S2+5 Low
Alarm
Output
When
the
process
variable
(S1+0)
is
lower
than
or
equal
to
the
low
alarm
value
(S1+15),
the
low
alarm
output
control
relay
(S2+5)
goes
on.
When
S1+0
is
higher
than
S1+15,
S2+5
is
off.
S2+6 Control
Output
During
auto
tuning
in
auto
mode
with
the
auto/manual
mode
control
relay
(S2+1)
set
to
off,
the
control
output
(S2+6)
is
turned
on
and
off
according
to
the
AT
control
period
(S1+20)
and
AT
output
manipulated
variable
(S1+22).
During
PID
action
in
auto
mode
with
the
auto/manual
mode
control
relay
(S2+1)
set
to
off,
the
control
output
(S2+6)
is
turned
on
and
off
according
to
the
control
period
(S1+13)
and
the
output
manipulated
variable
(S1+1)
calculated
by
the
PID
action.
While
advanced
auto
tuning
is
in
progress,
the
control
output
(S2+6)
remains
on.
In
manual
mode
with
the
auto/manual
mode
control
relay
(S2+1)
set
to
on,
the
control
output
(S2+6)
is
turned
on
and
off
according
to
the
control
period
(S1+13)
and
the
manual

output
manipulated
variable
(S1+18).
S2+7 AT
Complete
Output
The
AT
complete
output
control
relay
(S2+7)
goes
on
when
auto
tuning
is
complete
or
failed,
and
remains
on
until
reset.
Operating
status
codes
are
stored
to
the
operating
status
control
register
(S1+2).
See
Source
Device
S3
(Set
Point)
The
PID
action
is
executed
to
adjust
the
process
variable
(S1+0)
to
the
set
point
(S3).
When
the
linear
conversion
is
disabled
(S1+4
set
to
0
or
2),
set
a
required
set
point
value
of
0
through
4095
or
50000,
depending
on
the
analog
I/O
module
type,
to
the
device
designated
by
S3.
Valid
devices
are
data
register
and
constant.
When
the
linear
conversion
is
enabled
(S1+4
set
to
1
or
3),
designate
a
data
register
as
device
S3
and
set
a
required
set
point
value
of
0
through
65535
(word
data
type)
or
–32768
through
32767
(integer
data
type)
to
the
data
register
desig
‐
nated
by
S3.
The
set
point
value
(S3)
must
be
larger
than
or
equal
to
the
linear
conversion
minimum
value
(S1+6)
and
smaller
than
or
equal
to
the
linear
conversion
maximum
value
(S1+5).
When
an
invalid
value
is
designated
as
a
set
point,
the
PID
action
is
stopped
and
an
error
code
is
stored
to
the
data
regis
‐
ter
designated
by
S1+2.
See
“Operating
Status”
on
Source
Device
S4
(Process
Variable
before
Conversion)
The
PID
instruction
is
designed
to
use
analog
input
data
from
an
analog
I/O
module
as
process
variable.
The
analog
I/O
module
converts
the
input
signal
to
a
digital
value
of
0
through
4095
or
50000,
and
stores
the
digital
value
to
a
data
reg
‐
ister
depending
on
the
mounting
position
of
the
analog
I/O
module
and
the
analog
input
channel
connected
to
the
ana
‐
log
input
source.
Designate
a
data
register
as
source
device
S4
to
store
the
process
variable.
For
the
data
register
number
to
designate
as
source
device
S4,
see
page
(
Basic
Vol.)
.
Specify
the
data
register
number
shown
under
Data
in
the
Configure
Parameters
dialog
box
as
source
device
S4
(process
variable)
of
the
PID
instruction.
The
analog
input
data
in
the
selected
data
register
is
used
as
the
process
variable
of
the
PID
instruction.
Destination
Device
D1
(Manipulated
Variable)
The
data
register
designated
by
destination
device
D1
stores
the
manipulated
variable
of
–32768
through
32767
calcu
‐
lated
by
the
PID
action.
When
the
calculation
result
is
less
than
–32768,
D1
stores
–32768.
When
the
calculation
result
is
greater
than
32767,
D1
stores
32767.
While
the
calculation
result
is
less
than
–32768
or
greater
than
32767,
the
PID
action
still
continues.
When
the
output
manipulated
variable
limit
is
disabled
(S2+2
set
to
off)
while
the
PID
action
is
in
progress,
the
data
reg
‐
ister
designated
by
S1+1
holds
0
through
100
of
the
manipulated
variable
(D1),
omitting
values
less
than
0
and
greater
than
100.
The
percent
value
in
S1+1
determines
the
ON
duration
of
the
control
output
(S2+6)
in
proportion
to
the
control
period
(S1+13).
When
the
output
manipulated
variable
limit
is
enabled
(S2+2
set
to
on),
the
manipulated
variable
(D1)
is
stored
to
the
output
manipulated
variable
(S1+1)
according
to
the
output
manipulated
variable
upper
limit
(S1+16)
and
the
output
manipulated
variable
lower
limit
(S1+17)
as
summarized
in
the
table
below.
