Alarm

In the Alarm page of the Dashboard, you can configure alarm rules to monitor Data Source tags. When these tags reach or trigger the conditions you set, the Alarm Display widget on the Dashboard will trigger an alarm. Additionally, you can also view alarm history on the same page to track and review past alarm events. This design is intended to help you promptly identify and address potential issues, ensuring the stable operation of the system.

First, select the specified HMI, then add an alarm rule to monitor the Data Source tag.
