Answer Posted / pearl george
there are so many softwares available on the net such as modscan, simplymodbus by which u can communicate. rs485 port uses the modbus rtu mode of communication in L&T er300p.with these softwares u can get the values like voltages, current, pf, frequency etc that are stored in the holding register of the meter. to communicate with the energy meter u hav to prepare a query with the required function code.
