I/O numbers
• The I/O numbers of one slot (one module) are assigned in ascending order in 16-point unit (0 to F
H
).
As a standard, 16-point modules should be attached to all slots.
For example, the following figure shows the I/O numbers of when a 32-point module is attached to the fifth slot.

• The I/O numbers are also assigned to a vacant slot (a slot with no I/O module installed).
For example, if the third slot is vacant, the I/O numbers are assigned as shown below. (in the initial setting)
The number of assigned points can be changed by the setting.

• For the multiple CPU configuration (two to four CPUs), the I/O numbers are assigned from a slot next to a slot where
a CPU is attached.
