4.3
Limitation on the Number of Input/Output Points
With the FX5UC CPU modules, a total of 512 points including the number of input/output points of extension devices (max.
256 points) and the number of remote I/O points (max. 384 points) can be controlled.
*1 A bus conversion module is required when using the FX3U-16CCL-M.
*2 A bus conversion module is required when using the FX3U-128ASL-M.
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.
