Error messages
If an error occurs in the PROFINET connection during an acyclic property access triggered
by a data record, then the element "PNresp" of the associated reply data record contains the
cause of the error.

In addition to the above-mentioned error messages, other errors may be reported when data
records are accessed, for example, that the specified data record is not present. These
causes of error are described in the SIMATIC S7 documentation.
If the reason for a defective property access lies on the BACnet side, then the element
"BNresp" of the associated reply data record contains a value not equal to 0. The actual
cause of the error is then described in the two elements "ErrorClass" and "ErrorCode". The
meaning of these two elements can be found in the BACnet standard.
