“Thrown away”:On receipt of data from the host computer, only inverters with
specified ID numbers perform the specified operation, while all
other inverters throw the data away and mov e to the ready st ate for
receiving the next data.

①The host computer sends data to all inverters on the network.
②On receiving the data from the computer, each inverter checks the inverter ID number
contained in it.
③Only the inverter with the specified ID number (No. 3 in this case) decodes the command and
performs the specified operation.
④No. 3 inverter sends the processing results to the host computer, along with its ID number.
⑤Thus, only No. 3 inverter operates in response to the operation frequency command from the
host computer.
