BOOL_TO_INT(_E)
Outline
This function coverts bit data into word [signed] data, and outputs the data obtained by conversion.
1. Format
*1.
Output variable
2. Set data
In explanation of functions, I/O variables inside ( ) are described.
Explanation of function and operation
This function converts bit data stored in a device specified in
into word [signed] data, and outputs the
data obtained by conversion to a device specified in
.
When the input value is "FALSE", this function outputs "0" as the word [signed] data value.
When the input value is "TRUE", this function outputs "1" as the word [signed] data value.
Cautions
Use the function having "_E" in its name to connect a bus.
