CF Card and hardware serial numbers

The CF card (Compact Flash card) contains, in addition to the system and user software and
the retentive system and user data, that data relevant for the license management of
SINUMERIK software products of a control system:
● Hardware serial number
● License information including the License Key
The CF card thus represents the identity of a SINUMERIK control system. For this reason,
assigning licenses to a control system always occurs using the hardware serial number.
This has the advantage that the CF card can be slotted into a replacement NCU in the event
of failure and all data is retained.
Automation License Manager
Thus, the hardware serial number is always decisive during the transfer of license
information to a control system in Automation License Manager and not the set IP address of
the control system with which Automation License Manager is currently communicating.
Determining the hardware serial number
The hardware serial number is a permanent part of the CF card. It is used to identify a
control system uniquely. The hardware serial number can be determined by:
● CoL (Certificate of License) (see note)
● SINUMERIK user interface, e.g. HMI Advanced
● Printing on the CF card
● Display in the Automation License Manager as supplementary information for the
IBN CNC: NCK, PLC, drive

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.
