adapt the project to the modified hardware.
Dependency: Refer to: p7765, p7766, p7767, p7768
Note: KHP: Know-How Protection
- the OEM may only change this parameter for the use case "Sending encrypted SINAMICS data".
- SINAMICS only evaluates this parameter when powering up from the encrypted "Load into file system..." output or
when powering up from the encrypted PS files. The evaluation is only made when know-how protection and memory
card copy protection have been activated.

Dependency: Refer to: p7761, p7765, p7766, p7767, p7768
Note: KHP: Know-How Protection
For bit 00:
Write protection can be activated/de-activated via p7761 on the Control Unit.
For bit 01:
The know-how protection can be activated by entering a password (p7766 ... p7768).
For bit 02:
If it has already been activated, know-how protection can be temporarily de-activated by entering the valid password
in p7766. In this case, bit 1 = 0 and bit 2 = 1 offset.
For bit 03:
Know-how protection cannot be de-activated, as p7766 is not entered in the OEM exception list (only the factory
setting is possible). This bit is only set if know-how protection is active (bit 1 = 1) and p7766 has not been entered in
the OEM exception list.
For bit 04:
When know-how protection has been activated, the contents of the memory card (parameter and DCC data) can be
additionally protected against being used with other memory cards/Control Units. This bit is only set if know-how
protection is active and p7765 bit 00 is set.
