SINUMERIK License Key

Basic information on license keys
If a license is required for a product, the purchaser receives a CoL (Certificate of License) with
the purchase of the license as proof of the right to use this product together with a
corresponding license key as 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 particular
SD card is also only valid on this SD card and is rejected as invalid on another SD 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 SD card
The SD 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 SD card thus represents the identity of a SINUMERIK control. For this reason, assigning
licenses to a control always occurs using the hardware serial number.
This has the advantage that the SD card can be inserted into a replacement MCU in the event
of failure of the MCU and all data is retained.
