Data backup
We recommend saving newly written programs and files on 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
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.
Take the time occasionally to delete any unneeded
files so that the TNC always has enough memory
space for system files (such as the tool table).
