The RS485 port is a Modbus RTU slave with fixed register tables: status and alarm bits as coils (FC01), measurements and run counters as holding registers (FC03), and remote control as single-coil writes (FC05). This map covers the common status/alarm coils, the electrical and engine measurements, genset state codes, counters and the remote start/stop/mode/breaker commands.",

  "Coil addresses 0-6 are shared: FC01 reads return status bits, while an FC05 write of FF00 to the same address issues a remote command (start, stop, test, auto, manual, breaker). Each entry names both meanings; the write meaning is in capitals.",
  "HGM6110 (auto start) and HGM6120 (AMF) differ at command coils 5 and 6; HGM6100N and HGM6100CAN differ at several status coils (54, 62, 63, 70, 71, 79). Both meanings are given in the names.",
  "The FC05 table describes the command value as '00FFH', but the worked example frame sends FF 00 (high byte FF), which is also the standard Modbus ON value; use FF00.",
  "Left out: mains and gen frequency (0006, 0013). The table prints ratio 0.1 Hz, but NOTE 1 uses frequency with ratio 0.01 Hz as its worked example, so the scale is contradictory.",
  "Left out: the state delay registers (0035, 0037, 0039, 0041) and Load Output Percentage (0055), because no ratio is printed for them.",
  "Left out: the 32-bit current and power registers at 0206-0217 and 2500-2511. The document says value = high part x 65536 + low part but never says which address holds the high part, so the word order is not established. The 16-bit versions (0014-0016, 0026-0028) are included.",
  "Left out: ECU-only (HGM6100CAN) engine data 0032-0033 and 0056-0219 (J1939 values, DM1/DM2 fault codes, aftertreatment indicators) and the HGM6100N fuel-level logging block 0098-0114.",
  "A reading of 32766 means no valid data (the controller shows ###).",
  "Water temperature, oil pressure and fuel level are documented as unsigned, so negative coolant temperatures cannot be represented as documented.",
  "The ATS running status (0038) has no value table in the document; only the raw code is available."
