Automation solutions for data centers
Zhejiang Dafeng Industry, China
Anyone whose mind is on sustainability, CO2 savings, and the social responsibility we have to achieve global climate goals has a crucial question to ask themselves: What solutions are available to significantly reduce a large share of global energy consumption – that is to say, energy consumption in buildings? This question is not only an ecological one, it is increasingly also an economic one. Investors and operators have overlapping interests, in that only buildings that have been optimized in terms of energy efficiency and that feature appropriate energy monitoring and energy metering solutions are buildings that are fit for the future.
With building automation across all technical systems – such as we are offering with PC-based control – sustainable, energy-efficient construction and living can be implemented in the sense of a green building. All technical systems are integrated on a single platform. All participants in the building value chain benefit from this: Architects enjoy maximum creative freedom with optimal functional efficiency; specialist planners are provided with increased planning reliability with reduced complexity; system integrators benefit from simplified engineering and increased process reliability; operators minimize their operating costs and maintenance work; investors are provided with the greatest possible investment protection.
At a glance: your benefits in building automation with PC-based control
All data points in a single system
Heating, ventilation and air conditioning (HVAC)
With the TwinCAT 3 Building Automation software library, a comprehensive package of function blocks is available for building automation that covers the entire range of functions of the HVAC control. This significantly simplifies the work of the system integrator in the implementation of heating, ventilation and air conditioning technology. Functions such as summer night cooling, summer compensation, backup operation and time schedulers are also available. With the help of the HVAC modules, further energy-saving possibilities can be exploited by the occupancy-dependent control of technical systems.
Room automation
Illumination, solar protection, window control, heating, ventilation, and air conditioning are linked with one another on a central platform in room automation for the intelligent control of all technical systems. This reduces the number of individual physical data points and thus the susceptibility to errors. In addition, the provision of all data in one system is the basic prerequisite for successful energy monitoring. The thermal automation solar protection functions and the lighting solution for daylight-dependent illumination control contribute significantly to energy savings. Classic room control units can also be easily integrated via KNX/EIB, Modbus, and EnOcean.
Media technology
Through support for the common protocols and interfaces of media and building technology, our automation platform is able to address all industry-typical devices and systems. Moreover, the integration of AV and media technology and building automation opens up new possibilities, e.g. for the simple control and operation of multimedia devices in meeting and conference rooms.
Operating and monitoring
Depending on the building type or function, the customer-specific requirements vary with regard to remote maintenance, energy and consumption data acquisition, compressed air monitoring and scheduling, etc. The TwinCAT HMI software is perfectly suited to the visualization of all building control and monitoring data. The visualization can be done on a local panel PC or a control panel connected to an industrial PC or embedded controller. However, any HTML5-capable browser, e.g. on smartphones or tablets, can also be used for HMI visualization. The TwinCAT IoT functions also enable simple and secure communication with cloud services.
The modular range of automation components for building automation
With a comprehensive construction kit of modular and scalable software and hardware components, we offer a made-to-measure control solution for every task in building automation that is precisely tailored in terms of performance, cost and available installation space. The powerful, PC-based automation platform is responsible for control, data processing, connectivity, visualization, remote maintenance, and cloud integration. Due to the open interfaces in software and hardware, it is optimally suited to the central or decentralized control of all technical systems. Control can take place locally or in the cloud.
From the powerful industrial PCs for the management and control level, the embedded PCs for the automation level to the bus terminal controllers for room automation, you benefit from maximally scalable performance. With around 1,000 different I/O terminals, our bus terminal system supports all commonly available sensors and actuators as well as the fieldbus systems typically used in building automation. The fine granularity of the system makes it possible to insert only as many inputs or outputs as the respective project requires. The TwinCAT Database Server can be integrated into project planning to connect the building automation to commonly available databases. In conjunction with the TwinCAT IoT functions, data storage and monitoring can also be implemented in the cloud.
Building automation: the key to future-proof buildings
Future-proof buildings must meet diverse guidelines and standards with regard to energy efficiency and sustainability. Automation technology can be used to implement all relevant standards, such as EN 15232. This describes the influence of building automation and building management on energy efficiency and includes a structured list of all building automation functions and their influence on energy efficiency. In addition, EN 15232 provides methodical support for the definition of minimum requirements for building automation. As a general rule, the higher the degree of automation, the higher the energy savings. Energy efficiency class A of DIN EN 15232 is achieved with a PC-based control solution from Beckhoff and the optimized functions in the TwinCAT 3 Building Automation software library. Operators benefit from the ISO 50001-ready status and can be exempted from the energy allocation charge through the recording of all energy consumption.
A high Smart Readiness Indicator can also be implemented with Beckhoff. The standard defined by the EPBD indicates the level of a building's ability to intelligently adapt functions according to demand. For example, a room should only be heated and lit when someone is in it: Sensors detect the presence status and regulate the corresponding building functions automatically. PC-based control makes all the data collected available on a central platform as the basis for intelligent energy management.
IoT functions enable intelligent building automation
Energy data acquisition and management, and the resulting opportunities for optimization, are becoming increasingly important for modern building automation. Cloud systems play a central role in data handling. With building automation from Beckhoff, integrated communication from the I/O level to the cloud can be implemented with TwinCAT IoT functions.
A key benefit of cloud integration is the ability to combine multiple properties into one portfolio. This enables direct comparison of building data and thus performance monitoring as well. Anomalies in energy consumption can be quickly identified and investigated by comparisons with similar buildings. Monitoring and notification of faults can be performed centrally and from any location using devices such as smartphones or tablets. TwinCAT Analytics also enables building data to be analyzed directly in the cloud. The use of databases allows cost-effective storage of data over a long period of time and comparison with rule-based analyses. With predictive maintenance, problems caused by wear or contamination can be detected before failure occurs. Machine learning concepts enable the optimization of operating strategies and control algorithms over the entire operating time and service life.
With the supplements available in TwinCAT (e.g. HTTP/Rest, MQTT or OPC UA), no further devices are required for integration with cloud systems. Communication takes place directly from the TwinCAT control to the cloud. This makes the controllers from Beckhoff perfect for use as edge devices.

Intelligent building automation with PC-based control
Our PC-based control technology has proven itself worldwide since 1980 in the widest variety of applications, from the machine controller and the automation of wind turbines to building automation and has developed very quickly into a standard in the automation industry. Innovative product developments followed continuously and are regarded today as milestones in automation technology, such as the modular Bus Terminal system or the high-speed fieldbus EtherCAT. The basis for the universal usability of our control solution is its modularity, its scalability in terms of power and its openness toward other systems.
PC-based control enables the integrated automation of all trades: from HVAC to room automation, from remote maintenance and energy data acquisition to operation and monitoring. For this purpose, Beckhoff offers an extensive toolkit of hardware and software components, which can be used both in individual trades and across systems. Robust industrial or embedded PCs with the universal automation software TwinCAT integrate PLC, visualization, safety technology and measurement tasks. The Beckhoff I/O systems log data from all sensors and actuators. EtherCAT, the real-time fieldbus system, provides for the high communication speed. Through support for all common protocols and interfaces of media and building technology, our automation platform is able to address all industry-typical devices and systems. Due to the modularity of the system, only a new I/O signal has to be integrated into the terminal segment in the case of a function extension. For diagnostic functions like intelligent energy monitoring, various TwinCAT software libraries are available.
Your advantage with PC-based control:
- cost-effectiveness: from investment to implementation to usage
- sustainability: with today's technologies for tomorrow's requirements
- networking: all information is available on one platform
- flexibility: in order to react to users' individual needs
- high availability: through the use of open standards
EtherCAT Terminals automate any functionality in building services
In 2003, Beckhoff developed the fast EtherCAT communication system. Launched as an open system, it became a global standard in automation within a few years. With around 100 signal types, we offer an extensive EtherCAT Terminal portfolio that is extremely well suited for automating every functionality in building applications in terms of both its performance and variance. The terminals enable a variety of simple building bus systems such as KNX/EIB, DALI-2, DMX, M-Bus, BACnet MSTP to be integrated into the controller. This ensures compatibility and continuity with the existing system. Existing and future investments are protected.
In contrast to the Bus Terminals, in which the fieldbus signal is converted in the Bus Coupler to the internal, fieldbus-neutral terminal bus, the EtherCAT protocol is completely preserved up to the individual terminal with EtherCAT Terminals. This enables BACnet MSTP, DMX and SMPTE-Timecode to be integrated into the controller.
Universal function block for building automation: Beckhoff Bus Terminal
I/O signals are wired decentralized to fieldbus devices or centrally to the controller. The available vendor-specific fieldbus devices with fixed input/output configurations and design often make it necessary to use an entire group of devices with similar functions. This complex signal acquisition results in high material, installation, design and documentation expenditures as well as high costs for later changes.
The Beckhoff Bus Terminal is an open and fieldbus-neutral I/O system consisting of electronic terminal blocks. The head of an electronic terminal block is the Bus Coupler with the interface to the fieldbus. Bus Couplers are available for all leading fieldbus systems. With the master terminals, fieldbus functionalities are also available in the form of a standard Bus Terminal. This is particularly advantageous for bus systems that are integrated as subsystems into a higher-level system. It means that only one system is required for the subsystem and for the higher-level bus interface. The master terminals are available for the following building bus systems: KNX/EIB, DALI/DALI-2, DMX, MP-bus, M-bus, SMI, EnOcean, Modbus and others.

An extensive portfolio of ready-to-use applications is available. These are tried-and-tested and well-documented program blocks, ranging from applications in heating, ventilation and air conditioning technology to room automation functions and lighting control. They simplify the familiarization with the system and ensure a high level of system functionality. This increases the reusability and maintainability of the programs created. For the integration of the Beckhoff control into a management and control level, communication via BACnet and OPC UA is integrated directly into the templates.
The system operation and parameterization can be carried out directly at the control cabinet via panel or remotely by means of an integrated HTML5 web visualization via TwinCAT HMI. All basic operating and monitoring functions of building automation, such as system graphics, scheduling, alarm and event lists, are supported.
The BACnet solution from Beckhoff: scalable performance and wide range of functions
The international BACnet standard, which guarantees interoperability in building automation between devices from different manufacturers, is becoming increasingly important and is constantly being supplemented with new functions. TwinCAT BACnet can be used as a universal Ethernet protocol on all PC-based hardware platforms from Beckhoff, right down to the field level. The DIN rail-mountable Embedded PC series CX8191, CX9020, CX51xx the ultra-compact Industrial PCs of the C60xx series and Panel PCs are certified according to the BACnet standard ISO 16484-5 Protocol, Revision 14, and offer a control platform that is scalable in terms of performance. In accordance with AMEV BACnet 2017, the AS-B application profile (extended BACnet functionality) meets the stringent requirements of public and private building operators for the supported BACnet functionality.
With the integration of the BACnet protocol into the TwinCAT System Manager it is possible to efficiently configure Bus Terminals and BACnet devices with a single tool. BACnet servers and clients can be created in a structured manner from the PLC; BACnet properties can be accessed directly from the PLC. These capabilities also enable the efficient implementation of visualization components. Another function is the dynamic creation of BACnet objects, which can be used to create and configure time schedules and trend objects. Our solution was developed completely in-house, drawing on the profound knowledge of our industry experts.

A DVI-I interface allows the CX51xx to be connected to a Beckhoff panel for operation and monitoring. The performance class of the CX51xx allows an HMI to run in addition to the PLC. Media technology can also be integrated flexibly with the common protocols via TwinCAT. Thus, you have a controller at hand that covers the entire spectrum in the building, from the control of heating, ventilation, and air conditioning to room automation and from energy measurement to the cloud
CX7000: the variably usable small controller in the building
The CX70xx Embedded PC is ideal for implementing small stand-alone solutions in the building, such as a small ventilation system. The CX7000 is also ideally suited for room automation. With its eight integrated multifunction inputs and four multifunction outputs, it is a very inexpensive compact controller.

Pre-installed standard functionalities cover all necessary functions for room control, thus simplifying commissioning. In addition to integrated I/O signals and a sub bus connection for room control units, the BC9191 has a K-bus interface and thus enables modular extension using our Bus Terminals.
Changes to room automation functions are possible in the TwinCAT development environment and save complex rewiring, as would be the case with wired controllers. As a freely programmable Ethernet controller the BC9191 can also be used as decentralized intelligence and thus offers the greatest possible flexibility in the construction of system-spanning, energy-efficient room automation.
EL6861: BACnet MS/TP terminal
The EL6861 serial interface enables the connection of BACnet MS/TP devices (master-slave/token passing) via an RS485 interface. Up to 32 MS/TP devices can be connected – and up to 64 if using ultra-low power transceivers. Use the EL6861 only in combination with TwinCAT and a CX9020 as a minimum, since the BACnet MS/TP driver integrated in TwinCAT implements the communication via the MS/TP protocol (BACnet Revision 12). The configuration is also done in TwinCAT.
The following devices are typically connected to the EL6861:
- frequency converters
- pumps
- drives (especially valve drives)
- room control units
- compact controllers (e.g., volume flow regulators)
DMX terminals
DMX is the standard protocol for controlling professional stage and effect lighting equipment. This is used, for example, for the dynamic lighting of showrooms and salesrooms as well as for exclusive plays of light and color in hotels and event centers. Color mixing and brightness values are transmitted to DMX devices that are static light sources, while moving sources of light also receive spatial coordinates. EtherCAT’s high data transfer rate enables light settings to be updated at a higher rate, with the result that changes of light and color are perceived by the eye as being more harmonious. With the EL6851 DMX master terminal, DMX devices with three axes such as scanners, moving heads or spotlights can be controlled. In addition, the EL6851 can also be used to drive the RDM (Remote Device Management) protocol. TwinCAT offers associated libraries.
The EL6851-0010 DMX slave terminal enables the conntection of DMX consoles (or other DMX master forms). In this way, any DMX console can be integrated as an operating unit for the Beckhoff controller. The EL6851-0010 also allows the input data of the DMX console to be linked to any other signals in the control system by the Beckhoff controller. We also offer the integration of light consoles via sACN, Art-Net™, PosiStageNet or OSC.

The lighting devices are detected and controlled in the correct operation mode. Integrated diagnostics indicate the operating states by means of LEDs and make the status data available via the bus system. The electronic dimmer is extremely compact and is equipped with automatic load detection.
KL2602-0010: Bus Terminal for contact-protecting switching
The KL2602-0010 output terminal has two relays each of which has a single contact. The relay terminal is designed for soft switching at the zero voltage crossing to protect the contacts and is particularly suitable for capacitive loads such as LED lamps. The Bus Terminal indicates its signal state by means of light emitting diodes.
Blind terminals simplify the shading of buildings
Solar protection plays an increasingly important role in today's climate conditions and the focus on energy saving. We offer a comprehensive component portfolio for blind control. The KL2722 bus terminal with internal locking logic is suitable for standard applications such as blinds or venetian blinds with a 230 V drive. The KL2602 is available for roller shutter drives.

The display size of 7 and 10.1 inches is large enough for the local operation and monitoring of the systems. EtherCAT support can be used to connect the required I/O terminals and subsidiary bus systems to the Panel PC. The second Ethernet port can be used to connect the Panel PC to other systems and the Building Management System, such as BACnet/IP or the OPC UA protocol.
The fast way to an individual HMI
TwinCAT HMI makes consistent use of widely used IT standards such as HTML5, JavaScript and CSS. Through the integration of a fully graphical editor with an extensive toolbox in the familiar TwinCAT 3 engineering environment, it is possible to create extensive visualizations with little effort. Customer-specific functions that are not part of the visualization toolkit can be implemented using the IT standards mentioned above or via higher-level programming languages. The visualizations created are platform-independent and responsive on the client side. The powerful underlying architecture makes numerous application scenarios possible: from local panel solutions to multi-client, multi-server and multi-runtime configurations.
Instead of using proprietary systems, Beckhoff relies on IT standards:
- Visual Studio® for engineering
- HTML5 for design
- TLS for secure communications
- the user interface runs on any HTML5-enabled browser – regardless of operating system, resolution or display
Easy and secure cloud conntection with Beckhoff IoT
TwinCAT IoT enables the seamless connection of the control platform to cloud services. The IoT connection can be realized either via the Beckhoff controller or to a third-party controller – or even without a controller at all via the Beckhoff IoT coupler. Standardized protocols such as AMQP, MQTT and OPC UA are available for simple and secure communication with the cloud. The TwinCAT IoT Communicator app allows direct mobile access to TwinCAT process data. The complete data acquisition in synchronization with the cycle takes place via TwinCAT Analytics, enabling data storage in the cloud and predictive maintenance of buildings and plants.
With the TwinCAT IoT functions, system integrators can shorten the engineering process, react more quickly to changes of plan and integrate or retrofit the connection of a private or public cloud directly into the standard controller. The integration of a cloud connection into the controller gives building operators fast access to all recorded energy consumption data from any location and at any time. Clear trend recordings form the basis for improved energy management in the smart building. Unusual events in the operating sequence, such as a sharp increase in water consumption, can be reported to the operator as an alarm. In this way, a pipe breakage can be detected at an early stage and consequential damage can be avoided.
Beckhoff supports OPC UA as an integrated communication platform
OPC UA is gaining importance at all levels of the automation pyramid: scalability ranges from the small 15 KB footprint in embedded sensors to the ERP level in the case of SAP and the cloud. OPC UA has its origins in automation technology, but is neutral and is therefore increasingly used as a universal communication platform in the areas of building automation and smart metering. OPC UA provides platform independence as well as scalability from the sensor to the ERP/cloud level. Security-by-Design provides security concepts with user authentication, message signing and the encryption of transferred user data already in the OPC UA stack. It is precisely the specification of information models that makes OPC UA interesting for other organizations. They can organize their existing objects in the UA namespace, i.e. defining "What is being communicated?", while OPC UA regulates the secure transport and access rights in terms of "How will communication take place?"
