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
