Binary Value Object
Present_Value of the Binary Value object can be used as Present_Value of both the Binary Input and Binary Output
objects.
The following diagram illustrates the concept when an internal relay is allocated to Present_Value of the Binary Value
object and the office lights are temporarily turned on from off.
Example: When #M0000 is allocated to the Present_Value device and #D0010 is allocated to the top device for
priority and trigger, the device address are allocated as follows: #M0000 is the Present_Value for reading,
#M0001 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
(#M0001) to the Priority_Array at the index number stored in the Device for priority (#D0010).
(2) The value of 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 (1), so 1 is used as the
value of Present_Value.
