Description

Alarm state

Displays the present state of the alarm. Более подробную информацию см. 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 when variable is

Select the statuses of the monitored variable that trigger the alarm.

Forced means that the alarm is triggered when the monitored variable status is forced. Более подробную информацию см. Force and Unforce Buttons .
Overridden means that the alarm is triggered when the monitored variable status is overridden. Более подробную информацию см. Output Override Status .
Offline means that the alarm is triggered when the monitored variable is off line.

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.

Более подробную информацию см. Time Delay .

Shunt variable 1

Enter the shunt variable that is used to enable or disable the alarm. Более подробную информацию см. 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. Более подробную информацию см. Shunt Variables .

Shunt operator

Select AND or OR to add logic between the first and the second shunt variable. Более подробную информацию см. Shunt Variables .

Shunt variable 2

Enter the second shunt variable that is used to enable or disable the alarm. Более подробную информацию см. Shunt Variables .
