  • Socomec COUNTIS E24 (MID) three-phase direct 80 A energy meter with Modbus RTU over RS485.
  • The COUNTIS E23 (non-MID, ref. 4850 3050) shares the manual but has its own communication table, not checked here.
  • Addresses are the decimal addresses from Socomec's table, sent as-is. FC03 reads up to 128 words, FC06/FC16 write.
  • Values read 0xFFFF... when not available. The factory RS485 settings are not given in text form; check SETUP 2 on the display.
