After the activation of the license on the device, the license should be backed up so that it is available for a re-installation of the SD/OS image.

A soft license can only be restored on the same Raspberry Pi and cannot be transferred to another.

Alternatively, there is a possibility to use a dongle that can be used on any Raspberry Pi.

Backing up a license

There are two possibilities to do this:

  1. Backup the license update file CMLicenseNew.WibuCmRaU
  2. Backup the file 3SLicenseInfo.tar to the backup directory (/backup)

Both possibilities can be used independently of each other (alternatives to backup methods)

Backing up the license update file CMLicenseNew.WibuCmRau via the CODESYS file manager

Backing up the file 3SLicenseInfo.tar from the backup directory (/backup) via the CODESYS file manager

Restoring the license on a reinstalled device

Restoring the license from the file CMLicenseNew.WibuCmRau

As of SP13:

 


As of SP13, there is only one location where the License Manager is called.
This is the menu item Tools\License Manager in the main menu of the CODESYS development environment.






Up to SP13:

Restoring the license from the file 3SLicenseInfo.tar via the CODESYS file manager

Copy the file 3SLicenseInfo.tar to the directory restore and restart the PLC.
