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 only confirmed at the hardware-verified rung.
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.

Each rung states what it proved and what it did not. Gray until proven; green is earned by hardware only.
Have a device that isn't here? Upload its register map — generation is free, and the connector earns its rung by being proven, not claimed.
Need it proven on your own device? Hardware verification — if it doesn't verify, you don't pay.
Building a platform? License the verified library — machine-readable maps, firmware matrix, API access.
