Automation in buildings aims to combine individual room functions with one another and to simplify the implementation of individual customer preferences. KNX is the logical development for implementing traditional and new requirements in electrical building installations and thus replacing The conventional solution: Many separate cables, separate functionality, little flexibility 2 2CDC 500 043 B0202 conventional installation techniques. The intelligent installation bus system efficiently performs the conventional functions and offers an additional broad range of expanded features, which could not be realized without a bus system. ABB offers consultants, system integrators and electrical installers a comprehensive product range with ABB i-bus® KNX, in order to meet the challenges posed to electrical building installations both today and in the future. The intelligent solution: KNX – a system, a standard, many interoperable functions for maximum flexibility Actuators (command recipients) 230 V KNX bus Sensors (issue commands) 2CDC 500 043 B0202 3 What does KNX stand for? KNX – The standard The KNX system is the leading intelligent control system for buildings world-wide. KNX resulted from the merger of major bus systems, including the wellknown EIB (European Installation Bus) that has been successfully on the market since 1992. What does KNX stand for? – KNX is the first globally standardized system for the automation of residential and non-residential buildings in accordance with the international standard (ISO/IEC 14543-3), the European standard (CENELEC EN 50090, CEN EN 13321-1 and 13321-2), the Chinese standard (GB/Z 20965) and the US standard (ANSI/ASHRAE 135). – KNX has established a clearly defined system platform where the KNX products of different manufacturers can be operated with one another. – Both the data protocol and the devices are certified compliant to the KNX standard. – KNX thus guarantees the networkability, interoperability, is both upward and downward compatible and thus future-proof. – Just one common software tool is required for planning, engineering and commissioning of all KNX installations. – Both the manufacturers and the KNX Association support professionals during planning, commissioning and maintenance worldwide. 4 2CDC 500 043 B0202 – Comprehensive training opportunities are available for beginners and experienced users in certified training centres. – More than 170 internationally certified manufacturers are members of the KNX association. – More than 22,000 qualified KNX partners plan, install and integrate KNX systems worldwide. – Thousands of buildings, ranging from private houses to airport complexes around the world, are equipped with more than 10 million KNX products. 2CDC 500 043 B0202 5 Intelligent Building Control for consultants, system integrators and electrical installers Benefits for professionals Efficient planning Economic installation Fast integration Simple to commission Flexible expansion 6 2CDC 500 043 B0202 Benefits for customers Comfortable to operate Comprehensive functionality Quick to change and expand Energy saving Future-proof investment What does KNX do? Application The use of new materials and the application of renewable energies are considered as the most significant innovations in the building industry over the last few years. The growing desire for comfort and functionality simultaneously with the limited availability of resources and increasing energy costs provide the basis for intelligent building control in modern constructions. KNX interconnects all the components in the electrical installation to form a networked system and thus guarantees the transparency and utilization of information across the installation. In this system, all users “communicate” via a single bus cable. Thus it is possible to integrate all the different fuctional subsystems within the building into a seamless solution. KNX bus systems can be used both in residential and non-residential buildings. Applications – Lighting – Climate control – Sun protection – Security – Energy management – Operation – Automation – Communication 2CDC 500 043 B0202 7 Energy efficiency with ABB i-bus® KNX Energy savings in the double-figure % range Climate change and growing shortages of resources are the big challenges of our time. Efficient and sustainable energy usage is therefore an urgent necessity. Scientific studies and measured values in practice show a high energy saving potential when bus technology is used in room and building automation. The ABB i-bus® KNX intelligent building control system provides its customers with a broad range of options for optimum energy efficiency. * BACS: Building automation and control system ** TBM: Technical building management Building Automation and Control (BAC) efficiency classes to EN 15232 A High efficiency BACS* and TBM** B Advanced BACS and TBM C Standard BACS D Non energy efficient BACS 8 2CDC 500 043 B0202 On the basis of the KNX standard, energy in the double-figure % range can be saved. Around the world new legislation is promoting the use of energy efficient technologies. In Europe, for example, the criteria for energy efficiency in buildings is detailed in the European Standard EN 15232; the allocation into energy efficiency classes A to D serves as the basis for the evaluation. The following diagram shows the differences in energy consumption for three building types in the energy efficiency classes A, B and D relative to the basis values in class C. For example, by using class A, 30% of the thermal energy can be saved in offices. Efficiency factor Efficiency factor for electric energy for thermal energy Office School Hotel Office School Hotel 0.70 0.80 0.68 0.87 0.86 0.90 0.80 0.88 0.85 0.93 0.93 0.95 1 1 1 1 1 1 1.51 1.20 1.31 1.10 1.07 1.07 2CDC 500 043 B0202 9 Energy efficiency with ABB i-bus® KNX Energy savings in the double-figure % range In principle, optimization of the energy consumption in buildings means – Energy is only consumed when it is actually needed (for example through the usage of presence detectors) – Only the amount of energy actually required is used (for example through the use of constant lighting control) – The energy used is employed at the highest possible degree of efficiency (for example through the use of electronic ballasts) Using the versitile functionality that intelligent building control offers real energy savings can be made. ABB i-bus® KNX is making a significant contribution to global climate protection and at the same time reducing operating costs in today’s buildings. Potential savings according to scientific studies Room heating control Heating automation Shutter control Lighting control Air-conditioning control about 14 about 7 about 9 about 25 about 20 to to to to to 25 % 17 % 32 % 58 % 45 % In total, the average energy savings that result through optimization with KNX lie in the range of 11 to 31%. 10 2CDC 500 043 B0202 How does ABB i-bus® KNX work? Intelligent building control in detail Within the KNX bus system, all sensors (e.g. buttons or motion detectors) are interconnected to the actuators (e.g. dimming actuators, roller shutter actuators) via a data cable as opposed to directly wired switches and consumers (conventional installation). The actuators control the power circuit to the consumer. Communication for all devices is implemented using data telegrams on the same bus cable. The sensors send commands, actuators “listen in” and execute a defined function as soon as they are addressed. A broad range of functions can be parameterized with ABB i-bus® KNX, such as group commands, logical sequences, control and regulation tasks. 2CDC 500 043 B0202 11 System integration What does system integration mean? During system integration, all the requirements of the investor or building owner are implemented using KNX devices and the respective product software. 1. Planning During planning, the preliminary requirements of the building owner are incorporated into the concept and are summarized in the functional description. 2. Engineering The most suitable components and software applications are selected. The planning of the bus topology is realized during the engineering phase. The system devices required for implementing the KNX network are defined. The project engineering using the ETS on the basis of the functional description also takes place in this phase. 12 2CDC 500 043 B0202 3. Commissioning During the commissioning phase, the KNX devices are installed and programmed. The ETS project that has already been created is downloaded into the devices using the ETS software. 4. Handover During the handover phase, the programmed functions are checked for compliance to the requirements in the functional description. In this way, the correct function of the installation can be determined and documented. 5. Documentation The customer receives the project documentation (schematics, function description and ETS project data) after the handover. 2CDC 500 043 B0202 13 The elements of the “intelligent building control system” Management, structure and topology The communication medium – the KNX cable In simple terms, the KNX bus consists of a pair of twisted-pair wires (cable type, e.g. YCYM 2 x 2 x 0.8 or J-H(ST) H 2 x 2 x 0.8 halogenfree) that connect the KNX devices. Over this cable, data telegrams are transmitted, and the electronics of the bus devices are supplied with energy. The KNX system can also be extended over IP-Networks and using RF solutions. The KNX structure The KNX structure created is very flexible in its design due to the possible connection of the devices: linear, tree and star wiring configurations are allowed. The KNX topology The KNX topology is arranged in lines that can be interconnected via couplers depending on the size of the network. The devices in the respective lines (sensors and actuators) are supplied with energy by a power supply (30 V) whereby the entire KNX bus system can be configured with more than 50.000 bus devices. 14 2CDC 500 043 B0202 Schematic representation of the KNX bus Power Supply/ Line Coupler KNX NX X bus bus Tree wiring Line wiring COPY ROOM OFFICE OFFICE CORRIDOR OFFICE OFFICE Star wiring OFFICE OFFICE OFFICE OFFICE OFFICE 2CDC 500 043 B0202 15 KNX Telegram Structure Telegram Structure Devices communicate with one another using “telegrams” which are sent via the bus. A telegram consists of bus-specific information and the actual user information in which the event (e.g. pressing of a button) is communicated. The entire information is sent packaged as characters each 8 bit long. Control byte Source address Destination address Length User information Check sum up to 16 x 8 8 bit Rooting counter 8 bit 16 8 bit 8 16 + 1 8 8 3 8 4 8 8 8 8 bit Telegram Acknowlegdement After the telegram has been received by the devices, it will then send a receipt of acknowledgement. D7 N 1 0 1 D6 N 1 0 1 B = 00 BUSY D5 0 0 0 0 D4 0 0 0 0 D3 B 0 1 1 D2 B 0 1 1 D1 0 0 0 0 D0 0 0 0 0 Read direction of the data bit Acknowledge message BUSY still busy NAK receipt not correct ACK receipt correct N = 00 NAK NAK By acknowledging with NAK (receipt not correct) the telegram is repeated up to three times. Busy By acknowledging with BUSY the transmitting device will wait for a short time and then resend the telegram. End If the sending device does not receive an acknowledgement, the telegram is repeated up to three times before the sent request is terminated. 16 2CDC 500 043 B0202 Flags Setting of the Flags Caution: The flags should only be modified in exceptional cases! Flags are settings in the ETS. The behaviour of each communication object can be set on the bus by using flags. Communication flags ✔ The communication object has a normal connection to the bus. – Telegrams are acknowledged, but the communication object is not changed. Read flag ✔ The object value can be read out via the bus. – The object value cannot be read via the bus. Write flag ✔ The object value can be modified via the bus. – The object value cannot be modified via the bus. Transmit flag ✔ If (on the sensor) the object value is changed, a corresponding telegram is sent. – The communication object only sends a response telegram with a read request. Update flag ✔ Value response telegrams are interpreted as write commands, the value of the communication object is updated. (always enabled in the BA – mask version 1.0 – 1.2). – Value response telegrams are interpreted as write commands, the value of the communication object is not changed. (✔) = flag set / (–) = flag not set 2CDC 500 043 B0202 17 Data Formats Definition of the Data Formats / EIS Types EIS is the designation for the “KNX Interworking Standard”. This standard defined by the KNX association stipulates the manufacturer-independent characteristics for the user information of the telegram.

Check for compliance of allowable line lengths. 2. Visual inspection for marking of bus cable ends. 3. Check for incorrect cable connections. 4. Measure the isolation resistance of the bus lines. 5. Polarity test of all bus nodes. 6. Measure the voltage on the bus cable ends (mind. 21 V). Additions to the points above 1. The maximum permissible bus line lengths are defined by the voltage drops and the capacitances of the bus cables, and thus the telegram transmission times. The measurement of the loop impedance of the bus line concerned can prove to be useful. Line lengths within a line 70 00 0m 700 350 3 35 50 m SV TLN TLN TLN TLN Total length 1000 m TLN In each place, the following line length limits: TLN Power Supply – Participant Participant – Participant TLN Total – Cable length 350 m 700 m 1000 m KNX Restrictions – Permissible cable length in a line is max. 1000 m – Distance between voltage supply – bus device is max. 350 m – Distance between two voltage supplies incl. choke is min. 200 m – Distance between two devices is max. 700 m 20 2CDC 500 043 B0202 2. The ends of the bus cables should be labelled with “KNX” or “bus” clearly identifying them as the installation bus. Furthermore, details of the area and line will assist in the location of specific bus lines. 3. Different lines may only be connected using a (line) coupler. Inadmissible connections between the individual lines can be verified by switching off the power supply on the lines to be checked. If the power LED continues to light on the line coupler, an inadmissible connection has been made. 4. The insulation resistance of the bus cable should be measured with DC 250 V (DIN VDE 0100 part 610). The insulation resistance should be at least 250 kOhms. Measurement is performed from the conductor to PE, and not conductor to conductor. CAUTION: Overvoltage surge protection connectors should be removed before testing in order to avoid influencing the measurement or avoid damaging the surge protectors. 5. The polarity test should be performed on all bus devices. For this purpose switch to programming mode on the bus device with the programming button. The bus device is correctly connected if the LED lights up. By renewed pressing of the programming button the bus device is switched over to operating mode and the programming LED switches off. 6. The bus voltage should be checked with a voltmeter at the end of every bus cable after all bus devices have been installed. It must be at least 21 V. 2CDC 500 043 B0202 21 Topology IP Hierarchy IP networks have now become standard in larger buildings. These networks can also be used to transmit KNX telegrams. A flat hierarchy can be established by the use of IP gateways and IP routers which feature similar functionalities as line and area couplers. 255 KNX lines can be compiled to an IP world. 255 IP worlds can also co-exist on a LAN or WAN. Thus, even sections of the building which are further away can be integrated into the system. Router Switch Visualization PC IP Router IPR/S 2.1 IP Router IPR/S 2.1 IP Router IPR/S 2.1 KNX line 1 KNX line 2 KNX line 3 ... IP Router IPR/S 2.1 KNX line n Replacement of line or area couplers by IP routers facilitates higher data speeds between devices. It combines interfacing of other systems (e.g. building control engineering or visualization) to the KNX via the IP network using OPC. KNX devices can be programmed via the IP network and remote access (remote programming or remote control) is possible via the Internet. 22 2CDC 500 043 B0202 Tips and Tricks Commissioning Before we commence with commissioning, the – RS 232/USB interface must be programmed locally to suit the line. Failure to do so will mean the line couplers cannot be correctly programmed. – Program the line couplers, possibly, setting the parameters then to route all telegrams unfiltered. – ETS diagnostics ensures that no bus device is in programming mode. (programming button pressed, programming LED lights up.) Commissioning of the bus devices – Initially all of the bus devices will be physically addressed. – If all devices are physically programmed, we can commence loading the applications. (In order to save time, the applications should be loaded during a break, e.g. lunch. – The following points should be checked if communication problems occur: – The RS 232/USB interface is not physically programmed. – A device with an address corresponding to line x is located in another line. – Two different lines are interconnected with each other. – The line couplers are not programmed. Caution: Line couplers must always be programmed at the start of commissioning. If they are not programmed, they interfere with the bus communication. ETS4 enables simultaneous programming of devices in several lines in conjunction with the connection with IP routers. This helps you to save time during set-up. 2CDC 500 043 B0202 23 Checklist Functionality / Customer Requirements Lighting ❍ Operation from one or more positions ❍ Operation from one or more positions
