Group - tab of the PmaAlarmGroup object

Basic parameters of an alarm group.
Alarm group identifierThe unambiguous identifier of an alarm group in the application.
Displayed group nameThe displayed name of an alarm group. It is used in viewers, print-outs, etc. The name doesn't need to be entered (can be empty string) - in this case the group name is not displayed anywhere. It has sense only if there is only one alarm group in the application.
AreaMarking the area where the alarm group belongs (group or subgroup).
All alarm items of one PmaAlarmGroup object belong to the same area.
It goes about an arbitrary string that allows to users easier filtering the set values when watching the group.
It is useful first of all if more Group objects store the data to the common file (see the "Parent enabled" configurator).
State viewerPath to registered #state viewer represented by PmaPanel with PmgAlarmStateViewer object.
If not set then no registered viewer is set for this alarm group.
History viewerPath to registered #history viewer represented by PmaPanel with PmgAlarmHistoryViewer object.
If not set then no registered viewer is set for this alarm group.
Remote group (client)If checked, then the group is not meant for generating alarm items but it serves only for the remote viewing another alarm group. All operations that would have resulted in writing to disk, will fail over such group.
Number of inactive, unacknowledged older copies of the (blue) alarmThe configurator specifies the maximum number of inactive, unacknowledged (blue) copies for each alarm.
If it is zero, then the copy is not created.
If it is non-zero, then when an alarm is triggered that is inactive unacknowledged [blue] this alarm is activated (it becomes active unacknowledged [red]), but at the same time a copy of the alarm in the original (blue) state is created, so that both alarms are visible in the alarm state viewer at the same time.
After this copy is acknowledged, the copy is removed automatically.
Change inactive acknowledged (green) CEASED to NEW non-initialized alarms in [s] (-1=never)The configurator sets/disables the time delay in seconds, before the inactive acknowledged (green) CEASED alarms are automatically switched to inactive acknowledged (green) NEW non-confirmed alarms.
The -1 value disables the automatic switching.
Hide inactive acknowledged (green)It allows to define whether to display inactive acknowledged (green) alarms.
Inactive acknowledged (green) alarms can be divided into two types. New, non-initialized (non-existing so far) alarms and alarms that have been active in the past, but ceased existence.
0 = Show all - Inactive acknowledged (green) alarms will all be displayed, i.e. alarms of both types (i.e. both new and expired alarms will be displayed).
1 = Hide all - Inactive acknowledged (green) alarms will not be displayed (i.e. no new and no expired alarms will be displayed).
2 = Hide only new non-initialized - Inactive acknowledged (green) alarms of the new non-initialized type (not activated so far) will not be displayed. Inactive acknowledged (green) alarms that have been active in the past and are ceased now, will be dispayed (i.e. new alarms will not be displayed, ceased alarms will be displayed). See the "PmaAlarmGroup > Group > Change inactive acknowledged (green) CEASED to NEW non-initialized alarms in [s] (-1=never)" configurator.
Delete inactive acknowledged (green) (valid only for dynamically created items)If checked, then the alarm item is removed from the list if it becomes inactive and acknowledged at the same time (see the state inactive acknowledged [green]). It has sense only for dynamically created alarm items. The same value can be set even for alarm item templates, see the "Delete inactive acknowledged (green)" configurator.
Sound notificationThe way of sound indication of an alarm items state.
0 = no sound
1 = sound stops after acknowledgment or inactivate
2 = sound stops after acknowledgment and inactivate
3 = sound stops after acknowledgment
Sound parametersParameters entered here can be modified by any PmAlarmItem object.
Parent enabledIf checked, then the parent group can be set in the "Parent" configurator.
Parentalarm items (PmAlarmItem objects) arise and are stored to disk in the parent group. alarm groups are displayed in the state viewer or in the history viewer also in this parent group. Filtering in the viewer according to the "Area" configurator allows to display items only of the certain alarm group in the frame of the parent group.
Enable alarm storage at short application shutdownIf checked, then all active alarms are automatically saved to disk (when the application is stopped) into the #data:GroupId.alb file, where GroupId represents the alarm group identifier.
When starting the application, if the shutdown time does not exceed the configured time and the application has not been edited, stored active alarms will be automatically re-created with the original information (status, time of origin, acknowledgment time, etc.).
The memorized alarms are created immediately after the alarm group is created at application launch, before any alarm can occur in the application. If later, when an alarm occurs and it is determined that it has already been created by reading from the file, then it will be associated with this memorized alarm (no additional will be created). This applies to both in the script and alarms from data extension. This concept allows you to achieve "existence" of active alarms while briefly turning off the application, so neither in states nor in alarm history you will not be able to see that the alarm actually disappeared when the application was stopped and that it was triggered by running the application again. After the application is launched, the file will be deleted.
Maximum time of application shutdown [s]Maximum allowed application shutdown time period in seconds (i.e. the "age" of the file) after which the stored alarms will be recreated from the file at application launch. (-1 = unlimited)
