Analog Output Object
Present_Value of the Analog Output object can be allocated device addresses and set to the value of those device
addresses. Present_Value is a Float32(F) numeric value. When device addresses are allocated to Present_Value, the
product of Present_Value multiplied by 1/coefficient is stored in the device addresses.
The following diagram illustrates the concept when device addresses are allocated to Present_Value of the Analog
Output object and the BACnet device writes the analog output value.
When reading out Present_Value to device addresses, you must be aware of the data type. Depending on the data
type of the device addresses, the value is stored in the device addresses as follows. Set the data type according to the
value of Present_Value. The data type of Present_Value is set in “Conversion type” on page 3-115 of the “Analog
Output Object”.
