Bluetooth radio interface

Devices with a Bluetooth radio interface are protected against un-
wanted access from outside. This means that only authorized persons
can receive measured and status values and change device settings
via this interface.
Information:
If no Bluetooth connection to the device should be possible, Bluetooth
communication can be deactivated. Access via app or DTM is thus no
longer possible. The Bluetooth function can be deactivated/activated
in the menu item "Extended functions" under "Access protection -
Bluetooth communication".
A Bluetooth access code is required to establish Bluetooth com-
munication via the adjustment tool (smartphone/tablet/notebook).
This code must be entered once when Bluetooth communication is
established for the first time in the adjustment tool. It is then stored in
the adjustment tool and does not have to be entered again.
The Bluetooth access code is individual for each device. It is printed
on the device housing and is also supplied with the device in the infor-
mation sheet "PINs and Codes". It can be changed by the user after
the first connection has been established. If the Bluetooth access
code has not been entered correctly, a new entry can only be made
after a waiting period has elapsed. The waiting time increases with
each additional incorrect entry.
The emergency Bluetooth access code enables Bluetooth communi-
cation to be established in the event that the Bluetooth access code
is no longer known. It can't be changed. The emergency Bluetooth
access code can be found in information sheet "Access protection".
If this document is lost, the emergency Bluetooth access code can
be retrieved from your personal contact person after legitimation.
The storage and transmission of Bluetooth access codes is always
encrypted (SHA 256 algorithm).

Schutz der Parametrierung

Die Einstellungen (Parameter) des Gerätes können gegen unerwün-
schte Veränderungen geschützt werden. Im Auslieferungszustand
ist der Parameterschutz deaktiviert, es können alle Einstellungen
vorgenommen werden.
Zum Schutz der Parametrierung kann das Gerät vom Anwender mit
Hilfe eines frei wählbaren Gerätecodes gesperrt werden. Die Einstel-
lungen (Parameter) können danach nur noch ausgelesen, aber nicht
mehr geändert werden. Der Gerätecode wird ebenfalls im Bedientool
gespeichert. Er muss jedoch im Unterschied zum Bluetooth-Zugang-
scode für jedes Entsperren neu eingegeben werden. Bei Benutzung
der Bedien-App bzw. des DTM wird dann der gespeicherte Geräte-
code dem Anwender zum Entsperren vorgeschlagen.
