Used only for Autotuning. Sign of the
process gain (Delta PV/Delta CV3).
Set to indicate a negative process gain
(increase in output causes a decrease
in PV).
Reset to indicate a positive process
gain (increase in output causes an
increase in PV).
Process type selection (1=Integrating,
0=non-integrating)
The internal model gain parameter for
CV1. Enter a positive or negative gain
depending on process direction.
The internal model gain parameter for
CV2. Enter a positive or negative gain
depending on process direction.
The internal model gain parameter for
CV3. Enter a positive or negative gain
depending on process direction.
The internal model time constant for
CV1 in seconds.
The internal model time constant for
CV2 in seconds.
The internal model time constant for
CV3 in seconds.
The internal model deadtime for
CV1 in seconds.
The internal model deadtime for CV2
in seconds.
The internal model deadtime for CV3
in seconds.
The tuning parameter that determines
the speed of the control variable
action for CV1 in seconds.
The tuning parameter that determines
the speed of the control variable
action for CV2 in seconds.
The tuning parameter that determines
the speed of the control variable
action for CV3 in seconds.
The first CV to act to compensate for
PV-SP deviation.
1=CV1, 2=CV2, 3=CV3
The second CV to act to compensate
for PV-SP deviation.
1=CV1, 2=CV2, 3=CV3
The third CV to act to compensate for
PV-SP deviation.
1=CV1, 2=CV2, 3=CV3
