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.
| point | address (0-based) | type | scale | unit |
|---|---|---|---|---|
| serial_number | 0 | F32BE | 1 | |
| energy_index | 2 | F32BE | 1 | kWh |
| volume | 4 | F32BE | 1 | Litre |
| instantaneous_power | 6 | F32BE | 0.1 | 1/10e kW |
| instantaneous_flowrate | 8 | F32BE | 1 | Litre/h |
| outgoing_temperature | 10 | F32BE | 0.1 | °C /10 |
| return_temperature | 12 | F32BE | 0.1 | °C /10 |
| temperature_difference | 14 | F32BE | 0.01 | °K/100 |
| air_conditioning_energy_index | 16 | F32BE | 1 | kWh |
| terminals | A = D+, B = D- |
| A/B polarity | protected against polarity reversals |
| termination | 120 Ohm with switch |
| connector | terminal block |
| isolation | Double isolation |
| wiring notes | 2 wires, Differential Half-Duplex |
| max registers/read | 22 |
| sentinel values | Alarm data on the meter are returned in format 999999 (decimal). Optional data are returned with a value of 000000 (decimal) when not available. Negative values are transmitted in absolute values. |
| protocol notes | The Modbus data returned are updated with the meter data every minute. Communication priority is given to the optical connector, in which case Modbus data remain on the latest meter values read prior to optical communication. |
| serial register | 0000 |
| power | 3.6 V - 12 V DC, Current < 35 mA (120 mA in Modbus communication) |
| environment | Storage temperature: -10 °C ... +60 °C, Operating temperature: +5 °C ... +55 °C, Relative humidity: < 95 % |
| certifications | EN 60950, EN 61000-6.2, EN 61000-6.3 |

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.
