Welkom bij PI Nederland! So says the web pages of the newly-renamed PI Netherlands, which have just gone live at www.profibus.nl. Fully integrated within the PI web site, the pages feature extensive Dutch translations of PI resources at www.profibus.com such as the technology pages and product catalog. A new logo (see right) has also been introduced. Forthcoming events on the ground include a national 'PROFIBUS, PROFINET and IO-Link Day' on November 18th, featuring Technology Corners supported by leading members. There will be 20 presentations including one by Xaver Schmidt of Siemens who will provide a 'look into the future'. More information here.
In industry a large number of 4-20mA transmitters are compatible with the HART protocol and in some cases these devices are connected to the control system via a PROFIBUS networked remote I/O stations.
A remote I/O can diagnose whether the 4-20mA HART signal is within its limits - i.e. locate a wire break - however it does not in itself allow any real connectivity to the device. In the absence of a HART multiplexer, these devices are only configurable using a handheld communicator or a HART modem. Unlike PROFIBUS PA instruments that can be viewed in multidrop mode, this necessitates connecting to each device separately in order to set the desired parameters. The result is that the user must go into the field to do a job that can otherwise be undertaken from the control room.
The problem can be resolved however if the HART bypass capability of the remote I/O station such as STAHL IS1 is utilized. This is a commonly unused capability of HART devices connected to remote I/O stations. Gateways such as Endress+Hauser's Fieldgate FXA720 in combination with Fieldcare from E+H facilitate such a process and can be connected to the internet allowing communication with the HART devices over PROFIBUS network from any location in the world.

With PROFIBUS, the use of manufacturer-specific description files means that users have to replace a process field device with an identical one. The recent introduction of PROFIBUS PA Device Profile 3.02 changes all this as a new field device can now automatically assume the device version of an older device without any interruption to the process. The replacement device thus presents itself to the control system as its predecessor, even though it may be 10 years more advanced.
This brings some valuable benefits. During a subsequent planned shutdown, the new functionality can be integrated by updating the description file. The same applies to the integration of an EDD or a DTM during a device replacement. It is also possible with Device Profile 3.02 for a new device to assume the functionality of several predecessor versions.
Device Profile 3.02 has recently undergone tests at BIS Prozesstechnik in Frankfurt, where one of the world's largest multi-vendor fieldbus test installations (see right) is installed. The laboratory is also a test center for EMC and actuator technology (SIL, CE, TA-Luft), a PI Competence Center (PICC) for PROFIBUS, and a Fieldbus Foundation Center of Excellence.
In the Profile 3.02 tests, two scenarios were considered: first, the replacement of an existing device while the process was running and, second, the display of status signals according to NE 107. Two field devices – a Samson actuator and an Endress+Hauser head transmitter – were tested in combination with five different control systems from Siemens, ABB, and Schneider. Three types of segment coupler were also included in the tests.
To start, a PA device assembly was configured and commissioned for each control system. Each was then replaced with a newer version. The cyclic transfer of measured values and the status of the measured value were monitored. The tests also included the mapping of specific diagnostic information onto four standardized categories according to NAMUR Recommendation 107. Different error scenarios were simulated. All tests were successfully passed.
Profile 3.02 can also handle faster uploading of parameters for optimizing transmission times. Different quantities of data must be transferred depending on the phase in the life cycle of a field device. Thus, a portion of the parameters must be adapted during commissioning, another portion during subsequent maintenance activities, and a large portion during device replacement. Depending on the functionality of the device, it is not unusual to deal with 300 parameters. The new PA Profile 3.02 optimizes the transfer by grouping parameters. This allows the transfer times to be reduced many times over (5- to 10-fold, depending on the data quantity). These functions are not yet available in devices so further testing will be carried out later.
PI is undertaking a worldwide survey about PROFINET. We want to know what you think about it. Are you using it yet? How do you rate its efficiency? It will take you no more than 5 minutes to answer a few key questions on-line here, and in that time you could help us improve the relevance of PROFINET to your needs. (link to come here).
The special capabilities needed by PROFINET to make it fully acceptable to the process industries are being specified now by PI Working Groups and nearing review. They should be released early in 2011. PROFINET supplements PROFIBUS in hazardous environments by providing a high-speed, high-bandwidth backbone for PROFIBUS PA (and other networks) while providing immediate connectivity for drives and discrete IO. The specialist process automation requirements being addressed are: Proxies, 'Configuration in Run' (CiR), Time Sync / Time Stamping and Scalable Redundancy. PI North America member GE is participating in the Working Groups to help develop these capabilities.
PI has published a 'PROFIBUS Guideline for Planning'. It's the third of a three volume 'Installation Guide'. The first two volumes - 'Cabling and Assembly Guideline' and 'Commissioning Guideline' - have been available for sometime. The volumes cover PROFIBUS DP and PROFIBUS PA. In addition to providing support for the plant topology definition, the guideline covers the selection of cable types and plug connectors, the planning of copper and optical transmission lines, tips for estimating bus cycle times and information regarding shielding and grounding. There's also a template for planning and documenting plants. A pdf is
available here for free download.
A new White Paper from HMS gives a quick overview of PROFINET and points out what needs to be taken into account for a successful migration from PROFIBUS to PROFINET. It shows the main differences between the two and points out their common ground. It also gives a basic overview of the key functions and features of PROFINET without getting lost in bits and bytes. The White Paper is available in English here.
As the fourth biggest passenger-car seller in China, Chery Automobile China, is enjoying great success. It is upgrading its transfer press line and increasing throughput by adopting state-of-the-art safety systems. PROFINET with integrated PROFIsafe is being used for automating the feeders between the individual press stages, based on Siemens SIMATIC safety products. PROFINET IRT is employed to enable virtual real-time communication within the system and to synchronize the feeders within one millisecond. CBE 20 communication processors with integrated ERTEC chips ensure that the SINAMICS converters respond equally quickly. PROFIsafe meets the strict European safety requirements of SIL 3 (Safety Integrity Level 3). The PROFINET bus architecture is open and can be enhanced at any time. No separate bus structures or cable systems are required for the safety-specific functions or for the drive synchronization. Thanks to the uniform bus structure of the system controller, drives and peripheral systems, Chery is able to reap considerable savings. The whole system runs on a single platform, resulting in significant cost reductions for engineering, commissioning, maintenance and ongoing production. It has helped Chery increase throughput by 15% compared with manual systems. SIEMENS

Attempts to establish Regional PI Association (RPA) in the key Middle East area have not so far proved fruitful ... but that’s all about to change! Paula Doyle from Ireland has recently taken up a new job in Dubai with Siemens and part of her mission is to set up an official RPA (Regional PI Association) as soon as possible. Paula is from Limerick in Ireland, where she gained her PhD. For the past four years she’s been in Scandinavia developing new control products for ABB. Her position with Siemens in Dubai is firmly centred on PROFIBUS and will allow her to focus her marketing skills on helping PI expand in the Middle East, a key area that deserves more support from the PI community. Her presence at the 23rd PI Meeting in Rome (see full report left) gave her the chance to meet current RPA Chairmen and to find out 'how they did it'. We’ll keep you informed of Paula’s progress.
Among the many presentations given on the PI booth was one about FDI technology. PI is actively working as part of the FDI Cooperation to help develop FDI, which will lead to a big reduction in the costs of maintaining plant assets. It enables both FDT- and EDDL-based host systems to manage field devices using a single engineering package, so it will make different engineering solutions for different devices obsolete
. It also provides a scalable alternative in applications ranging from simple configuration to the complex management of sophisticated field devices.
PROFINEWS is published by PI, a global community supporting technological excellence in industrial automation. It represents PROFIBUS, PROFINET and IO-Link and actively collaborates with other leading automation groups such as ECT, HART, FDI, FF, OPC and WCT.

The Indian PROFIBUS, PROFINET Association (IPA) now has 18 active members and is poised for aggressive growth. The list includes prominent end users such as Reliance Industries which is led by Mr B R Mehta. IPA participated in the Automation 2010 Fair in Mumbai in September with its own booth, where the PICC at UL Group showcased a multi-vendor PROFIBUS/PROFINET system. The fair gave a first opportunity for IPA to hold a conference to present PROFIBUS and PROFINET to
participants. Prominent customers from the automotive industries, process, power, OEM and system integrators attended. IPA recognized the presence of UL Group's PROFIBUS partners, namely Lothar Schröttel and Stefan Ruebesam of Profichip, and Juergen Bischhaus and Staffan Dahlströmof HMS, who shared their views on PI technology and the market opportunities in India. The conference featured multiple sessions from prominent speakers and was attended by about 140 delegates. The second edition of the IPA newsletter was introduced by Mr B R Mehta of Reliance. The IPA conference won an award for the 'best technology presentation' and UL Group won a 'best stall' award. IPA plans to do more Road Shows and intends to participate in more exhibitions.

To support the rapid worldwide dissemination of its unique point-to-point connection solution for smart actuators and sensors, the IO-Link consortium has created a new infrastructure. Accordingly, IO-Link is now part of Technical Committee (TC6) within PI and is also represented on the Advisory Board.
Working Groups (WGs) in the areas of technology, marketing, network integration, and profiles make up the infrastructure for further technical development and efficient dissemination of IO-Link technology. A new Steering Committee (SC) has been formed, to include representatives of all IO-Link interest groups (master manufacturers, device manufacturers, system providers, service providers, and chip manufacturers).
Perhaps the biggest change is the elimination of the membership entrance fee of EUR 10,000. Membership in a Regional PI Association and acknowledgement of the IO-Link System of Rules now provides access to the specifications, participation in WGs, and use of the "IO-Link" logo.
IO-Link enables quick and easy expansion or simplification of PROFIBUS and PROFINET networks. An IO-Link expansion module attaches directly to the network as a node, allowing up to four intelligent sensors to be connected. This cuts costs by up to 40% claims Balluff because one expander and 4 discrete sensor hubs can replace 5 discrete PROFIBUS modules. Further, up to 76 sensors per node are possible. BALLUFF
India ran a series of workshops in December for engineers from the cement and electronics industries. About 55 people attended. The event was a great success says Dileep from UL.
PI has abolished the certification fees for PROFINET products for PI member companies, now that the certification process has been fully developed. Certification nows covers the entire functionality of PROFINET, extending from IO devices with RT functionality and IRT functionality to IO controllers.
Terminales Portuarias S.L. (TEPSA) is an independent company in Spain that specializes in the reception, storage and forwarding of bulk liquid products such as chemicals, petroleum products and biofuels. It currently operates from four Spanish ports: Barcelona, Bilbao, Tarragona and Valencia.
During a recent refurbishment, TEPSA decided to replace a maximum level alarm system based on float switches with a SIL 2 compliant system. The new system had to be testable prior to each load and should use existing wiring. Endress+Hauser Spain acted as main automation contractor and were responsible for engineering, project management, commissioning, training, post-project process audit and 3rd party installation supervision.
350 tanks in hazardous areas have been equipped (across the four ports) with Liquiphant level switches connected to Nivotester switch amplifiers. Turk BL20 PROFIBUS RIOs are used for local alarming, connected to six SFC173 PROFIBUS Field Controllers via PROFIBUS DP. The Field Controllers themselves communicate with a P View SCADA system via an OPC server and Ethernet backbone. A central workstation with P View Client/Web Server monitoring is used to acquire and visualize incoming data.
The ControlCare system provides a complete tank monitoring solution with alarming and visualization. The alarms are indicated locally by P View web clients and annunciated remotely via a Motorola radio messaging system (recorded voice), also triggered by ControlCare. The P View Multimedia module, which sends SMSs, calls or e-mails, was used to configure individual voice messages for each level switch.
For TEPSA, the new system fulfills all technical requirements. In Endress+Hauser they have a solution provider who has taken responsibility for all phases of the project and who provides expertise and maintenance when the tank farm is operating. The system is open and easily expandable too, e.g. to a full level monitoring or inventory management system.

A comprehensive offer of products and services is now available from a wide range of providers to aid with the design and development of PROFINET devices. As well as sophisticated SDKs, firmware based on Standard Ethernet interface, PROFINET ASICs, and ready-to-install modules can now be easily purchased to support fast and effective deployment of PROFINET devices. A brochure entitled “The Easy Way to PROFINET Technology" has been published and is now available for download HERE. This includes a full overview of all providers. With the release of the new TPS1 (TIGER ASIC) by Phoenix Contact, yet another PROFINET chip is now available to assist device implementers. TIGER has been designed especially for compact devices (e.g. compact IO modules or drives).
EtherCAT and Powerlink, which focus mainly on drive technology, were estimated to have market shares of 4% and 11% respectively (see graphic).
IMS Research forecasts PROFINET to grow the most between 2008 and 2013, with +8.7% (CAGR). It predicts EtherNet/IP will grow more slowly (by +7.1%) and Modbus TCP/IP will decline (by about -0.4%). IMS RESEARCH
In a new market study called “The World Market for Industrial Ethernet – 2009 Edition”, IMS Research in UK estimates that with a market share of 28% PROFINET is amongst the top most-used Industrial Ethernets worldwide. The study particularly notes that PROFINET offers an Industrial Ethernet solution for a comprehensive range of applications, including high-speed motion control. PROFINET, EtherNet/IP and Modbus TCP/IP fill the top slots, accounting for 80% of the total market.http://www.imsresearch.com/index.php
Welcome to another packed issue of PROFINEWS! With 2010 nearly over it is timely to look at the progress being made by PROFIBUS and PROFINET. We learned earlier this year that in 2009 both technologies withstood the ravages of the economic downturn well, and I believe that 2010 will show outstanding progress. We will have to wait for the official figures for confirmation but what I am sure of is that PROFIBUS and PROFINET are helping manufacturers everywhere become more competitive and more productive, and thereby they are contributing a lot to the collective effort to climb out of recession. For 2011 I can tell you that PI is looking to expand its horizons to further boost PROFINET in particular. We will be attending several fairs that thus far have remained outside our main area of interest. The best example I can mention is 'Embedded World' in Nuremberg in March, which our technology supporters in particular are keen to attend. The aim there will be to show the extensive range of chip, board and other resources that are available to help device vendors integrate PROFINET into products and systems. We will also demonstrate how IO-Link is an ideal partner for PROFINET in this scenario. But that does not mean we are ignoring our mainstream fairs. We will be at SPS/IPC/Drives as usual in November in Nuremberg to promote our full technology solutions range at Europe's most prestigious automation event. I will be there too and I'll be pleased to welcome you in person on the booth (below). See you in Nuremberg?

It supports all commonly used Gigabit and Fast Ethernet data transfer standards, standard IT protocols as well as PROFINET.
The modular concept allows expansion to 28 ports. Twisted pair and fiber options are available.
The switch includes diagnostic and configuration functions Important parameters can be read and set at the device using an operator console. S
upport for the energy management of automation systems via the PROFIenergy profile is incorporated
.
Of those 31.4 million PROFIBUS devices, 5.4 million are now used in process automation so it's clear that PROFIBUS has assumed the dominant fieldbus role. The latest PA Profile V3.02 is expected to accelerate this since it contains a set of important asset management features specifically requested by end users.
In the Functional Safety market, PROFIsafe continues to lead as well. The 220,000 purchased PROFIsafe devices in 2009 equals the number purchased the previous year. The installed base of PROFIsafe now exceeds 850,000 devices.
NB: PROFINET market statistics are collected by an independent and fully neutral third party. Only end devices are included in the count; infrastructure devices are excluded.
Paula to set up Dubai office
Attempts to establish Regional PI Association (RPA) in the key Middle East area have not so far proved fruitful but that’s all about to change. Paula Doyle has recently joined Siemens in Dubai and is planning to set up a formal RPA there shortly. Paula is from Limerick in Ireland, where she gained a PhD. For the past four years she’s been in Scandinavia developing new control products for ABB. Her move to Dubai means she can now focus her marketing skills on helping PI expand in the Middle East. She told PROFINEWS that legal requirements in Dubai mean that some kind of PI Competence Centre (PICC) will have to be established first. Her attendance at the 23rd PI Meeting gave her the chance to meet many of the other RPA Chairmen and to see how they did it. We’ll keep you informed of Paula’s progress.
PI and its members were strongly represented at the recent Hannover Fair in April, with a new booth design reflecting the latest corporate design standards. Multi-vendor demonstrations, a host of new products and many educational seminars gave visitors a full insight into PI activities. Major topics included PROFINET, PROFIsafe, PROFIdrive, and of course the new PROFIenergy profile which promises to cut energy consumption dramatically.
Automation users try when they can to minimize energy consumption, responding to pressures to cut costs and comply with increasingly stringent ‘green’ obligations.
Methods range from switching off equipment manually to installing semi-automated shut-down systems. Both are usually crude, expensive and hard to manage. To maximize energy savings a single, standardized, approach supported by vendors and users industry-wide is required – hence the PROFIenergy Profile.
The idea for PROFIenergy came from AIDA, the Association of German Automotive Manufacturers, who asked PI to develop a way of intelligently managing the energy consumed by power-hungry equipment such as robot cells. If these Energy Consuming Units (ECUs) could be switched on and off in an open, consistent and managed way, they argued, substantial cost savings could be achieved.
The PROFIenergy Profile enables control devices (e.g. PLCs) to send signals such as Begin Pause and End Pause over PROFINET to each ECU, in accordance with production circumstances such as lunch breaks, holidays, random line stoppages and even maximum load conditions. On receipt of the PROFIenergy commands, software ‘agents’ in the ECU firmware initiate ‘sleep’ modes that are pre-defined by the equipment vendor.
PROFIenergy can operate either alongside existing automation processes on a single controller platform, or a separate, dedicated, energy management controller can be used. PROFIenergy is applicable to single devices such as actuators and remote IO, as well as sub-systems such as robot cells and paint lines.
PROFIenergy is thus an ‘enabling technology’ that allows intelligent energy management strategies to be deployed over existing PROFINET networks. Vendors support PROFIenergy by implementing the required functions in their devices or sub-systems, thereby making PROFIenergy available ‘on tap’. Actual energy savings depend on how end users choose to adapt PROFIenergy to their automation networks.
Early estimates by one automotive manufacturer suggest that savings of up to €60,000 per annum could be achieved for a robot cell through the use of PROFIenergy.

FDI workshop
At the Hannover Fair on April 20, 2010, experts discussed the latest development of FDI technology. The primary benefit of FDI is that end users with either an FDT- or an EDDL-based host will have a single source solution for managing field devices. Users will no longer need to manage disparate device descriptions, which will reduce the costs associated with maintaining assets in the field.
The FDI project will also provide a very scalable solution that users can deploy in applications ranging from simple configuration to complex management of the most sophisticated field device. This makes different solutions for different devices obsolete. An example of this is that FDI device packages for applications such as valve diagnostics will provide the same functionality regardless of the host system.
The discussion was moderated by Dr. Thomas Tauchnitz, Sanofi Aventis. Participants were Kimikazu Takahashi (Yokogawa), Hartmut Wallraff (Invensys), Daniel Huber (ABB), Hans-Georg Kumpfmüller (Siemens) and Dr. Raimund Sommer (Endress+Hauser).
