  "notes": "Addresses are the \"Offset\" values in the SENTRON PAC3200 product manual (A5E01168664, chapter 3.9) and are used as wire addresses; address 0 is not used by the measured values. The manual states that all measured values can be read with function code 03 and with function code 04, so the entries below work as holding registers and, on the same addresses, as input registers. Measured values are IEEE 754 single precision (2 registers), the energy counters are IEEE 754 double precision (4 registers, Wh/varh/VAh). Energy counters and settings are writable; writing an energy counter resets or preloads it. Status bits, limit states and the digital input/output are available as discrete inputs (function code 02) at bit offsets 0-5, 50, 108-127, 200 and 300. Only the measured values, demand, energy and the transformer/demand settings are listed here; the min/max, limit and communication parameter blocks (offsets 75-201, 63001-63025) follow the same pattern in the manual."
