 "summary": "The DMG7000-DMG9000 are Lovato's 96x96 panel power analyzers. They answer Modbus RTU, ASCII or TCP depending on the communication port used, and EXS4 Easy Branch current modules on the same channel appear as extra Modbus nodes. Measurements are fixed-point 32-bit integers sent high word first. This map covers voltages, currents, powers, power factor, frequency, unbalance, THD, max demand, hour counter, I/O status, the real-time clock and the reset, tariff and remote-variable commands.",

So subtract 1: L1 voltage, printed 0x0002, is requested at address 0x0001. The same rule is applied to every register here."

  "Byte and word order are big endian (high word first), so every 2-register value is ABCD.",
  "Measurement registers are read with function 03 or 04 (same data); they are listed as input registers. At most 120 registers per request; Modbus TCP accepts one connection per physical port.",
  "Scale is the divisor printed in the Unit column: V/100 = 0.01 V, A/10000 = 0.0001 A, kW/100000 = 0.00001 kW (0.01 W), Hz/1000, PF /10000, %/100.",
  "Several power rows carry a '(1)' marker in the Unit column, but no footnote text for it appears in the English/Polish, English/Chinese or English/Russian editions. The printed scale is used here; confirm power readings against the front display at commissioning.",
  "Left out: all energy counters (0x1B20-0x1CFC). The table gives them 4 registers each but labels the format 'Unsigned Long' / 'Signed Long', which normally means 32 bits, so the bit width cannot be decoded with certainty.",
  "Left out: alarm, PLC, limit and remote-variable status blocks (0x2120-0x2140, 0x4F00 read), which are 40-bit fields across 3 registers without a stated word arrangement; min/max/average copies, harmonic spectra, angles, crest and k-factors, analogue inputs, counters and the DMG9000 power-quality statistics.",
  "Left out: parameter setup through menu/submenu/parameter selector registers (0x5000-0x5004); the example frames use addresses one lower than the table, as noted under addressing.",
  "Function 0x11 (report slave ID) returns a model code: 0x70 DMG7000, 0x75 DMG7500, 0x80 DMG8000, 0x90 DMG9000, 0x40 EXS4.",
  "EXS4 Easy Branch measuring points answer on their own node numbers (by default the DMG is node 1 and branch points take 2, 3, ...), with the subset of registers the manual marks as available for EXS4.",
  "Verifier: all seven example frames in the parameter-setup section carry valid CRCs, so the minus-one rule is taken from genuine frames (0x5000->4FFF, 0x5001->5000, 0x5002->5001, 0x5004->5003, 0x2F03->2F02).",
  "Verifier: the energy-counter width is not settled anywhere in the document - no 64-bit statement and no example frame for the 4-register rows, and total export energy is even typed 'Signed Long' - so they stay out."
