Analog Value Object
Present_Value of the Analog Value object can be used as Present_Value of both the Analog Input and Analog Output
objects. Present_Value is a Float32(F) numeric value.
The following diagram illustrates the concept when device addresses are allocated to Present_Value of the Analog
Value object and the temperature of an office air conditioner is temporarily lowered from the base temperature
(27.0°C) to 26.5°C.
Example: When #D0000 is allocated to the Present_Value device, #D0010 is allocated to the top device for priority
and trigger, and Float32(F) is allocated to the conversion type, the device addresses are allocated as
follows: #D0000 is the Present_Value for reading, #D0002 is the Present_Value for writing, #D0010 is the
Device for priority, and #D0011 is the Device for write trigger.
Writing the Value of a Device Address to Present_Value
(1) When the value of the Device for write trigger (#D0011) is 1, writes the value of the Present_Value for writing
(#D0002) to the Priority_Array at the index number stored in the Device for priority (#D0010).
(2) The Device for write trigger (#D0011) is automatically reset to 0.
(3) 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.
