1 KNX Association: A Brief Outline KNX Association has been set up in 1999 with headquarters in Brussels as the merger between three former European associations promoting intelligent homes and buildings, i.e.:

BCI (France) promoting the Batibus system; EIB Association (Belgium) promoting the EIB system; European Home Systems Association (Holland) promoting the EHS system.

KNX Association has the following goals:

definition of a new truly open standard ‘KNX’ for intelligent homes and buildings; establishing the KNX Trademark as a token for quality and multi-vendor interworking; establishing KNX as the European and worldwide standard.

As long as needed, KNX Association also offers support for the legacy systems Batibus, EIB and EHS, including certification according to these previous standards. As EIB is backward compatible to KNX, most devices can be labelled both with the KNX as well as the EIB logo.

2 Goals of the KNX Association

Definition of testing and quality standards via working and expert groups(KNX Specifications)

Technical Hotline for manufacturers developing KNX compatible devices

Issue of KNX Trademark on the basis of specifications through KNXCertification

National and International Standardization Activities

Promotion of training measures by certification of training centers

Promotional activities (web site, trade fairs, brochures, …)

Encouraging forming of national groups

Scientific Partnership for Technical institutes

Rest specification work/promotion/certification of legacy systems

Figure 1: Goals of the KNX Association

KNX Association consisted of 9 members when it was founded: this number has meanwhile increased to more than 125 (until June 2008), including companies that were before not a member in any of the legacy associations. These companies represent more than 80% of the European market for installation devices and white goods. The current membership list is available at any time under www.knx.org. As far as the legacy associations is concerned,

the Batibus Club was transformed into the national group KNX France; the KNX Association has taken over the development and sale of the KNX software

packages from EIBA Brussels. This amongst others includes the ETS™ (Engineering Tool Software) (see later);

EHSA will be integrated in the KNX structures.

At the end of 2003, the KNX Standard was approved by CENELEC (European Committee of Electrotechnical Standardisation) as the European Standard for Home and Building Electronic Systems as part of the EN 50090 Series. The KNX Standard was also approved by CEN (EN 13321-1 for media and protocol and EN 13321-2 for KNXnet/IP). At the end of 2006, KNX was also approved as a world standard (ISO/IEC 14543-3). In 2007, the Chinese translation of the international standard achieved GB/Z status as GB/Z 20965.

Figure 1: Topology - Line

1 Topology Each bus device (DVC) can exchange information with any other device by means of telegrams. One line consists of a maximum of 4 line segments, each with a maximum of 64 bus devices. Each segment requires an appropriate power supply.1 The actual number of devices is dependent on the power supply selected and the power input of the individual devices.

1 This chapter assumes the use of central power supply units only. For distributed power supply

units, consult chapter ‘TP1 installation’.

Figure 2: Topology - Area

2 Topology: Area If more than 1 line is to be used or if a different structure is to be selected, then up to 15 lines can be connected to a main line via a line coupler (LC). This is called an area. It is also possible to have up to 64 bus devices on the main line. The maximum number of bus devices on the main line decreases by the number of line couplers in use. Each line, including the main line, must have its own power supply unit. Line repeaters may not be used on backbone or main lines.

1 THE ETS 3 PROFESSIONAL SOFTWARE: GENERAL ASPECTS

1.1 General aspects KNX is a comprehensive, integrated system for home and building automation for the implementation of upwardly compatible, flexible and cost-effective solutions. Due to its functional versatility, its use is not confined to simple and limited installations but also enables solutions for the complete building sector. KNX fulfils the requirements of electrical installers during project design and installation, commissioning, operation of the bus system through to maintenance. For planning, project design and commissioning of a KNX installation, a software tool for planners and electrical installers is needed that is both clearly structured and easy to use. A comprehensive Online Help is also included in the tool. Via the F1 button, the user has access to context-sensitive help, which is directly related to the current program section. The planning and design of a building, in which one intends to use KNX is no different than conventional electrical design. In the initial phase, the planner must consider the following:

the type and use of the building the building system components to be used and their functions, the type and frequency of changes in usage, any special requirements of the building contractor, the cost implications.

The planning of the electrical installation is carried out as in conventional installations in accordance with the general accepted rules for electrotechnical installations and the conditions for connection as laid down by the electricity supply company. The standard guidelines and rules for planning, execution and dimensioning must also be observed.

1.2 Concept of ETS 3 Professional A software tool is made available to planners and electrical installers for the planning, project design and commissioning of KNX systems. ETS stands for Engineering Tool Software1. ETS TM is a registered trademark of the KNX Association in Brussels. Although the ETS 3 Professional is a completely new developed software, great emphasis was laid during its development on keeping the user interface as similar as possible to the previous version, i.e. ETS 2. The user interface of the ETS 3 was however completely revised as regards presentation and operating philosophy. The presentation and operation of the software was adapted to current standards, as known for instance from MS Windows Explorer. In this way operation and orientation have been substantially simplified compared to ETS 2.

1.3 System requirements The following minimum system configuration is needed when using the ETS 3 Professional (recommended values are in brackets):

PC with 400 MHz (1 GHz) processor 128 MB (256 MB) RAM MS Windows 98 / ME / 2000 / NT4 / XP True colour VGA 800x600 (1024x768) Hard disk with 3 GB of free memory Interfaces: RS 232 or USB

These values apply for standard projects without so-called plug-in software. For more complex projects or projects with products requiring a plug-in software, the following higher system requirements apply:

PC with 1 GHz (2 GHz) processor 256 MB (512 MB) RAM

Figure 2: Licensing

1.5 Licensing With the ETS 3 Professional, a new licensing procedure is introduced. There are 4 versions of the ETS 3:

Demo: max. 1 project, max. 20 devices, no bus access, Trainee: max. 1 project, max. 20 devices, no export, otherwise full functionality Full version: with PC dependent key or with a PC independent dongle Supplementary version. This version is intended as an extra license to a full version

for a second PC (Commissioning/Notebook). This version is also available with a PC dependent key or with a PC independent dongle.

Regardless of which mode it will run in after installation, the ETS 3 Professional is fully installed. The mode depends on the license key that is entered. After the installation, the program will first run in Demo mode. You can access the license request and installation window when starting ETS 3 Professional or via the menu item Extras/Licensing… in the menu bar. The window offers the choice of licensing a full version, trainee version or a supplementary version. Further dialogs for requesting the license key and for unlocking the software will give you detailed information about how to proceed. You will also find a detailed description of the licenses and the procedure on the ETS 3 CD.

KNX BASIC COURSE


1.6 Project design with ETS 3 Professional - Principles The following steps constitute a fundamental sequence when designing with ETS 3 Professional.

Make the necessary settings in ETS 3 Professional Import or convert the product databases Create the project and fill in the necessary data Set up the project structure (building structure/bus topology) Insert KNX devices (devices and their corresponding applications) into the building

structure Set the parameters of the KNX products according to the requirements of your instal-

lation Create group addresses Link the group objects of the KNX products with the group addresses Assign the inserted KNX products to the bus topology (final definition of the individual

address) Assign the inserted KNX products to the created functions Check the project design Print out the documentation Save your project

In special cases, it may be necessary to deviate from this sequence. For smaller projects, some of these steps may be skipped in some cases, whereas more complex projects (team projects) may require some additional design work.

GENERAL NOTES

1 Commissioning

1.1 Commissioning requirements It is not compulsory for the commissioning of a KNX installation to have a complete installation of the bus system with all the bus devices. In larger projects (several building sections), it is advisable e.g. to pre-program the bus couplers in the office or in the workshop. As the complete data set does not necessarily need to be downloaded into the bus coupler during commissioning, it is a good idea to first download the individual addresses into the bus couplers and then the remaining relevant data once the bus couplers are already installed in the system. Regardless of whether the commissioning is carried out in the office, the workshop or on the building site, the application modules of the flush-mounted devices should not yet be installed so that the programming button and the programming LED are accessible. In distribution boards, the covers should be removed so that the programming buttons and LEDs of these KNX devices are also accessible. For built-in devices in suspended ceilings or luminaries, it is a good idea to provide them at least with an individual address in the workshop as these devices are generally difficult to access once they have been installed. The stipulated checks during and after the installation must be completed successfully. Commissioning can be done via:

A serial interface A USB interface Or a network connection

on the commissioning PC. The required settings will be explained in detail in the paragraph “Bus access” and “Configuring the interface”.

ETS 3 Commissioning 217

KNX BASIC COURSE


If the serial interface of the PC is a 9-pin plug, the contacts must connect the serial cable to the KNX data interface (Pin1 on Pin1, Pin2 on Pin2… Pin9 on Pin9). Since ETS 3, it is also possible to commission a KNX installation via USB. In both cases, the corresponding settings must be carried out (see also setting the local individual address or interface). ETS 3 enables all functions to either be retrieved from the menu bar or via the context menu (right mouse button). A large number of functions can also be started directly from the toolbar via icons. The ETS 3 program thus behaves in the same way as the majority of programs which run under the Windows TM operating system. All the following screenshots only show examples. The functions must not necessarily be retrieved in the way that is described here. Initially, it is worthwhile to use the right mouse button as often as possible as it takes you directly to your required destination in most cases.

Figure 1: Local or imported projects

1.2 Local or imported projects The project of the KNX installation must be contained in the database (e.g.“eib.db”) for commissioning purposes. If the project has been configured on another PC, there are two possibilities available: The first option involves exporting the project with ETS 3 and importing it on the commissioning PC. The necessary steps are described in the “Project Design” chapter. It should however be ensured that all the additional installed programs e.g. for LC displays are also installed on the commissioning PC.


KNX BASIC COURSE


The second option involves copying the entire database (e.g. “eib.db”) from the first PC onto the second PC. This process has the benefit that all the products are contained in the database should an expansion be required at a later date. The disadvantage is that the database can become very large under certain conditions (several 100 MB). The database must either be burnt onto a CD or copied using a network connection or via another data storage medium. It should moreover be noted whether the database contains products which can only run with additional files (DLLs, parameter files etc.). These must be copied with the correct paths. The recommendations of the manufacturer must be observed!

Figure 2: Starting the commissioning

2 Starting the commissioning The following menu icons are responsible for the commissioning or diagnostics:

“Online” Prepares the PC for bus access

“Download” opens the Download dialog for individual addresses and programs

“Device Info” opens the Device Info dialog

“Bus Monitor” opens the bus monitor

“Group Monitor” opens the group monitor

Furthermore you will find the following functions under the “Commissioning” resp. “Diagnostics” menu:

“Unload” A commissioned device will be set back to its original state when selected

“Reset Device” will send a restart command to a bus device

“Individual Addresses” Compares the devices in the installation to the ones in the project


KNX BASIC COURSE


Figure 3: Bus access

2.1 Bus access Before the commissioning can be started, it is necessary to connect the interface for bus communication with an appropriate cable connection to the commissioning PC and to choose the correct setting on the commissioning PC. This can either be a serial interface (RS232), a USB interface or a network connection. Irrespective of which interface has been chosen, the communication settings in ETS should be checked before the initial commissioning phase. The submenu item “Options” is located under the “Extras” menu. The “Communication” window contains the corresponding setting options.
