BACNET PRIORITY ARRAY
BACnet uses a command prioritization scheme for objects that control equipment or software parameters
that affect the operation of equipment connected to devices. The use of this command prioritization scheme
(commonly referred to as Priority Array) allows a device to determine the order in which an object is
controlled. Command Prioritization assigns unique levels of priority to the different types of devices that can
write values to a device. There are 16 prioritization levels with Level 1 being highest and Level 16 the lowest.
For example:

prioritization scheme.
