If the I/O channel (parameter No. 20) is set to 4, files on the memory card
can be referenced and various types of data such as part programs,
parameters, and offset data can be input and output in text file format by
using the memory card interface of the control unit.
The major functions are listed below.
⋅ Displaying a directory of stored files
The files stored on a memory card can be displayed on the directory
screen.
⋅ Searching for a file
A search is made for a file on a memory card and, if found, it is
displayed on the directory screen.
⋅ Reading a file
Text–format files can be read from a memory card.

NOTE
When using the program stored on a memory card to make
a subprogram call for RMT mode operation (DNC operation)
or the M198 command, use the special retainer for securing
a memory card to the CNC.
If an attempt is made to write parameters or NC programs to an existing
file on the memory card, the OWM parameter (bit 6 of parameter No.
0138) can be used to specify whether to display an overwriting
confirmation message. If OWM = 1, overwriting is done with no
confirmation message displayed.
When you press the [EXEC] soft key after the [PUNCH] soft key, the
confirmation message shown below appears on the lower left corner of the
screen, if the memory card already contains a file by the same name as
specified.
