present-value

PrVal

Present value

A writable standard BACnet property that indicates the current logical value of the output.
The logical value ranges from 1 to n, where n is equal to the number of states defined.

priority-array

PrioArr

Priority array

A read-only standard BACnet property contains prioritized commands that are in effect for this object. A BACnetPriorityValue is either an Unsigned value or null.
Unsigned values shall range from 1 to n, where n is equal to the number of states defined in the number-of-states property.

Present-Priority

PrPrio

Present priority

A read-only standard BACnet property indicates the highest priority slot (1-16) in the priority-array with a non-null value. If all slots in the priority array are null, DS1_Present-Priority shall have the value 17.

relinquish-default

DefCmd

Default command

A writable standard BACnet property that provides the default value for present-value property when all slots in the priority-array are null.
Unsigned values shall range from 1 to n, where n is equal to the number of states defined in the number-of-states property

number-of-states

NumSta

Number of states

A read-only standard BACnet property that defines the number of states the present-value may have. MultistateProcessValue objects:

The number-of-states property can range from 2 to 256.

The number-of-states property must be defined at object creation time. The number-of-states property is read-only in instantiated objects.

state-text

StaTxt

State text

A writable standard BACnet property that provides descriptions of all possible states of present-value. The size of the state-text array is defined by the number-of-states property. The present-value, interpreted as an integer, serves as an index into the array.
The length of the state-text array is defined at object creation time.

Alarm-Extension

AlarmExtn

Event configuration

A writable enumerated proprietary property that specifies whether the optional intrinsic alarming extension is enabled for the object.
