Editing the detailed remote station information

After assigning the I/O Nos. in the CONFIG mode, the I/O No. assignment in each station No.
can be edited.
With this function, the number of I/O points can be changed, and the I/O Nos. can be assigned
to unconnected station Nos. for future use. If remote stations are added in the future, it is not
necessary to change the I/O Nos. in other remote stations and extension blocks/units
connected to the PLC.
If a remote station is not connected to an edited station No., errors such as wire breakage error
will occur.
If a remote station is connected to an edited station No. the remote station will operate with the
existing setting.
