Data on communication failure information description (fault code) :
Communication fault message (fault code) : when the slave device responds, function code field
and fault address are used to indicate whether it is a normal response (correct) or an error (called
exception response) . If it is the normal response, the slave device will respond corresponding
function code and data address or sub-function code. If it is the exception response, the slave device
returns a code equivalent to the normal code, but the first position is the logic 1.
For example: a message sent from one master device to one slave device is required to read a
set of inverter function code address data, it will produce the following function code: 00000011
(hexadecimal 03H), for the normal response, the slave device will respond the same function code.
For the exception response, it returns: 10000011 (hexadecimal 83H) . In addition to the modification
to function code for exception, the slave device will respond to a byte of exception code, which
defines the reason for exception occurrence.
When the application program of master device gets a exception response, the typical handling
process is to resend the message, or change corresponding fault command.
