Replacing devices during know-how protection

Replacing devices during know-how protection without copy protection
During know-how protection without copy protection, you can save the configuration settings
of the converter with the automatic upload (see Saving setting on memory card (Page 249))
on an empty memory card, and with the automatic download (see Transferring the setting
from the memory card (Page 251)) you can transfer these to another converter – and thus
replace devices or commission other converters.
Replacing devices for know-how protection with copy protection
The know-how protection with copy protection prevents the converter settings from being
copied and passed on. This function is predominantly used by machine manufacturers.
If know-how protection with copy protection is active, the converter cannot be replaced as
described in "Overview of how to replace an inverter (Page 267)".
However, to allow the converter to be replaced, it must be operated with a Siemens memory
card, and the machine manufacturer must have an identical machine that he uses as
sample.
There are two options for replacing the device:
Case 1: The machine manufacturer only knows the serial number of the new converter
Procedure:
1. The end customer provides the machine manufacturer with the following information:
SINAMICS G120C frequency converter

CAUTION
Take special care when creating the exception list!
If you remove p7766 from the exception list, you can no longer enter a password and
therefore no longer deactivate know-how protection. The only possibility to be able to
access the converter again is to reset the converter to the factory settings.
– For which machine must the converter be replaced?
– What is the serial number (r7758) of the new converter?
