The license is a critical component of the DEP Power Platform. Without a valid license, the platform runtime will not start. Therefore, it is essential to ensure a valid license is in place before launching the runtime.

​
Request License

If you do not have a license, or if your current license is about to expire, contact the Power Platform support team to request a license. An expired license will cause the Power Platform controller to shut down, leaving the system unusable and uncontrollable. To avoid downtime, ensure that your license is renewed before it expires. When requesting a license, you will need to provide the controller UUID. This ensures that the generated license is securely tied to your specific controller and cannot be used on any other device.

​
Retrieve Controller UUID

1

Login to the WBM

Login to the WBM

Login to the Web-Based Management (WBM) interface of the Power Platform controller.
2

Navigate to the Configuration Tab

Copy Controller UUID

Copy the controller UUID from the PLCnext Store page, under System Information.

For license requests or updates, please reach out to the support team at [email protected]. Make sure to include the controller UUID in your request.

​
Upload License File

Once you have obtained a valid license, it must be uploaded to the Power Platform controller to enable the runtime. The license file is named license.txt and must be placed in the following directory on the controller: 
/opt/plcnext/appshome/data/60002172000969
There are multiple ways to upload the license file:

​
Using SCP (Secure Copy)

1

Open Terminal

Open a terminal on your local machine.
2

Copy License File

Use the scp command to copy the license file to the controller:
scp /path/to/license.txt admin@<controller_ip>:/opt/plcnext/appshome/data/60002172000969/
  • Replace /path/to/license.txt with the path to your local license file.
  • Replace controller_ip with the IP address of your controller.
  • Enter the admin password when prompted.
3

Verify File Upload

Verify the file has been uploaded by connecting to the controller via SSH and running:
ls -l /opt/plcnext/appshome/data/60002172000969

​
Using FileZilla

1

Open FileZilla

Open FileZilla (or another SFTP client) on your local machine.
2

Other Methods

Any method that allows transferring files over SSH or SFTP (e.g., WinSCP, rsync) can be used, as long as the license ends up in: /opt/plcnext/appshome/data/60002172000969.

​

Verifying the License

After uploading and rebooting the controller, you should verify that the license file has been correctly recognized.
1

Connect to Controller

Open License Log File

Open the license.log file to check for the license status:
nano license.log
If the license is valid, the log should contain a message indicating that the license is valid and successfully loaded.
If the log reports an error (e.g., license expired, invalid, or missing), double-check that the file is in the correct location and named license.txt, then reboot the controller again.If the error persists, contact the support team at [email protected] and provide the license.log file for further assistance.
