- 170 -
DNC operation by a subprogram call (M198) in the storage mode
Procedure
1 Place the CNC in MEM mode.
2 Display the Hard Disk File Directory screen and move to the
directory holding an NC program to be called by a subprogram.
3 Press soft key [(OPRT)].
4 Press soft key [M198 D].
5 Press soft key [EXEC]. The name of the current work directory is
displayed to the right of "M198 DIRECTORY" on the screen.
6 An automatic operation is performed based on the NC program
containing the M198 command.
NOTE
1 If a subprogram is called with M98 from a DNC
operation subprogram called by an M198
subprogram call, and the M198 command is specified
from within the called subprogram, the second M198
command is treated as an M code for a
miscellaneous function command. If the M198
command is specified in a DNC operation
subprogram, PS alarm 210 is issued.
2 DNC operation by a subprogram call (M198) cannot
be executed simultaneously with NC program input,
NC program output, or DNC operation.
3 The file name of the subprogram to be called by DNC
operation by a subprogram call (M198) must be
Oxxxx.
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.
