Table Examples

This page provides examples of the actual tables and values available when querying through the Delta Sharing API. It complements the Data Model page by showing concrete outputs for raw, standardized, averaged, and high-frequency data.

Raw Data

Raw data comes directly from the device source. dataPoint is unmodified from the communication protocol. Example:
siteNamedeviceModeldeviceIDsubDeviceIDdataPoint
IgnitionINV_8896INV_8896Inverter_tags/INV_8896/VPHSCA
IgnitionTRK_88103TRK_88103/NCU_2/37NexTracker_tags/TRK_88103/NCU_2/Setpoints/Tracker_Setpoint_37/…
IgnitionINV_11B131INV_11B131Inverter_tags/INV_11B131/TOTW

Standardized Data

Raw tags are mapped to the Nexalis Reference Data Model. This adds semantic fields such as assetType, logicalNode, dataObject, engUnits, and measurementType. Example:

Standardization — Ten practical examples Raw tags are mapped to the Nexalis Reference Data Model. This adds semantic fields such as assetType, logicalNode, dataObject, subDataObject, engUnits, and measurementType. How to read this: assetType = equipment class → logicalNode = tag group → dataObject (+ optional subDataObject) = the specific signal → measurementType = Analog/Discrete → engUnits = engineering units.

Average Data (gold_<user>_avg_std)

For analog values, averages are computed over a fixed time interval (e.g., 5 minutes), configurable at the Nexalis Agent level. Example:

High Frequency Data (gold_<user>_hf_std)

High-frequency (second-level) data is collected in near real time and includes discrete/boolean signals. Example:
