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.
You have the following options for transferring files from the control:
- TNCremo
With TNCremo you can transfer files from the control to a computer.
- External drive
You can transfer files from the control directly to an external drive.
- External data carriers
You can back-up files to external data carriers or use external data carriers to transfer the files.
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.
