Visualizing Alarm Management

In CODESYS, the alarm management is a powerful object for creating and managing alarms. You can group alarms and set the acknowledgement behavior individually. The alarm display can also be customized in the visualization.

The Alarm table and Alarm banner visualization elements are available for displaying and processing alarms. The alarm table lists the alarm texts. The alarm banner is a simplified version of the alarm table. It visualizes a single alarm only.
