CODESYS and the CODESYS the standard runtime systems (with version 3.5.8.0 and higher) support backing up application-specific files on the PLC. You can execute the required actions in the “Backup and Restore” tab of the generic device editor.

A backup consists of creating and saving a file in zip archive that contains the application-related files and an information file ‎meta.info‎. This backup file has the extension ‎TBF‎ (="Target Backup File") and can be saved in the local file system or on the PLC.

The following applies when restoring the software status from the backup file:

  • A dialog opens with a list of affected files on the PLC, and you can deactivate optional components.

  • We highly recommend to set the application to STOP mode for backup or restore. A dialog prompt will open to warn you about this.

  • The user interface is blocked when restoring to the PLC.

  • Existing files are overwritten without warning.

  • Existing boot applications are deactivated as soon as at least one new boot application is part of the restore.
