4.1.1 Retrieving Data Table from the FlexDAQ Hub Logger
Connect to the Hub logger using the
LoggerNet™ Connect application and click
'Collect Now' to retrieve the data.
Two data tables will be downloaded for each Node Logger type in the network. One
file will contain sensor data. The other will contain the logger and RSTAR network
diagnostic data.
4.1.2 RSTAR Sensor Data Table and Diagnostic Data Table
Each logger table will record the battery voltage and temperature of the Hub Logger
as the first two data fields of the table. Subsequent columns contain the sensor or
diagnostic data.

For example, the column heading 'DT11-2_Ch-1' in Figure 4-1 is the first channel of
the second data logger in the network. A reading of 'NAN' indicates that data was not
received at the RTU from the Node Logger.
Information about each transmission from each logger is stored within the diagnostic
data file. The definitions for each field type are defined in Table 4-1.
The data logger prefix in the field name (E.G., ‘DT11-2’) is shared between the
sensor data table and the diagnostic data table. This relationship is useful for
determining the origin of sensor data.
For example, to find the origin logger of the data reco
rded in the ‘DT11-2_Ch-1’
column, simply find the serial number recorded in the ‘DT11-2_SerianNumber’ field
of the diagnostic data table.
Node loggers will be in ascending serial number order in the sensor data and
diagnostic data tables if no modifications have been made to the RSTAR network.
