8 KNX Security
The KNX standard was extended by KNX Security to protect KNX installations from unauthorized
access. KNX Security reliably prevents the monitoring of communication as well as the
manipulation of the system.
The specification for KNX Security distinguishes between KNX IP Security and KNX Data Security.
KNX IP Security protects the communication over IP while on KNX TP the communication remains
unencrypted. Thus, KNX IP Security can also be used in existing KNX systems and with non-
secure KNX TP devices.
KNX Data Security describes the encryption on telegram level. This means that the telegrams on
the twisted pair bus or via RF (radio frequency) are also encrypted.
Encrypted telegrams are longer than the previously used unencrypted ones. For secure
programming via the bus, it is therefore necessary that the interface used (e.g. USB)
and any intermediate line couplers support the so called KNX long frames.

9 Interface settings in the ETS
In the ETS, interfaces can be selected and configured via the ETS menu “Bus –Interfaces”. All
available connections are listed under “Discovered Interfaces”. After clicking on the desired
interface, connection specific information and options appear on the right side of the ETS window.
Via the “Select”button, the selected interface can be set as “Current Interface”.
In the “Individual Address”section, the currently used individual KNX address can be changed. To
check if the desired individual address is not already available in your KNX installation, the button
“Address free?”can be pressed.
Furthermore, the “Domain Address”can be changed in the next section.

10 Local download
With the KNX RF / ENO Push Button 440 secure it is possible to program the device via the
integrated USB interface (from ETS version 5.7.5). This saves the battery and significantly reduces
the download time. To be able to load the KNX RF / ENO Push Button 440 secure via the
integrated USB interface, it must be selected as the default interface in ETS. See the section
“Interface settings in the ETS”.
If the KNX RF / ENO Push Button 440 secure is selected in the project and “Download” is pressed,
a dialog appears where the individual address and the domain address of the interface can be
changed.

© 2022 WEINZIERL ENGINEERING GmbH Seite 11/36
The addresses can be entered in the following dialog.
The “Individual Address”of the interface should correspond to the device address in the project.
The “Domain Address”to be set can be found in the properties dialog of the corresponding radio
line.

© 2022 WEINZIERL ENGINEERING GmbH Seite 12/36
The settings for the example should look like this.
After confirmation the ETS offers in the next step the programming of the device via the local USB
interface.
If the local interface is activated in the group monitor of the ETS, then no local download
is possible.

11 ETS database
The ETS5 database (for ETS 5.7 or newer) can be downloaded from the product website of the
KNX RF / ENO Push Button 440 secure (www.weinzierl.de) or from the ETS online catalogue.
The KNX RF / ENO Push Button 440 secure supports KNX Data Security to protect the device
against unauthorized access from the KNX bus. If the device is programmed via the KNX bus, this
is done with encrypted telegrams.
11.1 Secure commissioning
If the first product is inserted into a project with KNX Security, the ETS prompts you to enter a
project password.
This password protects the ETS project from unauthorized access. This password is not a key that
is used for KNX communication. The entry of the password can be bypassed with "Cancel", but
this is not recommended for security reasons.
ETS requires a device certificate for each device with KNX Security that is created in the ETS. This
certificate contains the serial number of the device as well as an initial key (FDSK = Factory
Default Setup Key).

© 2022 WEINZIERL ENGINEERING GmbH Seite 14/36
The certificate is printed as text on the device. It can also be scanned from the printed QR code via
a webcam.
The list of all device certificates can be managed in the ETS panel Reports –Project Security.
This initial key is required to safely put a device into operation from the start. Even if the ETS
download is recorded by a third party, the third party has no access to the secured devices
afterwards. During the first secure download, the initial key is replaced by the ETS with a new key
that is generated individually for each device. This prevents persons or devices who may know the
initial key from accessing the device. The initial key is reactivated after a reset to factory default
settings.
The serial number in the certificate enables the ETS to assign the correct key to a device during a
download.

© 2022 WEINZIERL ENGINEERING GmbH Seite 15/36
In the ETS project in the properties of the device, secure commissioning can be activated and the
device certificate can be added:

11.2 Secure group communication
Each object of the device can communicate either encrypted or unencrypted. The encryption is set
under "Security" in the properties of the used group address:
The setting "Automatic" activates encryption if both objects to be connected can communicate
encrypted. Otherwise encrypted communication between the objects is not possible.
In the overview of communication objects in the ETS project, secured objects can be recognized
by a shield symbol:
A separate key is automatically generated by the ETS for each secured group address. These
keys can also be checked in the ETS panel Reports –Project Security. To enable all devices to
communicate with a secure group address, the keys must be known to all. Therefore a download
must be made into all devices that use this group address when a key is created or changed. A key
is changed by the ETS e.g. when the encryption of a group address is switched off and on again.
