BACnet Commissioning

1. Connect Core Server to BACnet device

Please choose a plan according to your project:

Plan A BACnet network support Internet

  • The Core server shall be in the same network segment as BACnet device. (subnet mask 255.255.255.0).
  • Please use BACnet tools to scan BACnet devices. And ping BACnet devices' addresses to test if communication between Core server and BACnet network is successfully established.
  • Please double check if the Core server is connecting to the cloud by ping 114.215.172.232.

Plan B Add ethernet card if BACnet network not support Internet

  • The Core server shall be in the same network segment as BACnet device. (subnet mask 255.255.255.0).
  • Please add an ethernet card into the Core server to connect Internet. And set Environment Variable ‘BACNET_IFACE’ on server to intranet ethernet card's IP.
  • Please use BACnet tools to scan BACnet devices. And ping BACnet devices' addresses to test if communication between Core server and BACnet network is successfully established.
  • Please double check if the Core server is connecting to the cloud by ping 114.215.172.232.

Plan C Add DTU if BACnet network not support Internet

  • The Core server shall be in the same network segment as BACnet device. (subnet mask 255.255.255.0).
  • Please add a DTU. Set The Core server’s gateway to DTU’s IP.
  • Please use BACnet tools to scan BACnet devices. And ping BACnet devices' addresses to test if communication between Core server and BACnet network is successfully established.
  • Please double check if the Core server is connecting to the cloud by ping 114.215.172.232.

2. Test Connection

If you have trouble in steps below, please send to R&B the screenshots in step 5, troubleshooting and log in step 6.

  1. Please download BACnetScan to test connection.

  2. Double click to run BACnetScan.exe on the Core Server. (Please close the Core and BeOPWatch first. Both software shall not run at the same time with BACnetScan since port will be occupied. Click the Tray-icon on the lower right corner of Desktop to close BeOPWatch program.)

  3. Right click ‘BACnet IP’ in the left and choose ‘Search Device…’

  4. Several devices will appear in the list. Such as 701103 in the figure, right click this device, choose ‘Search Object’, this software will scan all points belong to this device.

  5. Right click a point, and choose ‘Read Properties’. All properties of this point will be listed as figure. The property ‘present-value’ means point value. You can read current value if a connection between Core Server and BACnet device is established. If you cannot read real value please take a screenshot as figure below.

  6. Click ‘Save Log’ in ‘View’ menu in the top to save log file.

Troubleshooting

  • Cannot search BACnet IP device. Some BACnet device do not support full broadcast, such as NAE (Johnson Control). BACnetScan also do not support full broadcast search. If the Core Server has multiple ethernet cards, BACnetScan cannot find any BACnet device. In this case, please choose a right port in ‘BACnet IP Setting’ in ‘Tools’ menu, and search again. Don’t forget to close the firewall when you are using BACnetScan.

  • Found BACnet IP device but found no points. Most possibly you are running other BACnet IP software on the Core Server and UDP port 47808 was occupied so that BACnetScan cannot find any points. In this case, please close that software. (You can check if any ports are occupied by typing ‘netstat -ano’ in Dos Command Window, and send us the screenshot) Two lines of 47808 in the figure means this port is occupied by two software.

  • BACnet IP software cannot run normally when running BACnetScan. Because UDP Port 47808 is occupied by BACnetScan, please close BACnetScan.
