1 OVERVIEW
(3) Setting of the Motion CPU control modules by the PLC CPU
(a) Type/number of points
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 Q172LX,
Q172EX 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, Q172EX, Q173PX and QI60 are not
included in the number of real I/O points.
(b) If the installed Motion CPU control module is different from the I/O
assignment type of PLC CPU, the operation is abnormal.
