2. Preset/Reset Multi-Register (Function Code 10H)
Set:
Function code 10H allows users to change multiple registers’ content, including
system parameter, time-division energy parameter, initialization energy.
Table 5-6 is an example of It's Total Active Energy is 0.20KWh,Total Active Energy tari
1 is 0.12KWh,Total Active Energy tari 2 is 0.08KWh 17th slave device.

3.Read the relay output state (functional code 01 h)
Query data frames:
Query data frame, the host to send data from the machine frame.01 function allows
the user to obtain the specified address from the machine5.2 the Modbus protocol
communication application format explanation of relay output state ON/OFF (1 = ON, 0 =
OFF), in addition to from the machine address and functional domains, still need to be in
the data eld contains a data frame will be read by the initial address and number of relay
to read.
