1. Introduction
The XNC KNX provides the functionality for an IQ3 Controller to be able to communicate with a
KNX network. The IQ3 Controller will be able to read 130 different KNX variables and write
another 70 KNX variables.
The 200 KNX variables available to the IQ3 Controller can be combined with your KNX network
in the ETS3 software.
With the XNC KNX comes a piece of hardware which works as a gateway between the IQ3
Controller and the KNX network. The gateway is called the XNC KNX Gateway.

2. XNC KNX Gateway
The XNC KNX Gateway hardware has the following layout.
1. RJ45 connector for ethernet network with the IQ3 Controller
2. Power for the XNC KNX Gateway. 24V DC
3. Short circuit these two connectors equals KNX Program Address button press
4. Insert two wires for the Twisting Pair connection to the KNX network
One red wire and one black wire
The XNC KNX Gateway should be mounted on a DIN rail.
Dimensions of the XNC KNX Gateway. The units are millimeters.
•Height 100 mm
•Width 75 mm
•Depth 70 mm

2.1. XNC KNX Gateway settings
There is a webpage server on the XNC KNX Gateway. It is possible to configure the several
different settings. The XNC KNX Gateway is preprogrammed with a static IP of 10.0.0.149. To
enter the webpage use the following link.
http://10.0.0.149
The address will be different if the IP has been changed on the XNC KNX Gateway.
There is needed a login for entering the webpages to configure the different settings. Following
users are created on the XNC KNX Gateway.
User: admin
Password: wago
In the settings it is possible to setup the network configuration under TCP/IP or change the user
access on XNC KNX Gateway webpages under Security.

3. XNC download
The KNX XNC driver consists of two files:
●.xnc file – Application file
●.xnp file – Configuration file
Quick list for the installation:
1. Download the strategy with the .xnp file
2. Download the .xnc file
p. 6
3.1. Download the strategy with the . np file
Start up SET (System Engineering Tool) and open your strategy. Right-click on the strategy with
the mouse and you will get a menu popping up. In the menu choose “Device”->”XNC Interface
Module”.
XNC Interface module is opened then press the “...” button which can be seen in the next
screenshot marked by a red ring. There will be an open dialog and you can choose the .xnp file.
Now download the strategy to the Trend Controller.
p. 7
3.2. Download the . nc file
Switch to “System View” and find the Trend Controller. Right-click on it and choose “Download
IQ3/XNC Application”. This will open a new dialog where you press the “Open File” button and an
open dialog will appear which is used to find the .xnc file.
Now press the download button and the KNX XNC driver will be installed on the Trend Controller
but still needs configuration.

4. XNC KNX variables
With the IQ3 Controller and XNC KNX it is possible to read or write XNC KNX variables. Here is a
full list of the different variable types.
XNC KNX variable Size Description
Switch 1 Can be ON (1) or OFF (0)
Switch Control 2 Like Switch but can also be deactived (0) or activated (1)
Small Value 1 Unsigned 8 bit contains numbers 0
Value 1 Unsigned 16 bit contains numbers 0 to 65535
Value Negative 1 Signed 16 bit contains numbers -32767 to +32767
Value Decimal 1 16 bit Float contains decimal numbers
Big Value Decimal 1 32 bit Float contains a wider range of decimal numbers
Date 3 Contains Year (only last 2 digits), Month and Day
Time 4 Contains Day of week, Hours, Minutes and Seconds
Here is a list with the amount of each XNC KNX variable type supported by the XNC KNX.
XNC KNX variable Read Amount Write Amount
Switch 25 20
Switch Control 8 5
Small Value 20 15
Value 15 5
Value Negative 15 5
Value Decimal 20 10
Big Value Decimal 20 10
Date 1 0
Time 1 0

5. Supported KNX Datapoint Types
In your KNX network you will have several different KNX Datapoint Types. Here is a list with all the
KNX Datapoint Types supported by the XNC KNX. Each type of XNC KNX variables only support a
certain amount of different KNX Datapoint Types. DPT is short for Datapoint Type.
