Gateway is faulty or is not setup properly.
Refer to the Instruction Manual (this manual) of BACnet
See also A1.Initial setting for PC.
S4.Communication between the B-OWS and BACnet
See A2.Networking Troubles.
S5.B-OWS is faulty or is not setup properly.
Refer to the manual that comes with the B-OWS.
Be sure that settings are correct for connecting with the BACnet
A1:Initial Setting for PC
(1)
Network Setting for the PC
Perform appropriate setting for the transparent connection of UDP/IP unicast and multicast communi-
cation.
●
IP Address / Netmask Setting
●
UDP port 0xBAC0(47808) made available and enabled
When checking whether the UDP port is already in use, execute a "netstat -a" command from the
Windows Command Prompt. At that time, end BACnet
If the UDP port should be in use, stop using the relevant application.
A2:Networking Troubles
(1)
Checking Unicast Communication
®
Ping to/from BACnet
Ex. "Ping 192.168.16.2"
If you get the response, unicast is reachable.
(2)
Checking Broadcast Communication
Trace route to/from BACnet
Ex. "Tracert 192.168.16.2"
Trouble Shooting the Interworking Troubles
®
BACnet
is an open network protocol interpreted and implemented by different vendors.
In some occasions, you may encounter interworking troubles.
If the trouble could not be located in the procedures above, interworking troubles may be suspected.
Analyzing interworking troubles involve capturing BACnet
protocol using tools (ex.Wireshark) and expertise on BACnet
Followings are some hints on the checks you need to perform in order to trouble shoot interworking prob-
lems.
1.
Has B-OWS recognized BACnet
If the B-OWS does not recognize BACnet
ing problem is suspected.
2.
Has B-OWS established connection to the BACnet
If the B-OWS cannot establish connection with BACnet
series of communication), then packets must be captured to see where and what has gone wrong.
(.
Has B-OWS registered units in VRF System correctly?
If the B-OWS cannot register units in VRF System correctly, then registration must be checked first us-
®
ing BACnet
Gateway user interface. If there are no problems on the BACnet
must be captured to see where and what has gone wrong.
4.
What Service is Malfunctioning?
If any service cannot be performed on the B-OWS, then packets must be captured to see where and
what has gone wrong.
