S1+19 AT
Sampling
Period
The
AT
sampling
period
determines
the
interval
of
sampling
during
auto
tuning.
When
using
auto
tuning
with
operation
mode
(S1+3)
set
to
1
(AT+PID)
or
2
(AT),
set
a
required
value
of
1
through
10000
to
specify
an
AT
sampling
period
of
0.01
sec
through
100.00
sec
to
the
data
register
designated
by
S1+19.
When
S1+19
stores
0,
the
AT
sampling
period
is
set
to
0.01
sec.
When
S1+19
stores
a
value
larger
than
10000,
the
AT
sampling
period
is
set
to
100.00
sec.
Set
the
AT
sampling
period
to
a
long
value
to
make
sure
that
the
current
process
variable
is
smaller
than
or
equal
to
the
previous
process
variable
during
direct
control
action
(S2+0
is
on)
or
that
the
current
process
variable
is
larger
than
or
equal
to
the
previous
process
variable
during
reverse
control
action
(S2+0
is
off).
When
using
advanced
auto
turing
with
operation
mode
(S1+3)
set
to
3
(advanced
AT+PID)
or
4
(advanced
AT),
the
AT
sampling
period
is
determined
automatically
and
does
not
have
to
be
set
by
the
user.
S1+20 AT
Control
Period
The
AT
control
period
determines
the
duration
of
the
ON/OFF
cycle
of
the
control
output
(S2+6)
during
auto
tuning.
For
operation
of
the
control
output,
see
“Control
Period”
on
When
using
auto
tuning
with
operation
mode
(S1+3)
set
to
1
(AT+PID)
or
2
(AT),
set
a
required
value
of
1
through
500
to
specify
an
AT
control
period
of
0.1
sec
through
50.0
sec
to
the
data
register
designated
by
S1+20.
When
S1+20
stores
0,
the
AT
control
period
is
set
to
0.1
sec.
When
S1+20
stores
a
value
larger
than
500,
the
AT
control
period
is
set
to
50.0
sec.
When
using
advanced
auto
turing
with
operation
mode
(S1+3)
set
to
3
(advanced
AT+PID)
or
4
(advanced
AT),
the
AT
con
‐
trol
period
is
determined
automatically
and
does
not
have
to
be
set
by
the
user.
S1+21 AT
Set
Point
While
auto
tuning
is
executed,
the
AT
output
manipulated
variable
(S1+22)
is
outputted
to
the
output
manipulated
vari
‐
able
(S1+1)
until
the
process
variable
(S1+0)
reaches
the
AT
set
point
(S1+21).
When
the
process
variable
(S1+0)
reaches
the
AT
set
point
(S1+21),
auto
tuning
is
complete
and
the
output
manipulated
variable
(S1+1)
is
reduced
to
zero.
When
PID
action
is
selected
with
operation
mode
(S1+3)
set
to
1
(AT+PID)
or
3
(advanced
AT+PID),
the
PID
action
follows
imme
‐
diately.
When
the
operation
mode
(S1+3)
is
set
to
1
(AT+PID),
2
(AT),
or
4
(advanced
AT),
set
a
required
AT
set
point
to
the
data
register
designated
by
S1+21.
When
the
operation
mode
(S1+3)
is
set
to
3
(advanced
AT+PID),
the
AT
set
point
is
deter
‐
mined
automatically
and
does
not
have
to
be
set
by
the
user.
When
the
linear
conversion
is
disabled
(S1+4
set
to
0
or
2),
set
a
required
AT
set
point
of
0
through
4095
or
50000
depending
on
the
analog
I/O
module
type
to
the
data
register
designated
by
S1+21.
When
S1+21
stores
a
value
larger
than
4095
or
50000,
the
AT
set
point
is
set
to
4095
or
50000.
When
the
linear
conversion
is
enabled
(S1+4
set
to
1
or
3),
set
a
required
AT
set
point
of
0
through
65535
(word
data
type)
or
–32768
through
32767
(integer
data
type)
to
the
data
register
designated
by
S1+21.
The
AT
set
point
must
be
larger
than
or
equal
to
the
linear
conversion
minimum
value
(S1+6)
and
must
be
smaller
than
or
equal
to
the
linear
con
‐
version
maximum
value
(S1+5).
In
the
direct
control
action
(see
set
the
AT
set
point
(S1+21)
to
a
value
sufficiently
smaller
than
the
process
variable
(S4)
at
the
start
of
the
auto
tuning.
In
the
reverse
control
action,
set
the
AT
set
point
(S1+21)
to
a
value
suffi
‐
ciently
larger
than
the
process
variable
(S4)
at
the
start
of
the
auto
tuning,
otherwise
the
process
variable
(S1+0)
cannot
reach
the
AT
set
point
(S1+21)
and
AT
parameters
cannot
be
determined.
S1+22 AT
Output
Manipulated
Variable
The
AT
output
manipulated
variable
specifies
the
amount
of
the
output
manipulated
variable
(0
through
100)
during
auto
tuning.
When
using
auto
tuning,
set
a
required
AT
output
manipulated
variable
of
0
through
100
to
the
data
register
des
‐
ignated
by
S1+22.
When
S1+22
stores
a
value
larger
than
100,
the
AT
output
manipulated
variable
is
set
to
100.
While
auto
tuning
is
executed,
the
specified
value
of
the
AT
output
manipulated
variable
(S1+22)
is
outputted
to
the
out
‐
put
manipulated
variable
(S1+1),
and
the
control
output
(S2+6)
is
turned
on
and
off
according
to
the
AT
control
period
(S1+20)
and
the
AT
output
manipulated
variable
(S1+22).
To
keep
the
control
output
(S2+6)
on
during
auto
tuning,
set
100
to
S1+22.
When
using
advanced
auto
turing
with
operation
mode
(S1+3)
set
to
3
(advanced
AT+PID)
or
4
(advanced
AT),
the
AT
out
‐
put
manipulated
variable
is
determined
automatically
and
does
not
have
to
be
set
by
the
user.
