IF96012 module Memory + RS485 communication
It makes available by RS485 communication the main data concerning carried out measure-
ments as well as configuration parameters (
Thanks to the internal storage, it is possible to store the energy counts of the main measured
parameters. A simple formulas that the user should use in order to obtain the max saving
interval is:
Floor
= Function that takes only the integer quotient
Rlength = Record lenght in bytes
Time
= Time interval in seconds
sec
