(1) Group No.
Up to two I/O units can be connected using the additional I/O
interface module AIF01B, based on I/O interface AIF01A. Up to two
I/O units extended from AIF01A are called a group. When only one
interface module is not enough to accommodate the required I/O
modules, or when multiple I/O units are separately located remote
from the machine, connect the first AIF01A and the second AIF01A
with the cable. Up to 16 groups of I/O units can be connected.
(2) Base No.
In one group, there are 2 max. I/O base units. The I/O unit with the
I/O interface module IF01A is assigned to base No. 0 and another is
assigned to base No.1.
(3) Slot No.
A maximum of 5 or 10 I/O modules can be mounted on the I/O base
unit ABU05A, ABU10A, respectively. The module mounting
position on the I/O base unit is expressed with slot Nos. In each base
unit, the mounting position of the I/O interface module is assigned
to slot No. 0, and slot No. 1, 2, 3 ... are assigned in order from the left.
In the case of I/O base unit (BU10B) for 10 slots, slot No. 1, 2 follow
slot No. 8. The last slot No. 1, 2 are assigned for the next base
address. Each module can be mounted on an arbitrary slot. It is
possible to mount modules by skipping some slots.
