Welcome, ladies and gentlemen, to the presentation on building technology from WAGO Kontakttechnik at the digital Hannover Messe 2021. My name is Daniel Wehmeyer and I am Head of Marketing Management Building Technology at WAGO at our headquarters in Minden. It goes without saying that I would much prefer to be meeting you in-person at a booth and having the opportunity to exchange ideas with you personally. Nevertheless, I am very happy to welcome you here today, that we can look together at a really exciting topic: managing buildings and distributed properties. Programmable controllers, just configuration instead of programming with room automation, with flexROOM®, Energy Data Management, Lighting Management: All of these are topics with a comprehensive range of solutions at WAGO. Maybe you already know this from our booths at other trade shows or in practical use from your own project. The simplicity you expect from us we have now carried over to the topic of managing of buildings and distributed properties. And today, we would like to give you insight into future developments at WAGO in the area of building automation. Managing buildings and distributed properties is a topic that ties in with established innovations, but is still a logical next step towards a holistic solution from WAGO and also takes the area of primary systems into account. But what are distributed properties anyway? What are the challenges in managing buildings and distributed properties? How do I master the data that my building services systems provide and how do I keep track of it at any time, from any location? ? To start, I would like to have a discussion with Stephan Rothermel. At WAGO, Stephan Rothermel primarily works in the area of retail solutions and is the perfect contact person for distributed properties. We'll then continue with the question: “How can WAGO specifically help me with the challenges of managing buildings and distributed properties?” I would also like to give you a little insight into this topic and then we'll take a look directly at the WAGO solutions we have to meet the challenges of managing buildings and distributed properties. We'll take a direct look at the application interfaces and show you a simple configuration to help you achieve your goal. But now I'm looking forward to an exciting discussion with Stephan Rothermel on the topic of distributed properties and the management of buildings and distributed properties. Yes, hello Stephan, I am pleased that I can welcome you here today and that we can once again talk about managing buildings and distributed properties. I've already said a little something about you, but maybe not enough. so, just maybe you can introduce yourself? What exactly is your role at WAGO, Stephan? Yes, hello Daniel. I am also happy to be here. At WAGO, I look after our customers from the retail industry and together we develop solutions for that market. We use the WAGO control system here and try to develop integrated solutions, including solutions that are used across disciplines. We also consider things like energy management, which is also directly integrated. Yes, that's what I do at WAGO. And basically, the most important thing is that we achieve a high degree of automation and that costs are manageable. Okay, so costs – customer investments - that is certainly an important topic. We certainly have that in many places. But what are the other specific points that are, I would say, particularly important in your view with regard to planning such properties? Daniel, regarding the conceptual design, we make sure that we come up with simple, independent and reusable approaches. This is important for my customers because we are rolling out in large numbers, because we work with various installation companies and also have a wide variety of branch offices or stores and work in various locations around the world. WAGO now has a whole team of specialists who are very familiar with the requirements of retail and can implement the requirements of modern properties. Okay, our topic for today is “Managing buildings and distributed properties”. So the question again, when I hear the term “distributed properties”, are distributed properties for you now the branch network of your customers? Well, from my perspective, that's how it is for the time being, but of course there are properties in all areas. It could, for example, also be the campus of a university or it could also be the buildings at a hospital complex – these are all real properties. Okay, so I think I get that. But if you now say that these are distributed properties, then you might already say that the topic of distributed properties is becoming more important. Definitely, Daniel! Just think of the bakery or the bakery shop around the corner. Where in the past a small shop was basically enough, where the bakery was right in the back, most bakeries now operate umpteen stores. That's right. What is the reason for this, in your opinion? That we see it that way now? Clearly, our economy is built for growth, Daniel, and it's diligently expanding. And several hundred shops are no longer uncommon for large bakeries. And we are familiar with this, for example, from the food retail market. the corner shop that we used to appreciate so much has now been completely replaced by the large discount grocery stores or merchants. That's right. so the mom and pop shop is perhaps not that common anymore – that's a shame somehow. I think you're right. But the whole or this development also has its advantages. And we as consumers, including you and I, encourage this. We like to shop in familiar surroundings. It's comfortable when you go into a store and know where everything is and what to expect in the store. This is important for us as humans and since the chain stores are expanding their property network worldwide, we can now even do this on vacation. I don't know whether you have had the same experience at a vacation resort before everything just as it always is, but on vacation! And there are perhaps more chains of this type than you think. And I think you can think of some good examples too, Daniel. Yes, even when I think of vacations and chains too. In this situation, I'm already thinking of one. There are drug stores, textile retail now comes to mind, or pet stores. Of course, those are all good examples and I'm already thinking of others. Yes, or the beverage market, home improvement stores, electronics stores, furniture stores, the entire fast food industry, but also in the service sector. Just think of hotel chains, the fitness industry, motor vehicles, repairs, maintenance and, last but not least, our network of gas stations. Maybe you had to fill up this morning too. So you should also think about that! Filling up – in part electric. But of course, you're right. If you think about it, they are all somehow operators of distributed properties. So we come across the topic every day. Definitely everywhere and we haven't even talked about the largest property operators – that would be municipalities. And if you think of educational facilities, administration buildings, cultural facilities, sports facilities, fire departments, hospitals and more! Okay, that's clear. I know where you're going. And I think I got it, Stephan. Well, and only mentioned in passing: WAGO is also a property operator. Think about how many properties and buildings WAGO maintains. We're directly involved in it all. And I just think it's unmistakable that this issue affects us all and has been very important in the past; but I think that it will also become much, much more important in the future. Okay, now we have the market that we were talking about. When you look at this market now: What do you think? What are the daily requirements? Or what are the requirements for construction and operation of such building automation systems in this market? What are the specific requirements when you look closely at this market? So the biggest requirement or challenge is actually the huge amounts of data that we can capture with modern automation technology to keep track of things. In recent years, we have really tried to record every measured value and every data point with extremely short cycle times and to pump them into databases. And yes, as the saying goes, “We used a sledgehammer to crack a nut,” because in practice, we now actually find it very, very difficult to deal with this amount of data and to use it effectively. Ergo: The whole thing means enormous costs and doesn't really help us. And such technologies, you know that yourself, you then quickly end up on the sidelines. We urgently need to think about how to move forward. Yes, of course you're right about that. So when I think back to my active time in the project business in building automation, that's actually how it is. But the question has changed for me in the meantime. Since I was in the project business a few years ago, has anything changed? Has something become more specific? So I do think that a rethink has started. We reduce the amount of data. We are already starting in the planning phases when selecting data so that we really reduce the amount of data. There are also many technical approaches that reduce the amount of data. So today we also have the option of handling data locally on compact, high-performance controllers and, in principle, only collecting the most important data points in a concentrated manner at a central location. These are things that we do. And once I can managed the core data centrally, I can use it for analysis. And in the case of services, for example, everything can be viewed directly on the controller. Okay, now we've talked about planning and operations. There is another important phase that now comes to mind. How do you see it – if we now see the whole thing in connection with commissioning, specifically commissioning systems? So when it comes to commissioning, first and foremost, you know for yourself from your project time about saving time. So this is important first. To save time and still deliver consistent quality. That means for commissioning, it has to be as simple as possible. They have to be standardized – repeatable. Ideally, you have to check yourself and yes, the larger the number of properties, the more important these properties are. I could also imagine that, especially when I have so many distributed properties, a feature like backup and restore of the entire configuration could somehow be an important topic. How exactly does it look with you there now? Yes, a very important point, Daniel. With the growing number of properties in particular, I have to create opportunities for this and automated backup of data points is important ideally in a cloud environment And from the cloud, for example, i can also restore data or repair parts of the system. Without mechanisms of this kind, properties can actually no longer be operated sensibly. Okay. But now we're talking about a lot of locations. We're talking about the cloud. You said that such features could be included. If I now imagine that I really have a lot of distributed properties, what about security and safeguarding of such systems? I am thinking specifically of the whole topic of networks and cyber security, network security. So security is one of my main topics. I have to be very clear that it is also becoming more and more important in day-to-day activities. Let me say automation networks and IT networks are now par in terms of requirements – that is, they are identical. The mechanisms that we put in an IT network today, that is to say, to be able to close security gaps during operation, and that we have recognized, are simply state of the art. And supermarkets, for example, food suppliers are clearly one of the critical infrastructures, so they fall under the KRITIS regulation. And yes, your supermarket around the corner is also part of that. Yeah, okay, that's an interesting topic. So my supermarket around the corner is now a retail store It's what you do too. If I now say very specifically, let's stick with this retail idea, with the retail business itself, which is above all operators of distributed properties, what is the specific requirement for this special business in operating distributed properties? In general, the following applies to retail: the slimmer and simpler, the better! Okay. Basic rules, yes, Basic rules, yes, so the subject of “simple” is simply shaped in the retail world by a discount family. Let's consider the controller in stores: It also has to be universal. That means using it for different areas, both in the hardware and in the application. It must be manageable by everyone at all times and should also be implementable and accessible worldwide in maintenance, service and commissioning. And the most important thing is that every technician who works on it can, in principle, work with the system without extensive training. That sounds totally understandable now, Stephan. So I understand. Sounds easy, but I know how hard it is to make things as easy as you are describing right now. Yes, I absolutely agree with you. And one more thing on top of that is that I'm usually dealing with business people here, of course. And of course, business people also make sure that these concepts pay off, and that's where the entire process is considered. That really means from planning through commissioning to maintenance and optimization of systems; so all of this is considered in principle. And special attention is also paid to the fact that the systems in operation do not in principle burden the store staff, that nobody has to worry about them. A person responsible for real property at a large discounter once told me that his main concern is that you don't hear or see anything about a good system. Because it's important to him that he makes money selling and not managing technical problems. Okay, that's a clear message. So in one sentence it becomes pretty clear in which direction this is going. Definitely, and the same applies to data and fault management. The rule here is that an automatically generated report must be there, which includes facts and, ideally, recommendations for action. Fault reports must be automatically passed on to the service companies and also be trackable. In summary, you can say that a cost-effective overall solution is being sought that can be used universally, concentrates on the essentials and is as simple as possible. No easy task as you said But I definitely think it's feasible. Yes, very interesting. Especially with a view of this retail business. That's kind of a benchmark, I'll tell you what you just described. I find it very interesting! But for me, it can also transfer very well to the other things that you've just said. So on municipal requirements, public institutions, because the economic aspect is always a very, very important issue. Very interesting. Thank you, Stephan, for this insight into the world of retail, but also the management of buildings and distributed properties. For me a very, very interesting insight. Thank you! My pleasure, Daniel. For me, that was a very interesting insight into the world of distributed properties and we also heard what specific challenges one has in day-to-day project business, for example, in the retail environment. The question at this point is, of course, how can WAGO help? And I would like to answer that question for you today. At WAGO, we are launching a system solution this year that is primarily optimized for the requirements of distributed properties, but which can be used for many other applications as well. We are consistently expanding our range of preprogrammed solutions that require only configuration and we are expanding this range with our new Building Control Application. You can use WAGO Application Building Control for HVAC control, but also for lighting or shading. You can use the Building Control Application either on a single technical center, that is for a single system such as a single heating or ventilation system. However, you can also use the application for a complete property, for example, as we know from the area of distributed properties, such as the retail environment. The new system solution that we are bringing to market naturally consists of the aforementioned WAGO Application Building Control on the local controller on the one hand, but also of the WAGO Cloud Building Operation and Control. With the WAGO Cloud Building Operation and Control, we at WAGO are now bringing a completely new user and visualization interface to market for the first time that can be used to operate and control your systems directly from our WAGO Cloud. In this system, you have the option of connecting controllers to the cloud directly from the WAGO Application Building Control directly from the controller, directly from the configuration interface, without the need for any kind of gateway. To present this to you a little better now, I would like to switch to a topology next. So a slide where we can look at the whole thing a little more technically. And here you can already see our PFC controller with our WAGO Application Building Control. You have the option of connecting various hardware I/Os to the controller. In the first version, however, also M-Bus or Modbus®, for example. You have the option of operating the application locally from your PC or from a locally installed Touch Panel. But you also have the option of connecting the application directly to our WAGO Cloud Building Operation and Control. As I said, you have the option, you don't necessarily have to. In the next step, I would like to go into more detail about the WAGO Application Building Control and maybe show you one feature or another. Our Building Control Application, which you can now see here in the image, is a preprogrammed application, as I have just said, that you can configure directly from the Web Visualization. You can see this well in the screenshot here. I have just said that you can connect various hardware I/Os, M-Bus and Modbus®. You can connect these I/Os in this application and the application will automatically recognize the installed I/O modules aIO modules and will stop them for you already here, so you don't have to do any and list them for you so that you don't have to do any programming or configuration of your I/Os. All you have to do is name your data points. You also have an integrated dashboard in the application, but also integrated monitoring and alarms. And you have the option of integrating this class, this WAGO Building Control Application, for example, in a local building management system or transferring the data to another controller in the local building automation system. But you also have the option of connecting this application directly to our WAGO Cloud Building Operation and Control, which is already integrated in the application. As I said before, you don't have to, but you have the option in the configuration directly. And now I would like to show you something about this WAGO Cloud Building Operation and Control next. The WAGO Cloud Building Operation and Control is a higher-level operating and visualization interface. You have the option of structuring your systems, that is your various technical centers, your various heating and ventilation system. However, you also have the option of structuring all of your distributed properties and you have direct access to this operating and visualization interface from anywhere in the world. You no longer have to worry about software maintenance because the WAGO Cloud Building Operation and Control is, as the name suggests, in our WAGO Cloud. A higher-level alarm is integrated. This means that you can set up an alarm for all of your systems that you have activated. You have trends and reporting at this point and you have remote access to all of your controllers from the cloud interface, where you can either access web-based management to make configurations or directly to the visualization where you can control your systems from the cloud. You also have an integrated, complete device management system where you can manage your controller applications like a charm. The WAGO Cloud Building Operation and Control may not be the complete management system that you know from the past, but the WAGO Cloud Building Operation and Control has been optimized by us for your daily operational business. You can see exactly the data that you need for your daily operational business. You have barrier-free access from your browser from anywhere in the world. And so the WAGO Cloud Building Operation and Control should help you everyday in your business. So, that should be enough of the theoretical preface on my part. Now, let's take a look at the practical use of these applications. That's why we have Alexander Mackensen and Carsten Wendt here today, the two product managers responsible for our applications. Alexander Mackensen and Carsten Wendt will now show you the applications in concrete terms and also do some configurations with you. We want to start with Alexander Mackensen, who will show us the WAGO Application Building Control. Alexander will then be followed by Carsten Wendt with the WAGO Cloud Building Operation and Control. Here's Alexander Mackensen with the Building Control Application. Hello, I would like to introduce you to a new application for building automation. WAGO Building Control Application is a preprogrammed application solution for almost all areas of use in building automation, such as controlling heating, ventilation and air conditioning systems, lighting control, shading control or for capturing of energy consumption data. The great thing about this application solution is that, despite the preprogramming, you can set up any data points that can be linked to each another or provided with control and regulation functions. The solution is commissioned with a configuration interface based on the motto “Configuration instead of programming”. Knowledge of programming languages is not required for this solution. A dashboard for operating and visualizing the system is also integrated and you have the option of connecting the application to the WAGO Cloud Building Operation and Control for worldwide access to the data. I would now like to show you a small configuration example. We will implement a simple temperature control loop to illustrate creating the application, the principle of creation. To do this, I will switch to the application. You can see the start screen. I will log in. After logging in, the dashboard first appears. You can already see some elements that have been previously configured. But first, let's switch to the configuration area because we want to create a new function. On the left side of the screen, you can see a list of functionalities that are available to create your applications. For example, we have mathematical functions, evaluation functions, different controller types, logic links, If-Then conditions. You can set up a characteristic curve, timer programs, a wide variety of functionalities. If you want to create a new program or expand one, you usually start with the I/O configuration. The application automatically detects which I/O modules are installed and connected to the controller. These modules are shown here in a list. We now see, for example, a digital input module, a digital output module, two analog input modules, an analog output module and a serial interface. For our temperature control loop, which we want to configure now, we need some data points: an enabling signal, a current temperature, a setpoint and an output for controlling the heating valve. Let's start with the enabling signal. To do this, we select a digital input, look for the first free channel of the input in the application and enter a name for the data point there. We will use the name “Enable” here. You still have the option of assigning an additional designation, for example, where this control loop is located or what it is used for. We type in “Office”. Then you can also invert the value, for example, and then also see that the output is set directly to “switched ON”. As a further data point, we need a temperature. To do this, we switch to the temperature input module, look for the first free channel that is available and enter the data point designation here again. This time we'll use “Room temperature”. Here, too, there is the option of entering “Office” as an additional designation. You can choose the type of probe is to be used. In this example, we have selected a Pt1000 sensor. You can check whether the unit has been selected correctly. You may have to select a different unit. It's also very interesting that at this point, you can prepare the data point for data logging or for area monitoring – simply by activating the checkboxes. If I now, for example, increase the temperature value a bit increase the temperature value a bit and touch it here, then the value will change after a while. As you can see, it has just risen from 24 degrees to 24.8 degrees. So now we have the enabling signal, the room temperature, next we need a data point to control the heating valve. We use a digital output for this, select the first free channel here as well and assign the name of the data point as “Valve”. Here, too, an additional designation – we'll use “Office” again. You can enter a value range from 0 to 100 percent and you can now select how this data point should be controlled. In this case, we choose a PWM signal. It is also interesting at this point that if you want to test the wiring, for example, you can transfer the data point to manual operation and, for example, enter a value of 100 percent and the output switches and you can test whether the wiring is correct. And you can test if the wiring was done correctly. As soon as you do so, a message appears in the upper status bar to inform you that a data point has been set to manual mode. We're taking this back at this point. And the last data point that we now need for our temperature control loop is a setpoint in this example, we decide on an input field on the dashboard. I switch to the dashboard settings and create a new tile on the dashboard for operation. I'll give it a name: Temperature control loop. I can also use the additional designation “Office” here In the tile again, I enter a name for the target value, data point name, additional designation and at this point, I can now select how the data points should be displayed on the dashboard. In our case, we want to have a slider, a setpoint slider. I select an icon here. I still have to select the unit, degrees Celsius, and can now also enter a range in which the setpoint can be changed. Let's choose from 18 to 26 degrees. So here we can switch to the dashboard and see what the result looks like and you can see we have a new element here, a new temperature control loop tile with a setpoint slider that you can also operate with the mouse and the value can adjust accordingly. But now let's go back again. To complete this temperature control loop, we still need the functions. So far we have configured the data points. We still need the functions. We create a PID controller, a new PID controller, call it “Heating”, enter the additional designation “Office” and assign the data points to the PID controller at this point. We see the data point catalog for the first time. This is an important central element in the application because all data points that you have previously configured in the application appear here. This is, so to speak, a fulcrum to link the data points with one another. If you have already created several data points, the list will be very long. Therefore, you have a filter function here. We just kept typing the additional designation “Office”. Now, I'll filter for "Office" and you will see all data points that we have just configured. We now assign the enabling signal to the PID controller; assign the room temperature to the PID controller and also the setpoint that we have created on the dashboard. The last thing we have to do is link the output of the PID controller to the heating valve. To do this, I go back to the I/O configuration, select the digital output module, our heating valve and link this to the PID controller I just created. So, our temperature control loop is now functionally ready. A very interesting possibility and commissioning help is that we can now graphically display the values that we have created there. I also filter for “Office” here and take the room temperature, heating valve and setpoint. And now you have all three data points in one graph and can follow live how the values change and immediately check whether the function that you have just configured is also working for you. Now, I switch back to the dashboard. We have just created the target value slider in the dashboard. I add a new element to display values. And now we want to display the temperature profile. I select the data point to be recorded there, the room temperature and can choose the presentation mode here. I could choose a table so that the value is represented as a number. In this case, however, I want a graph, a line and I switch to the dashboard. And there we see a new element with the topic “Temperature curve". You can also change the size and position of the elements on the dashboard. We're doing it a little bigger here too. You can use it to design the dashboard the way you want it to be. If I now manipulate the temperature some again, for example, you will immediately see that the value is displayed there accordingly. Yes, lastly I would like to show you how connecting to the WAGO Cloud works. To do this, we go back to the configuration area, switch to the WAGO Cloud and you can now create a new collection or collection of data points that are to be transferred to the cloud. We assign a name “Temperature control loop”. You can now create various values that are to be transferred from the controller to the cloud. This is this area. We can again select different values here. Let's take the actual value and the setpoint. Or in the same sense, you could also transfer values from the cloud to the controller the other way around by assigning a data point name that activates and then this data point can be further processed in the application as input for further functionalities. It is also interesting up here that you can assign these values to a building system. This ensures that the data can be correctly interpreted and assigned on the cloud side. So let's choose “Heating”. Yes, that was the connection to the WAGO Cloud. As you can see, it's very simple. We are already done with our simple example of setting up the temperature control loop. You can configure functions such as inputs and outputs and insert functions in between. It is also possible to nest functions. For example, you can use the output of a function as the input of another function and with this principle of application setting, you are very flexible and can create applications quickly and efficiently and all in a very simple way following the motto “Configuration instead of programming”. Thank you! Thank you, Alexander, for the overview and detailed introduction to the functions of the WAGO Application Building Control. As I have already said, this application can stand on its own, of course, but it doesn't have to. The particular strength of the system comes into play when the WAGO Application Building Control is used in combination with WAGO Cloud Building Operation and Control. And that's why I'd like to hand things directly over now to our Cloud product manager, Carsten Wendt, who will then present the detailed functions of the WAGO Cloud Building Operation and Control. Let's all take a look together to see how to use the WAGO Cloud Building Operation and Control and how management of buildings and dispersed properties can work in actual practice. Hello and welcome! I'd like to briefly present the WAGO Cloud Building Operation and Control solution to you. What can you achieve using the Building Operation and Control application? You can use it to monitor and oversee your dispersed properties. You can write setpoints and actual values from the cloud to the property, to the controller. You can input and manage service contacts and service technicians. You can also set alarm values to help you monitor your properties. Let me show you briefly how this works. When I'm in the Cloud start window I can log in as a property manager and first show you how to link a controller with the WAGO Cloud. To do this, we first go to “Device management”. And the first thing we see here on the left is the structure, the existing structure of the dispersed properties. This is where we want to add a controller. To do this, go to “Configuration”. Click on the property that contains the controller. Now we see a list of daycare centers. Then we click “New”, select “Device” and confirm our selection and then specify a name to create the controller. Create the controller... automatically for a property. It appears immediately in the structure. And what do we need now? Two items of information are now shown on the right that we need to link the controller with the Cloud. One of these is the Device ID. Copy this to WordPad, for example. The second item is the activation code. Copy both of these items, save them and then go to your local PFC controller. There, go to “Cloud Connectivity” and enter these two codes in the Web Based Management system. The controller will then find its way to the Cloud the next time it is started up and actively connected to the Internet. The Cloud recognizes this controller by its device ID and activation code and connects it automatically with the subscription, with the structure. That's all you have to do. OK, so now let's take a look at property management. . As the property manager, let's first have a look at the structure. And the first thing we notice here is that a warning has been issued. This is what I meant when I explained that we can have alarms and warnings displayed using WAGO Cloud Building Operation and Control. In this case, we see a warning. How can I now get information about the warning? Where did it occur? There are easy ways of getting this information. One way is through the status overview. A new window then opens. In this window we get an overview for the property. As we have only one warning in this case, only one property is displayed. In the Bildung Operation and Control a distinction is made between the status “OK”, the status “Warning” and a “Critical alarm”. Critical alarms are shown at the very top of the hierarchy. In this case, only a warning is present. Now let's go to the property. We are now at the lowest level of the structure for the property. The first thing we see on the top page is a warning. We also see which alarms have occurred and, here in the structure, we can see that the office temperature is 16.8 degrees, . which is below the specified setpoint. Let's just have a look at this value. We open a display and see a value. We also have the option of viewing a different time window in the menu. We'll just have a look at this week to see if this error has occurred at any other time. How did it behave? Here we see that the setpoint fluctuated repeatedly in the last few hours As a property manager I cannot take any further step. I simply have to see which service or which service technician is responsible for this service group. Using Building Operation and Control, you have the option of notifying a service technician automatically by e-mail or text message in the event of an alarm or warning. If the contact person has been input, here the person for the “Heating” service group, you also have the option of notifying this person by phone or by e-mail that a warning or an alarm has occurred and that a service request has been initiated. Now I'll log in as a service technician to simulate here the function of a service technician in Building Operation and Control. As you see here, I've now signed in as a service technician. And you can see here in the start window, the service technician can select from other applications. We have implemented a role and authorization concept in Building Operation and Control. the service technician is only authorized to open the applications shown here. He is authorized for remote access, for alarms and for the property. Let's take a closer at this. Here, we see on the left that the service technician is authorized to view only one area, not only in the applications, but also for the hierarchy levels. and that we can assign authorization privileges in Building Operation and Control Strictly speaking, I can authorize a service technician for one property or for levels. In this case, the service technician is authorized only for the kindergarten. The service technician goes into the system and also sees here that the room temperature for the office is too low and, via the option “Remote access”, first links in to the local instance, to the local property on the PFC.To do this, we go to “Remote access”, connect to the controller and then select “Application BC”. Now we log in as “admin” on the controller. We confirm this again and then reach the application. And here it becomes obvious at a glance that the room temperature controller for the office setpoint was set too low. I then slide the setpoint up to 22/23 degrees to correctly set the setpoint. Then I disconnect from the controller and go to my overview, where I can have alarms displayed again. I go to the alarm and acknowledge it, thus ending my service assignment in just a few minutes, from log-in up to now, up to acknowledgement to cancel the alarm Now I log back into the WAGO Cloud as a property manager again. Once I'm logged in, my standard start window is displayed. I then go to the property. One option for getting to the property is what I presented at the beginning of the session, via the alarms. Another option is to specify a name in the Search function and to have this displayed directly here in the left window. I then return to the property. I'm back on the same property. Now I take a look: I've received the information information from the service technician that the alarm has been acknowledged. Now I take a look: I've received the Here, I can set the alarm to “canceled”, thus concluding the service request. OK, well that was one option with Building Operation and Control and a further one of course concerns Reporting. Monitoring and reporting function for one specific property, or monitoring or generating of reports for all dispersed properties. Now, I go back to the property. I'd like to show you a report To do this, we go the “Property” area. Click on the tab “Reports”. The first thing I'll show you here is the status, the status overview for the property. Let me just say here that this is not a PDF document that is saved and updated each month. No, here we are talking about direct access to data, and when a report is opened the data is read out from the database and the corresponding report information generated. Here we see a status report for the kindergarten. Energy consumption is shown, for example. We also have an overview of the progression of consumption: Is it positive/negative relative to the previous year/previous month and also a cost trend curve: Did I have to invest more for energy? How many alarms are there? How quickly were alarms acknowledged and subsequently canceled? Everything can be monitored here. You can also change the month as the sign here. Now I'll switch from January to February and you can see how the data is updated. The month of February now applies. Things look different here. This was the report for the property. We also have the same information in the global overview. Depending on the authorization privileges I've been assigned I can, of course, also view reports here. Logically, when you are on a property only the information for that property is given The associated energy consumption rates are combined the higher we go in the hierarchy. This may correspond to a city, a region, an entire country, or just a company. Here, I can aggregate the corresponding reports and display all the relevant information. In this case, we simply want to view heating consumption. Here in the overview we see the total consumption over all properties included in the work area. And here, presented a bit differently as a graph. This enables specific reports to be prepared completely individually and generated and created on customer request. Here we have an overview of energy consumption. We also have trend curves. And these also contain information. Of course this energy consumption changes when a new property is added. Daycare centers and kindergartens about the energy consumption at those locations. You are provided with a direct overview of where the greatest energy consumption is and where there is a change, also as a percentage. You can view all of this under the Report tab. That concludes my presentation in this brief session. Thank you for your attention. Thank you Carsten Wendt for your presentation of the WAGO Cloud Building Operation and Control. Today we got a brief look into the requirements of dispersed properties. We saw the new system solution that WAGO will be introducing onto the market this year and were given a look into the controller application and at the new operating and visualization interface in the cloud. I hope this has given you a bit of insight into the world of dispersed properties and that we have been able to show you some of the solutions offered by WAGO in this sector and in the sector of HVAC control. And it goes without saying that you are cordially invited to stop by our digital trade fair booth, or contact me in a chat or in a direct conversation. And of course our colleagues are always available to assist you via digital contact on our trade fair platform.
