Maintenance
If an incorrect access code is entered, the user obtains the access rights of the Operator
role.
The user role with which the user is currently logged on is indicated by the Access
status display parameter (if operating via the local display) or the Access status
tooling parameter (if operating via an operating tool).
8.2.3 Data access - Security
Write protection via access code
Using the device-specific access code, the parameters for the measuring instrument
configuration are write-protected and their values can no longer be changed via local
operation.
Defining the access code via the local display
1. Navigate to: Setup → Advanced setup → Administration → Define access code
→ Define access code
2. Define a max. 4-digit numeric code as an access code.
3. Repeat the numeric code in the Confirm access code parameter to confirm it.
 The -symbol appears in front of all write-protected parameters.
Defining the access code via operating tool (e.g. FieldCare)
1. Navigate to: Setup → Advanced setup → Administration → Define access code
2. Define a max. 4-digit numeric code as an access code.
 Write protection is active.
Parameters that can always be changed
The write protection does not include certain parameters that do not affect the
measurement. Despite the defined access code, these parameters can always be modified
even if the other parameters are locked.
The device automatically locks the write-protected parameters again if a key is not pressed
for 10 minutes in the navigation and editing view. If the user goes from the navigation and
editing mode back to the measured value display mode, the device automatically locks the
write-protected parameters after 60 s.
• If write access is activated via an access code, it can be only be deactivated again via
this access code.
• In the "Description of Device Parameters" documents, each write-protected
parameter is identified with the -symbol.
Disabling write protection via access code
If the  symbol appears in front of a parameter on the local display, the parameter is
write-protected by a device-specific access code and its value cannot currently be changed
via the local display.
