Total number of I/O points and remote I/O points

With the FX5UC 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 the number of input/output points

The number of input/output points is a total of the number of input/output points of the CPU module, 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.
