Activate and Unactivate a License
The controller acts as a license proxy on behalf of agents. This means that only the controller requires Internet access to the Inductive Automation licensing servers. Whenever you use the License Management page or a Gateway task to assign, update or unactivate a license, the controller will request system information from the agent and forward the information to the licensing servers. If performing an activation, the activation data is sent back to the agent after the data is received from the licensing servers.
You can preload a list of license keys in the controller. After the license list is loaded, you can individually assign licenses to agents, or assign all free licenses to agents in one step via the Activate License task.
- To preload a license list, navigate to the Enterprise Administration > License Management page, look for the blue arrow, and click the “Add Licenses" link.
- Enter the license keys. Use commas to separate the licenses. The formatting is shown below:
- Click the Add button to save preloaded licenses.
You can remove unused licenses from the License Management page, but only if the license is not currently assigned to any agent. If you want to delete an assigned license, click the “unactivate” link on the right side of the license. After the Assigned Agent field changes to “Unassigned,” you can delete the license.
