Dear Readers,

“The more options to choose from, the harder the choice.” Over 100 million citizens in Norway, Austria, and Germany have been called upon this Fall to determine the course that their country will follow. The agony of choice – the need to weigh all possibilities in order to make the correct decision. This is the everyday life for experts in building technology. Decisions here have effects that may only become apparent years later; therefore, they deserve careful consideration.Our customers have already made their choice: Now you can learn in this issue why, for example, toom Baumarkt home improvement centers, a subsidiary of the REWE Group, chose the WAGO-I/O-SYSTEM 750, and how CO2 emissions in their 360 German stores should be re-duced by around 30% by the end of 2015. The efficient use of energy is also the topic of “Efficiency House Plus”, in which the Federal Min-istry for Transport, Building, and Urban Development examines Best Practice solutions for virtually climate-neutral new construction and ren-ovations. And not least, the standardized design of lighting and blinds control using the WAGO-I/O-SYSTEM 750 provides the foundation for maximum energy efficiency as well as a reduction in investment and operating costs for a pharmaceutical research building.Applications like these clearly reveal that the selection of WAGO components and solutions demonstrates a “good choice” in real life. It is in this sense that I wish you the best of times while reading WAGOdirect building!

Best regards,

Karl-Heinz SandersManager of Market Management Building Automation

■ Flexible, functional, efficient: The WAGO-I/O-SYSTEM guarantees a high level of functionality and flexibility in the lighting and blinds control for a research building used by the pharmaceutical industry. The standardized design of the automated solution reduces both in-vestment and operating costs as well as the time required for planning, assembly, and start up, and – not least – forms the foundation for maximum energy efficiency.

120 colleagues work across numerous disciplines in the 9,000 m² of multi-functional building space; their efforts are highly interconnected as they investigate and develop innovative medications for patients around the world. The pharmaceutical firm is consciously betting on highly automated, innovative solutions to enable safe and flexible building operations that are energy efficient and reduce the consump-tion of finite resources. Therefore, the lighting and blinds controls were conceived from the start with the following functions:

• Each light and each blind can be individually controlled.• Depending on the amount of outside light and the position of the

blinds, the lights are dimmed to minimize energy consumption.

• The blinds are controlled to minimize energy consumption; their movement depends on the position of the sun, the intensity of the outside light, and external temperatures.

• Standard switches are used in all rooms. At all times, the users have the option of using the switch to shut off the automatic con-trol of the lighting and/or blinds for a definable period of time.

• Any function can be locally or globally carried out at a higher level (e.g., time-dependent on/off switching of lights)

All components for the DALI light controls and the blind controls for the SMI drives come from WAGO. The choice was based on good past experiences with products and services delivered by the Minden-based company. In recent years, the pharmaceutical company carried out some joint projects with WAGO, in which a test system was designed to verify the functionality, usability, and system limits for using automated controls for lighting and blinds.

LIGHT AND PROTECTION FROM THE SUN, ON DEMANDThe WAGO-I/O-SYSTEM 750 takes on lighting and blinds control in a research building used by the pharmaceutical industry.

In the new, multifunction building, 120 coworkers contribute to research on innovative medications for patients around the world.

LIGHT AND PROTECTION FROM THE SUN, ON DEMANDThe WAGO-I/O-SYSTEM 750 takes on lighting and blinds control in a research building used by the pharmaceutical industry.

■ Flexibility and economic efficiency through standardizationA total of 13 programmable 750-881 ETHERNET Controllers from WAGO control the lighting and sun protection for the research build-ing. The high-performance controllers, with PLC functionality, manage more than 24,000 data points. They communicate with a system con-trol PC via a CODESYS-OPC server.A high degree of standardization is important to the operator, as it guarantees transparency, limits the costs for maintenance and replace-ment parts, utilizes the repetition effect, and, in particular, uniformly applies only one software program to all controllers. In addition to lowering investment costs, this type of high standardization reduces the time requirements for planning, installation, and start up, as well as operating costs. Therefore, each 750-881 Controller is identically designed: all have a module with 8 outputs and 16 inputs, as well as three DALI and two SMI modules. This means that each PLC can control three times 64 DALI lights, two times 16 SMI blinds, and the assigned switches. Data point specific settings for the controllers are not implemented by changing the software, but instead by changing the parameters.

Each controller can regulate up to 50 rooms in the facility. The param-eter data for DALI and SMI, and also the behavior patterns (rules) for the lights or blinds respectively, are stored for each room. A total of 255 rules is possible.A WAGO 758 Series IPC serves to detect and distribute weather data, such as brightness, wind speed, temperature, and humidity, to all controllers. This PC also calculates the position of the sun and func-tions as a master controller, distributing weather data and solar posi-tion to the 750-881 Controllers. Based on information from the master controller and input values from switches and buttons, the controllers calculate the set values for the lights and blinds.Hermann GmbH & Co. KG, specialists in building automation and climate control technology, developed the algorithms for controlling the lights and blinds as standard modules based on functional pa-rameters. In addition, the WAGO Solution Provider programmed the controllers and brought them online, developed the web-based work-place visualization, and created the floor plan visualization for the building operating system.

A single 758 Series IPC functions as master: it distributes the weather data to the control-lers and calculates solar position to control the blinds.

■ Web-based operating software for usersA web-based operating software was developed for users in labora-tories and offices. This software enables all users to set the lighting and blinds in their space according to their preferences, and to store and call up these set values. In addition, the software displays current energy use for room lighting and the energy savings achieved over a defined period of time. The assignment of users and rooms takes place automatically by importing the master data base for the communica-tion system via the operating system.A floor plan-related operating system was implemented to operate the system. It is also used by maintenance and repair personnel, who can obtain an overview of the entire system, which they then use to carry out interventions as needed. The operating system, which is equipped with the Herrmann’s proprietary “hercon” automation module, takes on central functions, such as automatic on/off switching of lights, and additionally manages the parameter data for all PLCs.

■ ConclusionBy using the highly standardized WAGO-I/O-SYSTEM 750 in con-nection with software for optimizing energy consumption along with a higher level operating system, the system represents an optimal solution for operating lights and blinds. Energy costs and also main-tenance expenses are reduced by the controllers. Adjustments due to changes and building alterations can be easily implemented due to the high flexibility. The users are satisfied and the system is extremely stable.

WINSTA® MINI SPECIAL AND MIDI SPECIAL: LARGEST PORTFOLIO, GREATEST CONVENIENCEWAGO readily meets the growing number of varying circuits within building installations via the industry’s largest pluggable connection system.■ Increasing automation levels, growing expectations or usability, and flexible room configurations require an increasing number of different circuits in modern building technology. This results in an increased number of pluggable connectors with customized pole markings.

The WINSTA® MINI special and MIDI special connector series are a response to the increasing complexity and the growing need for cus-tom building installations. B-coded plugs, sockets, cable assemblies, and distribution connectors are available in three different colors: gray, light green and pink. Each of these three versions is available in 2-, 3- or 4- and 5-pole configurations and can be printed at the factory to suit customer requirements. All coding types for the WINSTA® plug-gable connection system are protected against mismating according to IEC 61535. Within B coding, all special variants are compatible with each other according to IEC 61984; they can be differentiated according to color and pin marking.

WINSTA®, with MINI special and MIDI special, is the industry’s larg-est pluggable connection system for the fast-growing number of differ-ent electrical circuits. WAGO allows customers to meet their specific requirements easily and cost-effectively. WAGO’s solutions can be implemented up to 70% faster, while providing engineers with a cost advantage of approximately 30%.

WIRE AND VERTICAL JUMPERS FOR TOPJOB® S AND X-COM® S MINIVertical and horizontal potential multiplication – via double-deck vertical jumper and push-in type wire jumpers.■ WAGO’s portfolio of jumpers continues to expand: Double-deck vertical jumpers and push-in type wire jumpers join both the TOPJOB® S 2000 Series and X-COM® S MINI 2020 Series. WAGO’s 2000-492 Vertical Jumper vertically commons both levels of a double-deck terminal block. The vertical jumper has a rated volt-age of 500 V and a maximum nominal current of 13.5 A. WAGO’s push-in type wire jumpers provide potential multiplication over several DIN-rail terminal blocks. These jumpers are available in three lengths: 60 mm (2009-402), 110 mm (2009-404) and 250 mm (2009-406). For 0.75 mm² (AWG 18) conductors, the rated voltage is 800 V and the maximum nominal current is 9 A.

WAGO’s TOPJOB® S DIN-rail terminal block range features different jumper systems and provides any commoning possibilities: push-in type jumper bars for the standard connection of different DIN-rail ter-minal blocks, staggered jumpers for commoning different potentials in a single jumper slot, adjacent jumpers for continuous commoning of

one potential in a single jumper slot, step-down jumpers for combining different cross sections, vertical jumpers for the potential multiplica-tion over several levels in a DIN-rail terminal block, wire jumpers for the individual connection of poten-tials with different spacing and heights.

■ A paradise for do-it-yourselfers and crafters: At toom Baumarkt home improvement centers, customers find everything for construction and technology, as well as ambiance and designs. toom Baumarkt garden centers also provide a timely assortment of plants, from indoor plants through balcony pots to outdoor beds. Deal respon-sibly, in the sense of the community, is the company philosophy at toom Baumarkt home improvement centers, a subsidiary of the REWE Group. Within the context of their sustainability strategy, new and existing buildings are being equipped with WAGO’s au-tomation technology. By 2015, the around 360 German stores should have reduced their CO2 emissions per square meter of sales floor by 30% in comparison to 2006.

toom Baumarkt home improvement centers has made a further step in implementing their sustainability campaign with the opening of a new home improvement center in Nieder-Olm in the Rhineland-Palat-inate. This store, completed at the beginning of 2012, is the compa-ny’s first certified Green Building, and was designed so that energy and water are used particularly frugally during daily operations. The store in Nieder-Olm additionally is the first home improvement cen-ter in Germany to fulfil the requirements for the “Silver” certification

AMBITIOUS GOAL: 30 PERCENT LESS CO2 BY 2015Equipped with the WAGO-I/O-SYSTEM 750, the toom Baumarkt home improvement center in Nieder-Olm is the first center in Germany to fulfill the requirements for the “Silver” certification from the DGNB.

offered by the German Sustainable Building Council, the DGNB. “We consciously decided to get certified by the DGNB, because for us it represents the most sensible bridging of ecological and econom-ic qualities,” explains Tobias Müller, the man responsible for energy management for the properties owned by toom Baumarkt home im-provement centers.

■ Ecological and economicMüller is involved in ensuring that the REWE Group subsidiary achieves its ambitious goal: Between 2006 and 2015, the CO2 emissions per square meter of sales floor should be reduced by 30 percent – and in all 360 stores. This can only succeed if heating energy and electricity are used efficiently. In this as well, the REWE Group promotes renew-able energies, in that all toom Baumarkt home improvement centers are supplied exclusively with green electricity. The Green Building in Nieder-Olm already supports the active reduction of greenhouse gas emissions by the additional use of environmentally friendly technolo-gies for obtaining energy as well as construction elements like daylight architecture and efficient insulation.Supplementing all of this was the break through in technology on the automation side. “Up until then, proprietary systems were commonly in-

AMBITIOUS GOAL: 30 PERCENT LESS CO2 BY 2015Equipped with the WAGO-I/O-SYSTEM 750, the toom Baumarkt home improvement center in Nieder-Olm is the first center in Germany to fulfill the requirements for the “Silver” certification from the DGNB.

stalled in our stores, which meant that we were quite dependent on the manufacturer, and there were a lot of them.” According to the engineer, “We’re remedying that at this site with the uniform conversion to the CODESYS programming environment and the WAGO-I/O-SYSTEM.” The sales center in Nieder-Olm stands at just under 9,000 square me-ters, and includes a total of nine 750-880 ETHERNET Controllers from WAGO installed in decentralized control cabinets. The Starnberger firm J&K Lausser Regeltechnik undertook implementation of the work. Data communication was significantly simplified by using a uniform automa-tion system for instrumentation, control, and automation, and for the electrical systems. This made the addition of special interfaces, which are otherwise common, superfluous.

■ Optimal conditions for customers and employeesThe controllers with PLC functionality take over the control and mon-itoring of the entire lighting system, as well as the complex heating and ventilation systems. Ventilation and airing of the building are combined with a heat recovery system. A heat exchanger installed on the roof uses the exhaust air to heat the supply air. In addition, sensors in the ventilation system measure the CO2 content in the interior air. This guarantees that, depending on the number of peo-

ple in the store, an optimal amount of fresh air is always supplied – and at the lowest possible expenditure of energy. Beyond this, the air-tight construction ensures particular frugality. This type of con-struction reduces interior drafts and lowers the losses from the ven-tilation system by around 25%. To ensure that an optimum working environment prevails at the registers at the entrance, the temperature controls for each register can be set by the employee.A 1300 square meter photovoltaic array on the roof provides 189 kW of solar power to the Green Building. However, the sun light is not only used to generate electricity; it is also taken into account by the WAGO controllers for the DALI lighting controls. Twelve large domed skylights, which cover 20 percent of the sales floor space, are distributed across 5500 square meters of the roof. The entire lighting system is controlled by brightness sensors, which makes it both dependent on daylight and energy efficient. Thus, only as much artificial light is generated as it needed at the moment. In addition, each of the 500 DALI lights is individually controllable, such that the store can determine lighting according to individual needs and light scenarios. This saves additional energy – and con-tributes to the welcoming atmosphere for shoppers.

■ Controlling and monitoring the system technologyIn addition to automation tasks, WAGO components take on another de-cisive roll at toom Baumarkt home improvement centers: All relevant data points are transmitted to a higher-level energy management portal. toom Baumarkt home improvement centers thus obtain a centralized overview about use, usage groups, and individual systems statuses. Comprehen-sive, continuous evaluation, optimization, and regulation are the result.This monitoring strategy is a continuation of the automation concept that toom Baumarkt developed with WAGO project marketing. The primary and subordinate meters for all consumers communicate via M-bus. The data detected include the energy used by the shelving, roof, exterior, and garden center lighting, the amount of heat, as well as water and irriga-tion water. Monitoring of system technical parameters like temperatures, ambient air quality, and switching status provides a deeper insight into the technical interplay of the individual sections.

Three PERSPECTO® CP 121 Control Panels with target visualization, which are installed at the information center, in the garden center, and in the manager’s office, provide on site access to the building systems. In addition, all information can be viewed over the Internet via the energy management portal, which runs on a classic Web server, and can be released specifically to third parties – for exam-ple to service technicians. Due to the transparency of the data, which is always available, the entire system can be regulated towards a constant optimum. “The platform independence and openness was quite important to our decision to equip all toom Baumarkt home improvement centers according to this model.” Müller emphasizes, “That is probably not possible on a one-to-one mapping, due to the fact that circumstances are always different between stores; however, we have Nieder-Olm as a flagship project to guide us in achieving our goal of 30% energy savings.”

The sales center in Nieder-Olm stands at just under 9,000 square meters, and includes a total of nine 750-880 ETHERNET Controllers from WAGO installed in decentralized control cabinets.

Everywhere, where things are a bit tricky, where feasibilities need to be examined or individual desires implemented, the project manage-ment at WAGO is available for support. “That was also the concept for our M-bus meter,” Müller remembers, “to enable clear identifica-tion of each meter, we wanted to access the secondary ID instead of the primary ID. The necessary adjustments to the CODESYS func-tion blocks and all affected configurations were quickly implemented. When you are working on outstanding projects like this, it just makes it more fun to work with professional partners.”

MY HOUSE, MY POWER PLANTLife and mobility during the energy transition: WAGO-I/O-SYSTEM delivers the research data.

■ The Federal Ministry for Transportation, Building, and Urban Development uses around 40 single- and multi-family dwellings to test Best Practice Solutions for virtually climate-neutral energy stan-dards in new construction and for renovations. In Berlin, the Feder-al Ministry as the project sponsor went a step further and coupled an “Efficiency House” with electro-mobility. The I/O-SYSTEM 750 from WAGO has two tasks in the house at Fasanen Street 87a: Controlling the complete energy management and recording op-erating data for monitoring.

What kind of things does a family of four experience when they live for a year or longer in a futuristic-seeming house that offers ev-ery technological gadget that is currently on the market? How can the installed systems operate best? And how efficiently do they work? These were the questions that Jörg Welke and Dr. Simone Wichers and their children, Freya and Lenz, had to answer every day. As in all technologically driven research, the concern in Ber-lin was how the technology could be controlled. Consequently, the family was followed by social services during their long-term test. “We wanted to consider the topics of living and residing, commut-ing and traffic over the course of the energy transition,” explains State Secretary Rainer Bomba within the context of a transition to electric vehicles. The German auto industry also wants to test their E-mobility activities. This expansion of autonomous energy gen-eration with maximum self consumption creates new technical prob-lems that extend beyond the otherwise common functional scope of building automation. In Berlin, the WAGO-I/O-SYSTEM 750 is therefore used for the actual building automation through Gira HomeServer. In total, the building in Berlin Charlottenburg has three controllers with three very different tasks.

■ Controlling battery chargingIn addition, a WAGO Compact PLC takes on the complete charging management of lithium-ion batteries in an outdoor enclo-sure. These were previously used in the electric version of the Mini by BMW and at the end of their mobile usage, they are begin-ning a second life as stationary energy stores. Using this buffer, the electricity generated on site can be used for need-based applica-tions in the house as well as for charging the electric vehicles. The WAGO-I/O-SYSTEM 750 takes over turnkey control and moves the battery-supported storage further in the direction of the “virtual power plant”. The research is also supposed to determine whether such systems actually have the ability to improve network quality and to smooth output fluctuations.

Page 14: direct building - Wago


“We proceed in all of our individual projects completely inde-pendent of producers. That is the only way that we can deter-mine which technologies truly work best and for which reasons,” says Hegner. The same applies to handling. If, for example, a system provides information about photovoltaic electrical pro-duction from the previous day in an easily accessible format, then this promotes general acceptance of the technologies used. Living in an energy-efficient manner should not also mean doing without.

■ Controlling the energy managementA second control strand implemented using WAGO components serves complete energy management in the building. In this case, the controller tracked data points to determine how energy flows can be controlled to adjust based on weather predictions. For example, is the electricity generated by the photovoltaic system used to charge the vehicles? stored in the buffer? used to run the washing machine? supplied directly to the Berlin electrical grid? When does it make more sense to consume the self-generated power directly, and when should the inexpensive power from times of excess energy production be used as a temporary off-set for charging? The intelligent processes used are so adaptively designed that they can autonomously adjust to the conditions de-scribed in brief, as well as to changed usage behavior on the part of the residents. The Federal Ministry has linked the building with researchers and the public using the third control line. This is the point where the I/O-System 750 can display its transparency in terms of inter-faces. Temperature, humidity, room- and device-related energy consumption are all tracked: 750 data points are installed in the home. This also detects social data – for example, the use of hot water during showers, cooking times, use of lighting, television viewing, and vehicle activities.

■ Making data availableIn order to make the collected data constantly available to the around ten associated research projects, the I/O system for-wards the data directly to the central history server via Modbus TCP. In addition, the WAGO solution functions as the interface with the Gira HomeServer. The task here is to detect KNX com-munication and transmit it to the GLT via ETHERNET so that this data is also available for monitoring, analysis, and optimization over the internet.The measurement configurations are designed so that monthly en-ergy balances can be generated as well as single performance evaluations of the system technologies used. In addition, air tem-perature and CO2 concentrations in all rooms is constantly mea-sured. The usable and excess production from the photovoltaic system, as well as consumption by all devices in the house is con-stantly displayed.

■ Applicable across GermanyFrom the microcosm of the Fasanen Street in Berlin to the Feder-al German macro level: the Federal Ministry currently has more than 30 additional houses with comparable research focal points in the electrical grid. According to information from Hans-Diet-er Hegner, Head of the Division of Civil Engineering, Building Research, Sustainable Construction at the Federal Ministry of Transport, Building, and Urban Development in Berlin, research-ers throughout Germany are following two major issues: Which technologies deliver, and which also retain the highest energy production? How should the house from tomorrow be operated by its residents so that it is both a comfortable living space and it is truly fun to use the technology?

The WAGO-I/O-SYSTEM 750 assumes complete charging management in the control cabinet.

The WAGO-I/O-SYSTEM 750 also functions as the in-terface for research in the building. Around 750 data points provide information about consumption behav-ior and energy efficiency.

ONE-STOP DALIComplete Solutions and Guaranteed Compatibility: DALI Multisensors for the DALI-Multi-Master I/O Module ■ WAGO has added multi-sensors for the 753-647 Multi-Master I/O Module to its DALI product range in order to detect movement and brightness. The sensors are available in two versions: The first has a connection directly integrated into the DALI bus for mounting as well as for installation on ceilings and in recessed boxes. The second is a multi-sensor kit, consisting of a ceiling sensor, installation set, and a sensor coupler that functions as an interface with the DALI network.The new presence and brightness sensors enable WAGO to offer one-stop shopping for its automation levels in the field of universal DALI lighting solutions. This user can therefore be certain that the com-ponents used will have unlimited compatibility with each other. This is in addition to the user-friendly configuration of the entire DALI net-work, which WAGO provides with the DALI Configurator graphical user interface.

■ Multi-Master Module with power supplyIn addition to controlling 64 DALI actuators, the 753-647 DALI Multi-Master I/O Module supports the connection of up to 16 multi-sensors. This eliminates the need for installing a sensor-only par-allel bus. Reduced installation time and clearer network structure help increase DALI operational efficiency.A 12 mm-wide 750 Series module provides 200 mA power supply to each DALI module. Generally, a single controller operates several DALI modules within a project. WAGO has developed a cost-effective solution for this: An external 230 V DIN 35-rail mounted power supply (787-1007) provides an output current of 1100 mA. Up to five mod-ules can be supplied in parallel in its full configuration.

■ Optimal configurationThe DALI Configurator graphic parameter interface expedites and simplifies commissioning and management of DALI networks. The software’s most prominent features are a simplified project overview, optimized device addressing, efficient batch processing and compre-hensive functions for data backup and restoring (backup & restore). In addition, an “easy mode” can control the most varying switching and dimming functions and light scenes within the network solely through control of digital data points — for devices and groups alike. This en-ables DALI lights to be controlled without any complex programming.

The integrated sensor coupler: The multi-sensor is suitable for mounting as well as for installation on ceil-ings and in recessed boxes.

Multi-sensor kit: sensor coupler, multi-sensor, and installation kit with protection against electrical shock for ceiling installation.

■ The “House of Industry” in Copenhagen was expanded and com-pletely renovated at the end of May 2013. In addition to the Dansk Industri professional organization, diverse businesses, an external conference center, a conference room with seating for 400, and an atrium are housed in the building, which covers eight floors and a total of 40,000 m². Trine Rasmussen and Jesper Poulsen were on site and spent a day visiting the construction site.

The harlequin pattern on the exterior façade dovetails perfectly with its neighborhood, especially Copenhagen’s Tivoli Park and its long-standing tradition of pantomime. A glass-roofed atrium with so-lar panels has been added to the interior. From here, as well as from the conference room and the dining facility, which leads out to the roof terrace, one has a marvelous view of Tivoli Park and the Town Hall square – as well as a particular incidence of light.Pihl & Søn A/S was entrusted with the turnkey construction; Kemp & Lauritzen were responsible for all of the work in connection with lighting, work stations, installation channels and ventilation controls. On a gray and rainy January day, we visited the construction site for the “House of Industry” and met with experts from Kemp & Lauritzen.

■ The Big PictureWe logged a first intermediate stop with Johnny Hansen, the super-visor for all Kemp and Lauritzen electricians at the site. His work space is full of electrical drawings; however, Johnny very obviously maintains a clear overview, not only across his desk but also – as we would see later – about his entire area of responsibility and the people on the entire construction site.

All 1100 cooling flaps were installed with gray WINSTA® plugs that were delivered with the designation “3-2-1”.

Installation using WINSTA® is around eight times faster than traditional installation.

It is possible to assemble a new work station using WINSTA® in less than five minutes.

Junction box connectors from WAGO ensure increased security, fast installation time, and space-saving design.

Johnny led us up to where offices for project employees and admin-istrative personnel are located. Here we met Kenneth Lindegaard Larsen, who has worked as a project assistant for Kemp & Lauritzen at the “House of Industry” since summer 2011. In addition, we met Jonas, who had just completed his training as an electrician and at the moment was interning at Kemp & Lauritzen. We looked at the large main schedule, of which Kenneth said that 60% of the electri-cal work had already been finished and only installation channels, work stations, lighting installations, and the final testing remained. The deadline for many parts of the construction is summer 2012, the rest will follow.

■ Tour of the construction siteJohnny Hansen is responsible for planning and coordination of all work for all of the electricians and thus maintains a clear overview of who is doing what, where, and when. Today, his role was more that of coordinator and electrician. Later, over the course of the tour, we saw him in action at the construction site: he installed a missing cover in no time at all. He has worked for Kemp & Lauritzen for 31 years, and has been the coordinator for other large projects.20 electricians as well as IT and security staff work at the site, so that a total of 30 employees from Kemp & Lauritzen are involved at the “House of Industry”. Kemp & Lauritzen has been entrusted with all of the technical work, with the exception of access controls and ventilation.Sometime later, talk turns to WAGO’s push-wire connectors for junc-tion boxes, which are used to a high degree and are quite clearly preferred by Johnny Hansen and his people in comparison to tra-ditional screw connections. In Johnny’s opinion, the push-wire con-nectors offer many advantages, including increased security, fast installation time, and space-saving design.

■ Installation using WINSTA® is about eight times fasterIn the building interior, we are met by the scent of paint, drilling noises, music carried over loudspeakers, a painter here, and an electrician there. In projects like the “House of Industry”, it is always important to maintain the time schedule. This is merely one reason why Kemp & Lauritzen decided to use the WINSTA® pluggable con-nection system from WAGO.

If you compare installation times of lights installed using WINSTA® with traditional installation, work using WINSTA® is carried out around eight times faster. The electrician can simultaneously avoid incorrect assembly and loose connections, which is especially import-ant for DALI lighting.

WINSTA® plugs in 5-pole configuration for dimmable lights that are awaiting their connections: In all, around 4000 lights are connected using WINSTA® in the “House of Industry”.

In addition to lighting, Kemp & Lauritzen decided to use WINSTA® in the cable ducts. The power supply to the computers uses white cables and the usual 230 V supply is indicated by black WINSTA® cables. By this means, not only is the implementation fast, easy, and safe, but also during later maintenance or renovation, it will be easy to identify which cables are used for which purposes. For example, a new work station can be assembled in less than five minutes.

■ Experience with WINSTA®

Johnny Hansen is extremely experienced with the use of pluggable connectors in real world applications. He has worked with them on projects for Novozymes and Ernst & Young, totaling more than 100,000 m², and has only positive comments – in contrast to tra-ditional installations, which, according to him, are uneconomical on larger projects. “Some of the advantages of WINSTA® are in the better work posture for electricians and in the pre-assembled cables,” Johnny explains.

The office spaces in the “House of Industry” were flexibly configured so that rooms can be reconfigured, expanded, or relocated. For this reason, the technical installations were configured so that a wall can be inserted every 1.6  m. The flexibility offered by WINSTA® is optimal for this kind of in-stallation. An important factor for the building owner was that maintenance and servicing have to be accomplished quick-ly and easily, for which reasons they decided to use WINSTA®

for the cooling flaps as well. All 1100 cooling flaps were in-stalled with gray WINSTA® plugs that were delivered with the designation “3-2-1”.Our visit to the construction site eventually ended. We left the “House of Industry” with a lot of exciting impressions and a huge thanks to Johnny Hansen, Kenneth Lindegaard Larsen, and Jonas.

■ WAGO’s system distribution boxes form the core of the building technology that was installed when the New City Hall was renovat-ed. This automation technology, with BACnet controllers, offers flexi-bility, openness, and interoperability; consideration of a future city-wide facility management network also tipped the scales towards WAGO components.

No other city in Germany is linked so closely with jewelry and fine watch making as the golden city of Pforzheim. The New City Hall of this internationally renowned “jewelry metropolis” underwent compre-hensive renovation measures that began at the end of 2011 and should be finished by the end of 2015.Within the context of this plan, the entire electrical infrastructure of the building was upgraded. Three companies from Pforzheim were involved: Design and solicitation of bids for the fire protection up-grade were assigned to the consulting office for electrical engineer-ing, Volker Wörtz. Eckert Elektro is responsible for installing the elec-trical systems. The complete building automation is delivered and installed by ib company.ib company specializes in network installations across property lines. The WAGO Solution Provider was therefore additionally tasked by the city to develop a plan for a city-wide facility management network. Pforzheim administers more than 250 properties with different build-ing services systems. The problem: Many of these buildings use propri-etary automation systems – which include associated dependencies on the manufacturers. The goal: A simplification of the field, automa-tion, and control levels as well as interoperability of the systems. “In order to avoid limiting competition, we decided against a propri-etary system,” explains Rainer Störzenecker, Building Administer for the City of Pforzheim.

■ Experience and flexibility are decisiveThe renovation work in the city council building took place in sever-al stages. Jan Kühner from the Wörtz planning office is responsible for construction management on site. He describes the approach thusly: “The offices within each section to be renovated were relo-cated into other spaces within City Hall. After renovations of that area were completed, they moved back to their old locations.”The modular and fieldbus-independent WAGO-I/O-SYSTEM 750 forms the foundation of this new building automation technology. “WAGO has different types of controllers in their product portfolio, including those for BACnet, and also offered a good price-perfor-mance ratio. The systems can be easily expanded due to the modu-lar design of the hardware. The decisive point, however, was the long-term experience that WAGO has in building automation and the high interface flexibility of their products,” explains Matthias Zeh, CEO of ib company.

Two standard versions of system distribution boxes were defined for the New City Hall. The standardization was implemented to enable fast replacement of a distributor during a service call. Both Type 1 and Type 2 are equipped with a BACnet controller as well as DALI and EnOcean I/O modules. The Type 1 distributors also monitor and control temperature. The WAGO controllers also transmit error messages, provide data from electrical and water meters, and forward this data to the building control system.WAGO delivered 27 Type 1 system distribution boxes and eight Type 2 boxes, all connector-ready. WAGO’s WINSTA® pluggable connection system guarantees a fast and error free connection. WINSTA® is ideally suited to building system requirements. It pro-vides the ability to simply and safely plug electrical installations and components together. After the renovations are complete, the 35 controllers will administer around 10,000 data points.

COMPLETELY OPEN FOR NETWORKINGIts worth in gold: In Pforzheim, the New City Hall and a city-wide facility network communicate using the WAGO-I/O-SYSTEM 750.

The WAGO-I/O-SYSTEM 750 of-fers the City of Pforzheim the neces-sary openness for interfaces.

■ Decentralized structureThe system distribution boxes, which each administer six to eight office spaces, are located above the ceiling panels in the hallways. “The hall-way lighting is controlled by presence detection. If it is still too low, then additional light can be manually controlled using local switches,” ex-plains Andreas Mürle. Mürle, a systems integration and programming specialist from ib company, executed the building automation in the New City Hall.A ceiling multi-sensor located on each office ceiling is controlled by DALI. The WAGO controllers continuously detect brightness values and pres-ence. Upon entering the room, the lighting can be switched on using an EnOcean switch and the brightness can be adjusted. The constant light control continuously regulates light at the work space. If no presence is detected, then the lighting system shuts itself off autonomously. Heating control is also realized using EnOcean. A corresponding controller is lo-cated in each room to measure temperature. Set point adjustments can also be carried out here. The WAGO controller regulates the heating vents.The BACnet controllers communicate via BACnet/IP through an ETHERNET network with the building control system. The City of Pfor-zheim uses this protocol as a basis to guarantee the desired interopera-bility and to end the tiresome discussion about interfaces.

■ Comprehensive network plannedThe New City Hall, together with four other buildings, forms a pilot proj-ect for a facility management network that will run until the end of 2014. BACnet/IP forms the basis for communications. ib company designed the concept. Over the long term, all city properties will be networked togeth-er. The specifications include non-proprietary solutions for building auto-mation, which must offer the greatest possible openness with respect to economical operation and maintenance costs. Matthias Zeh explains, “At the automation level, WAGO provides all interfaces to the subsys-tems at the field level and to the control level.”ib company is currently implementing a comparable network at a large bank in Baden-Württemberg that will cover the entire location. “This test case shows that the entire thing is feasible. And we’re also using WAGO technology here,” explains the CEO of ib company.

ONE BUILDING, ONE LANGUAGEThe new BACnet controller (750-831) from WAGO simplifies system integra-tion into building automation.

■ There is a multitude of different protocols in technical building au-tomation. In large projects in particular, the individual building sec-tions often develop parallel and independent of each other. This then usually leads to an impenetrable, difficult to maintain jungle of differ-ing communication technologies. The new 750-831 BACnet Control-ler from WAGO is an intelligent, holistic solution for the smooth inte-gration of technological islands with different protocols, like LON or DALI, into one system This helps reduce building automation com-plexity, along with the effort and costs involved for installation and maintenance.

The integrated automation of buildings involves many factors – from appropriate lighting control using weather dependent sun protection to sophisticated heating, ventilation, and air conditioning systems (HVAC). To promote comprehensive communication between the in-dividual sections, a standardized protocol is preferably used as the backbone in modern building automation. This kind of backbone can then be applied to every floor in the entire building. The goal is to introduce a uniform language – from the control systems to the automation levels. This simplifies things for all involved – from instal-lation through maintenance to retrofitting – and is particularly true for complex systems. The BACnet controller from WAGO, which is freely programmable according to IEC 61131-3, provides an effi-cient and flexible solution for all applications. It corresponds with the device type “BACnet Building Controller (B-BC)” defined in the BACnet standard along with the associated defined BIBBs (BACnet Interoperability Building Blocks).

The new 750-831 BACnet Controller from WAGO sim-plifies system integration in building automation, so that expenses and costs for installation and maintenance are reduced.

Page 24: direct building - Wago


■ Total flexibility due to modular designThe WAGO BACnet controller combines the advantages of the prov-en, finely modular WAGO-I/O-SYSTEM 750 with the DIN EN ISO 16484-5 standardized BACnet communications protocol. The I/O system’s modularity enables the connection of virtually any combina-tion of digital/analog inputs and outputs, as well as complex sub-I/O modules, to one fieldbus controller. If a project requires decen-tralized, bus-enabled sensors and actuators from varying technologies, the system can serve as a multifunctional interface. It supports interfaces such as DALI, MP-Bus, KNX/TP1, M-Bus, En-Ocean, SMI, LON, and serial protocols. In combination with the controller, a complete BACnet integration and interoperability with third-party components is thus guaranteed.

■ Efficient and user friendlyThe 750-831 BACnet Controller is based on proven earlier ver-sions, but, like all of the new generation of WAGO ETHERNET con-trollers, now includes a more powerful processor. The available program memory is twice as large, while data storage was in-creased four-fold. At the same time, this controller supports SD card functionality, meaning that data such as the “Trend Log” object can be externally archived. In addition, there is more space available for Web visualization due to the SD card, background images and building ground plans can be stored, and processes can be graph-ically displayed. An ETHERNET line topology can also be set up using the 2-port switch integrated into the controller.The so-called “native” operation of the BACnet controller is particu-larly practical. This means that the user simply plugs in digital and analog I/O modules into the device, the controller scans the I/O module and then automatically generates appropriate BACnet ob-jects for the digital and analog hardware data points. The result: The controller is immediately ready for operation once an IP ad-dress has been assigned, which takes place easily using an integrat-ed DIP switch. This feature reduces the configuration effort required, which can be considerable for complex systems. Additional BACnet objects can be easily created using the BACnet Configurator, or the WAGO-I/O-PRO Software 2.3 with CODESYS, which is based on the IEC 61131-3 Standard. The BACnet Configurator is a user-friendly tool for starting up and operating the controller. It enables use of BACnet services like “Backup & Restore”, “Reset”, or “Time synchronization”. WAGO’s configurator software now additionally provides a helpful Device Manager, which truly simplifies the user’s effort in complex, hetero-geneous BACnet networks. The Device Manager offers the ability to display all WAGO BACnet controllers in table form as an overview, to export this (as CSV files), to process the data points, and to up-load the files again. In addition, the properties of BACnet objects can be queried and changed via a value browser.

The user-friendly WAGO BACnet Configurator has a helpful Device Manager to support users during startup and operation of the controller.

With the aid of the flexible 750-831 BACnet Controller from WAGO, the most varied communication proto-cols, like LON or DALI, can be easily integrated into one system.

The most varied protocols can be integrat-ed into one system using WAGO’s BACnet Controller.

In “native” operation, the BACnet Con-troller is immediately ready for operation once an IP address has been assigned.

The BACnet Configurator provides maximum support during startup and operation.

■ It depends on the right moduleThe integrative building automation design from WAGO, based on the BACnet controller and the WAGO-I/O-SYSTEM 750 would not be complete without appropriate I/O modules. WAGO’s new 753-648 I/O Module connects LON field devices to the WAGO-I/O-SYSTEM 750 with more flexibility and greater independence from suppliers. For the first time, all WAGO controllers can communicate using LON. By using the new module, interfaces at the field and automation levels can addi-tionally be configured to other protocols, like KNX IP and Modbus TPC, just as easily as for DALI or SMI. The new 753-647 DALI Multi-Master Module not only controls 64 DALI actuators, but also connects to up to 16 multisensors. This elimi-nates the need for installing a sensor-only parallel bus. This saves time and money. Commissioning and management of the DALI networks has also been markedly simplified by the DALI configurator.

■ Libraries simplify startup WAGO facilitates work for system integrators by providing compre-hensive libraries for starting up I/O modules. Programmers have to create comprehensive software programs for controlling and visualiz-ing, in particular for executing complex systems, for example in the HVAC area. In cases like this, WAGO goes the extra distance in cus-tomer support by providing completely programmed program macros. These macros enable the definition of individual standards, which are then applicable to a multitude of systems. Thus, the system macros also contribute to cost reductions.

■ Conclusion: One controller for all applications Using the WAGO 750-831 BACnet Controller, the most varied proto-cols can be easily integrated into one system, which simplifies commu-nication between different manufacturer’s products. The user profits due to reduced complexity and easier installation and maintenance of the building automation systems. The BACnet standard can be used for room automation as well as HVAC due to the multitude of I/O modules supported. WAGO thereby supports all essential objects that are important in the HVAC area. With this broad product range of automation components, WAGO delivers a complete solution that is up to the complex demands of system integration in modern building automation, and offers new possibilities for cost reductions.

■ The manufacturer-independent lighting connection system Linect® has become an established standard in the lighting sector in the past few years. There is a reason for this: Linect® has numerous advantag-es that simultaneously convince planners, architects, lighting manu-facturers, and electricians. Since unnecessary adaptation times caused by different plug connections systems are gone, the delivery time required for lights has been shortened. Lighting installation takes place quickly, safely, and without errors. There are no compatibility problems with conventional systems: Electricians have the option to conventionally wire Linect® lights directly to the lighting connection module, or to use plug connection systems, like WINSTA® from WAGO.

Lights with Linect® interfaces are manufacturer independent and can be connected to Linect® connectors for the respective connector sys-tem. Numerous prestigious lighting manufacturers have joined the open standard and offer corresponding products. Lights with Linect® connections enable conventional power supply connection and also connection via plug-in connectors. The great advantage of the uni-form system is the reduction in complexity in individual connection variants. All involved profit from this – from the lighting manufactur-ers through the project planners to those involved in installation.

■ Freedom in planningFor designers and architects, the advantages of the system appear primarily in the compatibility of all components, in particular due to the increased freedom in design and safety in the project. Connec-tion technologies and lighting selection are no long dependent on each other. Tenders for Linect® lighting fixtures can be made both for conventional systems and for connection to various connector sys-tems regardless of the manufacturer. The open source and high com-patibility of the system provide greater planning security to lighting projects, since future modifications or upgrades can be easily imple-mented. Using Linect®, innovative designers have found lighting tech-nology that they can rely on now and in the future.

■ Fewer lighting variantsThe increasing number of manufacturers who offer Linect® lights demonstrates that even the lighting industry find numerous advantag-es in the universal connection system. Linect® reduces the multitude of connection variants for lights that have existed up until now and re-places them with a uniform standard. As a whole, this leads to an increase in efficiency in lighting manufacturing: delivery is improved, sales, production planning, and manufacturing are simplified, and inventory carrying costs are lowered. Designers and architects now select lights according to design, the type of lighting means, and the type of light distribution.


■ Flexible connection possibilitiesLinect® lights can be installed in the following three ways:

1. Conventional wiring to the light connection module: In convention-al installation, the lights are directly wired in the conventional way to light connection modules. WAGO’s Linect® 294 Series offers decisive advantages for this case.

2. Conventional installation using pluggable lighting connection: The lights are simply plugged into the finished installation via Linect® connection modules so that opening the light fixture is no longer necessary. The Linect® plug connector for conventional external wiring is suitable for this application. This connection module is also advantageous for uses in e.g. Scandinavia, where lights with Schuko connection lines are required.

3. Pluggable electrical installations with pluggable connectors: The lights are simply plugged into the finished installation via Linect®

T-connector so that opening the light fixture is no longer neces-sary. The light is immediately ready for use due to plug and play. Linect® T-connectors from the WINSTA® MIDI family are an opti-mum solution for this type of installation.

■ Pluggable connectors for every applicationBasically, pluggable connectors from different manufacturers can be used. WAGO offers a particularly broad product selection and high quality with its WINSTA® family of pluggable connectors. The prod-uct portfolio includes WINSTA® Linect® T-connectors for the follow-ing applications: mains replacement (L‘/N‘), mains (L/PE/N), emer-gency lighting (N/PE/2/L/1/L‘), three-phase current (N/PE/L1/L2/L3), dimming (N/PE/L) DA-/DA+) and mains replacement (N/PE/L/N‘/L‘).

Conventional instal-lation using pluggable lighting connectors: The lights are simply plugged in via Linect® connection modules so that opening the light fixture is no longer required.

THE MODERN ART OF LIGHT INSTALLATIONS ■ Fast installation and high safety

The Linect® T-connectors of the WINSTA® MIDI family enable fast and error-free installation using pre-assembled, quality-checked components and mechanically coded plugs and sockets for differ-ent functionalities like mains, dimming, and emergency lighting. Since the components are protected against accidental contact, Linect® lights can be replaced while the wires are live. Plug-and-play handling guarantees the shortest installation times.

■ Modern lights need modern, pluggable connectionsNever before were pluggable lighting installations in buildings eas-ier, faster, or safer than now with the uniform, manufacturer-indepen-dent Linect® interface. When combined with WAGO’s WINSTA®

pluggable connectors, this presents an optimum solution for build-

ing installations, from which lighting manufacturers, designers, and electricians all profit equally.
