DNC operation by a subprogram call (M198) in buffer mode
Procedure
1 Place the CNC in MEM mode.
2 Select the host number for the host holding an NC program to be
called by a subprogram according to the procedure described in
Subsection 6.9.2, "Reconnecting the Host," to display the Host
Directory screen.
3 Press the operation menu key at the right end of the soft key menu.
4 Press soft key [M198 HOST SET].
5 Press soft key [EXEC]. The current connection host number is
displayed in M198 HOST on the screen.
6 The NC program containing the M198 directive is automatically
executed.
NOTE
1 DNC operation by a subprogram call (M198) cannot
be executed concurrently with NC program input, NC
program output, or DNC operation.
2 The file name of the subprogram to be called by DNC
operation by a subprogram call (M198) becomes
Oxxxx if the O number is between 1 and 9999. If the
O number is between 10000 and 9999999, the file
name becomes Oxxxxxxx. If the O number is
between 10000000 and 99999999, the file name
becomes xxxxxxxx.
3 Assume that a subprogram call is further performed
in the subprogram called by the DNC operation by a
subprogram call (M198). If the subprogram to be
called exists in tape memory, it can be executed as a
subprogram. If, however, this subprogram exists in
the Fast data server built-in ATA card, it cannot be
executed as the subprogram.
4 When viewed from the CNC, the data server
functions are handled in the same way as for other
input/output equipment. So, the subprogram call
restrictions are equivalent to those for other
input/output equipment.
