An Alarm Item is essentially an alarm. It needs to be bonded to a numerical tag to monitor the variation range.
When opening the Alarm environment, the Items tab will load - by default only some of the columns will appear, with the basic Item configuration. By right-clicking on the header table you can see and check the other available columns.
The Alarms Items properties provide detailed configuration settings for individual alarms. This includes the unique identifier, condition specifications, value thresholds, associations to groups or hierarchies, and auxiliary data. Metadata such as creation and modification dates are also included to track changes over time. Messages and comments can be embedded to deliver relevant information during an alarm event.
