    "Function 03 and 04 both read the measurements. 32- and 64-bit values are sent high word first.",
    "The model is reported by function 17 (Report Slave ID): type code 0x79.",
    "Max (HI), min (LO), average and max demand values, harmonics, I/O and setup parameters (tables 4-8 of the manual) are not listed here.",
    "Tested on a DMG210 read over a Modbus TCP gateway, November 2026: all 65 registers read without errors. Checked: voltages, currents, power, power factor, THD, neutral current, asymmetry, the 32-bit and 64-bit energy counters (same values), hour meters, phase sequence and the word order (big). Frequency read 5003, so its scale is 0.01 (50.03 Hz), not 0.001 as this map had before."
