2.3 Basic System
2.3.1 Configuration method of Basic System
The features of Basic system consisted by connecting the main base and expanded base by a cable are
as follows. The number of steges of expanded base is limited according to the CPU type and the
allocation method of I/O No. is available to select the fixed type and variable type according to the
setting of basic parameter.

Allocation of
I/O No.
(fixed type)
• Each slot of base is allocated by 60 points regardless module installation and type.
• For one base, I/O no. of 16 slots is allocated. That is, the start no. of No.1 base becomes
P00640. (Refer to 2.3.2)
• The example of I/O no. of 12 Slot base is as below :

Allocation of
I/O no.
(variable type)
• The point is allocated according to the assignment of installation module per slot.
- If assigned installation module by I/O parameter, the assigned point is allocated.
- The slot not assigned by I/O parameter shall be allocated automatically according to actual
installation slot
(Note: 8 point module shall be allocated by 16 point.)
- The empty slot not assigned by I/O parameter shall be processed by 16 point.
• Available to assign the point only by I/O parameter without module assignment.
• The slot installed by special module or communication module is allocated by 16 point.
• The example of I/O no. of 12 Slot base is as below :
0 12345678910 11

Notes
1) The allocation method of I/O no. shall be set in basic parameter.
2) For Main base, the base no. is fixed as “0” and the expanded base has a switch to set the base no.
3) In case of setting module type by I/O parameter, it starts the operation when the type of actually installed
module is matched.
