 "summary": "The UMG 96RM-E is the Ethernet version of Janitza's UMG 96RM power analyser, with RS-485 as well. Measurements are big-endian 32-bit floats and the 19000-19120 'frequently required readings' block holds volts, amps, power, CosPhi, frequency, energy and THD. This map covers that block, total PF, the fourth current input, temperature inputs, digital output status and the main communication, transformer and reset parameters.",

  "Byte order: the list says its addresses return data big-endian (high byte first, high word in the lower register = ABCD). Adding 32768 to an address returns the same value little-endian; that mirror block is not listed.",
  "Access (R / RW) is copied from the list's RD/WR column. Digital output status rows (10080-10084) are marked read-only.",
  "Unlike the basic UMG 96RM list, 19068 is printed here as the L1-L3 consumed total (index [0]), so it is included.",
  "Transfer parameters conflict: p. 5 says 2 stop bits with no parity, while parameter 3 defaults to 0 = 1 stop bit, no parity. Default stop bits are left blank; check parameter 3.",
  "Left out: the SHORT and INT copies of measured values (fixed resolutions, and short values skip the CT/VT ratios), tariff energy, harmonics, min/max/mean blocks, comparators and the network rows at 25646-25719 (strings whose layout is not clear enough to decode).",
  "Left out: 508 (write to EEPROM) because the list does not say when it is needed.",
  "The address list covers registers and serial framing only; it does not name the Modbus TCP port, so the port is left blank here."
