Unofficial: Copied from an unofficial source and not tested. Read it as a draft and check a value on the real device before you rely on the rest. Check the map against the manufacturer's documentation before you write to a live device. Tested it? Report a test.

Sources and notes

Source: VARkombi-18-PC REGISTER TABLE (0x0400), as transcribed in the ModbusHub registry (MIT licence)

  • Measurements are sent as integers that must be multiplied by the transformer ratios read from the device (CTRF at 4096, VTRFwM at 4095); the descriptions give the formula when the manufacturer table prints it.
  • Converted from the ModbusHub transcription of the manufacturer table. Not verified on a device.
  • The manufacturer table has no unit column: units are taken from the register names.
