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.

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.
