ABB M4M 20/M4M 30 Modbus register map

Also searched as: ABB M4M 20 · ABB M4M 30 · M4M 20 Modbus · M4M 30 Modbus · M4M 20 Ethernet · M4M 30 Ethernet · M4M 20 I/O · M4M 30 I/O

228 Modbus registers of the ABB M4M 20 and M4M 30, with the address on the wire, the 30001-style reference, data type, byte order, unit and scale. Transcribed from Modbus protocol map for M4M network analyzers (Revision F (map v1.3O)).

ABB M4M 20 and M4M 30 network analyzers with Modbus RTU or Modbus TCP; integers with fixed resolution, the same layout as ABB's EQ meters.

Connection notes

  • Addresses are the hex register numbers from ABB's map, sent unchanged (the manual's example frame reads phase voltage L1 at 0x5B02).
  • Every register here is a holding register (function code 3); writes use function code 6 or 16.
  • Multi-register values put the most significant byte in the first register.
  • Missing quantities read as invalid, FFFF for unsigned and 7FFF... for signed values.
  • The readable range is 0x1000-0x8EFF. Modbus TCP uses port 502 by default.
  • The M4M 32 and the Rogowski and -M versions are left out; check the workbook's product columns for them.

Read it by name

Read the M4M 20/M4M 30 with an AI assistant

The Proxus Industrial MCP Server includes this map. Set it on the device, and Claude, Cursor or VS Code reads registers by key with the right type, byte order, scale and unit. It only reads.

  "devices": {
    "m4m-1": {
      "protocol": "modbus-tcp",
      "host": "192.168.10.40",
      "unit_id": 1,
      "map": "abb/m4m-20-m4m-30"

  }
}

Ask your assistant

Read voltage_system, voltage_l1_n, voltage_l2_n from m4m-1.

The tool call it makes

read_named(device: "m4m-1", keys: ["voltage_system", "voltage_l1_n", "voltage_l2_n"])

Have this device? Verify the map.

Ask your assistant to run verify_device_map. It reads every register once, read-only, checks that the values are plausible and asks you to compare two values with the display. You get a report and a prefilled GitHub issue to submit; your name goes on this map’s verified list.

How verification works

Collecting from many devices?

Proxus reads Modbus TCP and RTU devices next to the machines, keeps the history and delivers the values to dashboards, databases and AI.
