4.3 Limitation on the Number of Input/Output Points
Total number of I/O points and remote I/O points
With the FX5U CPU module, a total of 512 points or less including the number of input/output points of extension devices and
number of remote I/O points can be controlled.
The total number of I/O points and remote I/O points must not exceed 512 points.
Calculation of number of input/output points
The number of input/output points is the total of the number of input/output points of the CPU module and I/O module, and the
number of occupied input/output points of intelligent function modules.
The total number of input/output points must not exceed 256 points.
Total number of input/output points of the CPU module and I/O modules
Count the total number of input/output points of the CPU module and I/O modules.
To obtain the total number of input/output points, count the 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 input/output points by model, refer to the following.
Number of occupied input/output points of intelligent function modules
Count the number of occupied input/output points of intelligent function modules.
The number of occupied input/output points per module is 8.
For details on the number of occupied input/output points by model, refer to
Page 43 Intelligent Function Module.
