Before licensing each controller, you should license your PC to run the software. This PC may be your Supervisor PC, or, if you do not require a Supervisor, this is usually a laptop temporarily connected to the controller or to the network that also serves the controller.

Your purchase of the software starts a license file for the PC that will serve as your Supervisor PC on the licensing server. This unbound license contains a key (a hexadecimal number). Upon fulfillment of an order, the licensing server sends this key to you by email.

When you install the software on the PC, the installation program calculates the host ID for the PC. At the end of installation, an online form that contains the calculated host ID automatically opens. You enter the license key and item number you received in the email along with your name and email address. Using this self-serve process, the licensing server immediately finishes (binds) your host ID to your license key and emails the completed license file back to you as an attachment.
