Copy protection
In conjunction with the copy protection, the converter settings can be coupled only to a
single, pre-defined hardware.
Know-how protection with copy protection is only possible using the recommended Siemens
card, see also Section: Technical data for CU230P-2 (Page 369)
List of exceptions

the customer may access.
If you remove the parameter for the password from the exception list, the know-how
protection can only be undone by reverting to the factory settings.
Actions that are possible during active know-how protection
● Restoring factory settings
● Acknowledging messages
● Displaying messages
● Show message history
● Reading out diagnostic buffer
● Switching to the control panel (complete control panel functionality: Fetch master control,

The individual parameters that are excluded from the know-how protection can be found in
the List Manual in Chapter "Parameters for write protection and protection of know-how".
