Column Names
Column names are described without spaces in order to improve readability in a basic text editor to avoid
confusion with the tab column separators. The following describes how a column name is generated in an
export:
Measurements Export:
Ch{Channel Number}_{Channel Mode}_{Height}_{Bearing Name}_{Column Type}_{Units}
Diagnostic Export:
{Diagnostic Type}_{Column Type}_{Units}
Export Rules
The exports must be able to present data from multiple datapoint types for a given channel as that channel may
change in its configuration over time. Also, channels may be disabled and enabled independently across time.
The following rules govern how the exports handle these cases:
The columns generated for a channel represent the superset of all column types reported by that channel over
the history covered by the given export. For example, if digital channel 3 changed from anemometer to totalizer,
then channel 3 would have the following columns: Avg, Min, Max, SD, Gust, & Total. The data for the first five
columns would be mutually exclusive in the export as the channel may not report both types at the same time.
Columns that do not have any data in them are not exported. If channels 7-12 are disabled, then the export does
not have any columns representing those channels (there are no blank “(tab)(tab)” columns).
Rows that do not have any data in them are not exported. If there is no data for a time that would otherwise
typically have data (10 minute boundary, for example), there is no row generated for that time.
These rules allow the export file to work in a manner that is similar to how the underlying datastream is
structured. This is desirable because it allows future datapoints to be created without the repercussions of
fitting the fields into a more rigidly structured export format. Also, it reduces file size which is important when
considering exports of sample data.
Export Header Format
The beginning of the header information is identical across all export types. This is referenced in the proceeding
export formats as
{Export Header}
and is defined as follows:
NRG Systems SymphoniePRO Desktop Application
Software Version:(tab){Software Version}
Export version:(tab)1
Generated:(tab){Export Generation Timestamp}
