We have schneider 6400 and L&T ER300P smart meters which are connected to GTI (Grid-tie inverter) . We planned to get data centralised through prolific based converter (rs485 to serial) and libmodbus library. But data getting from ER300P is awkward (long integer data in register 40001 or 40002), but schneider responds. Please help to collect the data (Voltage , current , power , frequency) from ER300P.
