verified connector library

Endress+Hauser Promag W 10 flowmeter

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.

interop-verified

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.

link settings as documented (unverified): RTU; baud 1200/2400/4800/9600/19200/38400/57600/115200; FC 03,04,06,08,16,23; Response times: Direct data access: typically 25 to 50 ms, Auto-scan buffer: typically 3 to 5 ms.

⚠ Components carry voltage! Incorrect work performed on the electrical connections can result in an electric shock. — 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.

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.
