9.8 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 →  122
• Protect access to local operation via key locking →  58
• Protect access to measuring device via write protection switch →  124
9.8.1 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 (→  112).
2. Define a max. 16-digit character string comprising numbers, letters and special
characters as the access code.
