R/W O BIAS
Feedforward output value, used for
the PID feedforward.

R/W X MV
The MV output value is K0~K1000
and the unit is 0.1.

Accumulated integral value
temporarily stored is usually for
reference. Users can still clear or
modify it according to their needs.
When the MV is greater than the
MV_MAX, or when the MV is less
than MV_MIN, the accumulated
integral value in I_MV is

Calculated proportional coefficient
(Kc or Kp)
If the P coefficient is less than 0,
the Kc_Kp will be 0. Independently,
if Kc_Kp is 0, it will not be
1.0

Integral coefficient (Ti or Ki）
If the calculated coefficient I is less
than 0, Ti_Ki will be 0. If Ti_Ki is 0,
it will not be controlled by I.

Derivative coefficient (Td or Kd)
If the calculated coefficient D is less
than 0, Td_Kd will be 0. If Ti_Ki is
0, it will not be controlled by D.
0.1

Derivate parameter for suppressing
variations can filter derivatives,
which would be more effective with
greater parameter values.
Generally it is suggested to use the
