BACnet MS/TP and BACnet/IP (FPC-N34): Setting the Device Instance (Node-ID)

• The A Bank of DIP switches are also used to set the BACnet Device Instances.
• The BACnet Device Instance can range from 1 to 4,194,303.
• The BACnet device instances will be calculated by taking the Node_Offset (default is 50,000) found in
Web Configurator (Section 2.3.2.1) and adding it to the value of the A Bank DIP switches (MAC
address). When more than one device is connected to the ProtoNode, the subsequent BACnet
Device Instance numbers will be sequential from the first/previous device.
For example:
• Given that: Device Instance = Node_Offset + MAC address
Default Node_Offset value = 50,000
o
A Bank DIP switch (MAC address) = 11
o
Then the Device Instance values for the devices are:
•
o Device 1 Instance = 50,011
Device 2 Instance will then be 50,011(Device Instance 1) +1 = 50,012
o
o Device 3 Instance will then be 50,012 (previous Device Instance) +1 = 50,013
2.3.3.1 BACnet MS/TP or BACnet/IP:
• With the default Node_Offset value of 50,000 the Device Instances values generated will be within the
range of 50,000 to 50,127.
• 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.
Methods for changing the Node_Offset value are provided in Section 4.2
•
o This step cannot be performed until after the unit is connected and powered.
