Description Device number
is complete, the device is
automatically set to 0, and is filled in
with appropriate parameters Kc_Kp,
Ti_K , Td_K and Tf.
i d
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.
True: Automatic
The MOUT varies with the MV.
False: Normal
The MOUT deos not vary with
the MV.
When the
instruction is
scanned, the PID
algorithm is
implmented
according to the
sampling time, and
the MV is
refreshed. (PLC
will not use the
setting value to
determine the time
or to operate
1~40,000 automatically. ) If
(unit: ms) T is less than 1, it
S
will be counted as
1. If T
than 40,000, it will
be counted as
40,000. When the
instruction PID is
used in the interval
interrupt task, the
sampling time is
the same as the
interval between
the timed interrupt
tasks.
Range of It is a proportional
positive single gain. If a
precision proportional gain is
floating-point less than 0, Kc_Kp
values will be count as 0.
