License Keys
The license key is the technical representation (an electronic "license stamp") of a license to use
software.
SIEMENS AG issues a license key for all of its software that is protected by a license. When the
computer has been started, such software can only be used in accordance with the applicable
license and terms of use after the presence of a valid license key has been verified.
Notes
• You can use the standard software without a license key to familiarize yourself with the user interface and
functions.
• However, a license is required and necessary for full, unrestricted use of the STEP 7 software in
accordance with the license agreement
• If you have not installed the license key, you will be prompted to do so at regular intervals.
License Keys can be stored and transferred among various types of storage devices as follows:
• On license key diskettes or USB memory stick
• On the local hard disk
• On network hard disk
If software products for which no license is available are installed, you can then determine which
license key is needed and order it as required.
For further information on obtaining and using license keys, please refer to the online help for the
Automation License Manager.
