Binary Objects support custom Active and Inactive Text.
•
BACnet/IP supports COVs.
11.3.3.2
BACnet Objects
The BACnet server hosts BACnet objects which contain many different properties
for any BACnet client on the network to access. The gateway supports seven
different BACnet objects: Device, Analog Input, Analog Output, Analog Value,
Binary Input, Binary Output, and Binary Value. All supported properties of these
objects are readable, while only the present value property is writable (for
Outputs and Values only). Refer to section 11.3.1 for the list of properties each
object supports. The objects and their properties are configured using the
configuration utility (or, optionally, via the web interface for BACnet IP). Refer to
sections 8.7.2 and 8.8.3.3 for more information on configuring BACnet objects.
