4.7.2 Concept of I/O assignment using GX Developer
In I/O assignment, the "Type (module type)", "Points (I/O points)" and "Start XY" (starting I/
O number) can be set for each slot of the base units.
For example, to change the number of occupied I/O points of the designated slot, only the
number of occupied I/O points can be designated.
The items other than designated are set to the status where the base unit is installed.

The I/O assignment is conducted at the "I/O assignment" tab screen in the "(PLC)
Parameter" dialog box.
