Sources and notes

  • Only the PM1200 communicates: the PM1000 has no RS-485 port.
  • Function 03 only. Registers are numbered as in the manual (3901 is holding register 43901), 1-based, so 3901 is sent as 3900.
  • Values are 32-bit floats, low word first ('little endian float' in the manual), in base units (V, A, W, VA, Wh); the run counters are 32-bit integers.
  • This map uses the individual parameter addresses (3861-3999), which can be read one value at a time. The manual's block addresses (3001-3199, 3721-3775) hold the same data but must be read as whole blocks of 20 registers (FAQ FA212915), so they are left out.
  • Factory settings: address 1, 9600 bps, even parity, 8 data bits, 1 stop bit. Poll about once a second at 9600 bps.
  • Written from the manufacturer's manual; not tested on a device.
