Protection
To ensure only authorized persons are able to read and write data, it is
possible to protect:
- Access to pages
- Modification of fields
- Control via functional links
If an operator does not have authorization:
- Protected pages no longer appear in the list of pages
- Protected fields behave as if they had been configured as read-only
The password is entered via the "Password" system page. A navigation
link to the "Password" system page is required on one of the application
pages. (For more information about how system pages are displayed,
see section "6. System pages", Page 39).
There are three access levels: A, B and C.
These passwords are defined in XBT L100•. A password consists of four
alphanumeric characters (default value 1111).
