Schneider Electric iEM3000
Three phase DIN rail energy meter for power, energy per phase and energy per tariff.
The Schneider Electric iEM3000 is a DIN rail energy meter series that measures current, voltage, power and energy in single and three phase installations, directly up to 125 A or with current transformers. This Modbus RTU template reads all measurements and energy counters per phase and per tariff, and lets you send tariff, reset and setup commands from ModbusCloud.

Send your device list
If a device is not in the library yet, we build the template for free as soon as we have the register data.
Use cases
- Follow consumption per group or tenant on a dashboard with power and energy per phase.
- Get an alert when total active power passes a threshold you set for the board.
- Keep a year of energy history to compare months and spot unusual base load.
- Split consumption into day and night tariffs with the energy per tariff counters.
- Watch the diagnostics status and get an alert when the meter reports a wiring or frequency error.
Installation
Connect the RS485 terminals of the meter to the RS485 port of the ModbusCloud Gateway, with termination at both ends of the bus.
On the meter display, set the Modbus address, speed and parity in the Communication menu.
In ModbusCloud, add a Modbus device with the same address and serial settings and import this template.
Check that voltage and frequency come in with plausible values, then compare the total energy with the display.
Things to watch for
The meter does not answer. What should I check?
Check that the address, speed and parity in ModbusCloud match the Communication menu of the meter; the meter always uses 1 stop bit. Swap the two RS485 wires if nothing answers, and make sure the bus is terminated at both ends. Only the models ending in 50 or 55 have Modbus; a 10, 15 or 35 model has no RS485.
Why do reactive power and export energy stay empty?
Reactive and apparent power, export and reactive energy, tariffs and input metering exist only on the iEM3155, iEM3255 and iEM3355. On the iEM3150, iEM3250 and iEM3350 these registers give no valid value. Hide them in the device view if you use one of those models.
Should I use the Wh or the kWh energy values?
Both show the same counter. The Wh values are exact integer counters and suit long term history; the kWh values are easier to read on a dashboard. Pick one per counter so you do not log the same energy twice.
How do I write a setting such as the active tariff?
The meter accepts settings only as commands. Write the command number to Requested Command together with its parameters in one write, for example 2008 for Set Tariff, then read Command Result: 0 means accepted, 3000 to 3007 mean rejected. Setting the tariff this way works only when the tariff mode is set to communication.
Several meters share one RS485 line. How do I set that up?
Give every meter its own address and the same speed and parity, wire them as a line from meter to meter and terminate both ends. In ModbusCloud you add each meter as its own Modbus device with this template.
