Appendix D.4. BACnet Specific Statistics
Stat Description Resolution
Link Control
A “who-is” link control message was
send or received.
It is normal to receive a few link control
messages. If the number is higher than the
transmit/receive messages, however, there may
be a problem with lost communications..
Unsupported
Properties A request for an unsupported property
was received
This is not an error. BACnet clients often poll all
properties of a particular object to determine
which properties are supported.
Segmentation
Not Supported
Data was requested but the response
would have exceeded the maximum size
of the APDU and could not be sent using
an un-segmented message.
This is not an error - the BACnet client will use a
different method to read data from the
FieldServer.
Sequence Error
Invoke ID of a reply did not match the
Invoke ID of the poll. You should not see this message. It normally
indicates a configuration error.
Write Access
Denied
A write to an object was denied.
This typically happens when trying to write to an
Input Object that is not Out-Of-Service. It is not
possible to write to Input Objects.
Exception Errors
A BACnet Service was denied because it
is not supported
This may be a problem on the Client system.
Consult the PIC statement to determine what
services are supported.
