BACnet

BACnet is a facility-management protocol. The 'outside-cooling' uses BACnet over IP. The Protocol is transmittet via UDP-packets.

BACnet4linux

The BACnet4linux publishes Information gatherd over Backnet in a html-file. It can be accessed over a specific port (in this case 8000).

 ./bacnet4linux  -h8000 -D1 -c1 -e1 -ieth0

Just click on the Decive-number (in our case 10) on the lefthand side of the html page.

Problems

At The moment the program crashes due to a 'Speicherzugriffsfehler'. This may be due to the other BACnet-polling computer on the net.

BACnet-stack

This is a more recent Release from a different Project.

 ./whois/bacwi *

Lists all available BACnetDevices on the net. Fro example:

 Device  MAC            APDU SNET  SADR          
 ------- -------------- ---- ----- --------------
      10 016419ACC0BA    480     0 

Object-List:

 ./epics/bacepics 10

Lists all Objects of the Device 10. Unforunately our DCC_4000 does not support Segmentation and no object-list is generated. Only basic information is displayed.

DCC 4200

The Web Interface seems to have a problem with ssh-tunnel. Wired directly to the system, I had no problem neither with Firefox nor Safari. The Java-application just forwards the display-panel's information. Nothing more.
