5.4.2 BACnet IP settings
P5.8.3.1.1 I
NSTANCE NUMBER
Similar to BACnet MS/TP device object instance number (see page 20).
P5.8.3.1.2 C
OMMUNICATION TIME
-
OUT
BACnet board initiates a communication error if the Ethernet connection is lost. Communica-
tion time-out parameters define the minimum delay between UDP packages received from the
master. The timer is reset and started after each received UDP package. This parameter can
be used if the master is periodically polling the slaves.
P5.8.3.1.3 P
ROTOCOL IN USE
BACnet/IP protocol can be enabled and disabled with this parameter. When the parameter val-
ue is set to
"1" the BACnet/IP protocol is enabled and disabled when set to " 0 ".
P5.8.3.1.4 BBMD IP
ADDRESS
BACnet/IP broadcast management device IP address.
P5.8.3.1.5 BBMD UDP P
ORT
BACnet/IP broadcast management device UDP port.
P5.8.3.1.6 T
IME TO
L
IVE
The Time-to-Live value is the number of seconds within which a foreign device must re-register
with a BBMD. The value also applies as the interval for transmitting the Register-Foreign-De-
vice message to BBMD device. "
0
" means not in use.
5.4.3 BACnet IP monitoring values
P5.8.3.2.1 F
IELDBUS PROTOCOL STATUS
Fieldbus Protocol Status tells the status of the protocol.
P5.8.3.2.2 C
OMMUNICATION STATUS
The Communication status shows how many error and how many good messages the frequen-
cy converter has received. The Communication status includes a common error counter that
counts CRC and parity errors and a counter for good messages.

written to parameter P5.8.3.1.1.
Bad Frames Good messages
0…99
Number of messages received
with errors
0…999
