Introduction to the Alarms Module
The Alarms Module is an indispensable tool to manage and regulate notification events, providing precise alerts for critical events and archiving data for subsequent analysis.

Purpose and Key Concepts
Below is a list of key concepts essential to understanding the Alarms Module.
Alarm Item
An Alarm Item is a tag or expression monitored by the Alarms module. It contains information such as the tag name, the alarm condition (the trigger of the alarm), and the associated Alarm Group. Each Alarm Item can have its configuration properties, such as Limit, Deadband, and Message, that define the alarm behavior and characteristics.
Alarm Group
An Alarm Group is a collection of Alarm Items with common properties and characteristics. Each Alarm Group can have configuration properties, such as Ack Required, Auto Ack Time, and Sound, that apply to all its Alarm Items.
Alarm Area
An Alarm Area is a hierarchical grouping of Alarm Group that allows for a more organized and structured approach to managing alarms. An Alarm Area can have a child Alarm Area, allowing for a hierarchical structure of Alarm Group and Alarm Items.
Audit Trail
The Audit Trail is a feature of the Alarms Module that logs all changes made to the Alarm Group and Alarm Item, including creation, modification, and deletion events. It is a way to track and record the history of changes made to the alarm configuration, providing a clear audit trail of who made what changes and when.
Alarms Functionality
The Alarms Module is crucial for real-time monitoring and immediate notification of events, continuously assessing tag values to detect when predefined limits or conditions are met and generating alarms accordingly. It ensures swift identification and response to critical events, enhancing flexibility and control in managing alarms.
Features Highlights
The Alarms Module offers the following key features:
- The Alarm Historian allows the Alarms module to save alarms and their state changes in a separate database. It differs from the Audit Trail, which only saves when editing the settings.
- The Alarm Window object displays active alarms and their state changes on display.
- Real-time alarm processing to quickly identify and respond to critical events.
- Hierarchy organization and management of alarms for greater flexibility and control.
- It considers universal time and daylight saving time for accurate timestamps.
- Dynamic language localization of alarm messages for easy understanding.
- High-precision timestamps up to 0.1ms for accurate and reliable data.
