Confirming the I/O Allocation and Slot Number

The I/O numbers and slot numbers are always necessary when creating a program.
These vary depending on the position at which the serial data unit is installed in the
backplane. Always check to see if the numbers match the design.
3.3.3.1

Confirming the I/O Number Allocations

The occupied I/O areas for all of the units mounted between the CPU unit and the FP2
serial data unit should be confirmed. These are allocated as I/O areas for the serial data
unit, starting from the serial number.
Example:
The following is an example of FP2 serial data unit being
mounted in succession following three 16−point I/O units.

Notes
•
If there are any empty slots between the CPU unit and the
serial data unit, check to see whether an I/O area has been
allocated to the empty slot.
•
If I/O mount allocation and automatic allocation are being
carried out, 16 points for each type of allocation will
automatically be assigned to empty slots.
•
If the CPU unit being used is a 2−module type, also check any
I/O areas occupying the units incorporated in the CPU unit.
•
For information on how I/O allocations are made, refer to the
FP2/FP2SH User's Manual.
