Description Values
CV3WindupLOut BOOL CV3 Windup low indicator.
CV3WindupLOut is set to true when
• SP1LAlarm or SP2LAlarm is true or
• ModelGain is positive and CV3LAlarm is true or
• ModelGain is negative and CV3HAlarm is true.
This signal will typically be used by the WindupLIn
input to limit the windup of the CV3 output on a
primary loop.
ProgOper BOOL Program/Operator control indicator. TRUE when in
Program control. FALSE when in Operator control.
CV1Auto BOOL Auto mode indicator for CV1. TRUE when CV1 in the
Auto mode.
CV2Auto BOOL Auto mode indicator for CV2. TRUE when CV2 in the
Auto mode.
CV2Auto BOOL Auto mode indicator for CV3. TRUE when CV3 in the
Auto mode.
CV1Manual BOOL Manual mode indicator for CV1. TRUE when CV1 in
the Manual mode.
CV2Manual BOOL Manual mode indicator for CV2. TRUE when CV2 in
the Manual mode.
CV3Manual BOOL Manual mode indicator for CV3. TRUE when CV3 in
the Manual mode.
CV1Override BOOL Override mode indicator for CV1. TRUE when CV1 in
the Override mode.
CV2Override BOOL Override mode indicator for CV2. TRUE when CV2 in
the Override mode.
CV3Override BOOL Override mode indicator for CV3. TRUE when CV3 in
the Override mode.
CV1Hand BOOL Hand mode indicator for CV1. TRUE when CV1 in
the Hand mode.
CV2Hand BOOL Hand mode indicator for CV2. TRUE when CV2 in
the Hand mode.
CV3Hand BOOL Hand mode indicator for CV3. TRUE when CV3 in
the Hand mode.
DeltaT REAL Elapsed time between updates in seconds.
CV1StepSizeUsed REAL Actual CV1 step size used for tuning.
CV2StepSizeUsed REAL Actual CV2 step size used for tuning.
CV3StepSizeUsed REAL Actual CV3 step size used for tuning.
CV1PV1GainTuned REAL The calculated value of the internal model gain for
CV1 - PV1 after tuning is completed.
CV2PV1GainTuned REAL The calculated value of the internal model gain for
CV2 - PV1 after tuning is completed.
CV3PV1GainTuned REAL The calculated value of the internal model gain for
CV3 - PV1 after tuning is completed.
CV1PV2GainTuned REA: The calculated value of the internal model gain for
CV1 - PV2 after tuning is completed.
