Note ： 1 、 Read/Write attribute: “ RO ” read only, this parameter use 03H command; “ R/W ”
Read/Write ,system parameter use 10H command, Read in address, which is not listed or without
Read/Write attribute, is forbidden.
2.Meter data adopt fixed_point number, decimal point digital see Address table;voltage/current
harmonic data adopt percentage.
7.5 Communication reading value Vs actual value(Take Val_t as Communication reading
value,Val_sas actual value)
7.5.1Voltage,current,power factor ,frequency
This series measuring value is read out by Modbus-RTU protocol 03 command,each item occupy one
word.Relation between communication value and actual value(secondary side measuring) is shown as below
