Sources and notes

  • Modbus Register Map LG64XX 'E' Series
    all five pages; the manual has no version or date

Source: Elmeasure, Modbus Register Map LG64XX 'E' Series

  • Registers are given as 4xxxx Modicon numbers; the address is the number minus 40000, with address base 1 (40101 is wire address 100).
  • The manual does not state the byte or word order. Floats are read big-endian; 'Long Inverse' values are read with the low word first, which is how the manual's name is understood.
  • The comment of each register says which of the two models the manual marks it for; registers marked for neither (diesel generator values, some optional ones) are listed as documented.
  • Reserved registers are left out.
