1.8 Number of Input/Output Points and Maximum Number of Input/Output
Points
The number of input/output points and maximum number of input/output points varies depending on the PLC
version and network type.
*1. For the number of input/output points and maximum number of input/output Points, refer to Section
1.7.
1.8.1 Calculation of number of input/output points
To obtain the total number of input/output points, count the input/output points of input/output extension
blocks, the remote I/O points of the FX
3UC-32MT-LT buit-in master and the input/output occupied points of
special function units/blocks.
1. Total the number of input/output points on the main unit and the number of those on the
input/output extension blocks.
To obtain the total number of input/output points, count the input points (X000 and higher) and output points
(Y000 and higher) of the main unit and input/output extension blocks.
2. Count the input/output points of the remote I/O stations connected to the FX3UC-32MT-LT
built-in master, FX
2N-64CL-M or FX2N-16LNK-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.
→ For the method of calculating the number of remote I/O points (CC-Link/LT built-in master),
refer to Chapter 9.
→ For the method of calculating the number of remote I/O points (FX
2N-64CL-M),
refer to the FX
2N-64CL-M manual.
→ For the method of calculating the number of remote I/O points (FX
2N-16LNK-M),
refer to the FX2N-16LNK-M manual.
3. Count the number of input/output occupied points of special function units/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.
→ For a list of occupied input/output points, refer to Section 1.11.
Observe the following instructions when using the following products.
