Belimo UK24MOD MP-to-Modbus gateway

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 9600/19200/38400/76800; FC 03,06; Baud rate, parity, and termination are adjustable via DIP switches. Parity can be NONE (2 stop bits) or EVEN (1 stop bit).

⚠ Due to safety considerations, the only override values permitted in the case of actuators for fire dampers are Open (1) and Fast_closed (6). The operating position (Open) must also be repeated within 120 seconds (recommendation: 90 sec.). — Starkest reads only; we never write a control register.

isolationThe GND of the RS485 line is galvanically isolated from the MP-Bus GND.
wiring notesAll terminals suitable for 2 x 1.5 mm2. Tool connector is RJ12.
response timeout2 ms
sentinel values65535 is entered for absolute/relative volumetric flow if the actuator type does not support it.
protocol notesThe response delay of the device is set to a fixed 4 ms with 9600 Bd. A delay of 2 ms is used as a default with higher baud rates. Adjustable via register 1003 (2...100 ms).

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.
