18.1 Device object
Each automation station contains a device object. The device object:
● Contains the device and system information for the automation station
● Is based on the standard BACnet object as defined in the BACnet standard, and contains additional
proprietary properties
● Is always present and is set up in the automation station with initial values
● Is not programmed in the CFC Editor as a function block and is not loaded with the program
You can monitor property values through a BACnet client (e.g., Desigo CC, XWP). You can change default
values. You cannot read changed values back into Xworks Plus (XWP). When an automation station is
replaced, you must reenter any changes made to property values.
