Device-specific IT security

The device offers a range of specific functions to support protective measures on the
operator' s side. These functions can be configured by the user and guarantee greater in-
operation safety if used correctly. The following list provides an overview of the most
important functions:
2.7.1

Access via the SmartBlue app

Two access levels (user roles) are defined for the device: the Operator user role and the
Maintenance user role. The Maintenance user role is the default setting.
If a user-specific access code is not defined (in the Enter access code parameter), the
default setting 0000 continues to apply and the Maintenance user role is automatically
enabled. The device' s configuration data are not write-protected and can be edited at all
times.
If a user-specific access code has been defined (in the Enter access code parameter), all the
parameters are write-protected and the device is accessed with the Operator user role. The
previously defined access code must first be entered again before the Maintenance user
role is enabled and all the parameters can be write-accessed.
2.7.2

Protecting access via hardware write protection

Write access to the device parameters via the operating tool can be disabled by means of a
write protection switch (DIP switch on the back of the local display). When hardware write
protection is enabled, only read access to the parameters is possible.
Hardware write protection is disabled when the device is delivered →  11.

 Information regarding the
write protection switch is
provided on the connection
nameplate in the connection
compartment cover.
Unlike parameter write protection via a user-specific access code, this allows write access
to the entire operating menu to be locked.
The parameter values are now read only and cannot be edited any more.
The following parameters can always be modified even if parameter write protection
is activated:
• Enter access code
• Contrast display
• Clientt ID
