Introduction to Alarm Redirection

Alarm Redirection enables alarms to be redirected to engineers that are not manning a ClearSCADA workstation—for example, engineers that are on site. It also allows other actions, such as performing a one-shot call on an outstation, to be undertaken automatically when particular alarm situations occur.

The alarm redirection feature allows ClearSCADA to redirect an item’s alarms:

As an e-mail or voice message
As a pager or SMS (mobile telephone) text message
To perform an action on an item (known as invoking a method)
To alter the alarm’s severity
To restrict the ability to acknowledge an alarm
To execute a Windows® system command (for instance, to run an external application)
On a roster basis
On a calendar basis.

Alarm redirection is available for database items that can have alarms, including, for example, points, outstations, and channels. Each item can have up to 15 alarm redirections. However, if the item is in a Group, further alarm redirections can be applied on a group-wide basis, as the Group can also have alarm redirections.

Alarm redirections can be cascaded—if the alarm is redirected, and has not been dealt with within a defined time, the alarm can be redirected again, using a different redirection action.

This guide explains the considerations and Preparation that is required before configuring alarm redirections on a system. It also explains Setting up Alarm Redirections on a ClearSCADA System and includes detailed sections on how to:

It also explains the Trip Sequences Supported by Redirection Actions and Troubleshooting Redirection Action Trip Sequences.

NOTE: ClearSCADA can be configured to trigger a particular Method Action immediately, whenever an alarm state change occurs, regardless of the alarm priority or when the alarm changes state. If this is required, consider whether to configure a Method on the Alarm tab of a Form (see Configure a Method Action to Trigger at Every Alarm State Change in the ClearSCADA Guide to Core Configuration).
