Chapter 2 Basic Unit Specification
2. Digital input and output
2-7
With respect to expansion for 20 point basic unit, the input number for the first digital
(analogue) expansion unit should be start from X20 (D8436) and so on. WhileWhile the
output should be start from Y10 (D8381) and so on.
With respect to expansion for 30 point basic unit, the input number for the first digital
(analogue) expansion unit should be start from X20 (D8436) and so on. WhileWhile the
output should be start from Y20 (D8381) and so on.
With respect to expansion for 40 point basic unit, the input number for the first digital
(analogue) expansion unit should be start from X30 (D8436) and so on. WhileWhile the
output should be start from Y20 (D8381) and so on.
With respect to expansion for 60 point basic unit, the input number for the first digital
(analogue) expansion unit should be start from X50 (D8436) and so on. WhileWhile the
output should be start from Y30 (D8381) and so on.
For instance: If the user plans the following system, the number arrangement for I/O is suggested
in the table below:

Note:
a. When the basic unit expanded with both the expansion unit TP3-□□□ and
TP02-□□□, TP02-□□□ must be routed after TP3-□□□.
b. The basic unit TP03-20 xxx or TP03-30 xxx can expand maximum 32 points and 3
analogue units.
c. The basic unit TP03-40 xxx or TP03-60 xxx can expand maximum 64 points and 3
analogue units. An external power supply is needed if expansion units are more
than that. (as for the following example, the total I/O reaches 188 points)
