  "notes": "Source: Accuenergy 'Acuvim 3 User Modbus Address Table' v1.00 (the vendor's spreadsheet at https://www.accuenergy.com/wp-content/uploads/Acuvim-3-User-Modbus-Address-Table-v1.00.xlsx ), sheets 'HS', 'Fundamental' and 'Energy'. Every row there is marked '03H Read', i.e. a holding register read. The map prints both the hex and the decimal form of each address, and they agree (0x2012 = 8210), so the addresses below are the wire addresses. Communication defaults are from the Acuvim 3 User Manual v1.0.13 (August 2026), section 7.2 'Network': Modbus TCP port 502 and Modbus TCP slave address 1, which is why this seed is modelled over TCP. The same manual states the RS-485 defaults for the RTU variant: slave address 1, baud rate 115200, no parity, 8 data bits, 1 stop bit (parity, data bits and stop bits are fixed and cannot be changed). Caveat: the vendor map gives the register type and width (Float = 2 registers, Double = 4 registers) but does not state a register word order, so the file keeps the default HighFirst. Deliberate omissions: the 10 s and high-speed timestamp/valid-flag/event-flag rows, the 'Meter Sys Config' and 'Meter IO Config' blocks (nominal values, transformer ratios, DI/DO behaviour), the demand and max/min groups, the TOU groups, the PQ event, alarm, IEEE 519 and EN 50160 report groups, and the per-phase energy rows for quadrants 2 to 4 (this seed carries the full quadrant-1 set plus the system totals of quadrants 2 to 4)."
