Use Alarm Redirection to Send Alarm Details in an E-Mail

This example demonstrates how alarm redirections might be cascaded on a ClearSCADA system.

Two alarm redirections on a channel are configured to send alarm details in an e-mail. The first alarm redirection sends the e-mail to an engineer. If the engineer does not acknowledge the alarm within 10 minutes, a second alarm redirection is used to redirect the alarm to the engineer’s manager.

Example:

A channel is configured to provide a connection between the ClearSCADA server and a PLC. The channel is configured so that if communications via the channel is interrupted, a High priority alarm is raised. An Alarm Redirection is used to redirect the High priority alarm to an engineer. The first Alarm Redirection for the channel is configured as:

Trigger Type: Auto
Trigger State: Unacknowledged Uncleared
Action: ‘Communications Interruption’ E-mail (this is an e-mail to an engineer).
Low Severity: High
High Severity: High
Direction: Not Dependent On Direction (This setting is ignored by ClearSCADA, as the redirection is not for a point)
Delay: 0
Abort State: Never
Active From: 00:00
Active To: 00:00

With this configuration, as soon as an Unacknowledged Uncleared alarm with High priority is raised for the channel, ClearSCADA redirects the alarm by sending details of the alarm in the ‘Communications Interruption’ e-mail. The configuration of the ‘Communications Interruption’ E-mail Action determines which engineer receives the e-mail.

If the engineer does not acknowledge the alarm within 10 minutes, a second Alarm Redirection is used to redirect the alarm to the engineer’s manager. The second Alarm Redirection for the channel is configured as:

Trigger Type: Auto
Trigger State: Unacknowledged Uncleared
Action: ‘Communications Interruption - Unacknowledged’ E-mail (an e-mail to the engineer’s manager)
Low Severity: High
High Severity: High
Direction: Not Dependent On Direction (This setting is ignored by ClearSCADA, as the redirection is not for a point)
Delay: 10M
Abort State: Acknowledged
Active From: 00:00
Active To: 00:00

With this alarm redirection, when the channel has an Unacknowledged Uncleared alarm with High priority, a 10 minute timer begins. If the engineer does not acknowledge the alarm during the 10 minute delay, the alarm is redirected—the ‘Communications Interruption - Unacknowledged’ e-mail is sent to the engineer’s manager. If the engineer does acknowledge the alarm within the 10 minute delay, the alarm changes to an Acknowledged state, and the alarm redirection to the manager is canceled.
