Eastron Modbus register maps
4 devices with the register list read from the manufacturer's own manual, plus downloads for Modbus Poll.
From the manufacturer manual
- Energy meters SDM120-Modbus Single phase DIN rail energy meter with an RS485 Modbus RTU port. It reports voltage, current, power, power factor, frequency, import and export energy and power demand.
- Energy meters SDM230-Modbus Single phase two-module DIN rail energy meter with an RS485 Modbus RTU port. It reports voltage, current, active, apparent and reactive power, power factor, frequency, import and export energy and demand values.
- Energy meters SDM630-Modbus V2 DIN rail three phase energy meter for 3P4W, 3P3W and 1P2W systems with an RS485 Modbus RTU port. It reports voltage, current, power, power factor, frequency, harmonic distortion and import and export energy counters.
- Energy meters SDM72D-M DIN rail three phase four wire energy meter with an RS485 Modbus RTU port, pulse output and resettable energy counters. This map follows the SDM72D-M-2 Modbus protocol section, which lists voltage, current, power, power factor, frequency, import, export and resettable energy as 32-bit floats. The older SDM72D-M and SDM72D-M-1 manuals list only a subset of these registers.
