Editing the detailed remote station information
After assigning the I/O numbers in the CONFIG mode, the I/O number assignment in each
station number can be edited.
With this function, the number of I/O points can be changed, and the I/O numbers can be
assigned to unconnected station numbers for future use. If remote stations are added in the
future, it is not necessary to change the I/O numbers in other remote stations and extension
blocks/units connected to the PLC.
If a remote station is not connected to an edited station number, errors such as wire breakage
error will occur.
If a remote station is connected to an edited station number the remote station will operate with
the existing setting.
