BACnet_BV
The Binary Value object type (WinCC OA datapoint type) defines a standardized object whose properties represent the externally visible characteristics of a binary value. A "binary value" is a control system parameter residing in the memory of the BACnet Device. This parameter may assume only one of two distinct states. In this description, those states are referred to as ACTIVE and INACTIVE.

(Object/)Datapoint Type Structure
DP_Name.property
| Datapoint Element (Property) | Data Type | Device-depending availability | Description |
| Present_Value | unsigned integer | No | This property reflects the logical state of the Binary Value. The logical state can be either INACTIVE or ACTIVE. Present_Value is optionally commandable. If Present_Value is commandable for a given instance, then the Priority_Array and Relinquish_Default properties are also present for that instance. The Present_Value property is writable when Out_Of_Service is TRUE. |
Faceplate
The state of Present_Value that is shown in the faceplate has the following meaning: green = ACTIVE (1) and gray = INACTIVE (0). When the hand mode is activated, the present state can be changed directly in the faceplate. For more details, see Value Input Panel.
