About the Book

Document Scope

ToDo: TBC @ experts, if Modbus communication is compatible with ComPacT NS switch-disconnectors.

The aim of this document is to provide users, installers, and maintenance personnel with the technical information needed to operate the Modbus protocol on the ComPacT™ NS circuit breakers and switch-disconnectors from 630 to 3200 A.

Validity Note

This document is valid for ComPacT NS circuit breakers with a BCM ULP circuit breaker communication module embedded, and connected:

  • either to an RS 485 serial line Modbus network using an IFM Modbus-SL interface for one circuit breaker,

  • or to an Ethernet network using an IFE Ethernet interface for one circuit breaker or an IFE Ethernet switchboard server.

This document describes the registers and commands available for the IMU modules with the following firmware version

IMU module

Part number

Firmware version

MicroLogic A trip unit

≥ V01.029

MicroLogic E trip unit

≥ V1.016

MicroLogic P trip unit

≥ 2014AQ or 8.284

BCM ULP module

≥ V4.1.9

IO module

LV434063

≥ V003.004.005

IFM interface

LV434000

≥ V003.001.012

IFE Ethernet interface

LV434001

≥ V004.007.000

LV434010

IFE Server

LV434002

≥ V003.016.000

LV434011

You can update the firmware of the IMU modules by using the latest version of EcoStruxure Power Commission software.

Refer to MasterPact Modbus Legacy User Guide Related Documents for communication architectures using:

  • the Modbus legacy port of the BCM ULP module

  • the IFM interface with the Modbus legacy firmware

NOTE: All BCM breaker communication module are BCM ULP module since week 45 of 2010.
