7-2 Exception Responses
If the controller receives a message which contains a corrupted character (parity check error, framing error etc.), or if
the CRC16 check fails, the controller ignores the message. However, if the controller receives a syntactically correct
message which contains an illegal value, it will send an exception response, consisting of five bytes as follows:
slave aoffset function code + exception code + CRC16 Hi +CRC16 Lo
Where the offset function code is obtained by adding the function code with 128 (ie. function 3 becomes H'83), and
the exception code is equal to the value contained in the following table:
Exemption Code
Name
Cause
1
Bad Function Code
Function code is not supported by the controller
2
Illegal data address
Register address out of range
3
Illegal data value
Data value out of range or attempt to write
a read-only or protected data
