Answer / murali

Try to get the MODBUS communication details,address &
parameters which are all can able to read from the ER300P
meter from your supplier or direct from L&T.
With those inputs we can do anything

Answer / 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.
more details required, pls feel free to ask me

Answer / ab

I'm using this meter to study the power utilization for
several load settings in a complex theromchemical
plant.....At the begning of every measurment I want to
round off the start point of the power consumption reading
to 4 digits (ex:xxxx0000)....so that I can apply my algo on
the readings which I get at the end of my measurement.

Does any one of you know how to do it?

Answer / anbh

Thank you very much George.
As I know from ER300P manual....we have a programing
password with which I can change some settings of the meter
like CT\PT ratio and RTC etc...So can I use the same
programing password to write to the location of current
power consumption?

Thank you again.

With best regards,
Anis
