SINUMERIK License Key

Basic information on license keys
If a license is required for a product, then with the purchase of the license the purchaser
receives a CoL as proof for the rights to use this product and a corresponding license key as to
the "technical representative" of this license. In conjunction with software products, the license
key usually must be available on the hardware on which the software product is executed.
Note
Trial license
A trial license supports "short-term use" of the software in a non-productive context, e.g. use for
testing and evaluation purposes; it can be transitioned into another license.
SINUMERIK license keys
Depending on the software product, there are license keys with different technical properties.
The essential properties of a SINUMERIK license key are:
● Hardware serial number
Via the hardware serial number contained in the SINUMERIK License Key, there is a direct
relationship between the License Key and the hardware on which it may be used. That
means a License Key that was generated for the hardware serial number of a certain
CompactFlash card is also only valid on this CompactFlash card and rejected as invalid on
another CompactFlash card.
● Total number of assigned licenses
A SINUMERIK license key not only refers to a single license, instead it is the "technical
representative" of all licenses that are assigned to the hardware at the time of its generation.
Content of the CompactFlash card
The CompactFlash card contains the system and user software, the retentive system and user
data, along with the data relevant for the license management of SINUMERIK software
products of a control system:
● Hardware serial number
● License information including the license key
The CompactFlash card thus represents the identity of a SINUMERIK controller. For this
reason, assigning licenses to a controller always occurs using the hardware serial number.
This has the advantage that the CompactFlash card can be inserted into a replacement NCU
in the event of failure and all data is retained.
