“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 move to the ready state for
receiving the next data.
*: Use terminal boards to branch cables.

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