1 OVERVIEW
(2) Assignment of I/O No. to the Motion CPU control module
Mitsubishi recommends that I/O No. assignment be set as common consecutive
No. throughout all CPUs.
However, the I/O No. of the Motion CPUs control input modules, output modules
and input/output composite modules may also be set independently of the I/O
No. of the PLC CPU control modules.
(The I/O No. of the Motion CPU control modules are indicated with a PX/PY.)
The I/O No. of the Motion CPU control modules are invalid during I/O Assignment
Settings of the PLC CPU.

(3) Setting of the Motion CPU control modules by the PLC CPU
Follow the table below when the Motion CPU control modules are set in I/O
Assignment Settings of the PLC CPU. (The PLC CPU handles the Q172LX and
Q173PX as intelligent function modules having 32 occupied points.) Type and
number of points may be left unset.

• For the control CPU, set
the CPU that
corresponds to the
Motion CPU (required).
• Type and number of
points may be left unset.
POINT
(1) Set the I/O device of the Motion CPU within the range from PX/PY000 to
PX/PYFFF. Set the number of real I/O points within 256 points. (I/O No. may
not be consecutive.)
(2) As for the Motion CPU, the Q172LX and Q173PX are not included in the
number of real I/O points.
