ECM — Energy Consumption Management
Energy Consumption Management — energy KPIs, load profiles, demand charges. One enum, five structured types, pulls DI and IA.
OPC UA companion specification for energy-management interfaces on industrial equipment — current consumption, demand profiles, KPI rollups, peak management.

Notable types
The five DTOs carry energy measurements and rollups:
EnergyKpiData— KPI snapshot (period, totalised value, unit)EnergyDemandData— peak/average demand recordEnergyMeasurementData— instantaneous measurement (V, A, P, Q)EnergyTimePeriodData— time-window descriptorEnergyConsumptionData— cumulative consumption
The single enum classifies the measurement direction (consumption vs production / import vs export).
