A site license allows the use of Automation Studio by any number of users at a single company location. The users must be employed at the respective company site but can use Automation Studio regardless of their location (internationally active service technicians, for example). Licensing takes place via activation over the Internet. After one year, the license will automatically be extended an additional year and invoiced accordingly as long as the license has not been canceled before expiration.
