condition and then either hold down CTRL and click all the other alarm conditions to be moved or
hold down SHIFT and select another alarm condition to move the entire range of alarm conditions.
3. Optionally, you can click the Description property header to enter a description that will be stored
in the Alarm Summary and Alarm History logs when the alarm condition occurs.
4. Optionally, you can click the Level property header to set the priority to be assigned to the alarm
condition. You can later configure the Alarm Notifier in the Configure - Alarm Notifier -
Destinations Web page to respond to different alarm conditions based on the priority level they
have been assigned.
5. Click Submit.
6. In the Delay box ( ), you can enter the minimum period of time (between 0 to 65,536
seconds) that an alarm condition must exist for the alarm to be considered to be active. Setting a
delay can be useful. Using a temperature control system with backup heating and cooling systems
for example, you could set a 5-minute delay so that the backup systems could attempt to resolve
an alarm condition before the alarm is considered active and the Alarm Notifier sends an e-mail
notification.
7. Click Submit.
Configuring E-mail and Data Point Destinations
You can specify the e-mail recipients and customize the e-mail message for the e-mail notification sent
when an alarm condition is received by one of the selected input points. You can also select the data
points to be updated and set their values when an alarm condition is received.
1. In the Aggregation Time (e-mail) box ( ), you can enter the period of time
(between 0 to 65,536 ms) that the Alarm Notifier waits between generating and sending an e-mail
notification in order to merge multiple e-mail notifications to the same address into a single e-mail
message. Setting an e-mail aggregation period can reduce e-mail traffic. For example, if you have
a number of alarms in a system that trigger when the temperature reaches a certain point, setting
an e-mail aggregation time of a minute (60,000 ms) causes a single e-mail message to be sent in
the case of a system-wide temperature fluctuation, rather than multiple e-mail messages. The
e-mail aggregation period resets each time a new alarm occurs.
2. Click Submit.
3. Click any of the e-mail or data point icons above the Aggregation Time (e-mail) box. The
Alarm Notifier: Destination Web page opens.
Each row in the table represents an e-mail message and data point update (collectively referred to
as a destination) to be sent by the Alarm Notifier when an alarm notification event occurs. Each
destination is divided into two rows: the top row, which is marked with a red alarm bell, is for
active alarms; the bottom row, which is marked with a green alarm bell, is for passive alarms.
This setup enables active and passive alarms to be addressed separately.
