How do I configure a Socomec E48 kWh meters for Modbus TCP communication with the Maxem Energy Controller?

Introduction

This article explains how to configure  Socomec E48 kWh meters for Modbus TCP communication with Maxem’s Energy Controller.

Preparation

A smooth installation requires proper preparation. Before configuring the Socomec E48  kWh meter, both the kWh meter and Maxem’s Energy Controller must be successfully installed to ensure proper communication between the meter and the controller.

Configuration steps

The meter is configured using the following onscreen configuration:

• Set the IP Address:

  • 192.168.25.10 → kWh meter measuring the main connection

  • 192.168.25.11 → next kWh meter

  • 192.168.25.12 → subsequent kWh meter

  • …and so on for additional meters

• Set the Subnet Mask: 255.255.255.0

• Set the Gateway: 192.168.25.1

• Save the Settings:

  1. Press the “↤” button for 3 seconds to enable saving.

  2. Press the “↤” button briefly and confirm by selecting “Y” (Yes).

• Default Settings Used by the Meter:

  • Unit ID: 5

  • Port Number: 502 (Modbus TCP)
