Know-how protection
Know-how protection
The know-how protection is used to encrypt configuring/engineering know-how, and protect it
against being changed or copied.
The settings of the converter are protected by a password.
If the password is lost, only default settings are possible.
The active know-how protection provides the following:
● All setting parameters are invisible.
● Parameters cannot be changed with a commissioning tool, e.g. operator panel or
STARTER.
● It is not possible to download the converter settings with the Starter or via a memory card
● It is not possible to use the trace function in the STARTER.
● Deleting the alarm history
● The STARTER dialog screens are disabled. The expert list in the STARTER contains
only display parameters.
In the case of active know-how protection, support by technical support personnel is only
possible with the consent of the machine manufacturer.
In conjunction with the copy protection, the converter settings can be coupled only to a
single, pre-defined hardware.
The know-how protection with copy protection is possible only with the recommended
Siemens memory card; also see Section: Components for assembling a frequency converter
(Page 21)
The active know-how protection permits an exception list for parameters to be defined that
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
