Pre-register
- You have at least the portal role 'Tenant Site Viewer' and are logged onto the portal.
- In the primary navigation, go to "Administration".
- In secondary navigation, go to "Pre-register".
- Tap or scan the activation key from the controller and enter the code in the "Activation key" field (comma separated or one per line)".
Multiple activation keys must be comma separated or entered one per line. - Click "Activate multiple sites".
- The per-activated controllers are per-registered for your area (tenant) and are in the menu "Administration > Plants" in the "Unassigned" tab.

The pre-registration of a controller is only valid for assigning the plant to a Sub-Tenant within its own Main-Tenant. Pre-registration for a plant activation in another Main-Tenant is not possible.
