10.8 Protecting settings from unauthorized access
The following write protection options exist in order to protect the configuration of the
measuring device from unintentional modification:
• Protect access to parameters via access code →  125
• Protect access to local operation via key locking →  60
• Protect access to measuring device via write protection switch →  126
• Protect access to parameters via startup configuration →  82
10.8.1 Write protection via access code
The effects of the user-specific access code are as follows:
• Via local operation, the parameters for the measuring device configuration are write-
protected and their values can no longer be changed.
• Device access is protected via the Web browser, as are the parameters for the measuring
device configuration.
• Device access is protected via FieldCare or DeviceCare (via CDI-RJ45 service interface), as
are the parameters for the measuring device configuration.
Defining the access code via local display
1. Navigate to the Define access code parameter (→  121).
2. Define a max. 16-digit character string comprising numbers, letters and special
characters as the access code.
3. Enter the access code again in the Confirm access code parameter (→  121) to
confirm the code.
 The -symbol appears in front of all write-protected parameters.
The device automatically locks the write-protected parameters again if a key is not pressed
for 10 minutes in the navigation and editing view. The device locks the write-protected
parameters automatically after 60 s if the user skips back to the operational display mode
from the navigation and editing view.
• If parameter write protection is activated via an access code, it can also only be
deactivated via this access code →  59.
• The user role with which the user is currently logged on via the local display
→  59 is indicated by the Access status parameter. Navigation path: Operation
