The
input
channel
of
the
CPU
is
fixed
at
channel
00
while
the
output
channel
is
fixed
at
channel
05.
When
an
expansion
I/O
unit,
I/O
link
unit,
or
both
are
connected
to
the
CPU,
the
I/O
channel
of
the
connected
units
are
automatically
assigned
and
registered
in
the
CPU.
For
example,
when
a
28-point
expansion
I/O
unit
is
connected,
input
channel
01
is
automatically
assigned
to
the
expansion
I/O
unit
and
registered
in
the
CPU.
As
the
output
channel
number
of
the
expansion
unit,
06
is
automatically
assigned
and
registered.
The
input/output
signals
(devices)
are
connected
to
the
input/output
terminals
on
the
CPU.
Because
the
CPU
uses
the
numbers
assigned
to
the
input/output
terminals
when
executing
the
program,
assignment
and
management
of
the
input/output
terminal
numbers
are
required
and
must
be
correctly
performed.
The
numbers
assigned
to
each
relay
are
listed
in
the
following
tables.
Use
these
to
keep
a
record
of
which
relays
have
been
used.
