*Alarming

Alarming can be implemented for real-time and historical alarms.

The first step is to define the alarm limits using the Configure OPC Systems application under Configure-Tags.

View the following 7 minute video on how to define the alarm limits in more detail.

You can then define alarm windows, alarm logging, and alarm notification.

Alarm applications can be developed for standard Windows WinForm applications, Window Presentation Foundation applications, or web applications.

Windows WinForm Alarming applications are the most compatible with operating systems ranging from Windows 2000, XP, Server 2003, Server 2008, Vista, and Windows 7.

WPF Alarming applications provide the best user experience to got with your WPF HMI application for Vista and Windows 7 operating systems.

Web Alarming applications provide user interfaces for smartphones like the iPhone and Droid cell phones, and for non-Windows operating systems like the iPad.

You can also use OPC Alarm.NET in the OPC Trends and Alarms container without using Visual Studio if you prefer not to create any applications.

The OPC Alarm.NET component can be integrated directly into any .NET container, most commonly Visual Studio.NET. or the OPC Trends and Alarms container.

The OPC Alarm ActiveX control can be integrated directly into any ActiveX container, most commonly HMI graphic applications or Visual Studio 6.0.  Refer to Configure Alarm ActiveX section of Quick Start for an example if you need to use trending in an old Visual Studio 6.0 application.
