Schneider Electric - IS&C training academy – Trond Høyem
Basic arguments

What is KNX?
The three letters “KNX” stands for:
…………………………………….
However….
●KNX is a bus system
●KNX is a world standard
●KNX brings building functions together
●KNX offers flexibility, safety, comfort and cost efficiency

Conventional installation
●Every function is realized with one or
more cables
●More functions = more cables
●Each function must be planned in detail
before installation
●If a function should be changed, the
physical installation has to be changed
●Each device is used for one function only
●Even low level interaction between
different functions become complex and
cost intensive

Bus installation
●Separation of information and energy
●Only one cable (the bus) for all
information = less control cables
●Functions depends on programming
= logical connections between inputs
and outputs replaces physical
connections
●Change of functions without touching
the installation is possible
●Multiple use of single devices
●Complex interaction between
different functions are easy
Bus

Savings with KNX

The demand for energy efficiency
●Today there is a high demand for more energy efficient buildings
●The directive 2002-91-EC states that all countries in Europe should have
some kind of energy labelling on their buildings
●The standard EN 15232 defines what kind of functions are mandatory to
achieve an energy efficient building
●KNX is an easy way to accomplish energy efficiency
Classification of functions Example of classification of
buildings (France)

The use of EC-norms
Directive 2002-91-EC
EN 15232

Directive 2002-91-EC
●This important European directive from 2002 laid the base for all the following
norms, that developed the boundary conditions to calculate and rank
energy consumptions of different trades in buildings.
●As the directive is not directly fixing any methods and transferred that to the
member countries, SeeTool uses the main objective to introduce the
important topic of saving energy and reducing emissions by using
Building Control products from Schneider Electric.
● Furthermore one of the key mandates creating a classification system for the
building’s energy consumption is used at the tool to value the
calculated savings (Report). The used classification by kWh/(m2xa) from A to G
can be localized on the countries individual classification values.

EN 15232
●The EN 15232 is one of the first norms defining and valuing the
impact of building automation and control systems.
● SeeTool is using the classification of control functions to create
applications which are following the A-class and therefore are representing
today’s by norm defined highest automation standard.
●The calculation methods of SeeTool are following the direct or
operation mode approach as they are taking into account the
environmental conditions of the buildings location. The in EN 15232
defined factor method approach is thereby always a benchmark to
value our calculated results.

Basics info
●The standard EN 15232 has been prepared by Technical Committee
CEN/TC247 << Building Automation, controls and building management >>
and was approved on May 2007.
●Drafted within a framework of a mandate given to the CEN by the European
Commission and European Association of Free Exchange to support the
requirements of EU Directive 2002/91/EC relating to the Energy
Performance of Buildings (EPBD).
●Designed to establish the conventions and methods intended to estimate the
impact of automatic regulation and technical building management
(TBM) systems on the energy performance and needs of buildings.

Basic content
●This standard …
● provides guidance for tasking BACS &
TBM functions
● supplements a series of standards (Energy
Performance of Buildings)
● is used for existing buildings as well as for
design of new or renovated buildings
● specifies calculation methods of impacts
on energy performance
● guides a simple classification of control
functions and their simple evaluate by using
BAC efficiency factors

Connections to other standards

BAC and TBM Efficiency classes
●4 different Efficiency classes (A,B,C,D) for functions are defined either for
residential and non-residential buildings
Building with such systems shall be retrofitted
New buildings shall not be built with such systems

Classification example
●Lighting control – Occupancy/Daylight control

Solutions as a package
“Application” stands for “Solution”
●Idea
● Based on the analysis of customer behaviour and practice,
we defined generic application packages. Easy to understand and follow.
● and products.
●Practice

Calculation and results
What happens in the background

What are we calculating?
●Estimated consumption of a benchmark
room in function class C
●Estimated consumption of a KNX
controlled room in function class A
●The savings is the difference between
the two calculations
●More than 70 parameters are calculated
●Only some of them can be altered
in the SeeTool.
See training documentation for detailed description of the calculation
Room
Central functions

What is the benchmark?
Fixed benchmark room parameters:
User occupancy: 100% = e.g. 8 hours/day
Lighting control: Manual on/off
Temperature Setpoint at 24hours a day
No shutter and blind used.
No daylight saving used.
Configurable project room parameters (default):
User occupancy: 80% daily, and 90 % yearly occupancy
Lighting control: Automatic, presence and/or daylight controlled
Temperature control: setpoint - 3°C at non occupancy hours +automatic
reduction based on presence
At available shutter and blind function: Window covering 100%
Parameters defining the compare between benchmark and project:
Deciding factors for the compare and therefore difference between the benchmark and
projected situation is on one side the time using the room = occupancy time,
and on the other side the selected functional equipment, that dependant on the room’s
characteristic and location more or less allows to reduce the consumed energy.

What are the savings?
● Energy Total savings compared total energy consumed
for lighting, heating & cooling
● Electricity savings compared energy consumption for
lighting
● Heating & Cooling savings compared energy consumption for
heating &/or cooling
● CO2 savings compared CO2 emissions,
dependent on defined generation
for energy production

System data
●Max 64 addresses
● Be aware that some lights may have more than one ballast
●Max 16 groups, 16 scenes
●All lamps can be controlled by means of broadcast
●Some KNX interfaces can control each lamp individually
●No DALI push buttons or sensors can be used together with a KNX/DALI
interface
●Independent of polarity
●Baud rate 1,2 kbit/sek
●Recommended cable; 1,5 mm2

Installation tips DALI
●Always use cable with area of minimum 1,5 mm2
●At larger DALI projects it can be wise to commission the DALI bus in parts of
10 devices
●It is important that all installation work on the DALI bus is finished before the
SI starts the commissioning

Communication

Bus access and data exchange
● KNX is a decentralized and event-controlled
bus system, i.e. no central unit, and the bus
is idle (free) if nothing happens or changes
● All connected bus devices can exchange
data between each other, packed into
telegrams and sent over the bus (serial
transmission of “1” and “0”), e.g. from a
sensor (the command output) to one or more
actuators (the command receiver).
● CSMA/CA (Carrier Sense Multiple Access /
Collision Avoidance) is used for bus access
and collision handling
● Transmission rate: 9600 bit/s
● Average transmission time for sending and
confirmation of a telegram is approx. 25 ms

Command sender
● When Button 1 is pressed a telegram with group
address 1/1/1 will be sent on the bus via the
Switch object
● The function and thereby the value in the
telegram is pre-defined in the parameters, e.g.
toggle-function = the actual object value is
inverted and sent on the bus, i.e. every press
sends alternately ON- and OFF-telegrams
● The telegram will be received by all the sensors
and actuators on the bus
Command receivers
● When telegram 1/1/1 comes to the actuator it
will be evaluated and control the relay of
Channel 1. If the value is 1 (ON) the relay will
close and if the value is 0 (OFF) the relay will
open.
● The actuator sends an acknowledge telegram
● Other actuators and sensors which does not
have the group address 1/1/1 assigned will
not evaluate and acknowledge the telegram

Communication flags
Communication The group object has a normal link to the bus
Telegrams are acknowledged. The group object is not modified
Read The object value can be read via the bus
The object value CANNOT be read via the bus
Write The object value can be modified via the bus
The object value CANNOT be modified via the bus
Transmit A telegram is transmitted when the object value (at the sensor) has been
modified
The group object will generate a response only when receiving a read
request
Update Value response telegrams are interpreted as a write command. The value
of the group object is updated (always enabled in System 1 devices)
Value response telegrams are NOT interpreted as a write command. The
value of the group object remains unchanged.
Read on Init The device independently sends Read value commands for the initialization
of the group object after return of current (only available on certain masks)
After return of current the device does not initialize the value of the assigned
group object via Read Value commands

TP1 Bit structure
„0“ and „1“ are the two logical states a bit can possess.
Technical logic in KNX TP1:
During a logic 1, no current drawn
During logic 0, current drawn
This implies that – when several
devices are sending
simultaneously, the one sending
a „0“ may continue to send
Logical state
Signal
voltage

Telegram Collision
Bus device 1
Bus device 2
On the bus
Transmission from bus device 2 is aborted,
and will be repeated after a delay
The bus devices listen to the bus while transmitting.
As soon as a bus device with the logical state “1” detects the logical state “0” (=flow
of current on the line), it stops transmitting to give way to the other sending device.

Planning the installation

- IS&C – Trond Høyem
Most used process models
1. Volumes are described. Functions might not be described in first step
● Planner has good knowledge of KNX or similar system
● The buyer will in the end be the one responsible for the volumes in the project
2. Function are described. Both volumes and solution are up to the bidder to
decide
● Planner do not have a wide knowledge of KNX, or do not care what system is
used, only that the functions needed are fulfilled
● Bidder will be the one responsible for the volumes in the project

Planning the installation 1st steps
●Decide what process model to use on the actual project
●Decide the application needs of the customer
● Light, heating, cooling, blinds, integration to other systems
●Decide what kind of light control to use
● DALI
● 0-10V
● ”Normal” dimming
●Decide the way to control blinds
● Relay control
● Gateway to intelligent blind motors
●What kind of heating/cooling will be installed
● Radiators, fan coils, electrical heating, cooling from ventilation etc

Planning the installation, designing topology
●KNX is normally planned with no more that 50 devices pr line
●One should create a topology view that indicates where the different lines and
areas will be in the building
●The topology view should also indicate if the project will have KNX/IP router
as line or backbone coupler
●The lines must be drawn in the floor plan with the devices
● Device addresses can be added at a later stage

Planning the installation, add KNX devices
●No matter the process model used, at one point someone needs to plan the
installation in detail so that the correct devices can be purchased
●Devices can be planned and added in ETS
●Devices can be planned and added in a CAD program
●Devices can be planned and added in a spread sheet like Excel or similar

Exercises

Exercises
●We are to design a KNX system in a building. The following control functions
should be controlled by KNX:
●Constant light control in offices based on DALI lamps and KNX light sensor.
There is also a demand for manual control of the light.
●Heating and cooling control.
● Heating is done with radiator under each window
● Cooling is done by a simple cooling radiator in the ceiling (no fan coil).
●Blind control separate for each room with window.
●There is no heating in meeting rooms, only cooling.
●Light control in meeting rooms:
● Scene function with two scenes
● Push button at both doors
● Movement sensor with IR receiver for remote control of the light
● 2 light zones, one for general light and one for the board. All on DALI.

Exercise 1, design topology view
●In each floor of our building there are 3 distribution boards
●We will install system components for the necessary lines in all distribution
boards
●In each floor we have a total of 360 devices. From each distribution board
there will be 120 devices connected
●In the basement there is only the main distribution board and a total of 96
KNX devices
●On the supplied topology view sheet, please draw a possible solution for the
topology including the line couplers and back bone couplers, but without the
power supplies.
●Indicate the addresses of the system components and the line numbers on
the lines

Exercise 2, DALI
●Draw the DALI bus on the floor plan. Remember that one can only have 64
devices and 16 light groups on each DALI bus.
●How many DALI buses are needed in this floor?

Exercise 3, KNX devices
●Draw the needed KNX devices in one office space.
●Draw the needed KNX devices in one of the meeting rooms
●Draw the needed KNX devices in the corridor and other common rooms.

Exercise 4, KNX lines
●On the floor plan called KNX draw the KNX cable(s) needed. Remember that
the maximum number of devices on each line should be 50 when planning the
installation
●How many lines are needed in this floor plan?
●Why did you choose the line structure you did?

ETS3

Engineering Tool Software
●The only software for commissioning
KNX products
●Independent of supplier
●Developed by KNX association in
Brussels

Commissioning

Commissioning KNX
● All commissioning is done by ETS
● Exceptions for some special products. Touch panels, visualization etc
● The database of each needed device must be imported to your ETS
● The programmer should have at least the KNX certification training
● Some product training might also be needed, depending on the complexity of the
products

Commissioning steps
1. Design the topology
2. Design the building view in ETS
3. Assign devices to rooms, cabinets and to the topology
4. Download individual addresses
5. Set up the parameters as needed for the chosen applications
6. Create group addresses and assign the group objects of the devices to the
group addresses
7. Download application
8. Test the installation

What do one need to clarify before
commissioning?
●Topology must be clear. This is in some cases done by the planner and in
some cases done by the SI
●Interfaces between KNX and other systems in the building
●Naming of group addresses
● This is important both for the interfaces between KNX and other systems and for
the understanding of the project at a later point
● Proposal: Geografy | Trade | Zone | Function
● Example: B01_401 light ceiling lamp sw
●Interface between installer and SI, if not same company

Addressing the devices
●Addressing prior to installation
● All devices are connected to a temporary KNX bus at the SI’s office and addresses
are downloaded
● All devices must be labeled with the correct Individual Address
● Individual addresses must be entered on the drawing
● High degree of training of the installer is needed
●Addressing on the site
● All devices are addressed by walking around pressing the programming button
● Does not require that addresses are entered in the documentation

Documentation
What documents should be demanded

Documentation of a KNX installation
●Overview of the topology as build
●Drawings of the cables and distributed devices as build
● Including individual addresses of KNX devices
● Also the DALI numbering
●Drawings of the distribution boards as build
● Also principal drawings of connections for the different applications and products
used
●Documentation of the different products used
●User manuals for the end user
●Also remember that the project file from ETS must be part of the
documentation

What to demand from the SI
●Explanation of the different applications used
● User manuals for the end user
● Detailed explanation for the next programmer
●Clear explanation of the group address structure and the naming of group
addresses
●The SI should document KNX competence. Minimum competence should be
KNX certification
