+
PID
action
Auto
tuning
is
first
executed
according
to
the
AT
parameters
which
are
designated
automatically,
such
as
AT
sampling
period
(S1+19),
AT
control
period
(S1+20),
AT
set
point
(S1+21),
and
AT
output
manipulated
variable
(S1+22).
As
a
result
of
auto
tuning,
PID
parameters
are
determined
such
as
proportional
term
(S1+7),
integral
time
(S1+8),
derivative
time
(S1+9),
sampling
period
(S1+12),
control
period
(S1+13),
and
control
direction
(S2+0),
then
PID
action
is
executed
according
to
the
derived
PID
parameters.

Advanced
AT
(auto
tuning)
Auto
tuning
is
executed
according
to
automatically
designated
AT
parameters,
except
for
AT
set
point
(S1+21),
to
determine
PID
parameters
such
as
proportional
term
(S1+7),
integral
time
(S1+8),
derivative
time
(S1+9),
sampling
period
(S1+12),
control
period
(S1+13),
and
control
direction
(S2+0);
PID
action
is
not
executed.
Device
Designations
by
Operation
Mode
(S1+3)
The
following
table
summarizes
devices
which
have
to
be
designated
for
each
operation
mode.
When
auto
tuning
is
used,
several
devices
are
automatically
determined
and
do
not
have
to
be
designated.
*
While
the
PID
action
is
in
progress
(operating
status
S1+1
is
5X
or
6X),
these
values
can
be
changed
for
fine
tuning.
Be
careful
improper
changes
may
result
in
undesired
operation.
S1+4 Control
Mode
(Linear
Conversion
and
Proportional
Term)
The
control
mode
designates
whether
to
disable
or
enable
the
linear
conversion
and
whether
the
proportional
term
uses
the
proportional
gain
or
proportional
band.
Note:
While
the
PID
action
is
in
progress
(operating
status
S1+1
is
5X
or
6X),
do
not
change
the
control
mode
(S1+4),
otherwise
the
PID
action
may
result
in
an
error
and
stop
operation.
Disable
linear
conversion
Linear
conversion
is
not
executed.
When
the
linear
conversion
is
disabled
(S1+4
set
to
0
or
2),
the
analog
input
data
(0
through
4095
or
50000,
depending
on
the
analog
I/O
module
type)
from
the
analog
I/O
module
is
stored
to
the
process
variable
(S4),
and
the
same
value
is
stored
to
the
process
variable
(S1+0)
without
conversion.
Enable
linear
conversion
The
linear
conversion
function
is
useful
for
scaling
the
process
variable
to
the
actual
measured
value
in
engineering
units.
When
the
linear
conversion
is
enabled
(S1+4
set
to
1
or
3),
the
analog
input
data
(0
through
4095
or
50000,
depending
on
the
ana
‐
log
I/O
module
type)
from
the
analog
I/O
module
is
linear
‐
converted,
and
the
result
is
stored
to
the
process
variable
(S1+0).
When
using
the
linear
conversion,
set
proper
values
to
the
linear
conversion
maximum
value
(S1+5)
and
linear
conversion
minimum
value
(S1+6)
to
specify
the
linear
conversion
output
range.
When
using
the
linear
conversion
function
in
a
temperature
control
applica
‐
tion,
temperature
values
can
be
used
to
designate
the
set
point
(S3),
high
alarm
value
(S1+14),
low
alarm
value
(S1+15),
and
AT
set
point
(S1+21),
and
also
to
read
the
process
variable
(S1+0).
