Review comment:
Just today did I push some changes that should help greatly with the
decoding of errors in S7 ... the main problem was, that in case of an error,
the response is not a S7MessageResponseData type, but a S7MessageResponse
(without Data) ... I changed the code to wait for a S7Message with the given
PDU Id and to handle that then ... so I think most bad errors were due to this
... perhaps the problem now will go away.
