| 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. |
