HDL KNX System Introduction

KNX Introduction KNX- International standard of Home and Building Automation KNX organization Founded in 1999, head office - Brussels, Belgium Member companies : ABB, Siemens, Schneider, HDL..., more than 200 producers Organization website http://www.knx.org

KNX BUS EIB = European Installation Bus KNX = EIB + BatiBUS + EHSA KNX transmission media： Twist Pair – EIB：the most widely used Power Line - Batibus Radio Frequency - EHSA IP/Ethernet

KNX System Structure - Line 1.1.1 1.1.63 A line can have 64 devices The Max. length of one line is 1000 meters The Max. length of two devices on the same line is 700 meters The Max. length between the power supply and a device is 350 meters

KNX System Structure - Area Main line 1.0 Line 1 Line 15 LC1 LC15 1.15.1 1.15.63 1.1.1 1.1.63 1.1.0 1.15.0 Area An area can have 15 lines Every line is connected to main line via a line coupler The main line needs a separate power supply module

PA – Physical Address LC1 LC15 Area15 Area1 Physical Address indicates the physical location the device locates in, assign an unique physical ID to every device by ETS according to the device’s physical installation position.

Target/Control Object Object can send or receive telegram Every object has fixed control type(DPT: Data Point Type), e.g. on/off, relative dimming, etc. Every object has fixed data type and length. 220V A B Dimmer Object1：on/off 1bit Object2：relative dimming 4bit Object3：absolute dimming 8bit

GA – Group Address Group Address is a link, to achieve the control function. With same group address, the objects can communicate with each other, e.g., if you want to use button A to control relay channel C, then you need to assign a GA to both of them. 1. GA format: X/Y/Z Main group/middle group/sub-group X=0-15, Y=0-7, Z=1-255 2. Group address 0/0/0 is reserved for broadcast 3. One object can link with more than one group addresses 4. Different objects can link with same group address

ETS - Introdunction ETS is a configuration tool software made by KNX organization, the newest version is ETS5, however ETS3.0f is still widely used. When purchase a KNX product from a company, you will also receive a database of the product, you can then import the product database to ETS software and configure it, and finally upload your configuration to the product.

ETS - Create Database name your new project database double click click ‘new’ to create your project database click the icon in the manu bar to add project, click 'OK' then it will dispaly the windows for this project

ETS - Import Database Steps: manu bar->file->import->select database ->import the selected one or import all

ETS - Add Device Steps: new line->add device->find-> select the imported database->insert

Tips for Database Version Please check the production version from the module label, and use the corresponding database. For MOSFET Dimmer, production version V1.0 & V1.1---database V1.1; production version V1.2---database V1.2 For other devices: production version V1.0---database V1.0; production version V1.1---database V1.1; production version V1.2---database V1.2. 2017/4/26

ETS - Physical Address double click change physical address

ETS - Group Address 1- select the object 2- right-click to select 'link with...' option 3- assign group address for it: create new group address link with existing group address

ETS - Build Communication

Example - DLP + Dimmer Create a project and name it as 'Dimming', add one DLP(M/DLP04.1 ) database and one 4CH MOS Dimmer(M/D04.1) database in area1, line1. The M/DLP04.1 default physical address is 1.1.1, the M/D04.1's is 1.1.2. The default enabled object function of the DLP is switching(on/off) and the dimmer's is channel output(on/off) & relative dimming

Example - DLP + Dimmer Right-click the M/D04.1, select 'edit parameters' to enter the configuration page, enable the 1 bit response function for each channel.

Example - DLP + Dimmer Right-click channnel objects of dimmer, select 'link with...' to assign group addresses for them, here all group addresses are the new one, then select 'create new group address', set the address value then click 'OK'

Example - DLP + Dimmer Right-click the M/DLP04.1, select 'edit parameters' to enter the configuration page, select 'Dimming controller' work mode and 'Single button' operation mode for Rocker A & B

Example - DLP + Dimmer Right-click Rocker A&B objects of DLP, select 'link with...' to assign group addresses for them, here all group addresses need to be corresponding with the dimmer's, then select 'link with existing group address', set the address value then click 'OK'

Example - DLP + Dimmer 1- Right-click the M/DLP04.1, select 'Download...' 2- Select 'Program Address & Application' 3- Press the first and last buttons of DLP at the same time, it will enter the programming mode and its button LED will fresh 4- Start download

Example1 - DLP + Dimmer 1- Right-click the M/D04.1, select 'Download...' 2- Select 'Program Address & Application' 3- Press the 'PROG' button of dimmer, it will enter the programming mode and its LED will turn red 4- Start download

About Downloading Program Individual Address: Download physical address to device (need to press the PROG button to let it enter the programming mode) Download Application Program: Download configuration to device (if you know its physical address, just click this option to download the configuration directly) Program Address & Application: Download physical address and the configuration to device (if you donot know its physical address, click this option to download both of them, need to press the PROG button to let it enter the programming mode)

Combined Application 1 KNX bus fan coil unit DLP+FCU M/DLP04.1 M/FCU01.10.1 KNX bus HVAC can read temp from bus or local module. if read temp from local, must connect with the digital temp sensor. TS/C 1.0 digital temperature sensor
