Data backup
HEIDENHAIN recommends backing up new programs and files
created on the control to a PC at regular intervals.
The TNCremo data transmission freeware from HEIDENHAIN is a
simple and convenient method for backing up data stored on the
control.
You can also backup files directly from the control. Further
information: "Backup and restore", page 119
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 internal memory 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.
Take the time occasionally to delete any unneeded files
so that the control always has enough hard-disk space
for system files (such as the tool table).
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.
