Copying a single file
U
Move the highlight to the file you wish to copy.
U Press the COPY soft key to select the copying
function.
U Enter the name of the destination file and confirm your
entry with the ENT key or EXECUTE soft key: The
TNC copies the file into the active directory. The
original file is retained, or
U Press the PARALLEL EXECUTE soft key to copy the
file in the background. Copying in the background
permits you to continue working while the TNC is
copying. This can be useful if you are copying very
large files that take a long time. While the TNC is
copying in the background you can press the INFO
PARALLEL EXECUTE soft key (under MORE
FUNCTIONS, second soft-key row) to check the
progress of copying.
Copying a table
If you are copying tables, you can overwrite individual lines or columns
in the target table with the REPLACE FIELDS soft key. Prerequisites:
n
The target table must exist.
n
The file to be copied must only contain the columns or lines you
want to replace.
Example
With a tool presetter you have measured the length and radius of 10
new tools. The tool presetter then generates the tool table TOOL.T
with 10 lines (for the 10 tools) and the columns
n
Tool number (column T )
n
Tool length (column L )
n
Tool radius (column R )
Copy this file to a directory other than the one containing the previous
TOOL.T. If you wish to copy this file over the existing table using the
TNC file management, the TNC asks if you wish to overwrite the
existing TOOL.T tool table:
U If you press the YES soft key, the TNC will completely overwrite the
current TOOL.T tool table. After this copying process the new
TOOL.T table consists of 10 lines. The only remaining columns in
the table are tool number, tool length and tool radius.
U
Or, if you press the REPLACE FIELDS soft key, the TNC merely
overwrites the first 10 lines of the columns number, length and
radius in the TOOL.T file. The TNC does not change the data in the
other lines and columns.
The REPLACE FIELDS soft key does not appear when you
want to overwrite the table in the TNC with an external
data transfer software, such as TNCremoNT. Copy the
externally created file into a different directory, and then
copy the desired fields with the TNC file management.
