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 (2GB) 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 TNC 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.
