Concept
Alarm Types
An alarm compares the value from a monitored variable with the conditions of the alarm. Different types of alarms handle different types of variables and different forms of evaluation.
Alarms can monitor values from external sources, such as LonWorks and BACnet devices, as well as values from EcoStruxure BMS servers. Some alarms are also based on system information, such as device restart or network status.
Change of State Alarms
The change of state alarm monitors the state changes of digital variables. You configure the alarm to trigger when the variable changes its state to true or to false.

Out of Range Alarms
When setting up an out of range alarm, you configure the normal range of the monitored variable. If the variable goes below the lower limit or above the upper limit of the normal range, the alarm is triggered.

Out of Reference Range Alarms
The out of reference range alarm monitors variable movements comparing to a reference variable. By setting an upper deviation limit and lower deviation limit, you configure the tolerance the monitored variable can vary from the reference variable before the alarm is triggered. The upper alarm limit of the monitored variable is equal to the reference point current value plus the upper deviation limit. The lower alarm limit of the monitored variable is equal to the reference point current value minus the lower deviation limit.

Multistate Alarms
The multistate alarm monitors a variable and triggers the alarm if the variable is between the configured alarm range or equal to a single value. You can add several ranges or single values to trigger the alarm.

Matching Text String Alarms
A matching text string alarm evaluates if the monitored value equals the given text strings.

Variable Status Alarms
The variable status alarm monitors the status of a variable. The alarm is triggered when the value of the monitored variable is either forced or overridden. If you configure the alarm to trigger on both force and override, the alarm is triggered immediately when the variable changes to one of the two statuses.

Sum Alarms
A sum alarm can be seen as a collection of alarms that have one or several common denominators. The conditions you use to filter which alarms the sum alarm monitors are the same conditions you use to filter the Alarms pane or an Alarm View. You can use wildcards when setting up filter conditions. Pour plus d'informations, voir Filter Condition Wildcards .

Enumeration Alarms
An enumeration is a variable with labeled values; different variables have different enumerations. When configuring an enumeration alarm, you configure the variable and its enumerations to monitor.

System Alarms
System alarms monitor system entities, such as online status for field servers or field devices. The system alarms are generated by the EcoStruxure Building Operation software. Users cannot create new system alarms. The possible causes of a system alarm are gathered in an enumeration called System alarm ID. When a system alarm is triggered, the cause of the alarm is indicated in the System alarm ID column in the Alarms pane or Alarm View. Some system alarms have additional information in the Alarm text column.

EcoStruxure Web Service Alarm Item
The EcoStruxure Web Service alarm item is a representation of an alarm on an EcoStruxure Web Service. The alarm item is automatically created when you host an EcoStruxure Web Service alarm on your system.
