3 COMMON PARAMETERS
(2) I/O number assignment of Motion CPU control module
Mitsubishi recommends that I/O No. assignment be set as common consecutive
No. throughout all CPUs.
However, the I/O number of the input modules, output modules and input/output
composite modules controlled with the Motion CPU can also be set regardless as
the I/O number of PLC CPU.
(I/O number of the Motion CPU control modules is indicated as PX/PY.)
I/O number of the Motion CPU control modules cannot be assigned by I/O
assignment settings of PLC CPU.

(3) Setting of the Motion CPU control modules by the PLC CPU
Follow the table below when Motion CPU control modules are set in I/O
Assignment Settings of the PLC CPU. (The PLC CPU handles the Q172DLX,
Q172DEX and Q173DPX 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 Q172DLX, Q172DEX, Q173DPX and QI60 are not
included in the number of real I/O points.
