 "summary": "The PXM 1000 series are compact multifunction power and energy meters with a built-in RS-485 port running Modbus RTU (DNP3.0 selectable) and optional plug-in I/O and communication modules. Live readings are IEEE floats in holding registers from 4000H, energy counters are 32-bit integers, and setup values are 16-bit words from 0FFDH. This map covers the comm and CT settings, status, voltages, currents, powers, power factor, demand, energy, THD, phase angles and the first I/O module's inputs and relays.",

 "notes": [
  "IMPORTANT - primary vs secondary: the 4000H measurement block (voltages, currents, powers and power demand) holds real primary values only when Basic Parameter Mode (101DH) = 1. The manual's default is 0 = Secondary, where voltages must be multiplied by PT1/PT2, currents by CT1/CT2 and powers by both (use CT2 = 5 only for a 5 A CT secondary, otherwise 1). Every affected register says so; scale 1 and the units here assume Primary mode. Frequency, power factor and unbalance are not affected.",
  "Word order: the manual defines Dword as high word first, and its function-03 example returns frequency 4000H-4001H as 42 48 00 00 (50.00 Hz) with the high word in the first register. Its function-16 energy example writes 0A9D then 4089. All 32-bit values here are ABCD.",
  "Left out: current demand 4600H-4605H. Its table gives only the secondary formula with format code F1 and does not say whether Basic Parameter Mode (101DH) applies, so its scaling is ambiguous.",
  "Energy registers 4048H-4059H: scale 0.1 kWh / kvarh / kVAh applies to primary energy (format codes F4-F6), which is the default Energy Display Mode (1019H = 0). If 1019H is set to 1 (Secondary) the same registers hold secondary energy in 0.001 units (F7-F9). The manual prints the apparent energy unit as kVA; kVAh is used here.",
  "The system-parameter table prints address 0ffdH twice (Frequency and First Communication Protocol). The manual's notes and its sealed-parameter table both put the protocol at 0FFEH, so Frequency is kept at 0FFDH and the protocol at 0FFEH.",
  "Left out: PT1 (1005H, printed as a 32-bit 'Unit 32' with a one-decimal range but no stated scaling) and PT2 (1007H, a word with a one-decimal default of 220.0 but no stated scaling). The PT ratio still matters when Basic Parameter Mode is Secondary.",
  "Left out: password (1000H), the 100 ms refresh block 3000H (always secondary values, duplicates 4000H), the standard-register block 2000H (duplicates), the load-characteristic register 4040H (an ASCII code stored in a float), individual harmonics, max/min records with timestamps, sequence components, alarm, SOE and data-log blocks, per-phase energy (4620H-463DH), pulse counters and analog I/O.",
  "Digital inputs DI7-DI28 and relays 5-8 follow the same pattern on further I/O modules (see manual Tables 76-77); only the first modules' points are listed."
