Instruction Manual

i.LON 100 Internet Server Programmer’s Reference 7-7

Property Description

Specifies the alarm priority that will be reported in the priority_level field

of the alarm data points for the Alarm Generator. The alarm priority is

independent of the alarm type. For a list of valid alarm priorities, see

Alarm Priority Levels on page 7-11.

The time period to wait after enabling or starting the application before

polling the value of the input data point. This field has a range of 0.0-

6553.0 seconds.

When the default value of 0.0 seconds is used, the Alarm Generator will

resume polling the input data point at the interval specified by the

<UCPTpollRate> property immediately after a reset.

The poll rate for the input and compare data points, in seconds. When this

value is greater than 0, the Alarm Generator will poll the values of the

input and compare data points each time this interval expires. This field

has a range of 0-214,748,364 seconds.

When this value is 0, the Alarm Generator will not poll the value of the

input and compare data points, and will only check for alarm conditons

when it receives event-driven updates to the data points.

You should note that other i.LON 100 applications may cause the Data

Server to poll this data point’s value as well. The poll rate specified by

these applications should be compatible with each other. For example, if an

Alarm Generator is polling a data point every 15 seconds, and the Data

Logger is polling that data point every 10 seconds, then the Data Server

will have to poll the value of the data point every five seconds to ensure

that each application gets a current value for each poll.

It is important to note this as you set poll rates for various applications, as

you may end up causing more polls than is efficient on your network. For

example, if an Alarm Generator is polling a data point every 9 seconds and

a Data Logger is polling a data point every 10 seconds, the Data Server

would have to poll the data point every second to ensure that each

application polls for a current value. This may create a significant amount

of undesired traffic.

Optional. Enter the description field of the UNVT_alarm2 data point

selected for the Alarm Generator. This data point can be selected by

defining the <Alarm2DataPoint> property. This description could include

the value that increased and caused the alarm, an alarm or error code

defined by the manufacturer, or the alarm limit. This can be a maximum of

22 characters long, and will be inserted in the description field of the

UNVT_alarm2 data point each time an alarm is generated.
