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:
- Backup the license update file CMLicenseNew.WibuCmRaU
- 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
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.
