specific priority array from 1 to 16. As per the BACnet standard, when a controller receives an unspecified
write command, the controller automatically assigns it to priority array level 16.
As such, the controller now has an entry in priority array 16 of an object which effectively overrides it and by-
passes the local control application program.
If the intent of the central logic block or sequence is simply to reset local values and still allow local users to
change certain settings (such as setpoints and system mode for example) then the easiest way is to bind the
logic block to the BACnet relinquish default property value as described below.
Adding the relinquish default object property for binding
In the Niagara point manager under the device, click on the plus (+) icon to expand all the options and
properties of the desired object.
Locate the relinquish default property value and add it to the local server database of proxied objects.
Make sure it is added as a writable object and that it is enabled.
