CV3ProcessGainSign BOOL 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).
Default = FALSE
ProcessType DINT Process type selection (1=Integrating,
0=non-integrating)
Default = 0
CV1ModelGain REAL The internal model gain parameter for
CV1. Enter a positive or negative gain
depending on process direction.
Valid = maximum negative float −>
maximum positive float
Default = 0.0
CV2ModelGain REAL The internal model gain parameter for
CV2. Enter a positive or negative gain
depending on process direction.
Valid = maximum negative float −>

Default = 0.0
CV3ModelGain REAL The internal model gain parameter for
CV3. Enter a positive or negative gain
depending on process direction.
Valid = maximum negative float −>

Default = 0.0
CV1ModelTC REAL The internal model time constant for
CV1 in seconds.
Valid = 0.0 to maximum positive float
Default = 0.0
CV2ModelTC REAL The internal model time constant for
CV2 in seconds.
Valid = 0.0 to maximum positive float
Default = 0.0
CV3ModelTC REAL The internal model time constant for
CV3 in seconds.

in seconds.
Valid = 0.0 to maximum positive float
Default = 0.0
CV3ModelDT REAL The internal model deadtime for CV3
in seconds.
Valid = 0.0 to maximum positive float
Default = 0.0
CV1RespTC REAL The tuning parameter that determines
the speed of the control variable
action for CV1 in seconds.
Valid = 0.0 to maximum positive float
Default = 0.0

the speed of the control variable
action for CV2 in seconds.
Valid = 0.0 to maximum positive float
Default = 0.0
CV3RespTC REAL The tuning parameter that determines
the speed of the control variable
action for CV3 in seconds.
Valid = 0.0 to maximum positive float
Default = 0.0
Act1stCV DINT The first CV to act to compensate for
PV-SP deviation.
1=CV1, 2=CV2, 3=CV3
Valid = 1-3
Default = 1
Act2ndCV DINT The second CV to act to compensate
for PV-SP deviation.
1=CV1, 2=CV2, 3=CV3
