 "summary": "Schneider Electric's process/pump variable frequency drive family with Modbus RTU on an RJ45 port and a Modbus TCP server on the embedded Ethernet port. Both use the same decimal logical addresses, sent unchanged as holding-register addresses. This map covers the CiA402 command/status words (CMD/ETA), frequency and speed references, the main monitors (motor frequency, current, voltages, DC bus, thermal states, power), energy counters, fault/warning codes, I/O states and the Modbus, Ethernet and channel settings.",

The Modbus serial manual's read example asks for W3102-W3105 by sending starting address 0C1E hex (= 3102) and writes W9001 at 2329 hex. All drive data are holding registers. On Modbus TCP use unit ID 0 or 248 for the drive; unit ID 255 reaches the Ethernet I/O scanner instead."

  "LCR (3204) is left unscaled: the parameter file defers to the programming manual, which gives a 0.01 A step for drives up to 15 kW, 0.1 A from 18 to 160 kW and 1 A above.",
  "LFR (8502) and RFR (3202) are 0.1 Hz only while CMI bit 9 = 0 (power-up default); with bit 9 = 1 they become a signed value where 32767 = tFr.",

  "Left out: all 32-bit values (RTH/PTH run and power-on time 3244/3246, energy saved, fan time, today/yesterday kWh) because none of the documents states the word order; NCR and ITH (current step depends on rating); EPRW, OPRW, IPRW, ILN, AI physical values, PID reference/feedback and pump sensor values (unit 'refer to programming manual' or set by configurable system units).",
  "OC0-OC4 and IC0-IC4 are R/WS in the parameter file (writable only when stopped, e.g. to reset). Energy is split into 16-bit 0-999 registers per decade: total motor energy = OC4 TWh + OC3 GWh + OC2 MWh + OC1 kWh + OC0 Wh, input energy likewise with IC0-IC4.",
  "Registers marked RW that the source lists as R/WS can only be written while the drive is not running.",
  "LFT and DP0-DP3 use the full LFT list (135 codes) and LALR the full ALR list (112 codes) from the parameter file Enumerations sheet.",
  "Left out: IPR (3218, input power estimate) because the parameter file types it as signed 16-bit but gives an unsigned 0-65535 % range.",
  "None of the sources states the Modbus TCP port number, so tcp_port is left null (502 is the usual Modbus TCP port but is not confirmed here)."
