Memory Card Copy Protection - Siemens SINAMICS G130 Operating Instructions Manual

Note
Changing parameter p7763
After parameter p7763 has been changed, a "Load to PG" must be realized so that the index
field of parameter p7764 is adapted.
In the factory setting, the exception list of the Control Unit consists of one parameter (p7763
= 1). p7766 (password input) is entered into parameter p7764[0] of the Control Unit; this
means that when know-how protection is activated, the password for deactivation can be
entered.
Note
Absolute know-how protection
If parameter p7766 is removed from the exception list and know-how protection is activated,
then a password can no longer be entered. This means that know-how protection can no
longer be deactivated!
In this case, the drive can only be accessed by restoring the factory settings.
9.2.21.6

Memory card copy protection

Using the memory card copy protection function, it can be ensured that the encrypted data
saved on the memory card (parameter and DCC data) cannot be copied to another memory
card where they are then subsequently used.
The memory card copy protection can be activated when activating the know-how protection
via STARTER.
When know-how protection is activated and the memory card copy protection is activated,
data (parameters and DCC) is encrypted, taking into account the serial number of the
memory card (r7843) and the Control Unit (r7758).
When the drive unit is powered up, the serial numbers saved on the memory card and the
Control Unit are compared to the actual serial numbers. If these serial numbers do not
match, then fault F13100 is output and the device can no longer be operated. The individual
cause can be determined by evaluating the default value.
9.2.21.7 Replacing devices for know-how protection with copy protection
When transferring configuration data with know-how protection and memory card copy
protection between machine manufacturers (OEMs) and end customers, it may be
necessary to replace a damaged memory card or a defective Control Unit.
For this particular case, there is a sequence which is then applied when transferring data
between the machine manufacturer (OEM) and end customer.
