BACnet: Setting Node_Offset to Assign Specific Device Instances
•
Follow the steps outlined in
Section
to access the ProtoCessor Web Configurator.
•
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 is 50,001 and the following is true:
▪
Device has a Node-ID of 1
Then plug the device’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 as shown below:
▪
Device Instance = 50,000 + Node_ID = 50,000 + 1 = 50,001
•
Click “Submit” once the desired value is entered.
