Depending on the data type of the allocated device addresses, Present_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 3-118 of the "Analog Value Object".
Additionally, when writing the value of device addresses to Present_Value, Present_Value changes in the following
manner.
Data Type Present_Value of BACnet Device × (1/Coefficient) Value of Device Addresses
UBIN16(W)
Value within range of 0 to 65,535 Present_Value
Value outside range of 0 to 65,535 0
BIN16(I)
Value within range of -32,768 to 32,767 Present_Value
Value outside range of -32768 to 32,767 0
UBIN32(D)
Value within range of 0 to 4,294,967,295 Present_Value
Value outside range of 0 to 4,294,967,295 0
