Device object
Device object properties
Every BACnet device object and also therefore the PN/BACnet LINK has a device object as
logical representation of the device. This object specifies the basic properties of a BACnet
device. Devices in the BACnet network can read out the properties of a BACnet device. For
example, as a BACnet client, the PN/BACnet LINK is able to read the device object from
other devices in the BACnet network.
The following table shows which properties are supported for the device object of the
PN/BACnet LINK and from which source the associated values originate.
