Component	Description
Alarm state	Displays the present state of the alarm. For more information, see Alarm States .
Basic evaluation state	Displays False when the alarm is in its normal state.
Evaluation state	Displays the present evaluation state of the alarm. For example, Upper limit alarm is displayed when the monitored value reaches the upper alarm limit.
Disabled cause	Displays the cause for the alarm being disabled: Shunt variable means that the alarm has been disabled by a shunt variable User means that the alarm has been disabled by the user System means that the alarm has been disabled by the system
Monitored variable	Enter the path to the variable that is monitored by the alarm.
Reference variable	Enter the reference variable that is compared with the monitored variable.
Upper deviation limit	Enter the highest value the monitored variable can increase to before the alarm is triggered.
Lower deviation limit	Enter the lowest value the monitored variable can decrease to before the alarm is triggered.
Deadband	Enter the range the monitored variable has to pass within the normal range before the alarm is reset. For more information, see Deadband .
Reset delay (s)	Enter the time, in seconds, the alarm has to be within the reset criteria before the alarm state is changed from alarm to reset. For more information, see Time Delay .
Alarm delay (s)	Enter the time, in seconds, the alarm has to be within the alarm criteria before the alarm is triggered. For more information, see Time Delay .
Shunt variable 1	Enter the shunt variable that is used to enable or disable the alarm. For more information, see Shunt Variables .
Invert shunt value 1	Select to invert the shunt value, that is, enable the alarm when the shunt value is active and disable the alarm when the shunt value is inactive. For more information, see Shunt Variables .
Shunt operator	Select AND or OR to add logic between the first and the second shunt variable. For more information, see Shunt Variables .
Shunt variable 2	Enter the second shunt variable that is used to enable or disable the alarm. For more information, see Shunt Variables .
Invert shunt value 2	Select to invert the shunt value, that is, enable the alarm when the shunt value is active and disable the alarm when the shunt value is inactive. For more information, see Shunt Variables .

Component

Description

Alarm state

Displays the present state of the alarm. For more information, see Alarm States .

Basic evaluation state

Displays False when the alarm is in its normal state.

Evaluation state

Displays the present evaluation state of the alarm. For example, Upper limit alarm is displayed when the monitored value reaches the upper alarm limit.

Disabled cause

Displays the cause for the alarm being disabled:

Shunt variable means that the alarm has been disabled by a shunt variable
User means that the alarm has been disabled by the user
System means that the alarm has been disabled by the system

Monitored variable

Enter the path to the variable that is monitored by the alarm.

Reference variable

Enter the reference variable that is compared with the monitored variable.

Upper deviation limit

Enter the highest value the monitored variable can increase to before the alarm is triggered.

Lower deviation limit

Enter the lowest value the monitored variable can decrease to before the alarm is triggered.

Deadband

Enter the range the monitored variable has to pass within the normal range before the alarm is reset.

For more information, see Deadband .

Reset delay (s)

Enter the time, in seconds, the alarm has to be within the reset criteria before the alarm state is changed from alarm to reset.

For more information, see Time Delay .

Alarm delay (s)

Enter the time, in seconds, the alarm has to be within the alarm criteria before the alarm is triggered.

For more information, see Time Delay .

Shunt variable 1

Enter the shunt variable that is used to enable or disable the alarm. For more information, see Shunt Variables .

Invert shunt value 1

Select to invert the shunt value, that is, enable the alarm when the shunt value is active and disable the alarm when the shunt value is inactive. For more information, see Shunt Variables .

Shunt operator

Select AND or OR to add logic between the first and the second shunt variable. For more information, see Shunt Variables .

Shunt variable 2

Enter the second shunt variable that is used to enable or disable the alarm. For more information, see Shunt Variables .

Invert shunt value 2

Select to invert the shunt value, that is, enable the alarm when the shunt value is active and disable the alarm when the shunt value is inactive. For more information, see Shunt Variables .
