Mode: Automatic; Method: G language (D code output)
It is possible to set a D code in the G-language program related to positioning
as an interrupt to the CPU Unit. The specified D code is output after position-
ing is completed, and the CPU Unit executes an interrupt task taking the D
code (0 to 255) as the task number.
When the stopover function is used, this D code can be output during opera-
tion without stopping the operation. For details on the stopover function, refer
to 6-10 Stopover Function.
Note This interrupt function can be used only when the MC Unit is mounted to the
CPU Backplane. It cannot be used if the MC Unit is mounted to an Expansion
I/O Rack.
When an interrupt task is used in the CPU Unit, a setting must be made in the
PLC Setup. For details, refer to the manual for the CPU Unit.
Overlapping section
M code/D code not output if
a position in this range is
specified in the previous
operation.
M code/D code output at the
beginning of the overlapping
section if a position in the
overlapping area is specified
in the next operation.
