Writing a Value to Present_Value from the BACnet Device
BACnet device
(2)
Write value:
26.5
(1)
Priority:
1
(1) The BACnet device writes the write value (26.5) to Priority_Array at the index number indicated by the specified
priority (1).
(2) Priority_Array with the smallest index number out of all non-NULL(00h) values is element 1 (26.5), so 26.5 is used
as the value of Present_Value.
(3) Present_Value (26.5) is written to the Present_Value for reading (#D0000).
Element 1 (26.5) of Priority_Array is used as the value of Present_Value until it is reset to NULL(00h). When
element 1 is reset to NULL(00h), element 3 (27.0) is used as the value of Present_Value.
For how to write NULL(00h), refer to "Analog Value Object" in "Top device for priority and trigger" on page
3-117.
