Know-how protection
9.3.22.1
Description
The know-how protection is used, for example, so that machine manufacturers can encrypt
their configuration know-how and protect it against changes and copying.
For know-how protection, a password is required; saved data is encrypted.
When know-how protection is activated, most of the setting parameters cannot be changed
and cannot be read out. The display parameters are shown unchanged. The contents of
screen forms in STARTER are not displayed.
Know-how protection can be combined with copy protection.
Characteristics when know-how protection is activated
● Except for a small number of system parameters and the parameters specified in an
exception list, all other parameters are locked.
● The values of these parameters are not visible in the expert list and so cannot be
changed. The text "know-how protected" appears instead of the parameter values.
● Know-how protected parameters can be hidden in the expert list. This requires that the
"not know-how protected" filter is set in the "Online value" column.
● The values of display parameters remain visible.
● The contents of screen forms are not displayed when know-how protection is active.
● Know-how protection can be combined with copy protection.
● The same know-how protection is used for scripts.
● The drive unit as well as the drive objects and DCC charts therein can be displayed as
inconsistent.
Know-how protection with and without copy protection.
To protect the drive unit settings against unauthorized copying, in addition to know-how
protection, you can also activate copy protection.
Know-how protection without copy protection is possible with or without memory card.
Know-how protection with copy protection is only possible with a Siemens memory card.
Know-how protection without copy protection
The drive unit can be operated with or without a memory card. The drive unit settings can be
transferred to other drive units using a memory card, an operator panel or STARTER.
