5 BACNET MS/TP AND BACNET/IP: SETTING NODE_OFFSET TO ASSIGN SPECIFIC
DEVICE INSTANCES
•
After setting a local PC to the same subnet as the ProtoNode (Section
on the PC and enter the IP Address of the ProtoNode; the default address is 192.168.1.24.
•
If the IP Address of the ProtoNode has been changed by previous configuration, the assigned IP
Address will need to be obtained from the network administrator.
•
The Web Configurator will be displayed as the landing page.
•
Node_Offset field will be presented displaying the current value (default = 50,000).
•
Change the value of Node_Offset to establish the desired Device Instance values, and click
SUBMIT.
o
Given that: Device Instance = Node_Offset + Modbus Node_ID
o
Then: Node_Offset (required) = Device Instance (desired)
For example, if the desired Device Instance for the 1
o
Device 1 has a Modbus Node-ID of 1
o
Device 2 has a Modbus Node-ID of 22
o
Device 3 has a Modbus Node-ID of 33
o
Node_Offset (required) = 1,001
1,000 NOTE: The Node_Offset value will be applied to all devices.
o
Device 1 Instance will then be = 1,000 + Modbus Node_ID = 1,000 + 1 = 1,001
o
Device 2 Instance will then be = 1,000 + Modbus Node_ID = 1,000 + 22 = 1,022
o
Device 3 Instance will then be = 1,000 + Modbus Node_ID = 1,000 + 33 = 1,033
–
(Modbus Node_ID) = 1,001
