3-1 Assignment of the input/output numbers
The assignment of the input/output numbers is decided depending on the I/O connector numbers
of the base unit and the types and arrangement of the input/output units installed there.
As an example, the decision of the input/sutput numbers will be shown for the following unit
composition.
Rase unit
Basic
R 1 8 B
Extended
K
6 8 H
Power supply unit
K 6 2 f '
CPU unit
K 1 C I'
U,
External failure manitor
Input unit (for data)
Output unit (for data)
Input unit (DC 24 V)
Input unit (AC 100 V)
Output unit (AC 100 V)
Output unit (AC 100 V)
Input/output composite unit
K N 6 I
K X 3 1
K Y 3 1
K X 3

K X l O
K Y l 1
K Y 2 2
K f 1 1 1

When the units are selected in this way, the unit arrangement becomes as shown in Fig. 3-2. for
therbase unit K18B and K68B.
(1)Unit arrangement
When the unit arrangement is entered into the "Unit arrangement table sheets Nos.l/2 and
2/2", it becomes as shown in Fig. 3-3-1, 3-3-2. When the I/O units are arranged sequentially
from 0 on the number of points of each I/O unit is specified and entered on the lower left of
the table, so that the number of required points according to the configuration is obtained. The
purpose of the input/output is entered in the application column and the upper 2 digits of the
I/O number are entered. Use sequential numbering with left justification in units of 16 points,
Le., 00, 01, 02,
...
OF.
Note: The input/output numbers are hexadecimal numbers. (Indication method:
0 0 El#)
0, 1, 2, 3, 4, 5, 6,
7, 8,
9, A, B, C, D, E, F
...
The figure increases by one digit when F is reached.
(2)Definition of the input/output numbers (drawing up of the input/output list)
When the I/O adress "OA" is decided as shown in Fig. 3-1 (decision in hexadecimal units as 1,
2,
...,
to"OA", the numbers for each input/output are necessarily defined on a 1 point cor-
respondence.
