Data backup

Application

If you create or modify files on the control, then you should back up these files periodically.

Description of function

With the functions NC/PLC Backup and NC/PLC Restore you can create back-up files for specific directories or even an entire drive, and restore them as needed. You should store these backup files on an external storage medium.

Backup and restore

  • You have the following options for transferring files from the control:
  • TNCremo
  • With TNCremo you can transfer files from the control to a computer.

    PC software for data transfer

  • External drive
  • You can transfer files from the control directly to an external drive.

    Network drives on the control

  • External data carriers
  • You can back-up files to external data carriers or use external data carriers to transfer the files.

    USB devices

Notes

  • You should back-up all machine-specific data, such as the PLC program or machine parameters. Consult your machine manufacturer about this.
  • You must transmit files with the extensions PDF, XLS, ZIP, BMP, GIF, JPG and PNG in binary format from the PC to the control's hard disk.
  • Backing up all files of the internal memory can take several hours. If required, perform the backup during a time when you don't need the machine.
  • Periodically delete files that are no longer required. This ensures that the control has enough memory available for system files, such as the tool table.
  • HEIDENHAIN recommends having the hard disk inspected after three to five years. After this time, and depending on the operating conditions (e.g., vibration loads), you must expect increased failure rates.
