PM5000 Modbus Guide

Read voltage, current, power, power factor, frequency and energy from a Schneider PowerLogic PM5000-series power meter over Modbus RTU or TCP. This guide covers the register map, FLOAT32 decoding, serial settings and how to get live data — and log it — with ModbusManager on Windows.

// about the PM5000 series

One register map, many meters

The PowerLogic and EasyLogic PM5000 family shares a common Modbus measurement map, so the same addresses work across most models.

Schneider Electric’s PowerLogic PM5000 series (PM5110, PM5310, PM5330, PM5340, PM5560 and the PM55xx/56xx/57xx ranges) are panel-mounted power and energy meters used in switchboards, sub-metering and energy-management installations. They expose their measurements over Modbus RTU on RS-485 and, on Ethernet models, over Modbus TCP. The core metering registers — current, voltage, power, power factor, frequency and energy — sit at the same addresses across the family, so once you can read one PM5000 you can read most of them.

Modbus settings

Set these on the meter display (Communications / Setup menu), then match them in ModbusManager.

Setting	Typical value
Protocol (RS-485 models)	Modbus RTU
Baud rate	19200 (also 9600 / 38400)
Parity	Even (1 stop bit)
Data bits	8
Slave address	1–247 (set on meter)
Protocol (Ethernet models)	Modbus TCP, port 502
Function code (read)	03 — holding registers
Data type	FLOAT32 (2 registers, big-endian)

PM5000 measurement registers

All values below are FLOAT32 (two 16-bit registers each), read with function code 03. Addresses use Schneider’s 1-based documentation numbering.

Register	Measurement	Unit	Type
3000	Current A	A	FLOAT32
3002	Current B	A	FLOAT32
3004	Current C	A	FLOAT32
3010	Current Average	A	FLOAT32
3020	Voltage A-B	V	FLOAT32
3022	Voltage B-C	V	FLOAT32
3024	Voltage C-A	V	FLOAT32
3026	Voltage L-L Average	V	FLOAT32
3028	Voltage A-N	V	FLOAT32
3030	Voltage B-N	V	FLOAT32
3032	Voltage C-N	V	FLOAT32
3054	Active Power A	kW	FLOAT32
3056	Active Power B	kW	FLOAT32
3058	Active Power C	kW	FLOAT32
3060	Active Power Total	kW	FLOAT32
3068	Reactive Power Total	kVAR	FLOAT32
3076	Apparent Power Total	kVA	FLOAT32
3084	Power Factor Total	—	FLOAT32
3110	Frequency	Hz	FLOAT32

    Tip: to read all instantaneous values in one request, poll holding registers from 3000 for a block of ~112 registers (FC03), then map each pair above.
  

Energy registers (active/reactive/apparent energy, INT64 accumulators) live higher in the map and vary slightly by model — check the Modbus register list for your exact PM5000 model from Schneider Electric for those.

// how to read it

Read a PM5000 in three steps

From wiring to live values in a few minutes.

Step 1

Connect

Wire RS-485 A/B (and ground) to the meter’s comm terminals, or connect over Ethernet for TCP models. In ModbusManager pick RTU (19200, even, 1 stop) or TCP (port 502) and set the meter’s slave address.

Step 2

Poll & decode

Add a poll on holding registers (FC03) starting at 3000. Set the display type to FLOAT32 so each register pair is combined into a real value — otherwise voltages and powers look like nonsense.

Step 3

Visualise & log

Map the values to a dashboard for a live panel, log them to the Historian for energy studies, or set alarms on over-voltage or over-current.

// why modbusmanager

A practical tool for power meters

ModbusManager reads any PM5000 register directly, with built-in 16/32-bit and FLOAT32 decoding so you do not have to combine register pairs by hand. The Standard edition ($49) covers polling, scaling and the serial monitor. The Pro edition ($119) adds a drag-and-drop dashboard, a data logging Historian with CSV export for energy and load profiling, and an alarm system for limit monitoring — all running locally on Windows, with no SCADA server or cloud account.

PM5000 Modbus — FAQ

What Modbus settings does a PowerLogic PM5000 use?+

The PM5000 series communicates over Modbus RTU on RS-485 (typically 19200 baud, even parity, 1 stop bit) or Modbus TCP on port 502 on Ethernet models. The slave address and baud rate are set on the meter display.

Why does the PM5000 power value look wrong?+

PM5000 measurements are 32-bit floating point (FLOAT32) spanning two registers. If you read a register as a single 16-bit integer you get a meaningless number. Select a FLOAT32 / 32-bit float display so the register pair is combined correctly.

Are PM5000 registers holding or input registers?+

The PowerLogic measurement registers are read with Modbus function code 03 (holding registers). Note the 1-based documentation: register 3000 in the manual is address 2999 on the wire, though many tools handle this offset for you.

Which PM5000 models does this apply to?+

The base measurement map (current, voltage, power, energy) is shared across the PM5100, PM5300, PM5500, PM5600 and PM5700 families. Always confirm against the Modbus register list for your exact model from Schneider Electric, as higher-end models add registers.

Can I log PM5000 energy and power to a file?+

Yes. With ModbusManager Pro you can log any PM5000 register to a local Historian, view it as a trend chart and export to CSV. This is useful for energy studies and load profiling without a SCADA system.
