Data backup
We recommend saving newly written programs and files on a PC at
regular intervals.
The TNCremoNT data transmission freeware from HEIDENHAIN is a
simple and convenient method for backing up data stored on the TNC.
You additionally need a data medium on which all machine-specific
data, such as the PLC program, machine parameters, etc., are stored.
Ask your machine manufacturer for assistance, if necessary.
Saving the contents of the entire hard disk (> 2 GB) can
take up to several hours. In this case, it is a good idea to
save the data outside of work hours, e.g. during the night.
Depending on operating conditions (e.g., vibration load),
hard disks generally have a higher failure rate after three to
five years of service. HEIDENHAIN therefore
recommends having the hard disk inspected after three to
five years.
