In the EcoStruxure Building Operation "EBO" software, BACnet devices and objects use references to make a connection between two or more variables for data exchange. For example, you can create a reference for a setpoint property in a device. There are two ways to configure a reference on a network:
• System reference: Use this standard method to create a path-based reference to an object or property that is currently located on the EcoStruxure BMS server.
• BACnet reference: Use this method to create a reference that uses the elements of a property value (Device instance number, Object type, or Object instance number) to identify a BACnet object or property that is not currently on the EcoStruxure BMS server but may be uploaded or imported to the server later. You can also use this method to reference a BACnet object or property on an external device.
After you create the reference, the system automatically fills in the available information. If any information is missing in the BACnet reference, you may need to download or upload the device.
