• A communication check can be made since the query message is sent and the query message is returned as it is as the
return message (subfunction code H00 function).
Subfunction code H00 (Return Query Data)
• Query message
• Normal response (Response message)
• Query message setting
• Content of normal response
With a normal response, the content is the same as a to d (including the CRC check) query messages.
NOTE
• With broadcast communication, no response is generated even if a query is executed, so when the next query is made, it
must be made after waiting for the inverter data processing time after the previous query is executed.
