Eaton EM19 M Modbus Register Map

The Eaton EM19 M is a power meter used for power monitoring, energy metering, and facility automation. This page provides a sample Modbus register map with addresses, data types, and signal categories to help engineers commission, troubleshoot, and monitor the device. For Eaton EM19 M deployments, teams often use this map to surface demand, harmonics, and power factor data in critical power distribution and electrical monitoring systems.

This page shows a public register preview. Check the catalog in your installed XPF version for complete-map availability and licensing.

Confirm the exact model and firmware, address base, register function, word order, scaling and units against the manufacturer manual before polling. This preview does not establish hardware validation.
