Register map(s) for this device, each at the trust rung it earned. Addresses are 0-based as on the wire. Word order and scaling are confirmed at the hardware-verified rung and at no rung below it.
Read + decoded cleanly over a real network vs an independent third-party Modbus test server (transport and framing; reads are remapped into the server's register window, so the map's own addresses are NOT exercised). Does NOT prove word order/scaling against the actual device.

⚠ disputed: inter_frame_delay_ms: 3 — disputed by WattNode Modbus Installation and Operation Manual (Rev 1.18c) which states that the inter-frame silent interval is baud-rate dependent (3.6 ms at 9600 baud, ~2 ms at 19200 baud) rather than a fixed 3 ms.
Each rung states what it proved and what it did not. Gray until proven; green is earned by hardware only.
If your device isn't here, upload its register map. Generation is free, and the connector keeps the rung it earns under testing.
To prove a connector against your own device, order hardware verification. If it doesn't verify, you don't pay.
Platform builders can license the verified library: machine-readable maps, the firmware matrix, API access.
