Alarms Menu - FDM121 User Guide

Definitions

An event is a digital data changing state or any incident detected by the modules of the IMU. Events are time-stamped and logged in the module event history.

An alarm is a type of event that requires a specific attention from the user.

The user can associate an alarm with any measurement or event in the IMU.

Each alarm is given a pre-defined priority level:

High priority
Medium priority
Low priority
No priority

The user can set the alarm parameters and assign priorities with EcoStruxure Power Commission software.

For more information about alarm setup and priorities, refer to the MicroLogic Trip Units User Guides provided in the section Related Documents.
