BACnet Instance The number used by a BACnet master for polling data from
the Protocol Converter.
Possible values include Analog Instance (AI) or Binary
Instance (BI).
BACnet Engineering Units In the BACnet ASHRAE standard, numbers correlate with
units of measure. Refer to the BACnet ASHRAE standard
for more information.
BACnet COV Client
(COV - Change of Value) The IP address of the BACnet master that is polling the
FDS-PC.
BACnet COV SPID Enter the Subscriber Process Identifier.
You’ll also need to designate if it should be Confirmed or
Unconfirmed.
Confirmed: When a change of value is sent to the device, it
will look for an acknowledgement of the change to be sent
in response. If no acknowledgement is received, the
change will be sent again. This cycle will repeat until an
acknowledgement is received.
Unconfirmed: A change of value is sent, and the device
doesn’t look for an acknowledgement.
Select the Confirmed or Unconfirmed radio button to
indicate your preference.
BACnet COV Increment Amount that the present value of a point needs to change
before the change of value message is initiated to the
BACnet master.
BACnet COV Period Interval, in seconds, between polling operations.
