Overview – Alarm Notification
The OAS Alarm Notification feature is included as part of the Alarms .NET and Web Alarms products. If you want to develop server or desktop applications using WinForms, WPF or the Dotnet SDK then you would choose the Alarms .NET product. On the other hand, if you want to develop web-based applications with HTML and JavaScript the you would choose the Web Alarms product.
Both products give you the ability to configure alarm thresholds on any of your tags. This includes Digital, Low, Low Log, High, High High and Rate of Change alarm types with configurable parameters such as threshold value, delay, deadband, priority, alarm text, alarm group and more. By default, OAS stores the run-time alarm state in memory and allows you to configure alarm buffering in case of restart. OAS also provides alarm acknowledgement features through the alarm controls and its APIs.
The Alarm Notification feature allows you to send alarm notifications via E-mail, SMS or Voice. E-mail notifications are configured to send using an SMPT server. The SMS and Voice notifications are integrated with Twilio and require a Twilio account.
Alarm notifications work by configuring one or more Notification Groups. Each notification group is essentially a filter and any alarms that match the filter will trigger a notification for that alarm. This includes parameters such as alarm state, alarm type, priority and alarm group. You can create as many notification groups as you need.
Supported features:
- Customize which alarm details are included
- Dynamically set “To Address” using another Tag
- Dynamically set “Phone Number” using another Tag
- Repeat notification after time delay
- Prevent sending multiple notifications within configurable time period
- Acknowledge alarm by E-mail reply
