Values are mostly 32-bit integers sent low word first with fixed weights; functions 03 and 04 are equivalent and up to 125 registers can be read at once. This map covers voltages, currents, powers, PF (both sign conventions), frequency, energy totals and partials, run hours, THD, demand and max values, output/alarm status, alarm and pulse-output setup, serial settings, resets and device state.",
