Opening SmartServer Applications
The SmartServer includes the following set of built-in apps that let you monitor and control devices:

Alarm Generator and Alarm Notifier. The SmartServer can trigger alarms based on inputs from
the devices it is attached to. In response to an alarm condition, the SmartServer can be configured
to update L
ON W ORKS , Modbus, and M-Bus data points; log the conditions to one or more data
logs; or send out e-mails or SOAP messages notifying recipients of the alarms and the conditions
that triggered them. You can configure alarms to shut off automatically when certain conditions
are met or they can be configured to require manual clearance in the SmartServer Web pages. The
alarming applications are described in Chapter 6, Alarming.

Scheduler. The SmartServer can be used to update any data points based on the time-of-day,
day-of-week, and date. These schedules can drive the inputs to any data point including
L
ON W ORKS , Modbus, and M-Bus data points. The Event Scheduler includes an astronomical
position sensor that you can use to calculate the position of the sun based on the location of the
SmartServer and the time-of-day. This is useful for calculating whether it is light or dark outside
without using an external light-level sensor, and it is ideal for applications such as street lighting,
where lights need to turn on at sundown and turn off at sunrise. This application is described in
Chapter 7, Scheduling.

Data Logger. The SmartServer can log L ON W ORKS , Modbus, and M-Bus data points. These logs
can be downloaded automatically using the new fast data log transfer feature, or they can be
downloaded manually using File Transfer Protocol (FTP), retrieved using a SOAP/XML Web
service, or displayed with the Data Logger: View Web page. This application is described in
Chapter 8, Data Logging.

Pulse Meter, Digital Input, Digital Output. The SmartServer contains two built-in pulse metering
inputs, two built-in digital inputs, and two built-in digital relay outputs. You can use these inputs
and outputs to connect legacy devices to the SmartServer. You can use the Pulse Metering
application to have the SmartServer count pulses or to measure the pulse frequency from pulse
output devices. You can use the Digital Input and Digital Output applications to monitor and
control simple sensors and actuators that can be connected to the SmartServer such as switches,
push buttons, alarms, and drive contractors. These applications are described in Chapter 9,
Connecting Legacy Devices to the Local i.LON Inputs and Outputs.

Analog Functional Block. The SmartServer contains an Analog Functional Block application that
you can use to perform a variety of arithmetic and logical operations on a set of data points, and
then store the result of the operation in an output data point. This application is described in
Chapter 10, Using Analog Functional Blocks.
