EM-SC/EM-FC	3-phase power meter (split-core or flexible-coil CTs), Modbus RTU. Base address 0x2000 (=8192 decimal). Common: vendor/product/firmware IDs, command, comms settings at 8192-8206. EM-specific: frequency at 8207 (mHz); phase currents at 8208-8211 (mA, u32); phase voltages at 8214-8218 (mV, u32); per-phase PF at 8222-8224 (×100); status at 8225; CT full-scale at 8226; cumulative energy at 8232 (mWh, s64) and reactive at 8239 (mVArh, s64). EM2 extended (fw≥4.0): 1-sec and 60-sec RMS averages, per-phase energy counters (µWh/µVArh, s64) at 8449-8549; last-cycle values and per-phase PF signs at 8536-8553.	Unofficial		87
