7.3.9 Access code and user roles
Meaning of the access code
An access code can be defined in order to distinguish between the following user roles:
User role Definition
Maintenance • Knows the access code.
• Has write access to all parameters (except service parameters).
Operator • Doesn't know the access code.
• Has write access to only a few parameters.
• The description of parameters states which role is needed at least for read and write
access to each parameter →  153.
• The current user role is indicated by the Access status display parameter.
• If the access code is "0000" , every user is in the Maintenance role. This is the
default setting on delivery of the device.
Defining an access code
1. Navigate to: Setup → Advanced setup → Administration → Define access code
→ Define access code
2. Enter the intended access code (max. 4 digits).
3. Repeat the same code in the
Confirm access code parameter.
 The user is in the Operator role. The -symbol appears in front of all write-
protected parameters.
Switching to the "Maintenance" role
If the -symbol appears on the local display in front of a parameter, the parameter is
write-protected because the user is in the Operator role. To switch to the Maintenance
role, proceed as follows:
1. Press .
 The input prompt for the access code appears.
2. Enter the access code.
 The user is in the Maintenance role. The -symbol in front of the parameters
disappears; all previously write-protected parameters are now re-enabled.
Switching back to the "Operator" role automatically
The user automatically switches back to the Operator role:
• if no key is pressed for 10 minutes in the navigation and editing mode.
• 60 s after going back from the navigation and editing mode to the standard view
(measured value display).
Switching back to the "Operator" role manually
1. Navigate to: Setup → Advanced setup → Enter access code
2. Enter any number other than the previously defined access code.
 The user is in the Operator role. The -symbol appears in front of all write-
protected parameters.
