Data Point References
The SmartServer has a more abstract and flexible method for referencing data points on the
SmartServer’s embedded applications by their parent functional blocks. Primarily, the data point type
is not specified by the tag name (for example, the SNVT_alarm_2 output tag is obsolete). In Version
4.0, each functional block representing a SmartServer embedded application has a collection of data
point references. The data point type is specified by the dpType attribute, and it is a reference to the
data point’s programmatic name as defined in the functional profile template. Some functional
blocks also extend the base data point reference XML type. In these cases, the <DataPoint> tag also
has an xsi:type attribute with the derived type.
The following code samples demonstrate how data points on the SmartServer’s embedded applications
are referenced. In the first example, the nvoAgAlarmFlag data point on an Alarm Generator functional
block is referenced. In the second example, the nvoDlLevAlarm data point on a Data Logger
functional block is referenced:
<DataPoint dpType="nvoAlarmFlag" discrim="dir_out">
<UCPTname>Net/LON/iLON App/Alarm Generator[0]/nvoAgAlarmFlag[0]</UCPTname>
<UCPTformatDescription>#0000000000000000[0].SNVT_switch</UCPTformatDescription>
</DataPoint>
