Data backup
We recommend saving newly written programs and files on a PC at
regular intervals.
HEIDENHAIN provides a backup function for this purpose in the data
transfer software TNCremoNT. Your machine tool builder can provide
you with a copy of TNCBACK.EXE.
You additionally need a data medium on which all machine-specific
data, such as the PLC program, machine parameters, etc., are stored.
Please contact your machine tool builder for more information on both
the backup program and the floppy disk.
