4.4.1 Setting the Device Instance for BACnet/IP Network
• The BACnet Device Instances will be calculated by adding the Node_Offset (default
value is 90,000) to the unique device's Node ID (See Section 5.2).
• The Node_Offset is found in the Web Configurator.
• The BACnet Device Instance can range from 1 to 4,194,303.
• To assign specific Device Instance values, change the Node_Offset value.
(Section 5)
Example:
o
Node_Offset value (default) = 90,000
o
Device 1 has a unique Node-ID of 1
o
Device 2 has a unique Node-ID of 22
o
Device 3 has a unique Node-ID of 33
o
Given that: Device Instance = Node_Offset + unique Node_ID
o
Device Instance, Device 1 = 50,000 + 1 = 90,001
o
Device Instance, Device 2 = 50,000 + 22 = 90,022
o
Device Instance, Device 3 = 50,000 + 33 = 90,033
4.4.2 Setting the Device Instance for BACnet MS/TP Network

o
Device Instance, Device 3 = 50,000 + 33 = 90,033
