Setting
range
Description
switched from ON to OFF,
the MV involved in the
internal algorithm is
involved in the automatic
algorithm.
If the setting value
exceeds the range, it will
be counts as 0.
PID_MAN
BOOL
PID A/M mode
True: Manual
The MV is output
according to the
MOUT, but it is still
within the range
between the MV_MIN
and the MV_MAX.
When PID_MODE is
set to 1, the setting is
ineffective.
False: Automatic
The MV is output
according to the PID
algorithm, and the
output value is within
the range between
MV_MIN and
MV_MAX.
MOUT_AUTO
BOOL
MOUT automatic change
mode
True: Automatic
The MOUT varies with
the MV.
False: Normal
The MOUT deos not
vary with the MV.

Sampling time (T
S
)
1~2,000
(unit:
10ms)
When the
instruction is
scanned, the
PID algorithm
is implmented
according to
the sampling
time, and the
MV is
refreshed. If T
S
is less than 1, it
will be count as
1. If T
S
is larger
than 2000, it
will be count as
2000. When
the instruction
PID is used in
the interval
interrupt task,
the sampling
time is the
same as the
