10.4 Error list
If the controller encounters an error when processing the query, it returns the exceptional response instead of
the normal one to the terminal. An exception has always the value 2 (Illegal Data Address). After receiving the
exceptional response, the terminal should read the communication object 24523 containing the last error
specification. The meaning of an error can be found out from the following table.
