342 Alarming
Using the Alarm Notifier Application
The Alarm Notifier communicates alarms generated by application devices, including the SmartServer.
When a device transmits a SNVT_alarm or SNVT_alarm_2 output data point on the network or a
data point goes offline, the Alarm Notifier can send e-mail messages, update data points, and log alarm
conditions.
The Alarm Notifier reads the status of selected data points each time they are updated to determine if
their statuses have been changed to an alarm condition. If a data point is in an alarm condition, the
Alarm Notifier can send an e-mail message describing the alarm. If an e-mail profile is specified for
the Alarm Notifier, the e-mail message is sent to the addresses specified for that profile each time an
alarm notification occurs. This is useful if different groups need to receive notifications for specific
alarm conditions that may occur on your network. When a data point is in an alarm condition, the
Alarm Notifier can also update selected data points to specified values.
When the Alarm Notification sends an alarm notification, it creates and updates an Alarm Summary
log file that records all active alarms. By default, the file is located in the //AlarmLog folder on the
SmartServer flash disk and is named sumlog0. In addition, the Alarm Notifier creates an Alarm
History log file that records all alarm notifications. By default, this file is located in the //AlarmLog
folder on the SmartServer flash disk and is named histlog<x>, where x is the index number assigned to
the file when it was created. You can have the SmartServer automatically transfer the alarm log files
(binary or CSV format) to a remote server and extract the selected data to a .CSV or XML file.
Although the SmartServer does not limit how much alarm data can be logged, you must maintain at
least 1,024 KB of free space on the SmartServer flash disk. To view the amount of free disk space on
the SmartServer right-click the SmartServer point to Setup, and then click System Info on the shortcut
menu. The Setup – System Info Web page opens. In the General Statistics section, check the Free
disk space / Total disk space property.
You can create up to 40 Alarm Notifiers per SmartServer if you are using the default static v12
interface. You can add more than 40 Alarm Notifiers if you activate the dynamic v40 interface, which
features a dynamic external interface, on your SmartServer. See Activating the SmartServer V40 XIF
in Chapter 3, Configuring and Managing the SmartServer, for more information on loading the V40
XIF on the SmartServer.
To create an Alarm Generator, follow these steps:
1. Open an Alarm Notifier application.
2. Select and configure input points.
3. Configure alarm conditions.
4. Configure e-mail and data point destinations.
5. Configure the alarm summary and history log files stored on the SmartServer.
Opening an Alarm Notifier Application
To open an Alarm Notifier application, you must first create an Alarm Notifier functional block. After
you create the Alarm Notifier functional block, the functional block appears on the SmartServer tree
below the i.LON App (Internal) device, and you can click the functional block to open the Alarm
Notifier application.
To create an Alarm Notifier functional block and open the application, follow these steps:
1. Click General above the navigation pane in the left frame of the SmartServer Web interface.
2. Expand the network icon in the SmartServer tree, and then expand the LON channel to show the
i.LON App (Internal) device.
3. Right-click the i.LON App (Internal) device and then select Add Functional Block in the
shortcut menu.
