5 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.

6 ETS database
The ETS5 database (for ETS 5.7 or newer) can be downloaded from the product website of the
KNX IO 510.1 secure (2O) (www.weinzierl.de) or from the ETS online catalogue.
The KNX IO 510.1 secure (2O) 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.
6.1 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 9/30
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 10/30
In the ETS project in the properties of the device, secure commissioning can be activated and the
device certificate can be added:
6.2 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:

© 2022 WEINZIERL ENGINEERING GmbH Seite 11/30
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.

6.3 Description
This page shows the device description and the corresponding connection diagram.
6.4 General settings
Device name (30 characters)
An arbitrary name can be assigned for the KNX IO 510.1 secure (2O). The device name should be
meaningful, e.g. “Living Room”. This helps the clarity of the ETS project.

© 2022 WEINZIERL ENGINEERING GmbH Seite 13/30
Send delay after bus power return
A send delay of telegrams after the return of the bus voltage can be set via this parameter. In this
case, telegrams from the device are sent to the KNX bus in a delayed manner by the set time. This
results in a reduction of the bus load at a bus power return. Other functions such as receiving
telegrams of switching operations of the actuator are not affected by this parameter.
Prog. mode on device front
In addition to the normal programming button ❸the device allows activating the programming
mode on the device front without opening the switchboard cover. The programming mode can be
activated and deactivated via pressing simultaneously both buttons ❼and ❽.
This feature can be enabled and disabled via the parameter “Prog. mode on device front”. The
recessed programming button ❸(next to the Programming LED ❷) is always enabled and not
influenced by this parameter.
Manual operation on device
This parameter is used to configure the manual operation on the device. The manual operation
mode can be disabled or activated (with or without time limitation). The time limit defines the
duration until the automatic return from the manual operation mode back into the normal operating
mode.
The device is in normal operating mode when the manual control is not active. In the manual
operating mode, received switching telegrams are ignored. When the manual operation mode is
terminated (after expiry of the time limit or manually), the last state of the outputs remains, until a
new switching telegram is received again.
The following options are selectable:
▪Disabled
▪Enabled with time limit 1 min
▪Enabled with time limit 10 min
▪Enabled with time limit 30 min
▪Enabled without time limit
Heartbeat

Lock function (for function “Universal output”, “On/Off delay”or “Staircase function”)
With this parameter the lock function can be enabled. If this functionality is activated, the
associated group objects as well as the parameter page “Actuator A / B: Lock function” are
displayed for further configuration. If the lock has been activated via the group object “Lock”, the
received switching telegrams are not executed.
In addition to the lock object, there is also a priority object, which can be switched independently of
the lock. Thus, it is possible to set an output state without affecting other functions.

In addition to the lock object, there is also a priority object, which can be used to set a control value
independently of the lock. Thus, it is possible to set an output PWM without affecting other
functions.
When the lock is ended, the last received value (not priority object) is represented as PWM at the
output.

Example of the priority object:
In the case of events in public buildings or in restaurants, the normal operation can be set into an
inoperative state by the lock group object. Thus it is possible to lock during the lecture or concert,
switches that are accessible to unauthorized persons, in order to prevent unmeant switching.
Nevertheless, the individual lamps can controlled by use of the priority object without canceling the
lock.
