Protecting settings from unauthorized access

The following options exist for protecting the configuration of the measuring device from
unintentional modification after commissioning:
• Write protection via access code (® ä 33)
• Write protection via lock switch (® ä 33)
• Write protection via keypad lock (® ä 29)
9.6.1 Write protection via access code
Using the customer-specific access code, the parameters for the measuring device configuration
are write-protected and their values can no longer be changed via local operation.
Define access code
1. Navigating to the "Define access code" parameter: Setup ® Advanced setup ® Def. access
code
2. Define a max. 4-digit numeric code as an access code.
à The -symbol appears in front of all write-protected parameters.
If no key is pressed for 10 minutes in the navigation and editing mode, the device automatically
locks the write-protected parameters. 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 access code, it can be also be deactivated only via the access
code (® ä 29).
9.6.2 Write protection via lock 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 values of the parameters are still visible, but can no longer be changed (except for Contrast
display), either via the local display, the service interface (CDI) or HART protocol.
