Enumerated
Table 23. Properties of the Digital Output object
Note:
Additional properties of the object are saved to maintain the backward
compatibility with the older firmware version. In the new firmware version, each property
has a corresponding BACnet object.
PRESENT_VALUE Property
The property contains the actual value of the digital output. If the DO is in the hand mode,
the actual value of the DO is stored in both PRESENT VALUE property and HAND_STATUS
object.
Digital Output COV
In the firmware versions above 4.0, MIX and MINI modules support COV (change of value).
It means that the module automatically sends the digital output value with every change.
STATUS FLAG Property
The Status Flag property contains information about the status of the object. This
property consists of 4 binary flags. Each flag is described in the table below.
