Alarm System

The alarm system has been improved with the following new features:

Impact Alarms

JTGO 4.0 introduces a new category of alarms, called impact alarms, which differ from existing raw alarms. Whereas raw alarms have a severity of type IltAlarm.Severity, impact alarms have a severity of type IltAlarm.ImpactSeverity. Without any further mention, the term `alarm' encompasses both raw and impact alarms.

New methods have been added to IltAlarm.State. Existing methods have been modified to access the specific raw and impact alarm counts, and the overall alarm counts. These API changes are detailed in Object State.

The following new business attributes have been added to IltObject for impact alarm counts:

newImpactAlarmCount: The number of new impact alarms.
impactAlarmCount: The number of impact alarms, both acknowledged and new.
newImpactAlarmHighestSeverity: The highest severity of new impact alarms.
impactAlarmHighestSeverity: The highest severity of impact alarms, both acknowledged and new.
ackImpactAlarmHighestSeverity: The highest severity of acknowledged impact alarms.

Predefined Alarm Business Object

A predefined business object for individual alarms has been created. It is embodied by the class IltAlarm.

Loss of Connectivity

JTGO 4.0 provides a new graphic representation for the alarm state Loss of Connectivity. The previous graphic representation is still valid and used by default. The new graphic representation is customized using the following CSS properties:

alarmLossOfConnectivityOverride: This property indicates whether the loss of connectivity state overrides the alarm information when building the object graphic representation. Its default value is true, meaning that, when the object has lost its connectivity, the object base is displayed with the loss of connectivity color even though alarms may be present in the object. If the value of the property is false, the alarm information is kept and the loss of connectivity is represented as an icon together with the other secondary state icons. When the object displays the information window, the loss of connectivity is listed with the other states.
