Herzogenaurach, Germany. At the Press Conference ahead of the Hannover Messe 2018, concrete implementation of the Industrie 4.0 concept in the Digital Enterprise was presented in the form of six Expert Talks relating to selected sectors of industry. As part of our series dealing with the expert topics, this article looks at “DES – distributed energy systems”. The presentations to accompany the Expert Talks are available to download.
Today’s energy market is determined by three underlying challenges: Costs, security of supply and carbon dioxidereduction. Only a few years ago, answers to these challenges were few and far between. Today, practically all energy users are faced with the decision of which strategy is the right one to meet their specific needs. At Siemens this task of making the right choice on behalf of customers from across every sector of industry is in the hands of dedicated experts. They plan and install distributed energy systems, known as DES for short. The targeted use of renewable energies, combined heating and power stations, or the provision of storage solutions: Siemens plans optimized energy supply solutions and implements the projects – even including models which allow the customers to simply order an answer to their specific problem in the form of Energy-as-a-Service. Siemens deals with the nuts and bolts of the problem, from planning and installation through to operation. In this way, the challenges – costs, security of supply and carbon dioxidereduction – become long-term calculable variables in the business process of each individual energy consumer.
Distributed energy systems on Ventotene
One example of a distributed energy system implemented by Siemens was for the Italian energy utility company Enel on the Mediterranean island of Ventotene. The approach taken by experts from Siemens to solve the island’s power issues was to install a Siestorage type battery storage system. All the components were integrated directly into the island’s power network, permitting more economical and efficient operation of the entire energy system through the use of a smart controller. Siestorage additionally stabilizes the frequency and voltage of the local grid by using integrated converters. The scope of supply also included the transformers and low-voltage switchgear.
With an area of 153 hectares, the Mediterranean island of Ventotene is located some 100 kilometers south of Rome and is not connected to the Italian national grid. The island’s power supply formerly relied on four diesel generators and a number of photovoltaic systems. Today, interaction between the storage, generation and consumption of power is ideally adapted to the current requirement at all times by the smart controller for the island network, which was developed in cooperation with Enel. First and foremost, this allows more efficient operation of the diesel generators, as short-term peak loads can be covered in future by power taken from the storage system rather than by the generators. During off-peak periods, the diesel generators can actually be switched off entirely, saving fuel, extending their service life, minimizing maintenance costs and reducing the consumption of diesel, which itself has to be transported to the island.
Another aim of using battery storage as a back-up for Ventotene’s island network is to allow the integrated converter to compensate for frequency and voltage fluctuations, guaranteeing a stable network for the island. In this way, the network is prepared to meet future requirements such as the use of charging stations for electrically powered means of transport. Plans also exist to increase the capacity of the entire island network, allowing it to more easily absorb fluctuating energy levels derived from renewable energy sources. The storage system is also invaluable when the time comes for maintenance on the generators, which have to be disconnected from the grid to perform the necessary work. The system is then able to temporarily keep the island supplied with power. Should a grid blackout occur, Siestorage’s black start capability allows a controlled restart of the island network.

Fishing for data on the high seas - MindSphere Open Space Challenge at the Hannover Messe 2018: Who will develop the best ideas? For on-board fish processing for instance.
The IoT operating system MindSphere is currently a hot topic at Siemens. With the MindSphere Open Space Challenge, Siemens will be making a new departure at the Hannover Messe 2018. The Challenge will see creative minds get to grips with the requirements of customers such as Baader, which specializes in machines for fish processing. Visitors can look forward to an exciting contest staged directly at the show with only one winner of the best idea for new MindSphere concepts, apps and services.
Most people tucking into a delicious fillet of fish will probably not spare a single thought about how it made the journey from the Atlantic Ocean onto their plate. But it’s highly likely that one of Baader’s machines was involved – and in the future the cloud-based open operating system for the Internet of Things (IoT) might have played a part too. Baader builds machinery for processing fish at sea. The company is keen to give its machines on trawlers the ability to transmit precise information to shore in future about the type and extent of the catch while still at sea, which will be extremely valuable for the captain and the catch management team ashore. In future it will be possible for this data to be analyzed via MindSphere and made available using a MindApp.
Nine company challenges, a maximum of four finalists each time
While Baader’s interest lies in optimizing fish marketing, there will be other teams at work on solutions to different problems in the run-up to the Hannover Messe – for instance solutions for the Expo2020 in Dubai, or ways of optimizing pitch maintenance for FC Bayern. In total, there will be nine companies with totally different fields of interest entering MindSphere Open Space Challenge. Siemens has invited interested software developers and startups to take part in the contest, who will be presenting their creative ideas, concepts and solutions at the show. These will be streamed live for anyone to follow – providing the developers with important exposure to a wider audience. The winner will be picked directly at the show, and will then have the opportunity to implement the MindSphere app for the customer with the support of Siemens.
Faster app development
Many developers will be working with the new version of MindSphere, which offers additional analytical functions, a more efficient development environment with Application Programming Interfaces (APIs) enabling faster app development, and extended connectivity with support for wide-ranging standard interfaces such as OPC UA through to Modbus.
MindSphere Lounge – immersion in the digital world
Visitors to the show will have the chance for full immersion into the digital world in this year’s MindSphere Lounge, where they can try out different apps and talk shop with experts about app development and utilization. Also available in the MindSphere Lounge will be extensive information about MindSphere World. This user organization was launched back in January with the aim of expanding the ecosystem surrounding MindSphere on a global basis and providing support to its 19 members in the development and optimization of IoT solutions based on MindSphere and opening up new markets in the digital economy.
Also featured will be a showcase dedicated to SiDrive IQ, the new digital platform for the evaluation of drive data based on MindSphere. Its aim is to open up a new dimension in data transparency for plant and machine operators over their installed drive systems, enabling digital fleet management and optimized servicing activity. The continuous analysis of data not only saves time but also enhances plant availability, as issues such as potential sources of error can be identified at an early stage and fixed before a problem occurs.
Baader Food Processing Machinery produces machines for the on-board processing of fish on the high seas. Baader machines are the only ones anywhere in the world which allow a catch to be processed while still at sea. The company also produces machines for poultry processing. Baader’s customers include companies of all sizes from across the food processing industry.
In the age of digitalization and the Internet of Things (IoT), an increasing number of machines and systems are being driven by billions of smart devices which produce enormous volumes of data. We have only just begun to leverage the many benefits offered by this data flow. MindSphere is the cloud-based open IoT operating system from Siemens which gives companies the ability to understand their data by linking products, plants, systems and machines to the digital World quickly and securely. MindSphere opens up this wealth of data from across all machines and systems, enabling its transformation into productive business outcomes with the aid of efficient industrial apps and progressive analysis. With MindSphere, Siemens is opening up whole new dimensions in terms of productivity and efficiency for companies of all sizes from every sector of industry.
Baader Food Processing Machinery specializes in machines for fish processing directly at the point of the catch on the high seas.The Open Space Challenge will see external developers working on creative MindSphere-based approaches in open cooperation.

Frost protection using water - Fruit grower protects blueberry harvest with sprinkler system using Siemens technology
Dümmer-Weserland;Germany. The crops grown in the fruit orchards of the Thiermann agricultural business in Dümmer-Weserland include blueberries. To protect the frost-sensitive blossom of the blue fruit from damage in freezing temperatures, Thiermann uses a frost protection sprinkler system controlled by Siemens technology. By protecting the blossom, the fruit grower is able to avoid potential lost harvests worth millions and so ensure a plentiful yield.
Late frosts, unseasonal temperature dips and similar weather phenomena – even when the warmer weather seems to be just around the corner, night frosts can pose a potential threat until well into the spring. A frost at this stage can result in devastating lost harvests for vegetable and fruit growers. The Thiermann agricultural business located in the Dümmer-Weserland region of Germany was confronted with this problem back in 2010 when it lost around 50 percent of its blueberry harvest as a result of frost damage to the sensitive blossom. The business, which not only produces fruit and vegetables but also operates traditional mixed farming and even generates wind power, now protects the buds of the small blue fruit using a system which sprays water over the bushes using sprinklers, so protecting them from the effects of frost. The system is controlled by the Logo! 8 logic module and Simatic S7-1200 from Siemens.
It may sound paradoxical to use water as a way to stave off frost, but this type of frost protection actually makes use of the physical properties of water. The transition from one state of aggregation (liquid) to another (frozen) generates warmth. If water is constantly sprayed onto the bushes when a specific temperature is reached, this process of transition persists and the blossoms will not reach freezing point. “The point at which the sprinklers are activated depends on how far the blossom has progressed,” explains Rainer Plenge, head of blueberry cultivation at Thiermann. Therefore wells were drilled along the edges of the field and control cabinets were installed. The pumps are controlled by the Logo! 8 logic module with a power supply for 24-volt operation. As well as the pressure, the Logo! 8 also monitors the external temperature. If this drops below a previously defined threshold value, it transmits a message to one of the total of four Simatic S7-1200 CPUs (Central Processing Unit) in the head-end station. The Simatic CPUs are engineered using the TIA (Totally Integrated Automation) Portal, and the Logo! 8 programs were developed with the software Logo! Soft Comfort. Operators use a 12-inch Simatic HMI TP1200 Comfort color display to interface with the system. Sirius soft starters limit the starting current to the pumps when they are switched on.
Ideally equipped to beat the frost
17 of the 34 pump stations are linked to the central head-end station using a Scalance M826-2 router over two-wire DSL cables. The remaining stations are linked using an additional Scalance M874 router over the GSM mobile radio network. This ensures a permanent data exchange between Simatic and Logo!. The Scalance S615 Security Module protects the network against unauthorized remote access. The vital importance of the frost protection system for the fruit grower was demonstrated once again in the spring of 2017. “Over 14 nights, the temperature plummeted to the point where we had to use the sprinkler system to protect the bushes,” recalls Plenge. “On some occasions, the plants remained covered in a layer of ice until the early afternoon. Without the sprinkler system in place, we would have sustained losses in the millions.”
Each of the total of 34 pump stations is fitted with a control cabinet which accommodates the control components for the water pumps.
Using a frost protection sprinkler system, fruit grower Thiermann keeps the sensitive blueberry blossoms safe from late frosts.
Alongside the Logo! 8 and Simatic S7-1200 control systems, the Sinema Remote Connect Management Platform is also used to enable convenient remote access to the entire system.

Charlottetown, Canada. In cooperation with Siemens, Canada’s Diversified Metal Engineering (DME) Group has developed customized automation solutions specifically for craft beer breweries. Using a range of scaled automation packages, the brewers are able to improve their productivity and flexibility and ensure consistent product quality even for small batch sizes. The offered solutions are also designed to support breweries on their way towards digitalization and Industrie 4.0. DME produces production equipment for a number of different sectors such as biotechnology, bioenergy and marine applications, but the majority of its business is focused on craft brewers. In this field it is among the world’s leading suppliers.
One of the greatest challenges for DME and Siemens was that most craft beer breweries are small, independent businesses that are not able to command the same financial resources as larger industrial concerns for implementing the automation they need. This meant that the best approach was to develop a flexible, scalable solution that would be affordable for a range of different budgets. One of the benefits of the Siemens-DME alliance – right from the start - was that Siemens offers a wealth of experience in brewery automation, and is also able to provide vital pre-sales and after-sales services, even to small businesses no matter where they are located. At the heart of every solution is a Simatic S7 control system including a Simatic universal controller and a process management system such as Braumat.
Custom solutions to suit any budget
“When we go to visit a new client, we sit down with them and ask: ‘What is your budget, what do you need to accomplish?’ Then we’ll recommend a Siemens package to them, and explain how the system will operate, what data it will control, and just how sophisticated it is,” explains Peter Toombs, President and CEO of DME. Even where the budget is really tight, as he explains, it’s possible to put in place a suitable solution that can grow over time. For instance, adding a new beer tank is a matter of just a few clicks. The pre-programmed solution enables customers to optimally control and improve their brewing processes. A particular benefit is the user-friendly graphic interface. Production data such as temperature and flow can also be exported to Excel and further analyzed to provide the basis for informed production-related decisions. “This technology is the single largest investment, the biggest business decision they (the craft breweries, Ed.) will ever make, and it makes their dreams come true. We spend a lot of time with them and we love it. In a lot of ways, we become like family to each other,” says a delighted Toombs. Using the jointly developed solution from DME and Siemens, brewers can be assured of adherence to quality standards and achieving a trouble-free production process. This means they can concentrate on what they do best: Developing new and improved recipes and marketing their products.
Most craft breweries are small, independent businesses, so the automation solutions developed by the Diversified Metal Engineering (DME) Group from Canada in association with Siemens are tailored to different budgets.
At the heart of every solution is a Simatic S7 control system complete with controller and process control system such as Braumat.
The automation solutions are designed to allow them to be expanded as required: adding a new beer tank for instance takes just a few clicks.
For a perfect brewing result, small breweries are turning to modern process automation to perfect the quality of their handcrafted beers.

Lingen/Erlangen/Munich, Germany. Siemens and Neptune Energy Germany have signed a partnership agreement joining development efforts in the field of digitalization. Neptune is an exploration and production company, part of the globally active Neptune Energy Group, and is an expert in the production of hydrocarbons. The Co-Creation partnership agreement allows both companies to combine their know-how – Neptune with its expertise in the field of oil and gas production and Siemens with its automation, IT and data analysis skills. The objective is to bundle their knowledge and experience with a view to optimizing the capture and evaluation of data in oil and gas extraction in order to increase the productivity and security of extraction facilities.
“New possibilities in the field of digitalization mean we are able to undertake preemptive repairs before an anticipated fault occurs,” says Arno Spies, CEO at Neptune Energy in Germany. “This agreement will provide us with a platform for employees from a range of disciplines to develop joint solutions for the future in order to increase the efficiency and security of operations.” The Co-Creation agreement is all about evaluating both historical and real-time data from the feed pumps in operation as a first step. This data will then be backed with mathematical functions and the resultant image analyzed by experts. Special software detects imminent anomalies and algorithms in the technical systems and recommends action for operating and maintaining the facilities. “We would like to use this approach to look into the future of technical facilities in the future so that we can carry out predictive maintenance, helping to make significant improvements in planning reliability,” explains Stefan Engelshove, Vice-President Oil&Gas at Siemens Deutschland.
Presentation at the Hannover Messe
A vital part of the collaboration is the use of the MindSphere cloud-based, open IoT (Internet of Things) platform from Siemens. MindSphere makes it easier for customers to develop new apps. The focus here is on digital solutions for feed pumps from the oil field in order to collect the data generated by the pumps and then to be able to use it in a meaningful way. “The first results of the collaboration will be presented at the Hannover Messe 2018,” says Bernhard Reichle, Process Industry Sales Director.

Murcia, Spain. Juan José Albarracín (JJA) is among the market leaders in the production and marketing of high-quality spices such as paprika and pepper blends. Founded in 1854, the company is also the oldest of its kind. To future-proof the quality of its products moving forward and to simplify the operation of its plants, JJA relies on extensive solutions from the Siemens product portfolio. These not only help the producer to improve the performance of its milling plants, but also increase plant availability and simplify control of the drives. The Siemens solution also permits simple adjustment to future requirements.
Until the new solutions were introduced, the products were still processed using largely manual processes. This meant that only limited or no use of product data could be made to optimize production sequences, and also made the process of troubleshooting and localizing faults very complicated. The extensive modernization of its operations using Siemens components such as a modern Scada system, a new plant controller as well as converters and motor starters – all engineered in the TIA (Totally Integrated Automation) Portal – has allowed JJA to move its production into line with the latest state of the art.
The Simatic S7-1500 is used as the central controller. The company uses the runtime software WinCC Runtime Professional to operate and observe its processes. Simatic IPC547E hardware is also used to enable simple, intuitive process visualization. JJA also relies on Sinamics G120C built-in units and Sirius 3RW soft starters to control the spice mill drives. Operation and visualization of the overall plant take place using Simatic Industrial Flat Panels with touch functionality. The Siemens solution was rapidly and successfully integrated into the existing infrastructure, and allows simple plant operation coupled with the assurance of high product quality. The production data can now be integrated into the existing ERP (Enterprise Resource Planning) system, improving both traceability and documentation. The selected configuration is additionally designed to permit trouble-free expansion of the plant at a later date. Detailed visualization of the production sequences enables particularly intuitive plant operation, while the simple localization of faults has meant a significant improvement to plant availability.

Top comfort - invisible to the eye: Siemens controls ensure everything runs smoothly behind the scenes in the Hotel Bayerischer Hof
Munich, Germany. The Hotel Bayerischer Hof, one of the most luxurious places to stay in Munich, has extended its capacity recently with the addition of south and north wings. The most up-to-date automation technology from Siemens has been installed behind the scenes – completely invisible to guests. It controls room access as well as room air conditioning and lighting. Unlike the unreliable relays used in the original building previously, the modern Logo! 8 control system provides low-maintenance and therefore very efficient automation.
Siemens Logo! control technology has been used in the Hotel Bayerischer Hof since 1996 – initially in only 20 sample room where the Siemens technology replaced existing relays. Over time, 300 of the 341 rooms were converted. The 29 rooms in the new build are the first to be fitted with Logo! 8. “We wanted one control system which could control as many elements as possible, which is easily and freely programmable and which also takes minimal space in the control cabinet,” explains Horst Erharter, self-employed electrical engineer and in-house ‘technician’ for the hotel. “Logo! 8 combines all these features in one. It was therefore a logical decision to fall back on this control system.”
Logo! 8 controls not only the lighting but also the drapes, radio, room access and room temperature. The KNX building system bus has also been installed in the new wing. “Each control is allocated to a CMK2000 communications module allowing innovative KNX technology switches and dimmers to be integrated into the automation,” explains the electrical engineer. The rooms are also connected to a central unit via the system bus which allows Reception to control the default settings for lighting and temperature. If a fault occurs, this is notified immediately which reduces reaction times significantly. Each communications module allows up to 50 items to be freely managed – leaving plenty of scope for individual parameters. For example, if a guest leaves a room, the control registers the access chip and automatically switches off the lighting. When the guest returns, the control recognizes this as well and switches on only those lights that were on previously. The freely programmable Logo! 8 is a major benefit of the control system. Users can choose from more than 40 preset functions from the Logo! SoftComfort engineering software, such as a weekly timer or on/off delays, and adapt the application to individual requirements. Temperature data can be saved to files and evaluated.
Other projects under starter’s orders
As everyone is so pleased with the control system in the Hotel Bayerischer Hof, the next projects are already being planned. Plans are in place to use Logo! to automate the lighting in the hotel’s Night Club bar as well as the well-established Palais Keller restaurant in the future. Erharter is therefore in close contact with Siemens. “It is extremely important for us to get the customers’ real-life experiences,” explains Josef Ploch, Marketing Manager for Logo!. “Not only does this provide us with feedback on the functionality used in practice, but, at the same time, it gives us information on where we can extend or improve our control system.”
The Bayerischer Hof Hotel uses modern Siemens control technology to automate, for example, room lighting and temperature control.
The most recent generation of the Siemens logic modules Logo! 8 can be found in the hotel new-build, for example, when a guest leaves or enters the room and the light is automatically switched off or on.
Before Logo! was installed, functionality in the rooms was controlled by unreliable relays – with Logo!, automation is not only more reliable but also more versatile.
In addition to room lighting and air-conditioning, the hotel also uses the Siemens logic module, for example, to monitor and control the water temperature in the hotel pool.
The new rooms are individually connected to the central unit via the KNX building system bus.
