“Which control system offers me the most benefits?” or “Which controller is the best choice for my appli-cation?” Plant operators and manufacturers often face the challenge of having to select from a huge range of different controllers and control systems in order to find the product that is best suited to their needs.
With its extensive portfolio, Siemens offers solutions for a wide variety of applications. LOGO! is a cost-efficient yet high-performance solution. In terms of hardware and software it is especially well suited to simple applications and smaller-scale projects. Thanks to the CMR, CMS, and CMK communication modules, various tasks for a wide range of applications can be carried out simply and expertly. Remote access is possible with a smartphone via the integrated web server and offers cost-efficiency in this performance class.
Where a larger set-up is required, the Simatic S7-1200 comes into play. It is configured within the TIA Portal engineering framework and may also include, for example, Simatic Basic Panels. For more complex
tasks such as complete production automation, the Simatic S7-1500 is the optimal solution.
Users often need more than just one automation solution, however. For example, the horse treadmill manufacturer Sascotec (p. 20) combines LOGO! and Simatic S7-1200. Bauer Inc. (p. 6) automates its aircraft tire inflation systems with the Simatic S7-1200 and uses the Simatic S7-1500 for customized testing systems. Thanks to the Totally Integrated Automation platform and the TIA Portal engi-neering framework, Siemens enables customers to exploit the benefits of the various products in their own appli-cations and within a development environment. What is more, the products are all tailored to individual customer needs. That means that manufacturers can use standard and custom-developed libraries to their advantage. This results in shorter development lead times, faster time to market, and ultimately lower engineering costs. And regardless of which performance class the controller is selected from, the products have worldwide availability and ensure reliable operation even in the most unusual applications.

“Inert’s value and the source of our competitive edge has always been making great products and continually working to improve and expand the features and perfor-mance they provide,” says Daniel Clay, CEO of Inert. “Flexible engineering for our OEM customers has also been critically important.” The Boston-based company supplies its products directly to its end clients as well as to OEMs, who in turn integrate the Inert solutions into their own plants and systems. For many years, the global market leader used controllers from different manufacturers in its production.
Flexible engineering is crucial to Inert
Moving made easy
Simatic S7-1200: Inert, a market leader in glove boxes, gas management, and solvent purification, is modernizing its systems, simplifying procurement, and increasing production efficiency with solutions from the TIA portfolio.
This presented Daniel Clay with a conundrum. On the one hand, Inert’s products were essential for its customers’ production machines, which were used across various industry sectors. However, its own innovation capacity was limited by the diversity of the controllers, which complicated procurement, manu facturing, and service.
Inert therefore chose to implement the Simatic S7-1200 controller and HMI panels from the Totally Integrated Automation (TIA) portfolio. Thanks to the TIA Portal

Clay adds that the Siemens engineers developed codes for operator control and monitoring. This proved a real added value: “We now use much broader terminology for the on-screen buttons to better serve users in our inter-national markets. It really has helped us stay one step ahead of our competition.”
Increased efficiency and savingsBoth Clay and Michael agree that the migration to the Simatic S7-1200 and Simatic HMI was the best move Inert could have made. Michael explains: “We can now carry out our software programming in-house again. Trouble-shooting and the development of new features are much easier and quicker. Fewer parts need to be ordered and held in storage, and training Inert’s service team only took four hours.” A further benefit of the implementation is remote diagnostics.
“Thanks to the range of controllers from Siemens, we were able to improve our time to market and we can now tailor our products to individual customer demands,” says Clay. “For example, we can now offer Modbus and Ethernet communications features. And we can program energy- saving functions and much more, too. Now that we have made the switch, we look forward to further improve-ments and innovation – this is what lies at the heart of Inert’s business.”

engineering framework, Inert was able to streamline the introduction of new features, significantly reduce time and costs, and increase flexibility to enable the company to customize its products. This was a crucial factor as Inert’s customer portfolio includes OEMs, top universities, government agencies, and Fortune 500 companies from around the world.
Increasingly complex engineering“With three controllers from two different suppliers and two different voltages typically used worldwide, we had to manage six different controller platforms,” says Timothy Michael, head of engineering at Inert, pointing to the pro-blems the company had to contend with before switching to the Siemens integrated solution. “This complicated our engineering and manufacturing as well as our downstream customer support and service.”
Over the years, engineering became ever more complex. Inert continued advancing its own product innovations, while customers came forward with specific requirements, as Michael recalls: “It started turning into a bit of a spider’s web in terms of different codes. To make matters worse, we were on our third external developer, and because everyone does PLC programming their own way, making a change in one place could result in unintended effects in the codes elsewhere. That made debugging and trouble-shooting issues extremely tedious and time-consuming.” Engineering and service costs rose and time to market increased. “We had reached the point at which a decision had to be made,” says Michael. “We needed a modern control solution that would help us advance our brand.”
The path to success“Siemens made it extremely easy for us to move to its TIA platform,” Michael continues. “The TIA portfolio and the integrated TIA Portal engineering framework convinced us of their worth, especially through their potential to solve the issues we had.” Siemens also supported Inert in modernizing existing codes and many other features – at no extra cost.
Another major challenge was timing as the engineers had less than two months to complete the migration.
“The engineers were on top of their game,” says Clay. “They had fully converted our codes in six weeks meaning that we were able to showcase our updated products at the American Chemical Society (ACS) trade fair with a fully modernized look and feel,” adds Michael. The enhanced look and feel were thanks to the HMI color panels. “We were thrilled with them – and so were our customers at the trade fair,” says Clay. “They are light years ahead of our old panels and open up a whole new world of possibilities.”

Aircraft tires are subject to extreme stresses when taking off and landing. A correct tire pressure is crucial to ensure passenger safety
Many drivers are driving on under-inflated tires and thus ignoring the known safety risks and reduced treadwear. However, they would be very alarmed if they were aboard a commercial aircraft weighing as much as 400 metric tons and learned that it had anything less than perfectly inflated tires when landing at 180 miles per hour.
For many airlines and armed forces using the 5012 Auto-matic Tire Inflator system from Bauer Inc. in Bristol, Connecticut, proper tire inflation is never in doubt. The product forms part of the company’s diverse range of test solutions for fuel, lubrication, pneumatic, and electro-mechanical applications that it supplies to the aviation industry.
Their key requirements include reliable and rapid support combined with the latest test and maintenance equipment. Only then can their ground crews maximize efficiency and pro ductivity and keep their aircrafts flying safely and eco-nomically. This includes tire inflation using pure nitrogen from a cryogenic source – a delicate procedure that must be conducted carefully. Excessive pressure can damage the tires, which each cost US $5,000, and ruin the safety cage of the inflation system, which is worth much more. Further-more, an exploding tire may require investigation and possibly even entail a report to the regulatory authorities.
State-of-the-art technologyAs a result, several years ago, Bauer Inc. decided to update the controls of its tire inflator system. Although the sys-tem’s filling algorithm worked just fine, the implemen tation of the latest PLC technology would enable Bauer to monitor additonal parameters and execute various recipes for several different aircraft tire makes and models. This allowed Bauer to offers its customers additional features, while increasing their satisfaction.
Exact pressure for perfectly inflated tiresSimatic S7-1200: Using new controller technology, Bauer Inc. can now deploy its tire inflation system with considerably greater flexibility and reliability.

Time for a changePreviously the filling process was manual and involved several time-consuming steps: operators had to partially inflate a tire, then gauge how much more pressure was needed. If the pressure was too high, they would have to release the extra nitrogen. This was repeated until the specified inflation level was reached – ultimately a waste of money.
Bauer therefore chose to update its system with a solu tion from Siemens, selected specifically for its latest Simatic PLC technology together with the TIA Portal engineer ing frame-work. Bauer already used the Siemens S7-1500 Controller as the standard for its custom aircraft component test systems, so it was familiar with efficient engineering using TIA Portal. The company also valued the Simatic intrinsically-safe I/O, which enables the tire inflator to be installed in areas with gas and dust explosion hazards.
The future, todayThe Simatic S7-1200 Basic Controllers are at the heart of Bauer’s automation solution. For the operator interface, the company chose a nine-inch Simatic HMI Comfort Panel, which covered all the necessary functions and was ideal for the tire inflator system. A further require-ment was connecting a barcode scanner. This enables an operator to input a tire’s make and model quickly and without errors, so the controller could retrieve the correct inflation recipe from its catalog. Via the USB port on the Comfort Panel, a label and report can also be printed out at the end of the inflation procedure and then attached to the tire.

Flexible functionsProgramming and simulation with TIA Portal meant that the first newly-equipped unit was completed several weeks earlier than usual. The new, considerably more extensive inflation system can also be upgraded, thus further increasing Bauer’s competitiveness.
When it came to programming with TIA Portal, Bauer was able to leverage the library of function blocks as well as its own customized solutions based on the Simatic S7-1500 platform. Thanks to the Simatic S7-1200’s integrated V2.0 PID technology, the solution can be easily configured for any number of control loops to read the system’s 20 parameters.
Verification that the tire inflation algorithm was correctly ported from the old to the new system would have previ-ously taken two weeks alone. Using TIA Portal, Bauer’s software team completed the process in just two days.
Simulations for feedbackThanks to the HMI simulations created using TIA Portal, Bauer can easily present design concepts to customers all over the world, ensuring that they are also happy with the look and feel. The flexible nature of TIA Portal has enabled Bauer to set a new design standard that can easily be adapted to future products.

Locally sourced food is a trend. Short transport distances guarantee fresh-ness and help protect the environ-ment. Marienhöher Direktvermarktung, based in Waldkirchen in the German Vogtland region, is profiting from this trend, which has enabled the com-pany to continuously expand its pro-duction in recent years. The farm has a herd of 700 cows and the direct mar-keting of its dairy and meat products have grown into profitable separate business units under one roof. In the past, it was difficult to determine how much energy each unit was using. Yet power consumption is a major cost factor, especially in the direct marketing of dairy, cheese, and meat products. But as managing director Heiko Hölzel emphasizes, saving at the expense of quality was out of the question: “That would be contrary to our tried-and-tested recipe for success.” Measures previously adopted to conserve resources included oper-ating a biomass power plant and using LEDs for the lighting of cattle sheds and production facilities. “We do, of course, know that further savings are possible but where is the best place to start?” This is the question that electrical engineer Ulrich Bauer asked himself. To answer it, Bauer first needed to know how much energy the existing systems were using.
Discovering where energy is usedBauer decided to start by metering the actual consumption at the central power infeed. He found the Simatic S7-1200 controller and new Energy Meter module to be cost- efficient and easy to operate. The CPU 1212 was able to manage the planned tasks. The controller is avail-able as a highly cost-efficient Starter Kit together with a KTP400 Basic Panel and the TIA Portal engineering soft-ware. The controller processes the consumption data recorded by the Energy Meter module and transmits them to an easy-to-read display on the Basic Panel. The only additional items needed are current trans-formers for the three phases. The current, volt age, and power output data recorded on the panel can be sent to a PC for further analysis.
Assigning consumption data accuratelyDetailed knowledge of the plant operations and load profiles of the exisiting machines and systems enabled Bauer to assign the consump-tion curves accordingly. “Monitoring overall consumption is the first step. But the results have certainly helped us in several different ways,” Bauer comments. The capability to break down consumption data across the farming and direct marketing opera-tions is just one aspect. Bauer says,
“The most important finding was that the main circuit-breaking system of the plant, which has grown over the years, is now reaching its limits and urgently needs to be upgraded. An overload could lead to a refrigeration
The key to cutting energy costs was recording the actual consumption of the central infeed
breakdown and the failure of indi-vidual system components. Bauer also discovered that the reactive power compensation was no longer up to the job. Although the proportion of reactive power is low, improved cor-rection could nevertheless generate savings.
Motivation helps savingThe recorded consumption data are currently analyzed on a monthly basis. The analysis of plant operations alone has enabled the company to already achieve significant savings. Hölzel comments: “If we can show staff how much energy a running pump uses unnecessarily, they pay far more atten tion to avoiding waste consump-tion. The certainty of being able to

achieve energy savings has the advantage that it motivates workers to use resources responsibly far more so than any other general plea.”
The opportunities offered by the new technology have sparked Bauer’s interest in implementing additonal energy management measures. In order to further increase transparency in power consumption, he is planning
siemens.com/[email protected]
to improve the consumption metering with additional Energy Meter modules. In the long term, he is considering installing switching systems to avoid consumption spikes. The use of Simatic controllers and the Energy Meter offers the ideal basis for further expansion. The Simatic S7-1200 with the CPU 1214 or higher, for example, enables the connection of eight Energy Meter modules (two modules can be con-nected to the CPU 1212). Consump-tion data can additionally, or alter-natively, be displayed via the web server integrated into the controller. This means users can read power consumption figures from the office at any time. A particularly interesting feature is that diagnostic messages can be analyzed on the same PC for maintenance purposes. All that is required is an Ethernet connection to the in-house network or an Internet connection to enable remote access.
Transferable solutionSiemens offers the program to connect the Energy Meter to the Simatic S7-1200 controller in order to view consumption data on the Basic Panel as a free-to-download appli-cation example. The application was programmed by Christoph Bauer in collaboration with Siemens Industry

Online Support, optimized based on the experience gained at Marienhöher Direktvermarktung, and documented in such a way that even users with no programming skills can get a similar application up and running in just a few hours. “The high level of interest we have received in this solution has shown us that using the Simatic controller can also be beneficial in appli cations with minimal automation requirements. Automated energy data metering also provides transparency regarding the energy consumption of older plants that have been expanded over time. Furthermore, the solution is so easy to integrate that hardly any PLC expertise is required,” explains Christoph Bauer.

Many LOGO! programs use function blocks with parameters. There are several ways to adjust them either directly on the PLC or on an external text display.
Adjusting parameters during operation
The following briefly outlines how values set during commissioning, for example timer or count functions, can be adjusted “live” with LOGO!.

There are several ways to adjust these parameters without changing the actual program, either directly on the LOGO! controller or on an external text display.
The “Set Parameter” function is suitable for service technicians. Displaying the required parameter in the message text is easier for operators, however. In both cases LOGO! remains in RUN mode. So what are the differences and respective advantages?
Our demo program includes three function blocks with parameters. In the following, we will adjust the counter start value in several ways – Figure 1.
When a LOGO! controller is in RUN mode, the way to exit the start screen (by default the date and time – Figure 2) is by pressing the ESC key. This returns you to the main menu, from where you can access the desired function block with the operator control sequence shown.
Select “Program” and “Set Parameter” to open a list of all function blocks that have parameters. If you assign the function blocks informative names during program-ming, it will be much easier to select the right block later on.
If you make the change from the text display, you must select “LOGO! Settings” (Figure 3) as an interim step to reach the main menu.
13
GO! 1/2017

In our example (Figure 4) the “Counter” block is selected with “OK” or the cursor-right button, and all parameters of that block are displayed.
After selecting the desired value – here the start value (STV) – you can adjust it and click OK to confirm.
Then keep pressing the ESC key until the date and time reappear.
This parameter change can also be made in password-protected programs. If there are function blocks with parameters that the user is not permitted to change, you can lock the individual function block in the block properties by checking the “Protection Active” box – Figure 5.
The function block is then no longer displayed in “Set Parameter” mode.
If the user is permitted to change only one parameter in a block with multiple parameters, there is a smart solution:
Protection is activated for the block in question, meaning it can no longer be selected in “Set Parameter” mode. The specific parameter required is included in a message text (Figure 6). The value can then simply be adjusted in the message text.
Figure 4
Figure 6
Figure 5

GO! 1/2017

The relevant message text must be active on the display – Figure 7. Then keep pressing the ESC key until the cursor is displayed in the text.
⇨ Move the cursor to the corresponding parameter and confirm with OK
⇨ The parameter is then activated and can be adjusted using the cursor buttons
⇨ Confirm with OK. The new value has been set
If a message text displays a parameter that may not be changed, the message text itself can be protected so the value cannot be accessed.
Incidentally, it is possible to change parameters by way of the message text as well as via the web server. Changeable values are displayed in blue on the web server – Figure 8.
This means switching times can also be easily adjusted using a smartphone without having to access the control cabinet, as long as the LOGO! is connected to a wire-less network and the web server has been enabled.

Relaxation, stimulation, detoxing, recharging – there are many reasons to visit a wellness resort. But for visitors to really feel the benefit, the facility must convey a sense of comfort and relaxation that enables them to forget their troubles.
The Italian company Starpool, based in Ziano di Fiemme, designs and installs equipment for wellness centers all over the world. “All our products are the result of more than 40 years’ experience, as well as long-standing collab-oration with scientists. They have helped us to investigate the beneficial effects of using spas, a tradition that dates back millennia and continues in the present day, including the latest that multimedia technology has to offer,” explains managing director Riccardo Turri.
An ambience of well-being Technology plays a key role in solutions Starpool offers to the hospitality industry and private clients. The Italian company relies on LOGO! to optimize the ambience of wellness facilities in spas. In addition to controlling heat
sources, the microcontroller adapts lighting and access control systems to individual requirements. It also manages consumption in order to save energy, detects malfunctions promptly, and issues alarms when needed. Simatic Comfort Panels control a range of applications within the facility in a targeted way – whether for indi-vidual saunas or baths, or complete wellness areas.

“Right from the start, Starpool utilized innovative tech-nology to improve the functionality and energy efficiency of wellness facilities,” Turri continues. “The integrated communication functions of Siemens devices have been a great help to us.” As part of the set-up, all Starpool prod-ucts can also be controlled wirelessly. All data, alarms, error messages, and diagnostic functions can be trans-mitted to any wireless mobile device.
The specially programmed Energy Efficient software package controls the temperature of all Starpool applica-tions. The facilities’ automatic door closure mechanisms are also linked to the system and can be customized. This means that in normal operation, as much as 20% can be saved on energy bills.
Data ensure profitabilityThanks to the integrated web server, data acquisition by LOGO!, the Ethernet connection, and the client app that helps connect to mobile clients, large volumes of data can be stored and managed. Starpool’s Eco Spa Technology software also provides optimal management of energy consumption, including remote diagnostics. Therefore, maximum power consumption levels specified for opera-tion are not exceeded, resulting in long-term energy savings.
The consumption, alarm, and access data recorded by LOGO! help to optimize the operation of wellness facilities. This information enables operators to respond more closely to their customers’ needs and demands, and as a result, increase their own profitability. “Our investment philos-ophy incorporates innovative products and projects,” Turri adds. “We help our customers implement new ideas for their businesses. In Siemens we have found a reliable, long-standing technology partner, one who is also willing to respond to market trends with us.”
That collaboration has helped Starpool to gain a foothold on international markets – based on features such as the use of globally available, reliable technology and the capa-bility to control facilities anywhere in the world remotely.
“The challenge still remains,” Turri concludes, “and we are already undertaking new studies and projects aimed at promoting harmony of body and mind on the basis of heat, water, and relaxation. One example of this is our new Nu Relax system, which combines traditions dating back mil-lennia with the latest scientific research. In ‘Floating,’ the sense of weightlessness is paired with guided medi tation techniques. Here, the connection between the power of the mind and technology promotes human well-being.”

Craft beers are soaring in popularity – not least in the United Kingdom. That is why increasing numbers of the country’s micro-breweries are focusing on craft-brewed beers made from the finest ingredients, some featuring unconventional flavors. According to the Society of Inde-pendent Brewers (SIBA), independent breweries have already sold more than 50 million liters of the tasty alter-native to mass-market products!
So what is driving these breweries that are bravely taking on the large multinationals? Originating in England in the 1970s and spreading to the US in the 1980s, micro- breweries are all about craftsmanship and individuality. And they are certainly onto something. There are now more than 4,500 micro-breweries in the United States alone!
Dave Bailey is the founder of the Hardknott micro-brewery in Cumbria in the north of England. Even after 12 years in business, his objective is still to brew the very best beer he can for his customers’ satisfaction and enjoyment. His ales bear names such as “Azimuth” and “Intergalactic Space Hopper.” To ensure he measures up to his customers’ stan-dards, Bailey and his team continue to innovate and invest with the assistance of Siemens technology.
LOGO!: British brewery Hardknott utilizes the logic module to automate its brewing process – and makes one of its key elements more efficient and reliable.
A key component“Control of the fermentation temperature helps to consider-ably improve the quality and consistency of beer,” says Bailey. “It takes place over several days and on a practical basis the process cannot be watched continually.” Tem-perature control sys tems can be expensive and complex. That is why micro- breweries tend to use fairly rudimentary on/off controls, or even manual ones. These are, by defini-tion, not overly accurate. Yet automatic temperature moni-toring and control are essential for Bailey, so Hardknott is now using LOGO! 8 from Siemens to make this important part of the brewing process more efficient and reliable.
“We have successfully used discrete controllers for the past five years,” says Bailey, “but an inability to integrate with other equipment easily, a lack of a logging facility, and the rising cost of replacement units when failures occur encouraged us to seek out an alternative solution.” Hardknott was already using LOGO! to control a keg washing solution so the logic module seemed to be the obvious choice to control the fermentation process.

value. Precise regulation is key. LOGO!’s logging facility and trend display courtesy of an HMI screen give Hardknott a perfect, intuitive set-up to keep the temperature just right. Data are logged on an SD card. They can then be evaluated on a PC, allowing the control process to be analyzed and optimized. This makes the brewing process stable and reproducible.
“Using LOGO! to control our brewing process has already proved to be beneficial because it offers flexibility, scal-ability, and the potential to be seamlessly networked with other Siemens technology,” says Bailey. Featuring a large display and full communication options via Ethernet, the controller is easy to set up and operate. The web server integrated in LOGO! requires no special HTML program-ming knowledge so accessing the controller is simple. Remote communication via the wireless cellular network rounds off the capabilities and enhances the potential range of applications for LOGO!.
Solutions to meet every need“There are areas that we will optimize, such as the system’s resistance thermometer detector resolution,” says Bailey, with an eye to the future. His aim is to develop a truly commercial solution that can also be used in other micro- breweries. “We wanted to meet the functional demands of this new generation of breweries, yet remain affordable,” explains Sara Nichols from Siemens. “Working closely with these brewers, we have developed a solution to support all the requirements of the fermen tation process, including remote access, data logging, and app support.”

Agriculture dominates life in the rural, German town of Stavern in Lower Saxony. Horses are a very common sight, as are the countless stables where horses are looked after.
“A horse needs a good deal of exercise to stay strong and healthy,” says Oliver Sandmann, the CEO and driving force behind Sascotec. He was born in the area and grew up with horses. He is also a man of ideas, one of which is a horse treadmill known as Horsetrainer, a device com-parable to the treadmills we know from the gym. In a country as densely populated as Germany, such a device ensures horses get enough exercise and stay fit. What is

more, it can also offer injured horses a way to recover and get back into shape.
“These days, many stables simply don’t have enough space to give their horses the exercise they need. There is also a risk that valuable show horses may injure themselves on rough ground and be forced to miss competitions,” adds Sandmann.
The Horsetrainer makes exercise possible under controlled conditions. Special rubber dampers ensure a soft surface similar to a forest floor, while a hydraulic tilt function even

simulates going uphill. But most importantly, the horse can trot without being led or ridden by a human. That saves staff costs at the stable and keeps the horse in top physical condition.
Pay-per-use as a business modelJust selling or renting out the Horsetrainer did not seem like the ideal business model to the resourceful, passionate horseman. He was more interested in a solution that involved marketing use of the machine rather than the device itself.
“Customers rent the Horsetrainer together with 100 hours of use. The actual use time is recorded and charged at the end of the month. Stables can also generate revenue with it by renting time on the Horsetrainer to their cus-tomers. They log in to our system on their smartphones and the treadmill is then unlocked for the booked time,” says Sandmann, explaining the concept.
A small-scale Internet of ThingsTo put this pay-per-use concept into practice, the Horsetrainer needed a digital drive controller and capa-bility to communicate wirelessly with Sascotec. Sand-mann discussed the matter with Olaf Janscheidt, his Siemens representative, who immediately thought of LOGO!.
The solution they developed features a LOGO! control system from Siemens’ microautomation product line. This compact logic module was specially developed to enable intelligent control of small machines. It can be programmed easily using LOGO! Soft Comfort software.
A combination of LOGO! and the CMR 2020 GPS module turned out to be perfectly suited for the Horsetrainer. It gave Sascotec the option of remotely controlling every single one of its machines using the text messaging service while simultaneously transmitting specific parameters such as operating hours, for example. “This lets us know exactly when and how long every machine is in use, so we can bill accurately based on these times. It also provides actual use information that makes selective maintenance possible.”
What is more, the CMR 2020 features GPS and transmits the actual location of each machine to Sascotec. All in all, the Horsetrainer is a practical example of a business model closely related to the widely discussed Internet of Things (IoT) of the future.
The built-in LOGO! logic module controls the Horsetrainer’s drive unit via a Sinamics G120 frequency inverter. A special safety function prevents injuries by guaranteeing that the treadmill shuts off automatically if a horse stumbles and can no longer move within the available space.
Better information brings new opportunitiesThe pay-per-use system has been well-received, says Sandmann, who is already working on taking his idea even further. His latest concept is a similar horse training device, the equine water treadmill. Here, the horse exercises in water, which produces resistance for effi cient training together with buoyancy to protect its joints.
The required control functions are performed by the Simatic S7-1200 Basic Controller, which is also connected to a Sinamics G120 frequency inverter that adjusts the speed of the drive motor to match the selected program. The system is operated using a KTP700 Basic DP control panel. This graphic user interface enables operation via built-in pushbuttons or directly on the seven-inch TFT touch display. All of the components communicate via Profinet and can be easily configured using TIA Portal.
For his next project, the creative horse enthusiast is thinking about a mobile version of the horse treadmill. And he is looking for ways to convert the muscle power of a trotting horse into electrical power. A Siemens control system is bound to be a key part of this endeavor, because
“programming the machine’s control system was child’s play,” says Sandmann. “TIA Portal takes no more than two hours to master. Working with it then becomes entirely intuitive.”
Customized Siemens technology is at the heart of the electronic drive control for the Sascotec horse treadmill

When designing the new LOGO!Power supply device line, the mounting width was reduced by 18 mm in all performance classes. The device can be mounted on walls and standard DIN mounting rails. The load current can be recorded at any time via an integrated measuring point for deter-mining the power requirements, thus eliminating the need to interrupt the circuit.
For currents of up to 4 A, the new LOGO!Power line offers optimum per-formance in compact spaces at tem-peratures of between –25°C and 70°C. Efficiency of up to 90% over the entire load range and no-load power losses of less than 0.3 W ensure economical

In addition to the new technical fea-tures and reduced mounting width, the 12 V/0.9 A and 24 V/0.6 A device versions have been added to the product range.
Thanks to extensive certification, all the devices can be used in Europe, the US, and Canada, as well as in haz-ardous areas and on ships. To further increase availability, the LOGO!Power units can be combined with redun-

In the past, moving data to or from control systems in a plant had to be done separately for each control system, which involved the manual insertion of cards and con-necting to each one individually. With the Simatic Auto-mation Tool, all connected control systems can now be accessed at the same time. Simply connect a laptop con-taining the Simatic Automation Tool to the control system network with a Profinet cable to complete a range of tasks centrally and without TIA Portal! Once all the machines have been set up and the plant is due to be commissioned, the Simatic Automation Tool provides support with the following features:
• Scan of a Profinet/Industrial Ethernet plant network and identification of all devices connected to the network
• Flashing LEDs help to physically locate the CPU• Address assignment (IP, subnet, gateway)
and station name change (Profinet device)• Program download to CPU (no fail-safe programs)• Operating mode change RUN/STOP • Performance of a CPU memory reset• Backup/restore projects (no fail-safe projects)• Transfer of date and time settings in a CPU to UTC
in your PG/PC• Upload of service data from a CPU• Reading the diagnostic log from a CPU• Reset of a CPU to factory settings (no fail-safe)• Update of firmware in a CPU and attached modules• Documentation and storage of configuration as – standard text.csv file or – an encrypted and password-protected
Simatic Automation Tool (.sat) file• Provision of a programming interface (API),
for example for automated use of supported operations with C/C#
These features can be executed simultaneously at several S7 stations as a mass operation.
The Simatic Automation Tool is used to configure, operate, maintain, and document automation networks based on control projects created with TIA Portal software.
