Enabling Connectivity for AC Power Monitoring

Introduction

A leading computer technology company operates multiple data centers across the U.S. To maintain stable operations, a system integrator developed an energy management system (EMS) to monitor AC power stability. This required reliable communication between power devices—such as low-voltage switchgears and automated transfer switches (ATS)—and the EMS, enabling operators to receive timely power data and make fast decisions to minimize downtime.

System Requirements

• Convert Modbus RTU to Modbus TCP seamlessly
• Gather both proprietary and digital input data
• Use one tool for configuring and maintaining all Moxa devices

Moxa Solution

Power devices within low-voltage switchgears and ATS—such as power relays, meters, and circuit breakers—needed reliable communication with the EMS. Moxa’s NPort 6450 secure terminal servers, MGate MB3170/MB3270 Modbus gateways, and ioLogik E1210 remote I/Os provided seamless connectivity across various interfaces and protocols. These devices also offer user-friendly configuration tools, Ethernet cascading to streamline network topology, and built-in Modbus troubleshooting features to help engineers quickly pinpoint communication issues.
