Timer/counter
Input relays
The
CPU
has
16
input
relay
points
(one
input
channel).
The
number
of
input
points
can
be
increased
to
a
maximum
of
80
by
the
addition
of
expansion
I/O
units.
Because
one
channel
equals
16
points,
this
means
that
a
maximum
of
five
channels
(from
channel
00
to
04)
are
available.
The
data from
the
SYSBUS
are
received
by
the
input
channel
relays
assigned
to
the
I/O
link
unit.
Output relays
As
with
the
input
relays,
the
CPU
has
one
output
channel
consisting
of
16
relay
points.
However,
of
these
16
points,
numbers
12
to
15
are
internal
auxiliary
relays
used
to
carry
out
CPU
internal
processes.
For
this
reason,
the
number
of
output
relays
the
CPU
actually
possesses
is
12.
When
expansion
I/O
units
are
connected
to
the
CPU,
a
maximum
of
60
output
relays
are
available
for
a
total
of
five
channels,
05
to
09.
The
statuses
of
all
the
output
channel
relays
assigned
to
the
I/O
link
unit
are
transferred
to
the
SYSBUS
when
an
1/0
link
unit
is employed.
Internal auxiliary relays
The
CPU
has
136
internal
auxiliary
relays
(No.
1000
to
1807)
that
constitute channels 10 to 18.
Holding relays (retentive relays)
The
CPU
has
160
holding
relays
(No.
HROOO
to
915)
that
constitute
holding
relay
channels
0
to
9.
The
holding
relay
retains
data
during
power
failure.
Timers/counters
The
CPU
has
48
points
of
timers/counters,
TIM/CNTO0
to
47,
that
can
be
used
for
either
timers
or
counters.
Timers
and
counters
cannot
be
assigned
the
same
number.
