• All registers are holding registers (FC03 read, FC06/FC10 write). Addresses here are the zero-based hex addresses of the manual; the manual's decimal register numbers are one higher (e.g. 0x03E7 = register 1000).
• 32-bit values and floats span two registers with the high-order half first.
• Factory settings in normal mode are 57600 baud, address 1, Modbus RTU, 8 bits, no parity. For the first 5 minutes after power-up the RS-485 port also answers at 9600 baud, address 1.
• Energy registers are integers whose scale, digit count and decimal places follow the power and energy format setting (register 0x7535). Reset the energy after changing that format.
• Per-phase power and power factor are non-zero only with a wye hookup. Unlisted registers read 0.
• Not in this map: the integer readings block (0x0116-0x0130), uncompensated readings, minimum/maximum blocks and timestamps, harmonic and waveform registers, option card blocks, programmable settings, secondary readings and log retrieval.
