Supported diagnostic sub-functions
It is possible to obtain diagnostics from the mMINT or an attached
INCOM product using function code 08 . See
Table 6
. A single
register is used for each UART counter within the mMINT . Each
INCOM device and the mMINT contain a unique slave counter .
To use mMINT address 247 or 248 in the diagnostic query, SW2-1
must be properly set . See Section 5 and
Table 5
.

Exception codes
Under certain circumstances, the mMINT will return an
exception code .
If the function in the query is not supported by the mMINT,
exception code 01 is returned in the response .
If the data (object) register is illegal, exception code 02 is returned in
the response .
If the data value in the query is illegal, exception code 03 is returned .
If the slave INCOM product fails (usually a timeout), exception code
04 is returned .
In certain circumstances, an exception code 05 (ACK) is returned .
If the mMINT cannot perform the requested function, exception
code 07 (NAK) is returned .
If only a partial register is used in the query, exception code 84
is returned .
