BACNET: SETTING NODE_OFFSET TO ASSIGN SPECIFIC DEVICE
INSTANCES
•
After setting a local PC to the same subnet as the ProtoNode (
Section
), open a web browser
on the PC and enter the IP Address of the ProtoNode.
o
If the IP Address of the ProtoNode has been changed by previous configuration, the
assigned IP Address must be gathered from the network administrator
o
The Web Configurator is displayed as the landing page
•
Node_Offset field shows the current value (default = 50,000).
o
The values allowed for a BACnet Device Instance can range from 1 to 4,194,303
•
To assign a specific Device Instance (or range); change the Node_Offset value as needed using
the calculation below:
Device Instance (desired) = Node_ Node_ID
For example, if the desired Device Instance for the device 1 is 50,001 and the following is true:
Device 1 has a Node-ID of 1
Device 2 has a Node-ID of 22
Device 3 has a Node-ID of 33
Then plug the device 1’s information into the formula to find the desired Node_Offset:
50,001 = Node_ 1
50,000 = Node_Offset
Once the Node_Offset value is input, it will be applied to all devices as shown below:
Device 1 Instance = 50,000 + Node_ID = 50,000 + 1 = 50,001
Device 2 Instance = 50,000 + Node_ID = 50,000 + 22 = 50,022
Device 3 Instance = 50,000 + Node_ID = 50,000 + 33 = 50,033
•
Click “Submit” once the desired value is entered.
