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: Modbus Database (Jibril Sharafi, MIT licence), table entes/epr04; https://www.aggsoft.com/serial-data-logger/tutorials/modbus-data-logging/entes-epr04.htm. Not verified against the manufacturer's documentation

  • Entes EPR04.
  • Converted automatically from the Modbus Database (MIT licence, Jibril Sharafi).
  • Not verified against the manufacturer's documentation. The byte order is a guess: the source does not give one.
  • Corrections are welcome (CONTRIBUTING.md). Change x_status once this table has been checked against the manual.
  • Types, scaling and units corrected from the EPR-04S Modbus register table (32-bit values, ratios as in the table). This model has no manufacturer table of its own, so the map stays unofficial.
