Binary Input Object
Present_Value of the Binary Input object can be set to a fixed value or allocated to a bit device address and set to the
value of that bit device.
The following diagram illustrates the concept when an external input is allocated to Present_Value of the Binary Input
object and the BACnet device reads out the state of the external input.
The following table shows Present_Value, Polarity, and the physical state of the input.
