (see below).

Myth 2: The largest percentage of applications is PROFIBUS-DP, and a very small percentage of the total is PROFIBUS-PA.

Response 2: Er, yes! But, FF and PA were running roughly neck and neck in process last time we looked - at about 600,000+ each - although when you add the 'hybrid' PROFIBUS devices described above it comes to about 4,000,000 for PROFIBUS. There are roughly 24,000,000 PROFIBUS devices out there in total - more than all the competition - including FF's contribution - added together! Oh, and don't forget that many process instruments use PROFIBUS DP, so the number out there with PROFIBUS definitely exceeds the number with FF!

Myth 3: In addition, there are a number of totally proprietary protocols that are called PROFIBUS.

Response 3: Utter nonsense, bilge and dirty dishwater. It's also wrong!

PROFINET DEVELOPER WORKSHOPS: In conjunction with the PROFINET training mentioned above, PTO is sponsoring 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. This workshop is conducted on the morning following the full-day introductions to PROFINET in Portland AND Cleveland, and prior attendance of one of those classes is mandatory. Please see the above table.

Topics covered: Following a brief overview of tool types, eight development tools are introduced. Development tool providers Altera Corporation, Grid Connect, Inc., Hilscher North America, Inc., HMS Industrial Networks, Inc., 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 ones suit your needs.

NEW USA TRAINING CENTER: RC Systems, in Johnson City, Tennessee, has been accredited as a PI Training Center for PROFIBUS DP and PA. RC Systems is owned by Ron Mitchell (right), whom many readers may know. Ron recently retired after twenty-four years with Texas Instruments and Siemens. For his last ten years with Siemens he was a member of the PROFI Interface Center (PIC) in Johnson City, actively involved in PROFIBUS promotion and support. Working in conjunction with the PTO, he has given dozens of PROFIBUS seminars. Ron was one of the original developers of the PROFIBUS Certified Engineer Class, which is now offered around the world, and he taught this class for the PIC for six years. He is also the author of the ISA book ‘PROFIBUS: A Pocket Guide’. RC Systems offers:

  • Product development advice
  • Network architecture design
  • On-site certification training
  • On-site maintenance & troubleshooting training
  • Network analysis and troubleshooting

NEW CHILEAN TRAINING CENTER: RP Ingenieria, located in Concepción City, in the south of Chile, has become an accredited PI Training Center. RP was founded in 2002 by Rodrigo Pinto Cárdenas, who writes:

"We are systems integrators, and a Siemens partner in Chile. Also, we are Procentec and Autem distributors. My company works a lot with PROFIBUS so I became a PI member in 2006 by joining PTO.

"The quality of the support received from PTO and the PIC led me to take the certified training course in 2006. I was trained by Ron Mitchell and John Swindall at the PIC in Johnson City, and I became a Certified PROFIBUS Network Engineer.

"PTO sponsored us to open our Training Center to help promote PROFIBUS in our country. We can give the Certified PROFIBUS Installer and the Certified PROFIBUS Network Engineer course in Spanish."

RP has a multi-vendor PROFIBUS demo with equipment from Siemens, Beckoff, Acromag, Telemecanique and Procentec. There's capacity for up to 10 persons on site. RP's PROFIBUS offer includes:

  • Scheduled training
  • Onsite training
  • Network architecture design (multi-vendor)
  • Network Troubleshooting and Analysis (multi-vendor)
  • Network components (cable, repeaters)
  • Network Analysis Tools (Profitrace II)

PROFIdrive STANDARDIZED: The PROFIdrive profile for PROFIBUS and PROFINET is now an international standard. IEC 61800-7 defines device profiles for electric variable speed drive systems and their mapping on existing communication systems by applying a generic drive interface. The PROFIdrive profile can be used on both PROFIBUS and PROFINET, with many common features making engineering and operations easier. The separation of application and communication makes it possible for device manufacturers and users to easily use PROFIdrive applications on either PROFIBUS or PROFINET and to freely select the optimal communication system for their needs.

EDD CERTIFICATION STARTS: In January 2008, PI accredited itm in Munich, Germany, as the first EDD test laboratory. At the same time the first EDD Certificate was issued. Accredited EDD test laboratories, among them ifak and itm, will offer the EDD accreditation service alongside existing PROFIBUS certification tests. PI has also commissioned ifak, also from Germany, to implement a new EDD import library, to ease the development of device descriptions by making it easier to adapt to device characteristics. The library will provide electronic device descriptions for PROFIBUS PA profile conformant blocks, which can be composed to a device EDD. For PI members, the new library will be available free of charge. itm or ifak. PI also supports FDT and is part of the EDDL Cooperative Team (ECT) with HART, FF, OPC, and now the FDT Group, too. A common solution uniting EDDL and FDT is being pursued by the ECT.

INTERNATIONAL MEETING INTRODUCES FREITAG: Twelve Regional PI Associations (RPAs) were represented at a special RPA Chairmen Meeting held on January 17, 2008, in Karlsruhe, during which Acting Chairman Mike Bryant introduced the new Deputy Chairman Jörg Freitag (right). Agreeing and further developing the worldwide PI Strategy was one of the main goals of this meeting. Bryant took his colleagues through a brand new strategic plan for the organization, explaining several new initiatives. Freitag welcomed attendees and spoke about the exciting challenges that lie ahead. “PROFINET will very soon reach the same level of acceptance worldwide that PROFIBUS has,” he said. “The worldwide PI organization is one of the reasons for our success and meetings like this demonstrate the talent and enthusiasm that is ultimately going to make PROFINET even more successful than PROFIBUS.”

NEWS FROM THE BLOG: PROFIBLOG continues to attract attention. Latest topics include a serious look at more of the myths mentioned in the Timoney paper (see Polly above). There's often some silliness to lighten the atmosphere (can you really judge a fieldbus by the number of books published about it?) and, frequently, educational items and helpful advice too. RSS can make the job of keeping up to date easier - see next item.
