Component

Description

Alarm state

Displays the present state of the alarm. Para obtener más información, consulte 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.

Trigger value

Select True to trigger the alarm when the monitored value changes to true.

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.

Alarm delay (s)

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

Para obtener más información, consulte Time Delay .

Shunt variable 1

Enter the shunt variable that is used to enable or disable the alarm. Para obtener más información, consulte 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. Para obtener más información, consulte Shunt Variables .

Shunt operator

Select AND or OR to add logic between the first and the second shunt variable. Para obtener más información, consulte Shunt Variables .
