After activating the license on the device, the license should be backed up in case the SD/OS image needs to be restored in the future.

A soft-license can only be restored on the same device and not transferred to another. Alternatively, a license can be installed on a CODESYS dongle that can be used on any Raspberry Pi's.

TO BACK UP A LICENSE FILE

There are two ways to do this:

  1. Back up from the device via the CODESYS file manager 
    After establishing a connection to the device,
    1. Select the Files tab of the Device window
    2. Choose a location to save the file in your PC or an external drive
    3. Click on the Refresh button on the Runtime side
    4. Select the "CMLicenseNew.WibuCmRaU" file in the Runtime's file system
    5. Click on the "<<" button




  2. Only when using CODESYS >= 3.5 SP13: There should be a back up already on the PC where the license was activated from
    If the license was originally activated using CODESYS V3.5 SP13 or newer, the license backup file can be found under: "C:\ProgramData\CODESYS\Licenses\<license ticket number>" (there will be a folder for every license ticket)
    The license file will have the following naming format: "<Hardware serial number of the device>.WibuCmRau". For example:

TO RESTORE A LICENSE

There are two ways to do this:

If you are using an image or another license had already been activated on the device, delete the cmact_license folder from the Runtime's file system and restart the device before proceeding to restore the license.
