System area of remote I/O
As to the number of remote I/O points (RX00 to RX7F/RY00 to RY7F) in the FX

number of points vary depending on the selected number of stations (1 to 4).
The upper 16 points of the final station are occupied by the CC-Link system as the system area, so cannot be
used as the user area. (
