Eaton Power Xpert PXM 4000/6000/8000 meter

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.

cross-referenced (demoted: under-extracted stub (<=3 regs); needs re-extraction (#52))

Imported from a third-party source and NOT verified by us — not even structure-checked. An unverified claim, shown so you can find the device; trust it no more than the source it came from.

point	address (0-based)	type	scale	unit
subnet_timeout	2004	U16	1

link settings as documented (unverified): RTU/ASCII/TCP; baud 9600/19200/38400/57600/115200; Supports Modbus RTU Slave, Slave-Gateway, Master-Gateway, Slave (ASCII), or Master-IO. The RS485 CE3 port supports Modbus RTU slave to a master monitoring system.

⚠ VERIFY THAT ANY INCOMING AC POWER OR FOREIGN POWER SOURCES ARE TURNED OFF AND LOCKED OUT BEFORE PERFORMING ANY WORK ON THE POWER XPERT METER OR ASSOCIATED EQUIPMENT. — Starkest reads only; we never write a control register.

The trust ladder

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

generated — A prompt produced it. Unproven — anyone can regenerate this.
structure-verified — Decode path is structurally sound (addresses, widths, finite values). Does NOT prove word order or scaling.
coherence-checked — 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.
hardware-verified (software-key) x1 — Matched a real device with operator-attested readings as ground truth — the only rung that confirms word order + scaling on the wire.
