Encoded name is a universal format used to reference any object on the BACnet network. The BACnet encoded name consists of the device object instance and the object ID. The encoded name can be used to reference third-party, non-PXC.A devices, or object references external to the ALN.

BACnet supports many object types. In this example, the object is a point.

In this example:

  • BAC identifies this as a BACnet device.
  • 15 is the device object instance, unique throughout the network.
  • AI is the BACnet object type specifier. It identifies the object as a physical Analog Input point.
  • 10 is the BACnet object instance for this Analog Input object. The number is unique for this object type within the BAC_15 device.

Device Specific Name

The BACnet device specific name is a textual representation of an object name that meets the APOGEE PXC.A naming standards. It consists of two parts: the node name of the device and the point system name.

Use the Device Specific Name to identify a point within a specific device when that point meets the APOGEE PXC.A naming standards.

Example:   [AdminBld1] ReturnWaterTemp

Point System Name



Unique BACnet Object Name

You can use the Unique BACnet Object Name to reference objects PXC.A networks only. These PXC.A devices must all be on the same ALN. This format cannot be used to reference objects in non-PXC.A devices.
NOTE: Legacy APOGEE devices are treated as 3rd party references.

Use the BACnet Object Name alone to reference an object when:

  • The object is local to the PXC.A. For example, local automation station I/O and virtual objects.
  • The object exists on a PXC.A on the same ALN.
