 "summary": "SmartGen's HGM9510N, HGM9520N and HGM9530N are genset paralleling controllers; the HGM9520N variant also commands a mains breaker. Two RS485 ports speak Modbus RTU and the RJ45 port speaks Modbus TCP, all with the same register tables. Status, alarms and measurements are holding registers read with FC03; remote keys are FC05 coil writes; the clock and two load-share setpoints are FC06 writes. This map covers status words, voltages, currents, powers, engine values, breaker and genset state codes, counters and the remote command coils.",

  "32-bit values put the low 16 bits at the lower address: the document's example reads A-phase active power at 0174-0175 as E240h, 0001h and combines them to 0001E240h (123456). That is CDAB word order; it is applied to every 4-byte value in the table.",
  "The alarm area 0001-0105 is seven 15-word fields (shutdown, trip-and-stop, trip, safety trip-and-stop, safety trip, block, warning). Each field uses the same bit layout from the alarm data table; only the first word of the shutdown and warning fields is mapped here. Bits of later words are in the document (pp. 36-41).",
  "Engine temperature (0220) has no signedness printed but its range starts at -50, so it is listed as signed 16-bit.",
  "Left out: ROCOF (0136), Negative/Zero phase angle (0202-0203) and Aux. sensor values (0226, 0228) because no scale or unit is printed; Unbalanced Current (0204) because it is marked both 0-65535 and signed; Multi-unit Total Reactive Power (0285) because its unit is printed as kvarh; expansion module (AIN24/AIN8) values, per-breaker A/B counters (0341-0352), J1939 DM1/DM2 fault lists and the ECU aftertreatment/indicator block 0533-0625.",
  "A reading of 32766 means no valid data.",
  "FC06 is only accepted at 0296-0302 (clock) and at the two load-share setpoints 4368 and 4370; all other registers are read-only.",
  "Generator status codes 14 and 15 are After Stop and Stop Failure in this document (the order is reversed compared with the HGM6100N document).",
  "Left out: the per-phase, average and mains power factors (0198-0201, 0259). They are 2-byte registers with ratio 0.001, but the printed range -100.000 to 100.000 does not fit a 16-bit value at that ratio, so the scale is contradictory.",
  "Left out: the delay values that follow each state code (0261, 0263, 0265, 0267, 0269); no unit or ratio is printed for them.",
  "The RS485 data-format list gives the communication address as 1-245, while the address-assignment table elsewhere in the document says 1-254."
