Overview – .NET Alarm

The OAS Alarm .NET product provides the features of viewing real-time and historical alarms on unlimited local and remote systems, alarm logging, alarm notification, and alarm statistics.

This product includes the windows services to monitor alarm limits, a .NET component to be used on local and remote systems to connect to the local windows service.

Alarming can be enabled to monitor both analog and digital signals with fixed, adjustable, and tracking alarm limits.

Alarm limits can be defined for high high, high, low, low low, rate of change, and digital alarms.

The first step is to define the Alarm Limits. This is demonstrated in the Quick Start Section under Configure Tags – Alarm Limits.

Alarm Limits are also demonstrated in the Alarm Limits video.

The next step is determine how you want to present the alarm to the user.

Users can view what is currently in alarm and history of alarms in both Windows and Web versions of the alarm windows. Both support Internet communications as well.

For Smart phones the Web Alarm Window is the right choice. For Windows and WPF applications the Windows Alarm Window is the one to use.

If you do not want to develop an application and just want to trend window to display your data you can use the OPC Trends and Alarms Dashboard.
