4.1.5. Errors referred to the communication
o
Err11: ILLEGAL FUNCTION
Not valid function. The received function code is not allowed for the
slave. This is possible because the code is only for newer elements
and it is not implemented in the selected unit. Also it can indicate
that the master or the slave is in a wrong status for the processing of
this type of functions (for example, because the device is not
configured and registers values are being asked to it).
o
Err12: ILLEGAL DATA ADDRESS
The received data address is not an address allowed for the master
or the slave. In detail, the combination of the reference number and
the transferred length is not valid. For a controller with 100 registers,
a request with an offset of 96 and length of 4 will operate correctly,
but a request with an offset of 96 and length of 5 will generate an
exception code 12.
o
Err13: ILLEGAL DATA VALUE
A value contained in the data field of the request is not allowed for
the master or the slave. This indicates a fault in the remainder
structure of a complex request, therefore, the implicated length is
not correct.
o
Err14: SLAVE DEVICE FAILURE
Non-recoverable error has been produced while the master or the
slave was waiting for executing the requested action.
