Table and standardization examples

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

Table examples

The patterns below reflect real sharing behavior.
  • nexalis_<org_name>_analog_Xminavg: standardized analog values at fixed period (e.g., 5-minute intervals), with normalization fields: assetType, logicalNode, dataObject, engUnits, multiplier and adder.
  • nexalis_<org_name>_discrete: discrete/event-oriented signals where value may be numeric code, boolean, or enum-like text.
avg_std row shape (analog): hf_std row shape (discrete):

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. Example: What each row means (using the model descriptions):
  1. Inverter line-to-line voltage (C–A) → INV.MMXU.PPV.phsCA
    Three Phase Measurements → Phase-to-Phase Voltage → Phase C-A, Analog in V.
  2. Inverter total active power → INV.MMXU.TotW
    Three Phase Measurements → Active Power (P), Analog in kW.
  3. Tracker setpoint position → TRKMOT.GAPC.PosReq
    Generic automatic process control → Motor setpoint position, Analog in °.
  4. Meter energy imported (from grid) → Meter.MMXU.DmdTotWh
    Three Phase Measurements → Energy absorbed from the grid, Analog in kWh.
  5. Plane-of-Array irradiance → MeteoSta.MMET.POAInsol
    Meteorological information → Plane of Array (POA) Irradiance, Analog in W/m2.
  6. HV breaker position at site → SITE.XCBR.Pos.HV
    Switching Circuit Breaker → Position status → High Voltage, Discrete (open/closed).
  7. String DC current (bifacial) → String.MMDC.Amp.Bifacial
    DC Electrical Measurements → DC Current → Bifacial, Analog in A.
  8. BESS effective state of charge (energy-based) → STO.DSTO.SocEffWhPct
    DER storage unit → Effective State of Charge based on available energy (Wh), Analog in %.
  9. BESS inverter AC charging power → STO_INV.MMXU.DmdW
    Three Phase Measurements → AC Charging Power, Analog in kW.
  10. Inverter active-power reference (percent) → INV.DINV.TotWRefPct
    DER Inverter Model → Active Power Reference setpoint in percentage, Analog in %.
