the compact flash memory for the SINAMICS CU320 is provided in 2
version , basic and performance 1
the 'only' difference is a file called KEYS.TXT that enable the 'performance 1' feature.
This is an key file that I think is generated according the serial-number of the CF card
know everybody something about this
(kind of processor in CU , disassembler , key generator ....)
