You need empty Simatic SD card - only the simatic card works, it cannot be formatted in Windows (needs original format of files inside).
1. Insert card
2. Power ON cpu, wait until LED finish blinking
3. Remove card while CPU is ON
4. Power OFF, ON the cpu

The only way to do it - it will copy the program with password to the card. CPU will be empty after it
