Resolution
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.
This is not an error. BACnet clients often poll
all properties of a particular object to
determine which properties are supported.
This is not an error – the BACnet client will
use a different method to read data from the
FieldServer.
You should not see this message. It normally
indicates a configuration error.
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.
This may be a problem on the Client system.
Consult the PIC statement to determine what
services are supported.
