 "summary": "The Acuvim-L is a panel-mount multifunction power and energy meter with RS485 Modbus RTU and optional expansion modules (Ethernet with Modbus TCP, I/O). All register data is in holding registers at hex addresses: settings and status as 16-bit words, real-time readings as 32-bit floats from 2180H, energy as scaled 32-bit integers from 2080H and THD as scaled 16-bit values. Relays and digital inputs on I/O modules use coil and discrete-input functions.",

 "notes": [
  "Word order: the read example returns frequency 50.00 Hz as 42 48 00 00 (high word first) and dword values are defined as high word first. All 32-bit values here are ABCD.",
  "IMPORTANT - primary vs secondary: Basic Parameter Mode (101DH) controls the real-time float block (Table 6-19, 2180H-21D3H). Its default is 0 = Secondary. Only with 101DH = 1 do the registers hold primary values, and only then are the scales and units in this map correct for voltage, current, power and demand. In secondary mode the manual gives primary voltage = value x PT1/PT2, current = value x CT1/CT2, power = value x (PT1/PT2) x (CT1/CT2) / 1000 (kW, kvar, kVA). For 333 mV and Rogowski (100 mV/50 Hz, 120 mV/60 Hz) CT options the manual says to use CT2 = 1 in that calculation, so the raw current value is then not a secondary-side ampere reading. This map cannot express a ratio taken from other registers, and PT1/PT2 are not mapped (see below), so set 101DH = 1 before using these registers. Frequency, power factor, unbalance and load type are the same in both modes.",
  "Power, reactive power, apparent power and power demand floats are divided by 1000 to give kW, kvar and kVA (primary mode), so scale 0.001 is used with those units.",
  "Energy scale depends on Energy Display Mode (1019H). The manual states the default is 'Primary 0.1 Mode' (register value 0, 'Primary in kWh'), for which the energy table gives Rx/10; scale 0.1 in this map is valid only in that mode and each energy register says so. Secondary mode (1) is Rx/1000. Mode 2 is labelled 'Primary in 0.01kWh' in the settings table but 'Primary 0.001 Mode' (Rx/1000) in the energy table, so its resolution is unclear.",
  "The manual's worked examples read the 4000H block (frequency at 4000H, energy at 4048H), but the v4 address tables list real-time floats at 3000H and 2180H and energy at 2080H. This map uses the tabulated 2180H/2080H addresses.",
  "Left out: net active/reactive/apparent energy (2086H, 2096H, 20A6H), typed uint32 but with a signed range; reactive and apparent power demand (21C8H/21CAH), whose formulas and units are swapped in the table.",
  "Left out: channel 1/2 baud rate (1002H, 102FH) and PT1/PT2 (1005H-1007H), whose encodings in a 16-bit word are not explained.",
  "Not covered: 3000H basic block (duplicates 2180H), harmonics by order, max/min, TOU, alarms, logs and I/O module settings.",
  "The channel 1 protocol register (0FFEH) lists 2 = BACnet MS/TP in the table, but the note under the table says 1 selects BACnet, so only 0 = Modbus is given.",
  "The energy table prints apparent-energy units as kVA; they are given here as kVAh.",
  "The address-block discrepancy above has not been checked on a meter: the worked examples and the historical-log section use 4000H (frequency) and 4002H (phase A voltage), while the register tables give 2180H/2080H. If 2180H returns an exception on older firmware, compare with the Acuvim II map."
