PROVUE Extended Alarms Configuration Items

The PROVUE EXTENDED ALARMS form is used to define up to four

alarms for a point. These alarms are local to the PROVUE console, and

are not related to the internal extended alarms for a UOC, IFC, or MUX.

Alarm No. Ċ This read-only field specifies the number of the alarm

being configured.

Alarm Type Ċ Specifies whether the alarm is a high alarm, low alarm, or

deviation alarm.

Alarm Word Ċ Identify what you want displayed on the console when

the extended alarm is active. Enter as many as 8 characters in this field.

Attr Ċ This configuration item specifies the attribute that will be

monitored. The valid attributes are:

H PV - Process Variable

H RA - Ratio Value

H SP - Set Point

H %BI- Percent Bias Value

H %OUTPUT - Percent output Value.

For deviation alarms either SP and PV may be entered, however, the

deviation is always calculated as the difference between those two

attributes. They may only be compared to each other, not to any other

attributes. Not all attributes are valid for all console point types.

Deadband Ċ Alarm deadband may be used to prevent unnecessary

alarm re-activation when the measured variable is close to the alarm trip

point. The value of the monitored attribute must move away from the trip

point towards the set point by more than the deadband before the alarm

will be cleared. The valid range is any positive floating point number.

Group No. Ċ Identifies the number of the alarm group that this alarm

group will be assigned. Valid range is 1 to 7 for P4.1 and earlier

PROVUE consoles, or 0 to 7 for P5.0 and later versions.

Trip / Dev Limit Ċ The deviation limit is the amount by which a value

must vary from the reference value to trigger a deviation alarm. The

valid range is any positive floating point number.
