Negative answers:
If a client sends a request to the server, he expects an answer. Four situations may occur:
• If a server receives a request flawlessly and is able to process it normally, it returns a normal answer to the client.
• If a server does not receive a request due to a communication failure, it does not return any answer. On the side of the client, the time limit for answer receipt
expires.
• If a server receives a request but detects a communication failure (parity, CRC...), it does not return any answer. On the side of client, the time limit for answer
receipt expires.
• If a server receives a request flawlessly but is not able to process it normally, it returns a negative answer to client, while giving a reason for the failure.
A normal and negative answer are different by the highest bit of the function code. If the bit is null, it is a normal answer, if the bit is set, it is a negative answer.
In case of a negative answer, there is a failure code forwarded in the data part. There is a list of possible failure codes in the following table.
