Setting method
Configure the remote I/O station points setting in "Network Configuration Settings" under "Basic Settings". ( Page 60
Network Configuration Settings)
When setting eight-point remote I/O stations, set an even number of stations consecutively. When setting an
odd number of eight-point remote I/O stations, select "8 Points + Empty 8 Points" from "Remote Station
Points" for the last of consecutive remote I/O stations.
The following figure shows an example of when three output modules with eight points are connected.

When the number of remote I/O stations is odd, eight points cannot be set in the remote station points.

This parameter cannot be set using dedicated instructions. Therefore, read or write data from/to the device in
a CPU module according to the number of I/O points of each station using a program. Consequently, the
areas in refresh devices can be saved.
• Reading/writing data using a module access device (Un\G)
• Reading/writing data using the FROM/TO instructions
Precautions
Set the number of points greater than the I/O points of a remote I/O station connected. If the smaller number of points is set in
a station, data cannot be normally input to or output from stations after that.
