4.2.2 NC Program Transfer by Operating the NC
To transfer an NC program by operating the NC, you cannot specify the
directory path to a file on the personal computer on the NC. On the NC,
specify an NC program with the file name, file number, or NC program
number of the NC program.
NC program management associates the file name, file number, or NC
program number directed by the NC with a file stored on the personal
computer.
At this time, the file name, file number, or NC program number is used
as a key.
NC program management searches the files in the default directory for
the NC program to be transferred using the key. With
FOCAS2/Ethernet and the Data Server, however, the concepts of key
and relating files are not applicable.
There are restrictions on the method for specifying the file name, file
number, or NC program number and on available keys, depending on
the NC type and communication protocol.
See Appendix C, "EXAMPLES OF NC OPERATIONS" or CNC
Operator’s Manual for main methods for selecting an NC program by
operating the NC.
The following table lists restrictions on operations depending on the
communication function.
