4.1 SINUMERIK License Key
SD card as a spare part
If the SD card of a SINUMERIK control is replaced, for example, because of defective
hardware, the license key loses its validity and the system is no longer operational.
In case of defective hardware of the SD card, contact the "Technical Support". They will then
send you a new license key without delay. The following data is required:
● Hardware serial number of the defective SD card
● Hardware serial number of the new SD card
Note
Only SD cards can be used that were released as a spare part, as only these are known to
the license database.
Determining the hardware serial number
The hardware serial number is a permanent part of the SD card. It is used to identify a control
system uniquely. The hardware serial number can be determined by:
● Certificate of License (CoL)
● SINUMERIK user interface
● Label on the CompactFlash card
Note
Hardware serial number and CoL
The hardware serial number is located only on a CoL of the system software or if the license
was ordered bundled, in other words the system software came together with options.
