98 Modbus registers of the Schneider Electric iEM3000, with the address on the wire, the 30001-style reference, data type, byte order, unit and scale. Transcribed from iEM3000 series user manual, Communications via Modbus (iEM3000 modbus register).

Acti9 iEM3000 DIN-rail energy meters with Modbus RTU (iEM3150 to iEM3555); measurements are 32-bit floats, energies also as 64-bit integers.

Connection notes

  • Every register here is a holding register (function code 3).
  • Addresses are the manual's register numbers minus one, the convention of the other PowerLogic maps here (the numbers match the PM5000 lists, e.g. Current I1 = 3000). The manual calls its numbers the address in the frame; if every read is off by one register, use the manual's number.
  • Word order is not stated in the manual; ABCD as for the PM5000 lists.
  • Settings marked in the notes are changed with setup commands written to register 5250 (function 16); the command interface registers are left out.
  • The per-phase reactive energy registers 45128-45132 of the manual's 1PH4W addendum are left out because their unit (kVARh) contradicts the other float energies (VARh).

Read it by name

Read the iEM3000 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.

This device speaks Modbus RTU: reach it through a Modbus TCP gateway and use the gateway’s address with the device’s unit ID.

Ask your assistant

Read total_active_energy_import, total_active_energy_export, total_reactive_energy_import from iem3000-1.

The tool call it makes

read_named(device: "iem3000-1", keys: ["total_active_energy_import", "total_active_energy_export", "total_reactive_energy_import"])

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.
