Auto-Configure |
Auto-Configure allows the user to automatically identify devices on the BACnet network and select the device objects required for their application. BAC uses the WhoIs object type to search the network to identify devices. It then uses the Device object to list all objects provided by each device. The user can select objects from the list that are required for his/her application. |
