_7
Operand Data type Function Setting range Description
False: Automatic
Output the MV according to the
PID algorithm.
MOUT_AUTO BOOL
MOUT automatic
change mode
True: Automatic
MOUT varies with the MV.
False: Normal
MOUT does not vary with the
MV.
AUTO_DBW DWORD/DINT
Range within
which the auto
tuning is not
working
0~32000
Used when the
mode is set to auto
tuning, within the
range of SV ± dead
band, the auto
tuning is not
working.
Kc_Kp REAL
Calculated
proportional
coefficient (Kc or
Kp, according to
the settings in
PID_EQ)
Range of
positive single-
precision
floating-
point numbers
If the P coefficient is
less than 0, the
Kc_Kp is 0.
Independently, if
Kc_Kp is 0, it is not
controlled by P.
Ti_Ki REAL
Integral coefficient
(Ti or Ki, according
to the settings in
PID_EQ)
Range of
positive single-
precision
floating-
point numbers
(unit: Ti = sec;
Ki = 1/sec)
If the calculated
coefficient I is less
than 0, Ti_Ki is 0. If
Ti_Ki is 0, it is not
controlled by I.
Td_Kd REAL
Derivative
coefficient (Td or
Kd, according to
the settings in
PID_EQ)
Range of
positive single-
precision
floating-
point numbers
(unit: sec)
If the calculated
coefficient D is less
than 0, Td_Kd is 0.
If Ti_Ki is 0, it is not
controlled by D.
