Replacing a Control Unit with active know-how protection

Replacing devices with know-how protection without copy protection
In the case of know-how protection without copy protection, the inverter settings can be
transferred to another inverter using a memory card.
Replacing devices with know-how protection with copy protection
The know-how protection with copy protection hides the inverter settings and also prevents
the duplication of the inverter settings.
If the inverter settings can neither be copied nor forwarded, a recommissioning is required
after inverter replacement.
To avoid the recommissioning, you must use a Siemens memory card, and the machine
manufacturer must have an identical prototype machine that it uses as sample.
There are two options for replacing the device:
Option 1: The machine manufacturer only knows the serial number of the new inverter
1. The end customer provides the machine manufacturer with the following information:
– For which machine must the inverter be replaced?
– What is the serial number (r7758) of the new inverter?
2. The machine manufacturer performs the following steps online on the prototype machine:
– Deactivating know-how protection
– Enter the serial number of the new inverter in p7759.
– Enter the serial number of the inserted memory card as reference serial number in
– Activate know-how protection with copy protection. "Copy RAM to ROM" must be
– Write the configuration with p0971 = 1 to the memory card.
– Send the memory card to the end customer.
3. The end customer inserts the memory card and switches on the power supply for the
inverter.
When powering up, the inverter checks the serial numbers of the card and when there is a
match, the inverter goes into the "ready to start" state.
If the numbers do not match, then the inverter signals fault F13100 (no valid memory card).
