8.4.4 DI/DO Connector Pin Assignment
This section describes the DI/DO connector pin allocation of the basic
module and expansion modules A and B.
NOTE
1 The DI and DO addresses for the basic and
extension modules run contiguously. These basic
and extension module DI and DO addresses are
allocated to the I/O Link as a group. For example,
when the DI and DO top addresses are X0004 and
Y0000 (m = 4 and n = 0), respectively, then the
addresses are allocated as shown in the following
table.
2 Pins 18 and 50 (+24V) of connector CB150 are
used to apply 24 V externally to a module. Be
sure to connect these pins because the +24 V
applied to the module is used internally.
DI DO
Basic module X4 to X6 Y0 to Y1
Extension module 1 X7 to X9 Y2 to Y3
Extension module 2 X10 to X12 Y4 to Y5
Extension module 3 X13 to X15 Y6 to Y7
