When debugging the BACnet protocol, I encountered the following issue:
I can write to AV (Analog Value) and AO (Analog Output) objects on the Tracer TU software. The Key Usage column in the Tracer TU software has two states: "Display Status" and "Control Device". However, when I scan for object information on the Tracer TU software, the AV and AO objects show "Display Status", while they should correctly be "Control Device".
Other writable objects, such as MV (Multi-state Value) and BV (Binary Value) objects, can normally display the "Control Device" status in the Key Usage list.
What should I do to make the AV or AO objects normally display "Control Device" when scanned in the Tracer TU software? Or do AV or AO objects not support this status?
I don't know what determines the "Control Device" status in the Tracer TU software. Could you tell me the reason for this issue?
