The contents of one log
Users can select any parameters they want to log from the 13 parameters. In order to
generate historical logs for the selected parameters, users should program the meter so
that selected parameters from the corresponding Modbus registers can be copied to the
historical log record. That is to say, if you want to log a certain parameters, only need to set
the corresponding Modbus address in the register of data logging. One parameter in the
meter is taking up two Modbus registers. The 13 parameters are voltage, current, power,
import energy, export energy, total energy, net energy, , import Ah, export Ah, total Ah, net
Ah, DI1 count value and DI2 count value.
For example” log the current data, register 0200H and 0201H programmed to be
recorded.
The number of Registers in a log
