Commissioning

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 write access is activated via access code, it can be also be deactivated only via the
access code (→  32).
• The user role with which the user is currently logged on via the local display (→  32)
is indicated by the Access status display parameter. Navigation path: Display/
operation → Access status display
9.6.2 Write protection via write protection switch
Unlike write protection via user-specific access code, this allows write access to the entire
operating menu - other than the Contrast display parameter - to be locked.
The parameter values are now read only and cannot be edited any more (exception Contrast
display):
• Via local display
• Via service interface (CDI)
• Via HART protocol
