Communication concept
The communication is a data communication based on a
request/response dialog, whereby the host delivers the
requests and the instrument provides responses.
Following a request from the host, the instrument will
transmit a specific response message.
Assuming there are no transmission errors and the
message can be handled correctly, the instrument will
respond with a positive acknowledgment message.
If an error occurs for any reason, the instrument will
respond with a negative acknowledgment message.
If the host does not receive a response upon a request
within a certain time, a timeout should be activated.
