Signal Alarm List at run-time
Fully customizable and easy to use, the HTML Alarm Manager provides you with the possibility to view, acknowledge, filter, and export your alarms, while at run-time.
After preparing the Signal Alarm List extension as described in the Signal Alarm List at design-time chapter, the Signal Alarm List i4scada SmartEditor project is ready to be published.
The Signal Alarm List extension can show the alarm status which belongs to the signal, having the possibility to change the alarm processing and display mode.
The Signal Alarm List extension
After publishing the i4scada SmartEditor extension "wf-signal-alarm-list" the visual structure features the following sections:
The Signal Alarm List toolbar

Refresh - updates the Signal Alarm List, when the online mode is paused.
Configuration Manager - opens the dialog with the same name, where the user can save and reuse Filter and Time settings. The Configuration Manager dialog is split up into three tabs:
