Understanding Enbase Hub Alarms and Alarm Types

Learn how alarms work in Enbase HCP, the alarm types you may see, and how alarm states, arming behavior, and trigger conditions help you understand asset conditions.

Enbase alarms help identify when a monitored Tag reaches a condition that requires attention. Alarms are associated with Tags, which means the alarm is based on the value or status Enbase is receiving for that Tag.

Where Can I View Alarms?

In the Hub Control Panel, the Alarms View displays the current status of alarms configured on the Hub. The view provides information such as the associated Tag, alarm type, arming state, alarm state, trigger condition, and the most recent alarm details.

What Alarm Types Can I See?

The Hub Control Panel may display the following alarm types:

  • Limit
  • ValueChange
  • Rate
  • Unarmed: The alarm is not currently able to trigger.
  • NoAlarm: The alarm is armed and the Tag is currently in its normal condition.
  • WarningAlarm: The Tag has entered a configured warning condition.
  • CriticalAlarm: The Tag has entered a configured critical condition.
  • Immediate: The alarm can be armed immediately.
  • Timer: The alarm is armed after a configured delay.
  • Steady State: The alarm becomes armed after the Tag reaches a normal state.

A Limit alarm is used when a Tag value is evaluated against configured low or high thresholds. These thresholds may include LoLo, Lo, Hi, and HiHi.

A ValueChange alarm is used when a change in a Tag value or status should generate an alarm condition.

The Alarms View can also identify Rate alarms, which are associated with changes in a Tag value over time.

Understanding Alarm States

The Alarms View can show several alarm states:

Understanding Alarm Arming

An alarm can use different arming behavior depending on how the Tag is configured:

What Is a Trigger Condition?

The Trigger Condition indicates what caused the alarm state. Depending on the alarm configuration, you may see Normal, LoLo, Lo, Hi, HiHi, StatusChange, or RateChange.

Viewing Previous Alarm Events

If you need to understand what happened earlier, use Event History to review logged Alarm Events. Alarm history includes the Tag name, value when the alarm occurred, alarm state, trigger, time, and message.
