The "AlarmLineCollection" is used to display alarms in an alarm line. The "AlarmLineItems" property in the "AlarmItems" category can be used to configure how many different alarm categories are to be displayed in the alarm line. The alarm classes to be displayed (e.g. system alarm, alarm) can be entered for each AlarmLineItem in the "DesiredAlarmClasses" property under "Alarms".

AlarmLineCollection and its components

The control element supports the following functionality:

Connection to an analogue process variable(integer value/floating point value) for the data source
Clear visualisation of alarms of different alarm classes
Expansion of the alarm line to display further options
Color display of the background, frame, text, etc., also depending on the status of the control element

The AlarmLineCollection is available in the following styles: Lenze.Default, LenzeCyan.Default, Custom.Default.

The "AlarmLineCollection" and its elements

The "AlarmLineCollection" contains one or more "AlarmLineItems", each of which represents a filter for alarms of defined alarm classes via the "DesiredAlarmClasses" property. The "AlarmLineCollection" can be expanded at runtime using the "Dropdown enabled" property under Options. This additional area contains all pending alarms of the selected alarm classes and the three additional buttons User-defined, Close and Acknowledge all. The custom button can be linked to an action via the ControlEventTrigger with the event name "onCustomClick". In the template, an AlertDialogue is opened here as an example. The Acknowledge button is linked by default to the AcknowledgeAlarmsAction, which acknowledges all currently pending alarms of the alarm classes or groups specified in the action at once. The Close button closes the expanded view. The appearance of the buttons can be configured in the styling view of the "AlarmLineCollection".
