Explanation of function and operation
This function converts bit data stored in a device specified in into word [unsigned]/bit string [16-bit] data,
and outputs the data obtained by conversion to a device specified in .
When the input value is "FALSE", this function outputs "0H" as the word [unsigned]/bit string [16-bit] data
value.
When the input value is "TRUE", this function outputs "1H" as the word [unsigned]/bit string [16-bit] data
value.
Cautions
Use the function having "_E" in its name to connect a bus.
