CV2LLimit

<

CV2HLimit

100.0.

The default value is 100.0.

Enter the control variable CV3 high limit value.

This is used to set the

CV3HAlarm

CVManLimiting

is TRUE.

Valid values are in the range of

CV3LLimit

<

CV3HLimit

100.0.

The default value is 100.0.

Enter the control value CV1 low limit value.

This is used to set the

CV1LAlarm

output. It is also used for limiting CV1 when in Auto mode or Manual mode if

CVManLimiting

is TRUE.

CV1LLimit

<

CV1HLimit

.

The default value is 0.0.

Enter the control value CV2 low limit value.

This is used to set the

CV2LAlarm

output. It is also used for limiting CV2 when in Auto mode or Manual mode if

CVManLimiting

is TRUE.

CV2LLimit

<

CV2HLimit

.

The default value is 0.0.

Enter the control value CV3 low limit value.

This is used to set the

CV3LAlarm

output. It is also used for limiting CV3 when in Auto mode or Manual mode if

CVManLimiting

is TRUE.

Valid values are in the range of 0.0

CV3LLimit

<

CV3HLimit

.

The default value is 0.0.

Enter the CV1 rate of change (ROC) limit, in percent per second.

ROC limiting is only used when in Auto mode or Manual modes if

CVManLimiting

is TRUE. A value of zero disables CV1 ROC limiting.

Valid values are in the range of 0.0 to a maximum positive floating point value.

The default value is 0.0.

Enter the CV2 rate of change (ROC) limit, in percent per second.

ROC limiting is only used when in Auto mode or Manual modes if

CVManLimiting

is TRUE. A value of zero disables CV2 ROC limiting.

Valid values are in the range of 0.0 to a maximum positive floating point value.

The default value is 0.0.

Enter the CV3 rate of change (ROC) limit, in percent per second.

ROC limiting is only used when in Auto mode or Manual modes if

CVManLimiting

is TRUE. A value of zero disables CV3 ROC limiting.

Valid values are in the range of 0.0 to a maximum positive floating point value.

The default value is 0.0.

Enter the CV1 rate of change (ROC) limit, in percent per second.

ROC limiting is only used when in Auto mode or Manual modes if

CVManLimiting

is TRUE. A value of zero disables CV1 ROC limiting.

Valid values are in the range of 0.0 to a maximum positive floating point value.

The default value is 0.0.

Enter the CV2 rate of change (ROC) limit, in percent per second.

ROC limiting is only used when in Auto mode or Manual modes if

CVManLimiting

is TRUE. A value of zero disables CV2 ROC limiting.

Valid values are in the range of 0.0 to a maximum positive floating point value.

The default value is 0.0.

Enter the CV3 rate of change (ROC) limit, in percent per second.

ROC limiting is only used when in Auto mode or Manual modes if

CVManLimiting

is TRUE. A value of zero disables CV3 ROC limiting.

Valid values are in the range of 0.0 to a maximum positive floating point value.

The default value is 0.0.

Select this check box to limit CV1, CV2, or CV3 values in Manual mode request.

If

Manual

mode and

CVManLimiting

are TRUE, CV1, CV2, and CV3 are limited by the appropriate CV1, CV2, and CV3 HLimit and LLimit values.

Displays status information for blocks containing status bits. If none of the status bits are set, an

OK

message appears in this field. Otherwise, a list of the status bits that are set appears here. This list is comprised of the parameter names associated with the status bits, and typically explain which parameters were configured with invalid values.

Displays the block's execution number if the routine is in a verified state. If the routine is not yet verified, a

Routine not verified

message appears. Note that this item is read-only.

Select this check box if you do not want the description to display in the routine.
