MasterPact NT/NW and PowerPact P- and R-frame - Modbus communication guide

This document provides technical information for users, installers, and maintenance personnel to operate the Modbus protocol on PowerPact P-frame and R-frame circuit breakers (250-3000 A) and MasterPact NT and NW circuit breakers (250-6000 A). It covers communication architecture using IFM Modbus-SL interface and IFE Ethernet interface, including detailed descriptions of Modbus registers, commands, datasets, protection parameters, measurement parameters, and file mechanisms. The guide explains real-time measurements, energy measurements, demand measurements, trip history, alarm management, and remote control capabilities. It includes information on BCM ULP module, IO module, MicroLogic trip units (types A, E, P, and H), and communication interfaces. The document details standard and legacy datasets, analog predefined alarms, basic and advanced protection parameters, and time-stamped information for effective circuit breaker management and monitoring.
