KNX USB interface stick
The requirements for communication between the
ETAtouch control system and the KNX installation bus
are:
• Software version X.49.0 or higher is installed on
the ETAtouch control panel
• ETAtouch control panel of the generation [BE-P2]
or [BE-P3]
A "KNX USB interface stick," which is connected to the
ETAtouch control system [BE-P], serves as the
interface for the KNX installation bus for the ETAtouch
control panel.
Fig. 2-1: KNX USB interface stick
Connect the KNX bus line to the USB interface stick.
The KNX polarity is marked on the housing with +/-;
see the graphic below.
Fig. 2-2: Correct KNX polarity
Further details on the KNX USB interface stick
can be found in the manufacturer's operating in-
structions in Chapter 4 "Appendix".
Plug the KNX USB interface stick into a free USB port
on the ETAtouch control panel. Use the supplied USB
extension for this.
Fig. 2-3: USB connections on the control panel [BE-P3]
Fig. 2-4: USB extension for KNX bus
The configuration is performed via the "ETS"
programming software (version 5 or higher) on a
laptop or PC. The possible parameters and communi-
cation objects from the ETAtouch control system are
listed in Chapter 3 "Adjustable parameters".
Establish a KNX connection to the ETAtouch
control system

4. The [Programming button] button must be
pressed to allow the KNX USB interface stick to be
identified. An address can then be assigned to the
USB interface stick using the "ETS" programming
software.
If the error symbol appears among the
symbols for USB and KNX (in the upper left
area), check whether both the USB interface stick
and the KNX bus line are connected correctly.
5. The assignment of the function blocks, e.g., hot
water tank [WW] to the KNX groups is performed
via the selection list for the respective function
block. Select the [Not used] setting for those
function blocks that are not required for KNX com-
munication.

6. Once the assignment has been made, close the
window. Following this, the ETAtouch control
system must be restarted to save and activate the
KNX connection.
The ETAtouch control system must be
restarted for all changes to the configuration
with the "ETS" programming software and
subsequent installation on the KNX USB interface
stick.

Adjustable parameters
3 Adjustable parameters
Parameters from the ETAtouch control system for communication via the KNX bus
The following applies to all parameters: If a value greater than 0 is set at [Transmit cyclical?], the ETAtouch control
system sends the values at the set interval. The value "0" deactivates the regular transmission of the values. It can
also be set for all parameters if there is a change in value (e.g., temperature change of 1°C), regardless of whether
these are transmitted or not. In the general settings, the ETAtouch control system can transmit the time and in
adjustable intervals.
The factory settings of the "flags" for the individual communication objects are listed in the following tables. The flags
can be adjusted as needed. The abbreviations mean the following:
• C = Communication (always set)
• R = Read
• W = Write
• T = Transmit
The R flag must be set to facilitate reading. The last value written into the object via the bus is read out. If no
(or no reasonable) value is output for a communication object, the setting [Transmit on change in value?] may
be deactivated in the "ETS" programming software, or [Transmit cyclical?] may be set to 0.
The ETAtouch control system must be restarted for all changes to the configuration with the "ETS"
programming software and subsequent installation on the KNX USB interface stick.

USB Suspend
Wenn der PC oder Laptop in den Ruhemodus wechselt, werden
auch angeschlossene USB-Geräte in den Ruhemodus versetzt,
um Energie zu sparen. Computer mit MS Windows® 8.1 oder
höher können auch im Normalbetrieb unbenutzte Peripheriege-
räte in den Standby-Modus setzen. Im Ruhe-Modus sind beide
LEDs der KNX USB Schnittstelle ausgeschaltet.
Werkseinstellungen
Ab Werk ist folgende Konfiguration voreingestellt:
Physikalische Adresse des Gerätes: 15.15.255
Schnittstelleneinstellungen in der ETS
In der ETS können Schnittstellen über das ETS Menü „Bus -
Schnittstellen“ ausgewählt und konfiguriert werden.
Nachdem das KNX USB Interface an den PC und den KNX Bus
angeschlossen wurde, erscheint automatisch in der ETS im
Menüpunkt „Bus“ unter „gefundene Schnittstellen“.
Durch Anklicken der gefundenen Schnittstelle wird diese als
aktuelle Schnittstelle ausgewählt. Auf der rechten Seite des ETS
Fensters erscheinen dann verbindungsspezifische Informationen
und Optionen.
Hier kann die physikalische Adresse des KNX USB Interfaces
geändert werden. Um zu überprüfen, ob die gewünschte physi-
kalische Adresse nicht bereits in der KNX Installation vorhanden
ist, kann die Schaltfläche „Adresse frei?“ betätigt werden.

ETS Datenbank
Die ETS Datenbank (für ETS 4.2 und höher) kann auf der Pro-
duktwebsite (www.weinzierl.de) heruntergeladen werden.
Der ETS-Eintrag ist nicht erforderlich, um die KNX USB-
Schnittstelle als Programmierschnittstelle zu verwenden. Es ist
nur ein Platzhalter, um alle installierten Geräte in der Topologie
zu zeigen.
ETS Parameterdialog
Das KNX USB Gerät hat keine Parametereinstellungen. Der
Parameterdialog zeigt nur eine Beschreibungsseite an.
Busmonitormodus
Die KNX USB Schnittstelle unterstützt den Busmonitormodus,
der auch mit der ETS verwendet werden. Im Busmonitormodus
wird der gesamte Verkehr auf dem KNX-Bus mit ACK-, NACK-
und BUSY-Zeichen angezeigt.
Schnittstellen im Busmonitormodus verhalten sich auf dem Bus
völlig passiv und können daher nicht gleichzeitig für andere
Operationen wie Download verwendet werden. Zur Überwa-
chung eines ETS-Downloads innerhalb derselben ETS kann der
Gruppenmonitor verwendet werden. Der Gruppenmonitor nutzt
die KNX USB-Schnittstelle im Normalbetrieb (Data Link Layer)
und kann parallel zu anderen Busoperationen verwendet wer-
den. Im Gruppenmonitor ist auch das Senden von Telegrammen
möglich.
Hinweis: im Gruppenmonitor-Modus werden physikalisch adres-
sierte Telegramme, die nicht die KNX USB-Schnittstelle adres-
sieren, nicht empfangen.
KNX Long Frames
Standard-KNX-Telegramme sind auf eine APDU-Länge von 15
begrenzt. Die APDU-Länge ist die Anzahl der Bytes der Nutzda-
ten. Ein Gruppentelegramm mit einem 14 Byte String (KNX
Datenpunkt Typ 16) ergibt eine APDU Länge von 15.
Um die Effizienz der KNX-Kommunikation vor allem für den
Download zu erhöhen, wurde ein erweitertes Format definiert. Es
kann verwendet werden, um längere Telegramme auf den Bus
zu senden. Um diese Funktion nutzen zu können, muss sie
unterstützt werden von
xder Software (ETS)
xdem Bus Interface (USB)
xallen dazwischen-liegenden Kopplern
xdem adressierten Gerät
Die ETS ab Version 5 kann automatisch erkennen, ob Long
Frames verwendet werden können und optimiert den Download
entsprechend.
Die maximale APDU-Länge der KNX USB-Schnittstelle, die von
der ETS verwendet wird, beträgt 55. Diese Länge wurde als
Anforderung für neue KNX-Systemgeräte spezifiziert. Eine
APDU-Länge von 55 ergibt die Gesamtlänge eines KNX-
Telegramms auf Twisted Pair von 64 Bytes und belegt den Bus
für ca. 90 ms.
Der Download ist deutlich schneller, wenn die USB-
Schnittstelle in der gleichen Linie wie das Zielgerät in-
stalliert ist. Mit jedem Linienkoppler dazwischen wird die
Downloadzeit länger.
Hinweise für Entwickler
Die KNX USB Kommunikation basiert auf dem HID/cEMI-
Protokoll entsprechend der KNX-Spezifikation. Um die KNX USB
Schnittstelle in eigene Anwendungen unter Windows oder Linux
zu integrieren, steht das Cross-Plattform SDK kDrive von Wein-
zierl zur Verfügung.
Neben der Telegrammschnittstelle über cEMI verfügt die KNX
USB Schnittstelle 332 über einen kompletten KNX Stack mit
Kommunikationsobjekten und BAOS Protokoll V2. So bietet das
Gerät die Möglichkeit, Geräte mit USB-Anschluss (z.B. Boards
mit embedded Linux) zu vollwertigen KNX-Geräte zu erweitern,
die sogar mit der ETS programmiert werden können.
Für weitere Informationen über diese Lösung und verfügbare
SDKs wenden Sie sich bitte an WEINZIERL.
