Register map(s) for this device, with a note of how far each has been checked. Addresses are 0-based, as on the wire. Scale and byte order are confirmed only at the hardware-verified rung.
Round-trips through a real Modbus stack with no overlapping addresses and a word-order-sensitive codec — the map is internally coherent and wire-decodable. Does NOT prove byte-order or scaling match a real device: the emulator is seeded from the map's own types, so a uniformly wrong byte-order still round-trips. Only hardware-verified confirms byte-order/scale on the wire.

⚠ disputed: Power Consumption: 0.5 VA max. @ 5A per phase — disputed by Selec MFM384 official manuals which state that 0.5 VA @ 5A per phase is the CT input burden, whereas the actual auxiliary power consumption is less than 8VA (or less than 2VA for the 24V version) [1.2.7]
⚠ disputed: Operating temperature: 0 to +50°C, Humidity: 95% (non condensing) — disputed by Selec MFM384 official manuals which state operating temperature is -10°C to 55°C (or -5°C to 60°C) and humidity is up to 85% non-condensing
⚠ disputed: voltage_v12 @ 6 — disputed by Selec MFM384 official manuals which place Average Voltage LN at 30006 (0-based address 6) and Voltage V12 at 30008 (0-based address 8)
⚠ disputed: voltage_v23 @ 8 — disputed by Selec MFM384 official manuals which place Voltage V12 at 30008 (0-based address 8) and Voltage V23 at 30010 (0-based address 10)
⚠ disputed: voltage_v31 @ 10 — disputed by Selec MFM384 official manuals which place Voltage V23 at 30010 (0-based address 10) and Voltage V31 at 30012 (0-based address 12)

Each rung states what it proved and what it did not. Gray until proven; green is earned by hardware only.
