2.7 Connexion KNX IP secure
KNX Secure devices are able to encrypt and decrypt telegrams, thus adding an extra level of security to a KNX
installation. This level of security can be used both during the commissioning of KNX installations as for KNX
installations at runtime.
There are two types of encryption:
-
KNX IP Secure : Telegrams are entirely encrypted and applied only to the KNX IP medium. This encryption
must be used for KNX installations using an external IP network such as the Internet.
-
KNX Data Secure : Telegrams are partly encrypted and applied to any KNX communication medium. This
encryption can be used for the KNX IP medium, but only for the part of the KNX installation that is not exposed
to an external IP network.
The procedure below describes how to set up KNX IP Secure with the domovea server.
Before setting up the ETS project, the following conditions must be fulfilled:
-
The ETS software must have at least version 5.7.4 (v1093).
-
The first connection to the KNX bus must be made in a local network via the domovea server.
Installing the application:
-
Download the KNX product data file (knxprod) depending on the version of the domovea server
▪
PS_TJA470_V101_T1.KNXPROD
for version TJA470
▪
PS_TJA670_V102_T1.KNXPROD
for version TJA670
-
Start ETS
-
In the
Bus
section, select the interface corresponding to the local server.
-
Open the concerned ETS project and select the server version from the product catalogue.
-
Installing the domovea server in the project.
If the project is not yet secured at that time, ETS will ask to enter a new password.
-
Add the KNX certificate of the device using the QR code or manually.
the KNX certificate of the device can be found in the
Interface
section of the domovea server.
-
Enable
Secure Commissioning
in the device properties in the
Settings
tab.
-
Perform a full download of the device.
