No idea what you are talking about there? Joel.

The "System Settings - Other settings - Purge events older than" option works for my purpose. Thank you!

Hello, I am trying the new Mango (core 2.1.3 and BACnet 2.0.3) to discover some BACnet/IP points. I use the MAC address as XXX.XXX.XXX.XXX:47808 and Device instance number. But always got the error: java.net.SocketException: Socket is closed. If I manually input the details of points on this BACnet/IP network, it works fine. But I just could not make the discover working. Could you please help me with this problem? Please let me know if you may need more information about our scenario. Thank you! Best wishes, Pine

The current BACnet I/P implementation has a 1-to-1 relationship between a local device and a UDP port. There are plans to update the implementation to allow multiple devices for one port, but there is no specific schedule at this time for these changes to be made.

No worries. Thanks for following up.

Thanks for the reply. My question is how to setup the VTS IP port since there is no Internet connect... I guess maybe the question should not be in this forum but any chance you know the answer? Thanks a lot!

You should just send a read property to the object with the PID presentValue. Shouldn't matter whether the object is local or remote, depending on what you mean by that of course.

There are two IP addresses you can supply to a local device. The first is a broadcast address. If you don't know what this is, check out this: http://en.wikipedia.org/wiki/Broadcast_address. The second is the local bind address. Often, something like "0.0.0.0" is fine, but if your host is multihomed you may want to be more specific. I recommend you don't set one unless you know why you might have to. Typically you won't create your own remote devices. These are created automatically when you receive IAm messages (in response to your WhoIs).The instance number is an identifier that typically won't change, and so can in many cases be used to uniquely identify a piece of equipment. It is also what is referenced in a WhoIs request when you specify limits. Network is only required when - like you - the BACnet installation consists of more than one network. The network number is then an identifier of the network segment on which the device lives.

There should be a BACnet router that interconnects your IP network and Arcnet. It is supposed to listen to each network, and forward messages between them as necessary. The way a particular BACnet implementation displays the address for a device on a separate network may differ from others. Can you send a wire dump (wireshark works great) of WhoIs from BACnet4J and the response that comes from the Arcnet side?
