WindupHIn BOOL Windup high request. When TRUE, CV will
not be allowed to increase in value. This
signal will typically be the WindupHOut
output from a secondary loop.
Default = FALSE
WinduplIn BOOL Windup low request. When TRUE, CV will
not be allowed to decrease in value. This
signal will typically be the WindupLOut
output from a secondary loop.
Default = FALSE
GainEUSpan BOOL ModelGain units in EU or as % of span.
CV ModelGain units in EU or % of span. Set
to interpret ModelGain as EU, reset to
interpret ModelGain as % of Span.
Default = FALSE
TRUE = Gain in EU
FALSE = Gain in % of span
ProcessGainSign BOOL Used only for Autotuning. Sign of the
process gain (Delta PV/Delta CV).
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
ModelGain REAL The internal model gain parameter. Enter a
positive or negative gain depending on
process direction.
Valid = maximum negative
float −> maximum positive
float
Default = 0.0
ModelTC REAL The internal model time constant in
seconds.
Valid = 0.0 to maximum
positive float
Default = 0.0
ModelDT REAL The internal model deadtime in seconds. Valid = 0.0 to maximum
positive float
Default = 0.0
RespTC REAL The tuning parameter that determines the
speed of the control variable action in
seconds.
Valid = 0.0 to maximum
positive float
Default = 0.0
PVTracking BOOL SP track PV request. Set TRUE to enable SP
to track PV. Ignored when in CascadeRatio
or Auto modes.
Default = FALSE
CVTrackReq BOOL CV Track request. Set true to enable CV
Tracking when autotune is OFF. Ignored in
Hand and Override mode.
Default = FALSE
AllowCasRat BOOL Allow CascadeRatio mode permissive. Set
TRUE to allow CascadeRatio mode to be
selected by using either ProgCasRatReq or
OperCasRatReq.
Default = FALSE
ManualAfterInit BOOL Manual mode after initialization request.
When TRUE, the function block will be
placed in the Manual mode when
CVInitializing is set TRUE unless the current
mode is Override or Hand.
When ManualAfterInit is FALSE, the
function block's mode will not be changed.
Default = FALSE
