Environment

SmartStruxure 1.3, 1.4 BACnet Integration

Cause

The BACnet device instance number is unique within a BACnet internetwork. There may be a need to find out or change the device instance number to ensure there are not duplicates. 

Resolution

When a BACnet Interface is added to an AS or ES, the AS or ES will become a BACnet device and it will have an instance number (automatically generated or manually assigned). 

  • To check an ES or AS BACnet device instance number, go to the properties of the BACnet Interface and then the Advanced tab. The device instance number is the Object ID.
  • To check a BACnet device, go to the properties of the BACnet Device and then the Advanced tab. The device instance number is the Object ID. 

The valid range of instance numbers for a BACnet device is 0 to 4194302.
