Error messages
In case of an error, the addressed node generates a telegram with the "Error Response"
(0x80) command.
The telegram contains the index and subindex of the code in which an error has
occurred.
Bytes 5 ... 8 contain the error code.
– The error codes are standardised in accordance with DS301, V4.02.
– The representation of the error codes is reversed to the read direction (see the
following example).
