Number of I/O points (including the number of occupied I/O points)
The number of input/output points is the sum of the following numbers of the points.
• Number of input/output points on CPU module and I/O module
• Number of occupied input/output points of intelligent function modules, safety main modules, and bus conversion modules
■
Number of I/O points on CPU module and I/O modules
Count the total number of input/output points of the CPU module and I/O modules.
For the number of I/O points, count the total number of input points (X0 and more) and output points (Y0 and more) of the
CPU module and I/O modules.
For details on the number of I/O points by model, refer to the following.
• Example of number of I/O points
■
Number of occupied I/O points
Count the number of occupied input/output points of intelligent function modules, safety main modules, and bus conversion
modules.
The number of occupied I/O points per module is 8.
Extension power supply modules, connector conversion modules, expansion boards, and expansion adapters have no
occupied I/O points.

I/O points Description
CPU module FX5UJ-24MR/ES 10 points (16
points) 14 points (16
points) 24 points (32
points) The number in brackets "()" is the number of
occupied points. When calculating the total number
of I/O points, the values in the brackets "( )" are
used. The number of I/O points is therefore 32.
Number of input points (16) + Number of output
points (16) = Number of I/O points (32)
FX5U-32MT/ES 16 points 16 points 32 points The number of I/O points is 32.
Number of input points (16) + Number of output
points (16) = Number of I/O points (32)


No occupied points
Simple motion module FX5-40SSC-S 8 points Eight points are occupied because this module is an
intelligent function module.
Bus conversion module FX5-CNV-BUS 8 points Eight points are occupied because this module is a bus
conversion module.
Analog input FX3U-4AD 8 points Eight points are occupied because this module is an
intelligent function module.
