4.4.6 Reducing the reserved points of the remote I/O stations (Remote I/O station points
setting)
The points of each remote I/O station can be set to 8, 16 or 32 points.
Therefore, only the points used for I/O need to be allocated for the remote devices in
the CC-Link system and unused points can be reduced. It is effective for saving device
points.
The remote I/O station points setting can be used in the remote net ver.2 mode only.
