DNC operation by a subprogram call (M198) in the FTP 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 4.9.2, "Reconnecting the Host," to display the Host
File Directory screen.
3 Press soft key [(OPRT)].
4 Press soft key [M198 H].
5 Press soft key [EXEC]. The host number of the currently
connected host is displayed to the right of "M198 CONNECT
HOST" on the screen.
6 An automatic operation is performed based on the NC program
containing the M198 command.
NOTE
1 DNC operation by a subprogram call (M198) cannot
be executed simultaneously 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) must be
Oxxxx.
3 Assume that there is a subprogram called by DNC
operation by a subprogram call (M198) and that a
subprogram call is further executed in this
subprogram. If the subprogram to be called exists on
the tape memory, the subprogram can be executed.
If, however, the subprogram exists on the hard disk, it
cannot be executed as a subprogram.
4 When viewed from the CNC, the data server function
is handled in the same way as for other input/output
equipment. Therefore, the subprogram call
restrictions are the same as those for other
input/output equipment.
5 Multipath control can be performed on DNC
operations by a subprogram call (M198) on multiple
paths at a time; however, the programs must be in
the same work directory.
