Analog Input Object
Present_Value of the Analog Input object can be set to a fixed value or allocated device addresses and set to the
value of those device address. Present_Value is a Float32(F) numeric value. When device addresses are allocated to
Present_Value, Present_Value is set to the product of those device addresses multiplied by the coefficient.
The following diagram illustrates the concept when device addresses are allocated to Present_Value of the Analog
Input object and the BACnet device reads out the analog input value.
When writing the value of device addresses as Present_Value, Present_Value changes in the following manner.
