Hello,
I am implementing MODBUS RTU over serial line (rs232, and later also rs485).
I have read the specification and found nothing stating that the Master should always wait for a response from the slave before sending another request. So, I am considering the case where the Master sends multiple requests, and then the slave processes them one by one, and then sends back the response for all the received requests.
Should I consider this case while implementing MODBUS or should I simple implement the case where Master sends one request, waits for the response from slave (till timeout) and then sends the next request and so on.....
