Response:
The response to the load profile query contains device
address, function code and number of bytes data each
of 1 byte, and then the requested parameters of 4 bytes
each. Each parameter represents data over a period of a
day when daily log is accessed and represents data over
a period of a month when monthly log is accessed.
The response ends with 2 byte CRC.
Note: If a user tries to access the data which is out of the range of the datalog i.e. more than 1 year before the
present date for daily log and more than 14 years before the present date for monthly log, it will result in a modbus
exception. The same will occur if a user tries to access the data before the starting date of the corresponding log or
a future date.
