Buffering up to 256 telegrams per tunnel (2048 in total) in the device on the IP side
Buffering up to 1024 telegrams for telegrams from IP to TP
ETS Parameter
Terms
Encryption, encrypted If devices send data information via the TP bus or IP network, they are
generally readable by third parties. These only require access to the TP bus or IP network for
reading. Encryption of the data in this context means that the contents of the telegrams are no
longer to be interpreted if the encryption parameters (for example passwords) are unknown.
Key, Key Parameter A series of numbers known only to the ETS project. These numbers are
used to transform the data in both directions: encryption and decryption.
FDSK (Factory Default Setup Key) The initial factory key. This key is used when commission-
ing the initial programming. A new key is loaded into the device, whereby this process is en-
crypted with the FDSK. The FDSK key is then no longer valid. It is reactivated only when reset-
ting to factory settings.
Backbone For IP routers, this is always the IP network.
Multicast An IP address in the network over which all the routers of a backbone communicate.
Tunnel connections do not need this address. Multicast connections are always established with
the UDP protocol. Unlike TCP communication, an UDP telegram can always be lost. This is e.g.
for WLAN connections very likely. Therefore, the routing backbone should always be realized
with an Ethernet cable connection, as this is almost 100% transmission safe.
Backbonekey The routing protocol communicates in secure mode with encrypted telegrams.
The key for encryption must be the same for all participants and is loaded into the device. The
ETS generates the necessary backbone key on its own.
Tunnelling A KNX point-to-point connection on the TCP / IP network, which is established with
UDP or TCP protocol. Tunneling communication is reliable and has incorporated a link layer for
that purpose. Therefore independent of the ethernet connection, e.g. Cable or WLAN, and re-
gardless of the TCP / IP protocol (UDP or TCP), no data is lost. With UDP, however, the restric-
tion is that the data link layer works with a one-second timeout. For Enertex devices, this timeout
can be adjusted in the advanced setup.
Telnet A simple TCP server on port 23 that enables direct text-based communication with the IP
device. Telnet is a de facto standard used at the window level, e.g. addressed with "Putty".
Secure Mode If the device is parameterized via the ETS so that the communication is only en-
crypted, this is referred to as secure mode.
Plain Mode If the device is parameterized via the ETS so that the communication is only unen-
crypted, this is called unsecured mode.
ETS 5.6.6 and ETS 5.7.0
Version requirements
For error-free operation of the devices in secure mode, ETS 5.7.x or higher is required.
In plain mode, the device can basically be programmed as of ETS 5.6.6. Although the secure
mode can be parameterized, it is not fully implemented in this version. If the device is therefore
to be operated secure, we recommend working with version 5.7 or higher.
Special behavior
If you program the individual address in the ETS 5.6.6 with its own and a tunnel connection, the
