4.7 Assign I/O address
To read / write data I/O and special function modules, the CPU assigns I/O address (P
area) to each modules according to the module type. I/O address starts from P00 (word),
and it is assigned from left to right. The following figure shows an example of I/O address
allocation.

Main base (8 slots)
Remark
1. Special function modules occupy various I/O addresses according to the type of module.
Please see the user’s manual of each special function module for details
2. Special function modules can be mounted on any slots of main / expansion base. There is
also no limit on the number of special function modules mountable on a base.
3. In 2.0 or lower K300S/1000S CPU OS version , network module can be mounted on the
main base only.
