Thrown away
| “Thrown away”: On receipt of data from the host computer, only inverters with | |
| specified ID numbers perform the specified operation, while all | |
6 | ||
other inverters throw the data away and move to the ready state for | ||
receiving the next data. |
*: Use terminal boards to branch cables.
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.
