Parameters that can be changed when know-how protection is active
In spite of active know-how protection, certain parameters can be changed and read. The list
of these parameters can be found in the SINAMICS DCM List Manual in Chapter
"Parameters for write protection and know-how protection", Section "Parameters with
KHP_WRITE_NO_LOCK".
Parameters that can be read when know-how protection is active
In spite of know-how protection being active, additional parameters can be read, but are
locked against changes. The list of these parameters can be found in the SINAMICS DCM
List Manual in Chapter "Parameters for write protection and know-how protection", in Section
"Parameters with KHP_ACTIVE_READ".
Note
Password check for know-how protection
Please note that if the Windows language settings are changed, after activating know-how
protection, errors can occur when subsequently checking the password. If you use language-
specific special characters, you must ensure that the same language setting is active on the
computer for subsequent entry of the password.
Note
Data security of the memory card
After setting up and activating the know-how protection, for encrypted data backup on the
memory card, previously backed up, non-encrypted data of the SINAMICS firmware will be
deleted. This is the standard deletion procedure, in which only the entries on the memory
card are deleted. The data itself is still available and can be reconstructed.
To ensure know-how protection, we recommend the use of a new empty memory card. If you
cannot obtain a new memory card in the short term, you should delete all safety-related data
on the current memory card.
To completely delete your previous data on the memory card, you must reliably delete this
data using a suitable PC tool before activating know-how protection. The data is located on
the memory card in the "\\USER\SINAMICS\DATA" directory.
Note
Diagnostics under know-how protection
If service or diagnostics is to be performed when know-how protection is active, then
Siemens can only provide support in collaboration with the OEM partner.
