2 SYSTEM CONFIGURATION
(4) I/O allocations
It is possible to allocate unique I/O No.s for each Motion CPU area independently
of the PLC CPU area's I/O No.s.
ON/OFF data input to the Motion CPU area is handled via input devices PX
while ON/OFF data output from the Motion CPU area is handled via output
devices PY .
It is not mandatory to match the I/O device PX/PY No.s used in the Motion
program with the PLC I/O No.s; but it is recommended to make them match as
much as possible.
The following figure shows an example of I/O allocation.

X0 to X1F
(Note-1) : When the number of modules to be installed is 32 points.
(Note-2) : When the PX/PY No. does not match the PLC I/O No.
Refer to the Q173DCPU/Q172DCPU Motion Controller Programming Manual
(COMMON) about the I/O allocation setting method of the Motion CPU area, and refer
to APPENDIX 1.6 and the "QCPU User's Manual (Function Explanation, Program
Fundamentals)" about the I/O allocation setting method of the PLC CPU area.
POINT
I/O device of the Motion CPU area can be set in the range PX/PY000 to PX/PYFFF.
The real I/O points must be 256 points or less. (As for the I/O No., it is possible not
to continue.)
