Secure CEWE CDM Modbus register map

  • Unofficial
  • 50 registers
  • Revision 2

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.
