Janitza UMG103 Modbus Register Map

The Janitza UMG103 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 Janitza UMG103 deployments, teams often use this map to surface harmonics, energy, and power data in facility metering, commissioning, and operational analytics.

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.
