Calculation of number of input/output points

To obtain the total number of input/output points, count the input/output points of input/output powered
extension units/blocks and the input/output occupied points of special function blocks.
The number of remote I/O points on CC-Link network must be excluded.
1
Total the number of input/output points on the main unit and the number of
those on the input/output powered extension units/blocks.
To obtain the total number of input/output points, count the input points (X000 and more) and output
points (Y000 and more) of the main unit and input/output powered extension units/blocks.
The number of input/output points of each type of device is shown on the list below.
2
Count the input/output points of the remote I/O stations connected on FX
64CL-M network.
Add the number of remote I/O points to the number of input/output points from the main unit and
input/output powered extension units/blocks calculated in the above step.
3
Count the number of input/output occupied points of special function blocks.
The number of occupied input/output points per unit is 8.
The number of occupied input/output points of each type of device can be obtained by the following
formula or from the list shown below.
