Note:
The
value
stored
in
the
data
register
designated
by
S1+3
(operation
mode)
is
checked
only
when
the
start
input
for
the
PID
instruction
is
turned
on.
Values
in
all
other
control
registers
are
refreshed
in
every
scan.
S1+0 Process
Variable
(after
conversion)
When
the
linear
conversion
is
enabled
(S1+4
set
to
1
or
3),
the
data
register
designated
by
S1+0
stores
the
linear
conver
‐
sion
result
of
the
process
variable
(S4).
The
process
variable
(S1+0)
takes
a
value
between
the
linear
conversion
minimum
value
(S1+6)
and
the
linear
conversion
maximum
value
(S1+5).
When
the
linear
conversion
is
disabled
(S1+4
is
set
to
0
or
2),
the
data
register
designated
by
S1+0
stores
the
same
value
as
the
process
variable
(S4).
S1+1 Output
Manipulated
Variable
While
the
PID
action
is
in
progress,
the
data
register
designated
by
S1+1
holds
0
through
100
read
from
the
manipulated
variable,
–32768
through
32767,
stored
in
the
data
register
designated
by
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).
While
manual
mode
is
enabled
with
the
auto/manual
mode
control
relay
(S2+1)
set
to
on,
S1+1
stores
0
through
100
read
from
the
manual
mode
output
manipulated
variable
(S1+18).
While
auto
tuning
(AT)
is
in
progress,
S1+1
stores
0
through
100
read
from
the
AT
output
manipulated
variable
(S1+22).
S1+2 Operating
Status
The
data
register
designated
by
S1+2
stores
the
operating
or
error
status
of
the
PID
instruction.
Status
codes
1X
through
6X
contain
the
time
elapsed
after
starting
auto
tuning
or
PID
action.
X
changes
from
0
through
9
in
10
‐
minute
increments
to
represent
0
through
90
minutes.
The
time
code
remains
9
after
90
minutes
has
elapsed.
When
the
operation
mode
(S1+3)
is
set
to
1
(AT+PID),
the
time
code
is
reset
to
0
at
the
transition
from
AT
to
PID.
Status
codes
100
and
above
indicate
an
error,
stopping
the
auto
tuning
or
PID
action.
When
these
errors
occur,
a
user
program
execution
error
will
result,
turning
on
the
ERR
LED
and
special
internal
relay
M8004
(user
program
execution
error).
To
continue
operation,
enter
correct
parameters
and
turn
on
the
start
input
for
the
PID
instruction.
