Define device write protection code
Navigation Setup → Advanced setup → Administration → Define device write protection code
Expert → System → Define device write protection code
Description Sets a write protection code for the device.
If the code is programmed into the device firmware it is saved in the device and the
operating tool displays the value 0 so that the defined write protection code is not
openly displayed for viewing.
User entry 0 to 9 999
Factory setting 0
If the device is delivered with this factory setting the device write protection is not
active.
Additional information • Activating device write protection: To do so, enter a value in the Enter access code
parameter that does not correspond to the write protection code defined here.
• Deactivating device write protection: If device write protection is activated, enter the
defined write protection code in the Enter access code parameter.
• Once the device has been reset to the factory setting or the order configuration, the
defined write protection code is no longer valid. The code adopts the factory setting (=
0).
•
Hardware write protection (DIP switches) is active:
– Hardware write protection has priority over the software write protection described
here.
– No value can be entered in the Enter access code parameter. The parameter is a read
only parameter.
– Device write protection via software can only be defined and activated if hardware
write protection via the DIP switches is disabled .→  23
If the write protection code has been forgotten, it can be deleted or overwritten by
the service organization.
