Dear Readers,2005 is the Chinese year of the rooster. This yearand sign are associated with change, new tech-nologies, and innovation – and we can be morethan satisfied with our growth and developmentthis year. We have expanded our leading marketposition and have continued our rapid develop-ment in the Asia-Pacific region. In Asia, and espe-cially in China, a continuing economic boom isexpected – reason enough to put Asia at thecenter of focus in this issue of Process News. In14 pages, we not only present our strategies forthis region, and for the Chinese market especially,but also show how our solutions can contributeto the economic success of our customers in Asia.

One of the major reasons for this success arecertainly our efforts to always be close to thecustomer and to the market. That applies equallyto technological equipment and regional marketpresence. From the very start, for instance, wehave ensured that our now 2,800 employees atSiemens Automation and Drives in China are qual-ified and able to offer our customers in thisimportant market local expertise.

Growth, innovation, and reliability are alsoreflected in the thematic emphasis of the articleshere, in which ideas from the five elements ofChinese philosophy have been borrowed: wood,fire, earth, water, and metal.

But we don’t want to give short shrift to oursuccesses in Europe and Germany either. We wererecently able to complete an extensive project atMerck, for example, in which we implemented astandardized solution with Profibus.

I hope this issue gives you a few valuableideas, and above all, some insight into our Asianbusiness.

Best regards,

Nestlé equipped the production facilities at theirWeiding site with a new process control systemthat is modular and scalable in structure, and thatmeets all the requirements of modern productionautomation: Simatic PCS 7

can support such vast and diverse produc-tion facilities in the parks is a very chal-lenging task in itself – power supply, pro-cess heat and cold, process water, logisticsfacilities, wastewater treatment, and otherutilities projects accompany the industrialinvestment in the parks.

Teaming up for success

The projects in these parks also hold bigpotential for automation technology sup-pliers. International companies view thesesites as important nodes in their global pro-duction networks and, consequently,expect them to live up to their global stan-dards. Being internationally competitiveis an important aspect in the productiondesign.

In the utilities sector, reliability and per-formance are crucial. In parks of this size,a failure in the power supply, for example,

will quickly result in several million dol-lars in economic damage. Chemical compa-nies and park operators are therefore look-ing for experienced and capable partnerswho can offer reliable, open, and globallyaccepted solutions.

Global knowledge and local expertise

Siemens has been able to demonstrate itsproject capabilities in several of theseparks, especially in the area of power sup-ply and generation and middle- and low-voltage switchgear. From high-perform-ance, high-efficiency turbo sets for steamturbines to standardized, modular low-voltage equipment to reduce maintenanceand stocking costs, Siemens offers the com-plete range of systems and solutions forpower generation, transmission, and dis-tribution. And with more than 60 years ofexperience in power supply projects allover the world, Siemens also has the proj-ect expertise to handle even the most com-plex projects.

With a strong product and solution rangebased on Totally Integrated Automation,Siemens is also one of the main interna-tional automation providers and has a longlist of successful projects in the chemicaland pharmaceutical industry. As a strategicpartner to several international chemicalcompanies, Siemens has proven not only itscommitment to the chemical industry, butalso the versatility and quality of its prod-ucts, systems, and solutions. By offering theright products and systems, and by using

Mega projects in China’s chemical industry

Bigger Is BetterWith a potential market of one billion people and an annual growthrate of 9 percent, China is one of the most important and excitingnations in the world for industrial investment and development. Thechemical industry in particular is currently making huge investmentsto expand local production capacity for base and specialty chemicals.At present, more than 50 large chemical industrial parks are beingdeveloped in China, offering vast opportunities for system andsolution providers such as Siemens. With mature products andsolutions and an efficient customer support network, Siemens offersan optimal project approach for those mega projects.

G eographically, 50 percent of theseparks are located within a radius ofabout 600 kilometers around Shang-

hai; they offer a direct connection to inter-national transportation systems either bybeing directly on the coast or situated alongrivers. Other centers of activity are in thesouthern Guangdong province and in ornear the Beijing area. Each chemical indus-trial park is between 10 and 100 square kilo-meters in size, dwarfing, for example, BASFLudwigshafen, previously one of the largestchemical complexes in the world, which hasan area of approximately 7 square kilome-ters.

In the so-called first wave of investment,from 1996 to 2005, national and interna-tional companies have invested between0.5 and 8 billion euros at each park. In thesecond wave, which is currently in the plan-ning stage and is scheduled to take until2011, experts expect that investment levelswill reach, or in some cases exceed, those ofthe first wave.

All the big players present

The list of investors and companies presenton these sites reads like a who’s who of theglobal chemical and pharmaceutical indus-try: Air-Liquide, Air Products, AstraZeneca,BASF, Bayer, BP, Cargill, DyStar, Degussa,DuPont, DowChemicals, ICI, Linde, Mit-subishi, Novartis, Sinopec, and Wacker, toname just a few. Less internationally knownyet still important local companies are alsoparticipating. Setting up infrastructure that

the technical expertise and experience ofthe Siemens staff in China and globally,Siemens is able to provide sustainable sup-port to achieve its customers’ goals. Nearlyall services are available close to the projectsites, with guaranteed and quick availabil-ity of spare parts.

Two examples: Shanghai and Nanjing

One of the parks where Siemens has beenable to demonstrate its capabilities is theShanghai Chemical Industrial Park (SCIP),which occupies an area of about 30 squarekilometers in Caojing. The park began its

business activities in 1998, in petrochemi-cals and chemicals, and is expected toreceive an estimated total investment ofapproximately 15 billion euros by 2012.

During the first wave of investment,Siemens supplied motor, drive, and con-trol technology for a PET products facilityfor Alsion, and in a large infrastructure,PIC, and PC project for Bayer, Siemens wasresponsible for designing and implement-ing the complete middle voltage distribu-tion system and low-voltage components.Siemens also won a single-source contractfor pressure transmitters, and supplied

drives, PLC systems, fire alarm systems, andtelecom systems as well as systems for theprocess analytics.

Another very large chemical industrypark is situated near Nanjing, an importantlocation for China’s chemical industry. TheNanjing Chemical Industry Park, positionedalong the deepwater line of the YangtzeRiver, was established in 2001 and has sincebecome an important petroleum and chem-ical base in the country. The total area of thepark is about 100 square kilometers. Here,Siemens has been especially successfulwith BASF, which is setting up an integratedpetrochemical site at Nanjing. Siemenssupplied the entire power distribution sys-tem, as well as control technology, motorand drive technology, compressors, andsystems for the process analytics.

Well prepared for the second wave

After the first wave of investment, Siemensis now ready for the next big projects. Witha long list of successful projects and satis-fied clients from the first wave, along withthe excellent reputation of its systems andsolutions, prospects are good that Siemenswill be even more successful in the secondwave of investment. ■

C hina accounts for about one-fifth ofthe world’s population, and its econ-omy is growing annually by about

nine percent, so it is no surprise that thecountry has an enormous energy demand.Power-generation capacity will continue togrow dramatically until 2010. AlthoughChina strongly promotes renewable andalternative energy sources, fossil fuels(especially coal) still account for the lion’sshare of the country’s energy. The disad-

Simatic technology and process expertise in desulfurization plant

Scrubbed CleanIn a breathtakingly short time, China has become one of themajor industrial nations, playing a key role in global markets.But this rapid development has had its drawbacks. Above all,increasing environmental pollution has often made the newsin recent years. The Chinese government, with cooperationfrom private enterprises, has now taken initial measures torestrict the emission of pollutants.

The Siemens Industrial Automation Ltd. (SIAS),headquartered in Shanghai, was founded in1995 and supports key Chinese industries in theautomation of their processes. The focus waspreviously on industries such as chemicals,petrochemicals, pharmaceuticals, semiconduc-tors, and glass. However, projects in the field ofenvironmental technology are becoming moreand more important. Here, SIAS acts as an expe-

rienced systems integrator and also offers acomplete range of services in the field ofprocess control. The company is able to imple-ment turnkey automation projects – from con-sulting through project management to installa-tion of all the necessary hardware components.

A spare parts warehouse with a maximum re-sponse time of 24 hours guarantees the avail-ability of Siemens systems throughout easternand southern China. Added to this are a highlyqualified technical support staff and a certifiedtraining center supplemented by a software de-velopment office that localizes technical docu-mentation for the Chinese market.

vantage: the burning of coal, with its highsulfur content, is one of the main causes ofenvironmental problems such as smog andacid rain.

A growing market

This is one of the reasons why Beijingintends for China to become one of theleading countries in matters of environ-mental protection. China has therefore ini-tiated a cooperation program with the EU inthe field of power and environment, amongother things. The aim of the program, whichis supported by an investment of 43 millioneuros, is the more effective exploitation ofavailable energy resources, while drasti-cally reducing pollutant emissions.

China’s growing environmental con-sciousness also has far-reaching economicconsequences. The ECOTEC Institute, forinstance, forecasts that the Chinese marketfor environmental technologies will growto about 17 billion euros by 2010.

This will make the People’s Republic ofChina one of the most important markets inAsia for environmental technologies. Ana-lysts predict that a considerable amount ofinvestment will be devoted to installingplants for exhaust gas purification, desul-furization, and denoxification.

600 megawatt with minimum sulfur emission

One example of China’s growing environ-mental consciousness is the Jiangsu Xutangcoal power station in the eastern Chineseprovince of Jiangsu Sheng, to the north ofShanghai. In the course of a nine-monthproject, the 2 x 300-megawatt power stationwas equipped with a flue gas desulfuriza-tion plant using the so-called wet process,in which limestone reacts with sulfur diox-ide to form plaster.

Because the process steps must be con-tinually regulated and controlled, thedemands on the automation system of thedesulfurization plant are high. A specialchallenge in this project was the strongelectromagnetic fields typical of a power-station environment. The entire systemalso had to be designed redundantly in crit-ical areas and equipped with various self-diagnostic functions to guarantee maxi-mum operational reliability.

The contract for the design and installa-tion of the automation system was awardedto Siemens and was implemented bySiemens Industrial Automation Ltd. (SIAS).The control system is made up of severalsingle-function blocks and subsystems that

control individual process steps and com-municate with the main system. The heartof the automation solution is the SimaticPCS 7 process control system with threehighly available AS 417H automation sys-tems, two operator systems, and one engi-neering system. The solution also includesthe medium-voltage systems, as well as asystem for monitoring emissions. In addi-tion, a communication link was establishedbetween the PCS7 system in the flue gasdesulfurization plant and the control sys-tem in the power station.

Successful installation

The project was implemented with nomajor hitches, and PCS7 is already showingits value in reliable ongoing operation. Thepower station owners are very pleased withthe new flue gas desulfurization plant andthe automation solution. Siemens and SIAShave obtained an impressive referenceaccount in this important future market inChina. ■

From flue gas to gypsum

The so-called wet flue gas (WFG) desulfurization process is one of themost effective methods of exhaust gas desulfurization and cancapture 95 percent of the sulfur dioxide contained in the flue gas.

In this method, the flue gases are sprayed with a mixture of waterand limestone in a vertical scrubber tower. The sulfur dioxidedissolves in the limestone slurry first, and then reacts with thelimestone to form calcium sulfite and carbon dioxide. The calcium

sulfite-charged washing suspension is collected at the bottom of thescrubber tower and enriched with oxygen by blowing air into thesolution so that the sulfite is oxidized to sulfate, resulting in gypsumas the end product of the process. WFG gypsum has a high level ofpurity, and after the water is separated, the dry gypsum can be soldas a base for building materials.

Mr. Herweck, in the past five years,Siemens Automation and Drives in Chinahas achieved double-digit growth. Isn’t that a bit much to be sustained over thelonger term?Peter Herweck: Only if you do not have asolid base for your business. We have morethan 2,600 employees, seven operatingcompanies, and 44 sub-offices. In fiscal2005, we will further expand our sales andservice network to 60 offices. Moreover, wehave a strong local presence and localexpertise, which will enable us to grow andeventually change with the market. We arealready a clear market leader in theautomation and drives market.

So you feel you are also well prepared tohandle future challenges?Peter Herweck: We definitely are – andthere are great opportunities ahead of us.The total Chinese DCS market alone isexpected to grow to as much as one billioneuros by 2008, with an annual growth rateof 15 percent. We benefit from this growthby developing strategic business allianceswith domestic systems integrators. Althoughthe Chinese market is extremely compet-itive, these companies are also continu-ously on the lookout for the latest tech-nologies. Many of the manufacturing facil-ities in China are designed and engineeredto meet not only the country’s domesticdemands, but also global demands. Pro-duction transparency is an important factorin achieving global competitiveness. WithTotally Integrated Automation and SimaticPCS 7, we can offer an excellent automationplatform for this.

So local partners are an important gatewayto the Chinese market?Peter Herweck: Definitely. The two othergateways are global strategic partnershipswith the big market players in the process-ing industry, and continuing to expand ourown expertise. We have been very success-ful with this approach, which has alreadypaid off in the last years in 380 SimaticPCS 7 projects in China completed by SIAS,Siemens Industrial Automation Ltd. Shang-

You mentioned expanding Siemens’ ownexpertise. Does that also include after-salesservice?Peter Herweck: For Siemens, service andsupport have always been an important

part of our business. Despite the geo-graphical challenge and our confidencein the quality of our products, we main-tain a nationwide hotline network toprovide our customers with a fullrange of services. Our service engi-neers provide feedback within twohours. We have also set up seventraining centers – in Beijing, Shang-hai, Guangzhou, Wuhan, Chong-qing, Shenyang, and Harbin – totransfer the latest automation tech-

nology and product expertise to cus-tomers and partners in China, and we

launched a Web site dedicated to theChinese market back in 2000. It has

become one of the most popular portalsin China’s industrial circle.

What about the near future? Currently,there are major projects under way inpreparation for the Olympic Games inBeijing in 2008.Peter Herweck: Of course, as a companythat has become deeply rooted in Chinesesociety, we are very proud that we can makea contribution to this important event.As we demonstrated at the 2004 AthensOlympics, we are able to offer excellentsolutions for building security, and lightingsystems, as well as infrastructure and

transportation projects. Beijing wantsthese Olympics to be the best and the“greenest” Games ever, and has conse-quently launched programs to modernizeits energy and water management sys-tems. Siemens has already built more than200 water and wastewater treatmentplants in China, therefore we have ampleexperience in this field. We will also sup-port the Beijing municipal government inits modernization program for districtheating.

And on a more economic note – where doyou see Siemens Automation and Drives inthe Chinese market, say, five years fromnow?Peter Herweck: We want to become num-ber one or at least number two in all ourbusiness fields by providing the best prod-ucts, systems, solutions, and services to ourcustomers. The quality of our products andsystems is world renowned, and we havealso accumulated abundant solution andengineering expertise in diverse projectsaround the globe. I am confident that ourChinese customers will view us as a reliableand valuable business partner in manyareas as well.

Shandong Lunan CementIn order to maintain its leading position in the Chinese ce-

ment market and to improve the reliability of its produc-

tion, Shandong Lunan Cement has chosen to equip a pro-

duction line with the Simatic PCS 7–based Cemat process

control system. Since production start-up, Cemat has

proven to be stable, reliable, and easy to operate and

maintain. The system, which was designed to meet the

specific requirements of cement production, exceeds the

performance of the previously installed system in every

respect, making the new production line one of the best-

performing facilities of the company.

Tianji Coal ChemicalTianji Coal Chemical Industry Group, based in Lucheng in the province of

Shanxi, operates China’s first high-chroma-complex fertilizer facility to use

coal as a raw material. In September 2001, Tianji decided to set up a new

project for the production of nitric acid. For the automation of the plant,

Tianji chose a fully redundant Simatic PCS 7 process control system. Tianji

Coal was extremely satisfied with the new system’s performance and also

chose Simatic PCS 7 to replace the process control system in its older fertil-

izer production plant. That system went live in January 2005 and enor-

mously improved the automation level. After these two successful projects,

prospects are good that Simatic PCS 7 will also be applied in the Tianji Sino-

Chem Gaoping chemical plant that is soon to be built.

Within the scope of this project, as partof the expansion of Workshop 605, SimaticPCS 7 V6.0 and Simatic Batch V6.0 werecombined for the first time. The PCS7 sys-tem comprises around 400 I/O points andis networked with the plant’s productionscheduling. The distributed devices in theprocess are connected to the system viaProfibus DP, considerably reducing thenumber of fieldbus systems and facilitatingmaintenance.

Flexible recipes

Batch automation was implemented withSimatic Batch V6.0. Thanks to the flexiblebatch control, various cephradine products

can now be produced on the same line inaccordance with GMP. Equipment andresources can be used more effectively andproduction quality ensured. Moreover,recipes can be modified in the productionprocess, enabling rapid response to chang-ing market requirements.

Further integration planned

Wastewater treatment plant automation with Simatic PCS 7 northeast of Shanghai

Technology for a CleanEnvironmentSimatic PCS 7 has been used successfully in numerous wastewater treatmentplants for many years. Rugged technology, a guaranteed supply of spare parts,and flexible expandability are important benefits of the system. Recently,another project has been added to Siemens’ reference list: in the Songjiangdistrict northeast of Shanghai, a new wastewater treatment plant has beenautomated with Simatic PCS 7 and Sinaut.

13FOCUS

The wastewater treatment plant in theSongjiang district is part of one of themost important environmental proj-

ects in Shanghai. The new plant, sponsoredby the Shanghai municipality, features aneffective biological treatment process. Inaddition to purifying the wastewater gener-ated by the 320,000 inhabitants of the Song-jiang district, the aim of the plant is to helpimprove the water quality in the upper reachesof the Huangpu river, and also to increasethe processing capacity for industrial sewage.The daily treatment capacity during the firstphase of the project will be 70,000 tons.

Many arguments in favor of Simatic

Thanks to the outstanding price/perform-ance ratio offered by the proposed solution

and the ultramodern Simatic technology,Siemens Industrial Automation Ltd. Shang-hai (SIAS) was able to secure the order forthe plant’s automation technology. The reli-ability and stability of Simatic PCS 7 wereconvincing factors. Also playing a criticalrole in the decision to award the contractto SIAS was the fact that Simatic PCS 7enables all the control and automationsystem functions to be integrated on oneplatform.

All processes are controlled by the SimaticPCS 7 process control system. In phase 1 ofthe Songjiang wastewater treatment proj-ect, SIAS was also responsible for supplyingthe process instruments, providing thecabling between control room, processequipment, controllers, and decentralized

pumps, as well as supplying and installingthe access protection systems and a large-screen monitor. SIAS also supplied the tele-phone and radio systems for the treatmentplant and pumping stations.

In total, three PCS 7 automation systemscontrol the processes in the wastewatertreatment plant and are networked with theoperator stations via optical IndustrialEthernet. The distributed devices are con-nected to the control system with ProfibusDP. The treatment plant also has an exter-nal pump station, which is controlled byradio via the Sinaut telecontrol system, andwhich is also integrated with Simatic PCS 7.

Proven solution

Simatic PCS7 and Sinaut have proven them-selves in numerous wastewater treatmentprojects all over the world, and have alsoshown that they are well suited to the spe-cific needs of the new Songjiang districttreatment plant. Thanks to the great expert-ise of the SIAS team, no problems wereencountered during the commissioning ofthe plant, and one more project was addedto Siemens’ list of successful PCS 7 refer-ences in wastewater treatment. ■

Benxi I&S Group is the fifth largest steelproducer in China

For several years now, the Chinese steel industryhas been booming. Annual growth rates of 20 per-cent and higher are spectacular evidence of this.This growth is set to continue in the coming years –and with it the need for efficient and modernplants for steel production and processing. With itsadvanced, rugged, and redundant solutions forprocess automation, Siemens helps the Chinesesteel industry prepare to face future productionchallenges, as a few projects impressively demon-strate.

Blast furnace automation at Shaoguan I&S Co.

The steel complex at Guangdong Shaoguan I&S Co.is one of the largest in China. For some time now, a 2,600-cubic-meter blast furnace has been in op-eration at the facility. The plant features state-of-the-art automation technology realized by Shen-zhen Yuzhan Automation Technology. This was thefirst time that a Simatic PCS7 process control sys-tem had been used in a blast furnace of this size –

an important milestone for the application of PCS7in the steel industry.

All processes are completely controlled with PCS7,which means that the project was implementedwith relatively low engineering expenditure. Thefast and reliable data exchange ensures smooth op-eration, while the open interfaces allow the opera-tor to flexibly expand and modernize the system.

Sinter plant at the Benxi I&S Group

PCS7 is also proving to be a success at China’s fifthlargest steel producer, Benxi I&S Group. Since July2004, a 360-square-meter sinter plant has beenequipped with a redundant PCS7 system that isworking to the total satisfaction of the operator. Par-ticularly convincing is the open and versatile archi-tecture of the system, which enables the life-cyclecosts to be considerably reduced. In fact, the compa-ny’s owners were so impressed, that the first follow-up order has already been placed – for the automa-tion of five 70-square-meter sinter plants with PCS7.

a capacity for integration are vital. This iswhere Totally Integrated Automation comesin: open interfaces and uniform standardsmake a major contribution to the integra-tion of existing and additional systems. Wehave already completed about 30 projectswith Simatic technology or Siemens drivetechnology, including six larger SimaticPCS 7 projects, and TIA has also paid offfor us. We save on engineering time andcosts – advantages that also benefit our cus-tomers.

So, all in all, you are satisfied?

Sherry Lv: We still have a few requests tomake of Siemens and its products, ofcourse. However, I have to say that we arevery satisfied indeed. In the years to come,we wish to expand further, also outsideChina and into other industries. The open-ness and versatility of TIA can be put toexcellent use here, and Siemens, as a globalpartner, will also be able to provide us withforeign support. At the same time, I’m surethat the market environment will alsobecome more difficult. Pricing pressureand increasingly rigorous competition willdemand better and better services from us.

I expect that Siemens will continue to sup-port us here as it has in the past. Both com-panies must work even more closelytogether, as it is my opinion that this part-nership will lead to an almost unlimitednumber of new opportunities.

Ms. Lv, thank you for speaking with us.

FOCUS

T he sinter plant of the Shougang Min-ing Company was established in1990, and six sinter machines were

gradually put into operation in the first andsecond quarters of 1992. The plant wasoriginally controlled by a Simatic S5 con-troller. Load cells from local manufacturerswere used as the weighing system, with 42bulk scales.

However, the weighing technology even-tually began causing problems. The loadcells’ fault tolerance did not always meetthe requirements, so the weighing resultswere frequently unstable and the measur-ing accuracy did not live up to expectations.

The Shougang Mining Company approachedthe supplier of the weighing system, Bei-jing Yajielong Measurement & Engineer-ing Co. Ltd., to design a new concept for thecontrol and weighing tasks. Beijing Yajie-long was responsible for the design anddelivery of all the equipment.

Convincing results

After extensive comparisons, the projectteam chose a solution based on Siwarex U.Positive experience with the technologywas reported from other plants, as theweighing system is often used in sinter fac-tories. Another positive feature of the new

solution was that it could be implementedwith relatively little installation effort. Theweighing systems are linked by SimaticET 200M I/O systems and Profibus to theSimatic S7-400 controller, which consider-ably reduces wiring work. At the same time,the new system operates much more stablyand accurately than the previous solution.The accuracy of the weighing processincreased drastically after the new systemwas installed, and thanks to the compo-nents’ high fault tolerance, problems withelectromagnetic fields are now a thing ofthe past.

Significant advantages

Another advantage of the solution is thatthe weighing system can be calibratedlocally on site, via a graphic interface in thecontrol system. The weighing data them-selves can easily be logged and managed. Inaddition, the modules can be easily andquickly changed in the event of a fault, anda fast solution to the problem is guaran-teed, preventing long downtimes.

Guo Changjun, managing director ofBeijing Yajielong Measurement & Engi-neering Co. Ltd., sees this as an importantreason for the operational reliability of thenew system, and is convinced that this tech-nology, which has already proven itself insinter factories, will soon find its way intoother branches of the steel industry. ■

Siwarex U weighing system in sinter plant

Accuracy SellsStrong electromagnetic fields, harsh ambient conditions, andcontinuous operation – these demands were too great for the existingweighing technology in a sinter plant owned by the Shougang MiningCompany. The company was looking for a robust, reliable, and accuratealternative. The solution: Siwarex U weighing systems, which havealready proven themselves in numerous similar plants.

In the coal and ash silos of the Diandongpower plant, the installed level-monitoringtechnology did not work reliably enough,especially during loading times, whenlarge amounts of dust were generated. TheChengdu power design institute, which wasresponsible for developing a new monitor-ing solution, opted for Sitrans LR 400 radardevices. Sitrans LR 400 has been success-fully installed in applications in the cementindustry, and is known to work reliablyeven in extremely dust-laden environ-ments. The devices lived up to their repu-tation, and the power plant will now equipall its silos with Sitrans LR 400 – a total of66 devices.

In the Jia Xing power plant, four gener-ation units of 600 megawatts each havebeen equipped with a total of 1,400 SitransP pressure transmitters during the last twoyears. The Sitrans transmitters offered anexcellent price/performance ratio and wereable to beat strong competition during thebidding phase, due in large part to the easeof installation and commissioning.

Application expertise: Difficult monitoring task in fiber productionIn a production facility for synthetic fibers in southern China, the plant operator was look-ing for a monitoring solution that would be able to cope with the demanding ambientconditions while requiring little maintenance.

Previously, the client had used differential pressure monitoring on the mixture ofacetic acid, water, and slag, but the slurry’s tarlike high viscosity, strong steam develop-ment, and low pressures of less than one bar were putting considerable stress on themonitoring devices. Maintenance requirements were high, and the lifetime of the deviceswas very limited. Moreover, the slurry tank was equipped with several heating coils thatposed an additional challenge to the Siemens application engineers who took on the taskof developing a more suitable level-monitoring solution.

Through a detailed analysis of the monitoring conditions, the engineers determinedthe right position for the monitoring devices and chose Sitrans LR 400 radar transmitters,which have proven to be reliable in tar level monitoring. The results were excellent. Al-though two horizontal bars and a heating coil obstruct the monitoring, the Sitrans devicehas a monitoring range of up to 7.7 meters – very high for such difficult conditions – andis working reliably.

The client was very impressed with the test results, and Sitrans LR 400 and theSiemens engineers were once more able to demonstrate that the right combination oftechnology and expertise will help solve even very challenging problems.

A single-source provider

Siemens is able to equip the entire plant asa single-source supplier and therefore con-siderably reduce the duration of the proj-ect. In addition, Siemens products and sys-tems are backed by a high level of develop-ment competence and broad technical sup-port. Together, these aspects result in highinvestment security – a major considera-tion for a modern, future-oriented com-pany nowadays, and another importantfactor in the decision to place the orderwith Siemens.

Toho Tenax has long years of experiencewith Siemens products and uses the Tele-perm M process control system in its exist-ing plants. Based on this positive experi-ence, Toho Tenax decided to implementSiemens technology in the new productionline as well. Simatic PCS 7 and Profibusoffer integrated intelligence right down to

Thanks to Totally Inte-grated Automation, everything from fielddevices to the process control system isguaranteed to fit together perfectly, andthe entire workflow, from incominggoods through production to delivery, islinked in a single, integrated system.

Experience pays off

With its interdisciplinary competence inboth plant design and automation technol-ogy, Siemens offers bundled expertise thatis unique in the industry, and that canreduce project lead times. Many projectsteps can run in parallel because therequired expertise is in the same hands.For example, the time required for themechanical installation took two weeks lessthan originally scheduled.

Similar results are expected for the com-missioning phase. Here, those responsiblefor the project estimate that it will take fourweeks less, solely due to the fact that the

consistent use of Profibus PA creates con-siderable synergies. Another aspect of theproject is also particularly interesting: TohoTenax will be working on the further opti-mization of its production process duringthe detail engineering and building of theplant. This simultaneous engineering isno problem for Siemens. The expectedmodifications will be integrated directlyinto the current project steps.

Conditions are therefore ideal for TohoTenax to provide expanded productioncapacity to a market hungry for the versa-tile carbon fibers – right on schedule in thesummer of 2006. ■

The name Hirtler is most likely familiaronly to insiders, but everyone knowsthe products made by the company.

Hirtler was founded in 1887, with its head-quarters in the corner of Germany flankedby the Black Forest, Alsace, and Switzerland.Since 1989, Hirtler has belonged to Beiers-dorf AG, for which it has since been pro-ducing the company’s soap products –including brands such as 8x4, Eucerin, andNivea, for example. With a daily productionvolume of up to 80 tons of soap base and upto 80,000 bars of soap, Hirtler is one of thelargest soap manufacturers in Europe.

Soap production is a multistage processrequiring a high degree of automation toguarantee a consistently high quality level.Until 2000, the automation solution waslargely based on conventional control systemtechnologies, together with some Simatic S5controllers. However, Hirtler realized thatthe time had come to move on to the nextdevelopment step and implement an inte-grated process control system that wouldnetwork all production processes and offera modern, intuitive user interface.

Because Hirtler had had a positive expe-rience with the existing Siemens solution,

Soap production with Simatic PCS 7 at Hirtler

Brand QualityHirtler, a soap manufacturer in southern Germany, provides a good example forthe gradual modernization of a complex production process to achieve higherquality and greater productivity. The company has equipped its productionfacilities with an integrated automation platform based on Totally IntegratedAutomation and Simatic PCS 7. The uniform automation solution for allproduction sectors also provides the perfect foundation for the seamlessintegration of production and management.

migration to the latest generation of theSiemens automation technology was a log-ical step, and the company chose theSimatic PCS 7 process control system.Hirtler already had a long-standing andsuccessful relationship with Siemens, espe-cially the branch in Freiburg, and this rela-tionship played a decisive role in the deci-sion to adopt PCS 7. Siemens also won thecontract to modernize the automation tech-nology, which would be implemented bythe Freiburg office.

Step by step

The first phase of the project was the build-ing of a new spray tower to extract moisturefrom the wet soap at elevated pressure andtemperatures. This process, which is con-trolled by Simatic PCS 7, produces a soapgranulate that forms the basic ingredientfor various products. A PCS 7 operator sta-tion is installed in the plant control room,enabling the extensive display of all the rel-evant process data, and therefore completecontrol over the system.

The second project phase began in 2002.This was the modernization of the processcontrol for lye processing. In this step, thelye produced during the wet soap manu-facture is conditioned for further process-ing into glycerin and salt. This process stepwas automated with Simatic PCS 7, and also

has its own control station. In addition, afine-modular ET 200S distributed systemwith motor starters and Micromaster fre-quency converters was used. Of particularadvantage was the distributed structure inwhich the motor starters were installedlocally and linked to PCS 7 directly via Profi-bus DP. This approach not only reducedinstallation costs but also considerablyshortened the time to commissioning.

In 2004, the boiler room and grease tankstore control were scheduled for modern-ization. In this section, different greasemixtures are produced by recipes and then,with the aid of caustic soda, turned intosoap at approximately 90 ° Celsius.

Several stations were installed for theoperation and monitoring of the processes,distributed throughout the productionline. A redundant OS server pair was imple-mented, which records the system datawith a high degree of availability, and putsthem at the production clients’ disposal.Automated processes have replaced thelargely manual operation of the plant, andindividual processes in the plant can beoperated by touch panel PCs. Today the

recipes for the fine mixture can be loadeddirectly from a database and copied intothe process control system.

From single units to a comprehensive system

The decisive development step at Hirtlerwas the integration of all existing individ-ual units into a factory-wide productioncontrol system. For this, the operator sta-tions were replaced by PCS 7 clients, and allautomation systems connected to the exist-ing operator stations, which thus took onthe function of central servers. In 2004, allproduction lines for soap manufacturingwere connected to the system, as were thepower control center and the monitoringsystem for the ambient conditions. Now,all operating data and fault messages con-verge at one place, in line with the conceptof Totally Integrated Automation.

Perfect teamwork

The modernization of the production pro-cesses at Hirtler was by no means an easytask. Since production had to continueunhindered, precise planning and sched-

uling were necessary for every project step – otherwise, for example, the entireconversion of the boiler room could nothave been completed within a mere twoweeks. But the long and close partnershipbetween Hirtler and Siemens Freiburg paidoff. In a process lasting almost four years,Hirtler, together with the help of Siemens,was able to achieve the ambitious goal ofreplacing an outdated control system thatrequired numerous manual operationswith an automatic process control system.

That is not the end of the story, however.Hirtler is already planning the next logicalsteps. For example, an IT Historian data-base is to be set up, which will collect andarchive all the relevant data for the MESlevel, so that these are available for furtherevaluation and use by other systems. ■

P roven partners are important in achiev-ing process reliability, and DyStarrelied on its well-established relation-

ship with local system integrator andSiemens solution provider BST Buck Sys-temtechnik for the modernization andexpansion of the plant’s production capac-ity. BST already had extensive knowledge ofprocess automation from its long years ofcollaboration with DyStar, and was quitefamiliar with the locally installed systems.

In cooperation with BST, DyStar decidedto automate the new production line (knownas Unit 6) with the Simatic PCS7 process con-trol system, and to implement a batch sys-tem with Simatic Batch. At the same time,the controls in the existing plants were tobe changed over to PCS 7, which made amigration from the existing Teleperm Msystem necessary. Thanks to the proven

migration strategies from Teleperm M toPCS 7, the majority of the existing distrib-uted systems could be kept in place – a keyadvantage of the chosen solution. Most ofthe field devices are connected via ProfibusPA directly to the control system.

The aim of the upgrade was to create anintegrated solution that also included thelaboratory. In addition, the technical con-ditions had to be created to link the pro-duction control to SAP and the MES level ata later date.

Recipes with a high degree of repetitiveaccuracy

The DyStar recipe system, based on SimaticBatch, was one of the first of its kind in thechemical industry. To optimally exploit thesystem’s flexibility, the sample processingwas also integrated through Simatic Batch.

New process control technology with Simatic Batch for dye production at DyStar

Dye Exactly According to Recipe

With more than 4,000 employees in 70countries and quality products andservices, DyStar is one of the world’sleading providers of textile dyes. In itssynthesis plant in Brünsbüttel, thecompany produces 25,000 tons of dyes inabout 200 variations each year

Sometimes the expansion of production capacity is a good opportunity to bringthe entire process control system up to the state of the art. This was the case atDyStar in Brünsbüttel, Germany, where a completely new dye apparatus wasautomated with the Simatic PCS 7 process control system. At the same time,part of the existing plant was migrated from Teleperm M to Simatic PCS 7, andone of the first recipe systems with Simatic Batch was implemented.

obtain a standardized system solution, the15-year-old Teleperm M process controlsystem of the other production lines, alongwith all the recipe control computers, alsohad to be converted to PCS 7. The softwarestructures of the new plant – an alreadyfunctioning system – can be used as a basisfor the conversion. One production lineafter another will gradually be converteduntil an integrated, modernized processcontrol system is ultimately implementedthroughout the facility.

Established technology under newmanagement

Most of the existing plants have now beenmigrated. The new plant, Unit 6, has beenin operation since July 2004, and haspassed the tests of daily production withflying colors. The process begins with entryof the recipes developed in the laboratory.Dr. Henning Kado, head of process controland information technology at DyStar, is

very pleased with the new system. “We cannow create recipes easily and quickly withgraphic interfaces on PCs from the officenetwork,” he said. However, people whowork for the textile industry naturally needa high level of flexibility. Henning Kadocomments: “Thanks to the simpler recipecontrol, we can also change over our pro-duction faster, which brings us great advan-tages, especially considering the constantlychanging fashions and trends in the textileindustry. Here in Brünsbüttel, we have cre-ated a future-safe solution for the migra-tion of additional systems, and are also pre-pared for a later link to the ERP level via theMES.” ■

Research and practice at DyStar: Cooperation with Westküste TechnicalUniversitySince the systems at DyStar had to be migrated fromTeleperm M to PCS 7 during operation, the TelepermM process control system installed 15 years ago hadto be able to operate parallel to the new SimaticPCS 7 system for a certain time.

The problem was that data also had to beexchanged, and there was no interface between thetwo systems. DyStar discussed the problem with theautomation technology faculty of the WestküsteTechnical University in Heide, Germany, who agreedto analyze the subject matter and help find asolution. The result was a gateway that links theTeleperm M bus with the standardized IndustrialEthernet bus of PCS 7, and which therefore enablesoperation of the process control system from WinCC.

Both DyStar and the Westküste TechnicalUniversity are very pleased with the result. Thesuccessful migration is proof that the cooperationbetween industry and university was rewarding forboth parties.

All recipes are subjected to a plausibilitycheck, which guarantees a high degree ofquality reliability and repetitive accuracyfor the individual batch processes. Siemensdelivered the Simatic PCS 7 process controlsystem with OS operating clients, OS servers,and Simatic Batch servers. The systemsintegrator was responsible for the systemengineering, including the application soft-ware. The close partnership between BSTand Siemens paid off during the transition.Good preparation; extensive testing atSiemens and BST; and close cooperationbetween the DyStar process control tech-nology team, the systems integrator, andSiemens development all contributedgreatly to the system being ready for oper-ation within a very short time. Productiondowntime was minimized, and the Unit 6project was completed on schedule.

After successful commissioning of thecontrol system for the new production line,the second phase of the project began. To

Simatic PCS 7 and integrated Profibus solution at Merck

CommunicationHighlightsFrom automobiles and packing to facades – modern high-tech effect pigmentscan give practically any object the right finish. At its factory in Gernsheim,Germany, Merck, the market leader in effect pigments, operates a modernproduction facility for pearl luster pigments. For the first time, the automationtechnology for the process plant is based on Profibus and AS-Interfacethroughout.

Inspired bynature: The pearl

luster pigments fromMerck create the

metallic, shimmeringcolor effects that give

many products in thecosmetics and automotive

industry an expressive,fascinating finish

27

G lamour is very fashionable thesedays – whether in paint, lipstick, orhair spray. Pearl luster pigments are

providing brilliant highlights in more andmore products. To fully exploit the oppor-tunities of this growing market, MerckKGaA has considerably expanded the pro-duction capacity at the Gernsheim site overthe last few years. The construction of anew plant also gave Merck the opportunityto implement a new, future-oriented con-cept for the automation solution: the inte-grated networking of all devices via Profi-bus and AS-Interface.

Pigment production in Gernsheim wasoriginally based on remote I/O technology.The Iriodine plant, completed in 2001, wasautomated by Siemens solution providerControlmatic GmbH, using Simatic PCS 7and Profibus. The division of the plant into

standardized subplants, and a consistentlyimplemented redundancy concept withseparate control rooms as well as redun-dant OS and batch servers, turned theautomation solution into a fine example ofreliability and future-safe technology.

Totally networked production

In the production of pearl luster pigments,a mica suspension is first made from small,very thin mica plates and then treated withspecial chemicals. The process ends withthe finished effect pigment. The thicknessof the chemical coating determines the finalcolor effect. In addition to the actual pro-cess units, the plant also includes severaltank stores for the raw mica, the exhaustair, and the wastewater treatment.

The production includes continuous andbatch processes. Simatic PCS 7 with SimaticBatch is used for the batch control. Theplant’s process and terminal communica-tion buses networking the automation sys-tems and the central servers are designedas a redundant optical Industrial Ethernetring.

At the process level, the consistent useof Profibus and AS-Interface, as well as thestandardization of bus segments and switchcabinets, is a characteristic aspect of theplant structure. The plant is divided intoabout 130 standardized subplants. At theprocess level, every subplant consists of atleast one AS-Interface, Profibus DP, andProfibus PA bus. The use of Profibus extendsto the control units of the electrical switch-ing systems and the frequency converters.

The decision to implement Profibus wasreached primarily because of the numberof manufacturers who support Profibus,and the associated variety of devices andcontrollers available for this technology.However, the versatile application possi-bilities of Profibus were also an importantfactor. The entire plant, including all thesubunits, could be automated with Profi-bus. No other fieldbus system is capable ofmeeting those requirements.

With Profibus, safety-oriented processdata can be transferred in addition to nor-mal data via the Profisafe profile. Theintrinsically safe version of Profibus PAallows for communication and power sup-ply of process instruments through a sin-gle bus channel, and also enables access tostatus, parameter, and diagnostic infor-mation; central access to all devices fromthe control room; and central data storage.

In addition, planning, installation, andmaintenance expenses as well as the spacerequirements for wiring are reduced. Mod-ifications can be made to the plant anddefective control components replaced eas-ily during operation.

Redundancy – in the rooms for the con-trol technology, in the process control sys-tem, and at the operator station level – pro-vides maximum availability, so that theplant carries on operating without prob-lems when a controller or individual com-ponent fails. Thanks to several redundantserver pairs with multiclients, the wholeplant can be operated from each of theoperator stations even if different serversare involved in the processing of the orders.The redundancy concept is completed byeight highly available Simatic 417 systemsand redundant batch servers.

Satisfying results after two years inoperation

The tight time schedule, with just 12 monthsfrom the beginning of planning to the startof production, shows that Profibus is ide-ally suited for use in process technology.Although field devices from a total of 10 dif-ferent manufacturers were installed in theplant, all devices were integrated quicklyand easily into the control system with theSimatic PDM process device manager.

The experience from two years in oper-ation has been extremely positive: the highexpectations for the fieldbus technology,and especially Profibus, have been fullymet. Profibus proved to be a simple andlow-cost solution in terms of planning,installation, and operation. The personnelat Merck have quickly accepted the newautomation solution, and come to appre-ciate the user friendliness of the system.The central access to all devices has revo-lutionized maintenance work, reducingtime requirements and raising efficiency,despite the increasing complexity of thedevices. The new fieldbus solution alsoholds the advantage over the conventionalremote I/O solution, as a study at Merckrevealed. Despite slightly higher device costs,considerable savings could be achievedthrough simplified engineering and easierassembly of the systems. ■

closely involved in the development ofSimatic technology and Totally IntegratedAutomation.

This great wealth of experience was oneof the essential elements in Finze & Wag-ner’s favor, especially considering that onlythe Christmas 2003 and Easter 2004 vaca-tions were available for the conversion ofthe four production lines. In order to keepto this tight schedule, the individual pro-duction lines were first recorded, all therelevant controls read out, and a specifica-tion compiled. These data provided thebasis for a shadow system for every pro-duction line, including all the wiring and

CASE STUDY

Nestlé places great emphasis on maintaining uniform high standards worldwide, whether in terms of productquality and safety or the efficiency of operations and production processes. That is why the company iscurrently networking all its production sites in a common ERP system within the scope of the Globe project.That was also one of the main reasons behind the decision to equip the production facilities at their Weidingsite in Germany with a new process control system that is modular and scalable in structure, and that meets allthe requirements of modern production automation: Simatic PCS 7.

F rom the Weiding factory, the companysupplies the whole of Europe withNestlé baby and toddler food. Up to

1,000 jars and bottles per minute are filledon the production lines, especially forNestlé’s main brand Alete. In order to reli-ably achieve these production figures withconsistently high product quality, optimumresource efficiency, and maximum avail-ability, Nestlé sought a new automationsolution to replace the existing Simatic S5systems. Important considerations included,in particular, the company-wide network-ing of all processes, trouble-free interac-tion with MES solutions, and the possibility

of smooth integration into the global ERPsystem. Of course, the new system also hadto guarantee full traceability of batches, asprescribed by the new EU directive in effectsince the beginning of 2005.

Tight schedule for implementation

After extensive review, Nestlé chose a com-bination of the Simatic PCS 7 process con-trol system and Simatic Batch. The systemsintegrator, Finze & Wagner, was contractedto design the new automation solution inJuly 2003. The Siemens solution providerhas about 20 years’ experience with Siemensproducts and solutions, and has been

system installation. Proven software com-ponents from the process industry could berelied on for the engineering. The softwarefor linking the available drives was writtenin SCL (Structured Control Language),which is part of the engineering system ofSimatic PCS 7. According to Frank Lang-hauser, project manager at Finze & Wagner,the team was able to meet the tight sched-ule due in large part to the close collabora-tion with the Siemens software developers.“They were there for us around the clock,”said Frank Langhauser.

The production processes of the realproduction lines were simulated on therespective shadow plants, in close cooper-ation with the plant operators in Weiding.Parallel to this, all 20 plant operators weregradually made familiar with the new sys-tem. This made the transition to the new sys-tem much easier. Simatic PCS 7 and SimaticBatch were soon well accepted, as JohannesSchmid, project manager at Finze & Wag-ner, confirms: “Many employees were com-pletely familiar with the system within ashort time and often developed their owncreative solutions.”

Rapid commissioning

After the house technicians at Nestlé hadlaid all the necessary Profibus cables and

changed the old contactors and relays, theentire shadow plant was set up at the Wei-ding factory in a single day, just beforeChristmas. The first production line wasconnected to the new system right away.Thanks to the excellent preparations on siteand in the shadow plant, the migration tookplace without a hitch. The loop check andtrial runs were completed within just fourdays, so that the plant was able to go intoproduction on time at the end of the Christ-mas vacation.

The experience with the first two pro-duction lines was also a great benefit for fol-low-up projects. Hartmut Bühne, head ofelectrical engineering at Nestlé in Weiding,said, “We got faster with every productionline: where the downtime for the pilot proj-ect was three weeks, we only needed twoweeks for the last production line.” This canbe explained by both the classic synergyeffect, and the fact that certain work such asthe integration of the tank farm or thewhole packing line had to be done onlyonce.

More flexibility in production

The new solution not only reliably meetsthe primary requirements of Nestlé. It alsooffers many other advantages. “We can nowdrive all the lines from every workstation,

The recipes can be adapted with the graphic recipe editordirectly in the control room

also in cross traffic. We also save a lot of set-up time with the possibility of adapting pro-duction processes independently with thegraphic recipe editor in the control room,”explains Bernd Hübner, production man-ager at Nestlé in Weiding. The integratedbatch system helps cope with the constantlygrowing product variety. Nowadays, notonly carrots, potatoes, and apples are pro-cessed, but also fish and artichokes, oftenin relatively small quantities and exactlyaccording to the specific order. “We are onour way to just-in-time production,” saidHübner. At the end of the current MES inte-gration project, the site will be connected tothe Globe system. This complete integra-tion, from the management to the processlevel, gives Nestlé the opportunity to sig-nificantly increase its productivity. ■

“Ten years of experience have brought us toespecially admire the reliability of Siemensinstruments. Today, I was most interested inwhat new developments had taken place inweighing technology. The event was a greatsuccess, but it was only a supplement to thevery good product information policy atSiemens. Siemens regularly stages effectiveinformation events at our company, and wehave very professional local contacts. Thehigh-quality social program was very inter-esting, too.”
