Lovato DMG700 power meter

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.

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.

⚠ disputed: total_imported_active_energy @ 6688 — disputed by Lovato Modbus Protocol document I317 I GB 02_22 which lists Total Imported Active Energy at address 1A20H (6688 in decimal) but the actual register address is 1A20H (6688 decimal) while the document lists 6944 decimal in some third-party software maps. However, 1A20H is exactly 6688 decimal, so the address is correct but the other energy registers are offset: total_exported_active_energy is at 1A22H (6690 decimal), total_imported_reactive_energy is at 1A24H (6692 decimal), total_exported_reactive_energy is at 1A26H (6694 decimal), and total_apparent_energy is at 1A28H (6696 decimal).

The trust ladder

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.
