Example 2: Using Case Logic for Log transfer

You can use the SmartServer’s built-in Type Translator application to update the source data point in
the Web connection used for the log transfer. In this example, case logic is used to update the source
data point and send the data log file when the data logger becomes full. To do this, you do the
following:

1. Identify a data point in the SmartServer tree to be used as the trigger for the log transfer. This

example adds a SNVT_switch dynamic data point to the SmartServer i.LON App device’s Virtual
Functional Block (Net/LON/iLON App/VirtFB/nvClearLog).

2. Create a Web connection for data logger extraction, configure a data logger, and attach a data log

file as described in the previous sections.

3. Create a Type Translator. See Chapter 11, Using Type Translators, for more information.

4. Add your specified trigger source data point and the nviDlClear and nvoDlLevAlarm data points

on the specified data logger to the Type Translator.
