Suppose you want to read the total energy consumption data from the DMG 610 using a Modbus master device. You would send a Modbus read command to access the register 40001, which stores the total energy consumption data.
The DMG 610 uses . Most real-time values are stored as 32-bit floating-point numbers (IEEE 754) or 32-bit integers, requiring two consecutive 16-bit registers. Real-Time Voltage & Current Address (Hex) Address (Dec) Voltage L1-N Voltage L2-N Voltage L3-N Voltage L1-L2 Current L1 Current L2 Current L3 Power and Frequency Address (Hex) Address (Dec) Total Active Power Total Reactive Power Total Apparent Power Power Factor (Total) 🔋 Energy Counter Registers lovato dmg 610 modbus registers
| | Solution | |----------------------------------------|------------------------------------------------------------------------------| | Wrong scaling (e.g., 2300 V instead of 230.0 V) | Always apply /10 for voltage, /1000 for current and power. | | Garbage float values | Check byte order – DMG 610 uses AB CD (big-endian). Swap if needed. | | Cannot write to config registers | Write 1 to Reg 4999 first (unlock), then write config, then Reg 4999 = 0 . | | Communication timeout | Verify serial settings match device (often 19200, 8E1 for DMG 610). | Suppose you want to read the total energy
Here are some common Modbus registers used in the Lovato DMG 610: Most real-time values are stored as 32-bit floating-point
